9 video chat apps compared: Which is best for security?

There is no single most secure video-chat app. Signal is the best default for sensitive personal calls; FaceTime is the best choice for Apple-only groups; WhatsApp is the easiest cross-platform compromise; Jitsi Meet is the best no-account or self-hosted option; and Wire is the strongest specialist choice for privacy-focused businesses. Zoom, Microsoft Teams, Google Meet, and Cisco Webex are excellent managed meeting platforms, but their ordinary meeting modes are not automatically end-to-end encrypted.

This updated comparison replaces Tauria with Jitsi Meet because Tauria Video Conference ceased operations on June 1, 2026. Product limits and availability below reflect vendor information checked through August 9, 2026, but plans, features, and regional rollouts should be verified again before making a security-critical decision.

What secure video calling actually means

Video-call security is not one feature. A service can encrypt a call while it travels across the internet yet still hold the keys, collect detailed metadata, allow uninvited people into a meeting, or store recordings and transcripts in an administrator’s cloud account.

Evaluate these properties separately:

• Encryption in transit: protects traffic between participants and the provider’s infrastructure, or between service relays. It prevents ordinary network interception but does not necessarily prevent the provider from accessing the media.
• Encryption at rest: protects stored recordings, messages, files, transcripts, and account data on servers or cloud storage.
• End-to-end encryption, or E2EE: is designed so the service does not possess the keys needed to decrypt the call’s media. It protects the content from the service provider, but only when the correct secure mode is enabled and all participants use compatible clients.
• Client-side encryption: lets an organization control or supply encryption keys. The exact trust model depends on the product, identity provider, key-management system, and features enabled.
• Provider-blind or zero-knowledge encryption: is a stronger claim that the provider cannot decrypt protected content. Do not assume that every product using the phrase end-to-end encryption makes this claim in every mode.
• Authentication: helps establish that an account, device, or participant is associated with the expected identity. A meeting passcode alone does not authenticate a person.
• Meeting access control: includes passcodes, unpredictable room names, waiting rooms, lobbies, host admission, authenticated-user restrictions, CAPTCHA or verification checks, meeting locks, and the ability to remove participants.
• Metadata privacy: concerns who called whom, when, from which device or IP address, with what phone number, and how long those records remain available.
• Endpoint security: covers the participant’s phone, computer, browser, microphone, camera, account, and physical surroundings. Encryption cannot protect audio captured by malware before encryption or after decryption.
• Participant trust: an admitted participant can record the screen, use another device to record the room, take screenshots, or repeat what was said. E2EE does not prevent that.

The most important question is therefore not simply whether an app says it is encrypted. Ask: Can the provider decrypt this particular call, in this particular mode, with these particular participants and features enabled?

At-a-glance comparison

The table describes the principal call modes, not every plan or account type. Limits and feature availability can vary by subscription, client, operating system, country, and organizational policy.

For the historical nine-app premise and its December 2021 publication date, see the original CSO comparison. Tauria is no longer a current option; its closure notice says operations ended June 1, 2026.

The nine apps, reviewed

1. Signal — best for highly private personal calls

Security model

Signal is the strongest default recommendation for sensitive personal calls when every participant is willing to use it. Signal calls are end-to-end encrypted, and its group video calls support up to 75 participants. Signal’s documentation says participants in the ordinary group-call flow must use the latest version and belong to the same Signal group. See Signal’s group video-calling documentation.

Signal is designed so the service cannot decrypt call content. That does not make the caller anonymous, prove that a contact is genuine, or protect an infected phone.

Privacy and identity

Signal accounts are registered with a phone number, but users can limit phone-number visibility and discoverability and use an optional username. For a high-risk conversation, open the contact profile, choose View Safety Number, and compare the safety number or QR code with the other person through a separate trusted channel. This helps detect impersonation or an unexpected identity change.

Signal does not turn E2EE into complete metadata anonymity. Registration information, contact relationships, device state, timing, and network information still belong in the threat model. For phone-number controls and usernames, see Signal’s phone-number privacy guide.

Practical account controls

• Open Settings → Privacy → Phone Number and choose the visibility and discovery settings appropriate to your contacts.
• Compare a contact’s safety number or QR code before a sensitive call.
• Enable registration lock in Signal’s account or security settings.
• Review Linked devices and remove anything unrecognized.
• Keep the app and operating system current.

Best for

Private one-to-one calls, family or activist groups that can agree on one app, and conversations where provider access to live media matters more than business features.

Avoid if

You need a drop-in browser meeting, telephone dial-in, enterprise scheduling, cloud recording, AI summaries, large webinars, or extensive moderation and compliance tooling.

Verdict

Choose Signal for the best general privacy posture in a personal call, provided participants verify one another and secure their devices.

2. FaceTime — best for Apple-only groups

Security model

FaceTime calls are end-to-end encrypted, and Apple says it does not store FaceTime call content. Group FaceTime supports up to 32 participants. Apple’s FaceTime privacy documentation also says Apple retains limited usage information, including attempted-call and invitation-related information, for up to 30 days. That is why E2EE should not be interpreted as zero metadata.

Platform and access controls

FaceTime is no longer strictly Apple-device-only. An iPhone, iPad, or Mac user can create a FaceTime link, and Android or Windows participants can join through a current Chrome or Edge browser. Web participants enter a name and wait for the host to admit them. Apple documents the browser-joining process.

Web participants have fewer capabilities: SharePlay and screen sharing are unavailable on the web. A FaceTime link should be treated like a meeting credential. Do not post it publicly, and remove or stop using a link that has been widely shared.

Best for

Apple households, small family groups, and Apple-only organizations that want E2EE without configuring a separate service.

Avoid if

Your group uses many non-Apple devices, needs business recording or transcription, requires detailed enterprise administration, or needs more than 32 participants.

Verdict

FaceTime is the simplest secure choice when nearly everyone is already in the Apple ecosystem. Signal offers more deliberate identity-verification and phone-number privacy controls, while FaceTime offers easier adoption for Apple users.

3. WhatsApp — best cross-platform privacy and convenience compromise

Security model

Personal WhatsApp messages and calls are end-to-end encrypted by default. WhatsApp also provides two-step verification, disappearing messages, blocking and reporting, Privacy Checkup, and Silence Unknown Callers. Its official security material is about personal WhatsApp use; business and API arrangements can have different data-access conditions. See Meta’s explanation of WhatsApp business conversations.

WhatsApp announced browser-based audio and video calling, including group calls, screen sharing, reactions, and a Calls tab, in July 2026. The feature is rolling out gradually, so availability should be checked in the current WhatsApp Web calling announcement and the Help Center before publication. Do not promise a universal web participant limit.

Privacy and account risks

WhatsApp protects personal call content, but it is not a minimal-metadata service. Phone-number registration, contact discovery, account and device data, call history, backups, and the wider Meta ecosystem may matter to a privacy-sensitive user. A SIM swap or stolen verification code can also become an account-takeover path.

Practical account controls

• Enable two-step verification.
• Run Privacy Checkup and review profile, group, call, and status visibility.
• Enable Silence Unknown Callers.
• Review Linked Devices and remove old or unfamiliar sessions.
• Open Chats → Chat backup → End-to-end encrypted backup and enable the protected-backup option where available.
• For high-risk accounts, check whether Settings → Privacy → Advanced → Strict Account Settings is available on the current app version and in your region. Meta describes that feature in its security announcement.

Best for

Families, community groups, and personal contacts spread across Android, iPhone, and—in accounts where the rollout is available—web browsers.

Avoid if

You need to hide your phone number, avoid a large platform’s metadata ecosystem, run a controlled business deployment, or require a formally verified identity model.

Verdict

WhatsApp is the most practical cross-platform compromise for personal calls. It provides stronger default call-content protection than ordinary managed-meeting modes, but its privacy story is broader than E2EE and includes phone-number, backup, metadata, and account-security decisions.

4. Wire — best for security-focused business collaboration

Security model

Wire says that messages, media, and calls are end-to-end encrypted. Its calling documentation describes SRTP with DTLS for call encryption, and Wire supports device or conversation verification to help users detect impersonation and man-in-the-middle risks. See Wire’s security explanation.

Wire is also attractive to organizations that need deployment control. It offers cloud and on-premises options, allowing a customer to select a deployment model that fits data-sovereignty and operational requirements. Self-hosting is not free security: the organization becomes responsible for patching, authentication, logs, backups, monitoring, availability, and incident response.

Capacity and plan caveat

Wire’s current pricing information lists video conferences of up to 150 participants on the SMB plan, while older support documentation lists a 50-participant conference limit. That discrepancy illustrates why conference capacity must be tied to the current plan and date rather than copied as a permanent product fact. Wire’s support documentation also says conference initiation is restricted to enterprise use. Check the current pricing page and conference-calling documentation.

Wire distinguishes calls and messages from some Wire Drive file and folder functions, so do not assume every storage feature has exactly the same provider-blind properties as live calls.

Best for

Businesses that prioritize always-on E2EE, open-source transparency, device verification, administration, data sovereignty, or on-premises deployment over mass-market adoption.

Avoid if

Your participants are unlikely to install a less familiar app, or you need a huge public meeting with casual guests and broad interoperability.

Verdict

Wire is the strongest specialist option for an organization that is willing to manage adoption and verify the exact plan and deployment configuration.

5. Jitsi Meet — best for no-account and self-hosted meetings

Security model

Jitsi Meet is open source and the public meet.jit.si service can be used without an account. Ordinary meetings use encrypted network transport, but the Jitsi Videobridge can access media while routing it unless E2EE is enabled. That distinction is essential: a public Jitsi room is not automatically provider-blind just because the connection uses HTTPS or encrypted transport.

Jitsi supports optional E2EE in compatible Chromium-based browsers—including Chrome, Edge, Brave, and Opera—and in its Electron client. Participants must use compatible clients and enter the same password or passphrase for the E2EE session. Jitsi’s E2EE documentation should be consulted before relying on the mode for a critical meeting.

How to enable Jitsi E2EE

1. Open a Jitsi meeting.
2. Open the overflow menu.
3. Select End-to-End Encryption.
4. Give every participant the same passphrase through a separate trusted channel.
5. Confirm that every participant is using a supported client before discussing sensitive information.

Test the exact combination of browser, mobile participant, screen sharing, moderation, recording, and other required features first. E2EE can reduce compatibility and may not work identically across clients.

Room and self-hosting risks

A public room name can be guessed, copied, or shared. Use a long, unpredictable room name and a room password, and do not publish the link in a public channel. Self-hosting changes who operates the server, but it does not automatically protect devices or participants. The operator remains responsible for TLS, updates, authentication, logs, backups, abuse handling, DDoS protection, monitoring, and link distribution. Jitsi outlines relevant deployment considerations in its security documentation.

Best for

No-account meetings, open-source deployments, technically capable organizers, and organizations that want to operate their own meeting service.

Avoid if

You need guaranteed uniform support across every browser and phone, a mature compliance-recording workflow, or a meeting where the organizer cannot test E2EE and access controls in advance.

Verdict

Jitsi is the best flexible no-account or self-hosted choice, but only when the organizer knows whether the meeting is using ordinary transport encryption or actual E2EE.

6. Zoom — best general-purpose managed meeting platform

Security model

Zoom’s ordinary meeting encryption and its optional E2EE mode have different trust models. In ordinary meetings, Zoom manages the encryption keys used by the service. Zoom also offers optional E2EE, which changes the provider’s ability to access meeting content. The difference is documented in Zoom’s E2EE documentation.

Limits and E2EE trade-offs

Basic and Pro meetings normally support up to 100 participants, and Basic meetings are limited to 40 minutes. Zoom E2EE meetings can support up to 1,000 participants, subject to the account and meeting configuration. See Zoom’s participant-limit documentation and verify the current plan.

Zoom E2EE requires the desktop app, mobile app, or Zoom Rooms. It does not support the Zoom Web App, telephone, SIP, or H.323 endpoints. If even one required participant must join through a browser or dial in by phone, the host may need to use ordinary encryption instead.

When E2EE is enabled, Zoom disables or limits important functions, including:

• Cloud recording
• AI Companion
• Continuous meeting chat
• Live streaming
• Live transcription
• Polling and surveys
• Zoom Apps
• Notes and Whiteboard

Free-account hosts can use E2EE after Zoom’s required verification process. Before a sensitive meeting, confirm the secure mode in the meeting and make sure the necessary recording, transcription, AI, phone, and browser features are not required.

Practical configuration

1. Sign in to the Zoom web portal.
2. Open the relevant meeting or account security settings.
3. Enable End-to-end encryption.
4. Confirm that every participant uses a supported Zoom client.
5. Use a passcode, waiting room, authenticated-user restriction, and meeting lock where appropriate.
6. Disable recording and content-processing features when they are not needed.

Best for

Large feature-rich meetings, webinars, external guests, moderation, screen sharing, and organizations that value interoperability and administrative controls.

Avoid if

You require provider-blind protection while also needing browser or telephone participation, cloud recording, live transcription, AI Companion, or Zoom’s full collaboration feature set.

Verdict

Zoom is a secure managed platform when configured carefully, but do not call ordinary Zoom meetings E2EE. Its E2EE mode is a deliberate high-confidentiality option with substantial compatibility and feature costs.

7. Microsoft Teams — best for Microsoft 365 organizations

Security model

Teams meetings are encrypted in transit and at rest by default. Eligible organizations can enable E2EE meetings with Teams Premium. Teams documents the requirements and limitations in its E2EE meeting guide.

Teams E2EE supports current desktop clients, iOS, Android, and Teams Rooms on Windows or Android. It does not support web, VDI, or Cloud Video Interoperability participants, and E2EE meetings are limited to 200 participants. Services that need access to meeting content, such as transcription, are unavailable in the secure mode.

Access controls and administration

Teams is particularly strong when the organization already manages identities, devices, guest access, and retention through Microsoft 365. Administrators can control who bypasses the lobby, whether anonymous users can join, whether anonymous users or dial-in callers can start a meeting, and whether unverified participants must complete a verification check.

For organizations using the available Teams policy, Microsoft gives this example for CAPTCHA verification:

Set-CsTeamsMeetingPolicy -Identity <policy name> -CaptchaVerificationForMeetingJoin AnonymousUsersAndUntrustedOrganizations

Policy names and available settings can change, so verify the command against the current Teams join-verification documentation.

Teams Free supports up to 100 participants for 60 minutes, while Microsoft 365 consumer and business plans have different limits. Do not use the Free limit as a description of every Teams account.

Best for

Organizations already standardized on Microsoft 365 that need identity management, lobby policy, tenant administration, compliance workflows, and collaboration features.

Avoid if

You need every participant to join through a browser, VDI, CVI room, or telephone while preserving E2EE, or if you require transcription and other server-side processing in the same meeting.

Verdict

Teams is often the most practical secure business choice for a Microsoft 365 tenant, but ordinary Teams encryption is not the same as E2EE. Treat Premium E2EE as a specialized mode, not a default property of the platform.

8. Google Meet — best browser-first choice for Google organizations

Security model

Google Meet meetings are encrypted in transit by default, and recordings stored in Google Drive are encrypted at rest. Google distinguishes ordinary cloud encryption from several stronger or different modes: legacy end-to-end encrypted calls, personal-account Additional encryption, and Workspace client-side encryption. These options are not interchangeable. Google describes the categories in its Meet encryption documentation.

Personal Meet calls can use Additional encryption. Business and education accounts do not use the same personal-account toggle and instead rely on the encryption options available to their Workspace configuration. Workspace client-side encrypted meetings require invited participants and identity-provider authentication, which reduces compatibility but gives the organization more control over keys.

Feature and access trade-offs

Meet’s Additional encryption mode disables features including in-call messages, reactions, polls, Q&A, add-ons, and abuse reporting. Client-side encryption can also conflict with recording, transcripts, or other collaborative services. Consumer Meet meetings support up to 100 participants; Workspace limits vary by edition.

For ordinary meetings, use Host controls to select an appropriate access mode such as Open or Trusted, require external participants to request admission when appropriate, and restrict screen sharing, chat, audio, or video. Google explains these controls in its Meet security and admission guide.

For Workspace client-side encryption, schedule the meeting in Google Calendar or start an instant meeting, choose the encryption option available to the account, and confirm that every participant is invited and can authenticate through the required identity provider. See Google’s client-side encryption overview.

Best for

Google Workspace organizations, browser-first meetings, classrooms, and groups that need low-friction joining plus strong host and tenant controls.

Avoid if

You need every ordinary meeting to be provider-blind E2EE, or if your meeting depends on reactions, Q&A, add-ons, transcripts, or recording while using a stronger client-side or Additional encryption mode.

Verdict

Meet is a strong managed platform, especially inside Google Workspace, but the default cloud-encrypted meeting should not be advertised as E2EE.

9. Cisco Webex — best enterprise option when Zero-Trust E2EE is available

Security model

Webex has several encryption models that must be separated:

• Ordinary Webex encryption protects data in transit and at rest but is not automatically provider-blind.
• Webex End-to-End Encryption uses the Webex Key Management System.
• Zero-Trust End-to-End Encryption creates a common meeting encryption key for participants using MLS and is the mode to investigate when preventing Cisco cloud access to meeting content is the primary goal.

Cisco’s Webex encryption documentation says its KMS-based E2EE can remain accessible to cloud services for functions such as indexing, data-loss prevention, file transcoding, eDiscovery, and archiving. Therefore, do not treat every Webex E2EE label as equivalent to Zero-Trust E2EE.

Access controls and limitations

Webex provides passwords, lobbies, automatic locking, authentication, and host admission. Scheduled meetings can be configured to lock automatically after 0, 5, 10, 15, or 20 minutes; the default is commonly 10 minutes, depending on the site configuration. Review Webex lobby and lock settings and Webex password enforcement.

E2EE modes can conflict with server-side features. Breakout sessions, for example, are not supported in Webex E2EE meetings. Recording, moderation, compliance archiving, and other functions must be tested against the selected mode and Webex plan.

Personal Rooms are convenient but should receive more cautious treatment than scheduled meetings when security is the priority. Use a scheduled meeting, a strong password, a lobby, authentication, and automatic locking for sensitive business discussions.

Best for

Regulated or high-control organizations that can validate their Webex plan, configure identity and policy controls, and use Zero-Trust E2EE where its feature limitations are acceptable.

Avoid if

You need a simple personal calling app, broad free consumer access, or collaboration features that are incompatible with the selected E2EE mode.

Verdict

Webex is a leading enterprise candidate when Zero-Trust E2EE, identity assurance, and administrative policy are configured deliberately. The product name alone does not tell you which encryption trust model is active.

Which app should you choose?

Situation	Recommended choice	Why	Important qualification
Sensitive personal call	Signal	E2EE calls, identity-verification tools, phone-number privacy controls, and a 75-person group limit	Everyone must use Signal, and devices and identities still need protection
Apple-only family or team	FaceTime	E2EE with very low setup friction for Apple users	Web guests have fewer features and Apple retains limited usage metadata
Cross-platform personal group	WhatsApp	Strong default call-content protection and broad adoption	Review phone-number exposure, backups, metadata, linked devices, and account takeover risks
No-account meeting	Jitsi Meet	Public meet.jit.si can be used without an account	Use a strong room name and password; enable E2EE only after checking client compatibility
Self-hosted meeting	Jitsi Meet or Wire	Both can offer deployment control; Wire is more business-oriented	Self-hosting transfers patching, logging, authentication, backups, and availability responsibilities to you
Microsoft 365 organization	Teams	Tenant identity, lobby, guest, device, and policy integration	Teams Premium is required for E2EE, which excludes web, VDI, CVI, and content-processing features
Google Workspace organization	Google Meet	Browser-first access and Workspace administration	Ordinary meetings use cloud encryption; client-side encryption has invitation and compatibility requirements
Managed enterprise or regulated deployment	Webex Zero-Trust E2EE, Wire, Teams, or Meet CSE	Choose based on identity, key control, residency, administration, and compliance requirements	Verify the actual plan and mode; E2EE may disable recording, breakout rooms, transcripts, or archiving
Large, feature-heavy external meeting	Zoom, Teams, Meet, or Webex	Strong access controls, moderation, browser support, and collaboration features	These benefits often require the standard provider-mediated encryption mode rather than E2EE

How to secure any video-call platform

1. Update everything. Install the latest app, browser, and operating-system updates before a sensitive call.
2. Protect the account. Use a unique password and enable MFA, two-step verification, registration lock, or the strongest equivalent available.
3. Create a new meeting. Avoid reusing a permanent room or old meeting ID for confidential discussions.
4. Use an unpredictable room name and a strong passcode. Never rely on a short or publicly visible room name.
5. Enable a waiting room or lobby. Admit only people you expect, and use authenticated-user or organization restrictions when practical.
6. Disable join-before-host. Otherwise a participant may enter and speak before the organizer can verify the meeting.
7. Restrict screen sharing. Allow only the host or approved presenters to share.
8. Turn off unnecessary data creation. Disable recording, transcription, AI summaries, cloud storage, automatic notes, and chat exports when they are not needed.
9. Avoid phone dial-in when E2EE is required. Telephone endpoints often cannot participate in the same cryptographic mode as app clients.
10. Verify identities out of band. Use Signal safety numbers, Wire device verification, an organization identity, or a separate trusted channel. A name displayed in a meeting is not proof of identity.
11. Review active sessions. Remove unknown linked devices and sign out old browsers.
12. Secure the physical room. Use headphones where appropriate, check who can hear the conversation, cover cameras when not needed, and prevent shoulder surfing.
13. Set a recording rule. Tell participants whether recording is prohibited, permitted, or controlled by the host, and explain where any recording or transcript will be stored.

Important trade-offs and failure modes

E2EE does not protect against participants

A malicious or compromised participant can record the screen, photograph the display, use a second phone to record the room, copy chat, or repeat sensitive information. E2EE protects the channel between endpoints and the service trust boundary; it does not create a human trust boundary.

E2EE does not protect compromised devices

Malware can capture microphone audio and camera frames before encryption, or capture decrypted audio, video, screenshots, and transcripts after they arrive. Device updates, account security, browser security, disk encryption, and physical privacy remain essential.

A lobby is not encryption

A waiting room controls who enters; it does not make media E2EE. Conversely, an E2EE call with a weak or publicly shared meeting link can still reveal information to the wrong person if that person is admitted.

Recordings create a new security boundary

A call may be E2EE while its later recording, transcript, AI summary, chat export, or screen capture is not protected by the same model. Identify the destination before recording: a local device, provider cloud, Google Drive, Microsoft or SharePoint storage, Webex storage, or a participant-controlled device all create different access and retention risks.

Browser support can silently downgrade security

A participant who cannot install the required app may force the host to use standard encryption instead of E2EE. This applies explicitly to Zoom and Teams, and compatible-browser requirements also matter for Jitsi E2EE. FaceTime web participants and WhatsApp Web callers may have a different feature set from native-app users. Check the security state shown inside the meeting rather than inferring it from the brand name.

Phone dial-in is a separate trust path

Telephone participants generally cannot receive the same E2EE guarantees as app participants. Zoom explicitly excludes telephone, SIP, and H.323 endpoints from E2EE meetings. Treat any dial-in requirement as a reason to re-evaluate the meeting’s confidentiality model.

Self-hosting is not automatically safer

Self-hosting Jitsi or Wire can reduce dependence on a public provider, but it transfers responsibility for server patching, TLS configuration, authentication, logs, backups, abuse handling, DDoS protection, monitoring, key management, and meeting-link distribution. A poorly maintained private server can be less safe than a well-managed public service.

Metadata may matter more than content

For journalists, activists, executives, and people under surveillance, the fact that two people communicated can itself be sensitive. Compare phone-number exposure, contact discovery, IP addresses, account-registration data, call timing, participant lists, device identifiers, retention periods, advertising or cross-service use, transparency reporting, and law-enforcement processes—not only whether the audio and video are encrypted.

Organization policy can defeat a product feature

A platform may technically support E2EE but have it disabled or made impractical by a tenant policy, plan, client version, compliance recording, cloud recording, transcription, AI feature, dial-in requirement, or third-party room system. Test the actual account and meeting workflow, not merely the vendor’s feature list.

A transparent way to compare security

Do not assign one unexplained numerical security score. Score each service separately against the needs of the call:

• Live-media confidentiality: Is E2EE on by default, optional, unavailable, or limited to certain clients? Can the server decrypt media while routing it?
• Identity assurance: Are accounts, devices, safety numbers, fingerprints, email addresses, phone numbers, CAPTCHA checks, or organization identities verified?
• Meeting access: Are there random identifiers, passwords, lobbies, automatic locks, anonymous-user policies, admission controls, participant removal, and screen-sharing restrictions?
• Metadata and privacy: What phone numbers, IP addresses, device data, contact information, call history, or account data are exposed or retained?
• Feature trade-offs: Does the secure mode remove recording, transcription, AI, captions, screen sharing, polls, Q&A, dial-in, browser joining, breakout rooms, or abuse reporting?
• Operational control: Are clients open source or auditable? Can the service be self-hosted or deployed on premises? Are customer-managed keys, data residency, and administrative policies available?
• Usability: Is an account or app required? Can nontechnical guests join? What happens when one participant cannot use the secure client? What are the free-tier and participant limits?

Frequently Asked Questions

Is Zoom end-to-end encrypted?

Zoom supports optional E2EE, but ordinary Zoom meetings are not automatically E2EE. Zoom E2EE requires supported desktop, mobile, or Rooms clients and excludes the web app, telephone, SIP, and H.323 endpoints. It also disables features such as cloud recording, live transcription, AI Companion, polling, and live streaming. See Zoom’s E2EE documentation.

Is Google Meet end-to-end encrypted?

Not every Meet call. Ordinary Meet meetings are cloud-encrypted, and recordings in Google Drive are encrypted at rest. Personal accounts may have an Additional encryption mode, while Workspace customers may have client-side encryption. Those stronger modes have different eligibility and feature limitations, so an ordinary Meet meeting should not be described as provider-blind E2EE.

Is Microsoft Teams end-to-end encrypted?

Teams meetings are encrypted in transit and at rest by default. E2EE is an additional feature for eligible Teams Premium meetings. Teams E2EE is limited to 200 participants and does not support web, VDI, or CVI clients or services such as transcription that need access to meeting content.

Is WhatsApp safer than Zoom?

For personal call content against provider access, WhatsApp’s personal calls are E2EE by default, while ordinary Zoom meetings use a different provider-mediated encryption model. Zoom may be safer for meeting admission, moderation, enterprise administration, and large external events. The answer depends on whether your main threat is provider access to content, an uninvited participant, account takeover, metadata collection, or endpoint compromise.

Is FaceTime safer than Signal?

Both provide E2EE call content. FaceTime is usually the easier choice for an Apple-only group and supports up to 32 participants. Signal provides stronger-purpose privacy controls such as safety-number verification, phone-number visibility settings, usernames, and registration lock. Neither service makes users anonymous or prevents participants from recording a call.

Can a video-call company see or record my calls?

It depends on the product mode and features. In provider-blind E2EE modes, the service is designed not to possess the keys needed to decrypt live media, although endpoints and participants can still record it. Standard managed-meeting modes may allow provider services to process content for routing, transcription, recording, moderation, search, compliance, or AI features. Check where recordings and transcripts are stored and who controls them.

Does a waiting room make a meeting private?

No. A waiting room or lobby controls admission; it does not encrypt the meeting. Use it together with a unique meeting ID, strong passcode, host admission, authenticated users where appropriate, and restricted screen sharing.

Are browser calls as secure as app calls?

Not necessarily. A browser may lack a platform’s E2EE mode or advanced identity controls. Zoom E2EE excludes its web app, Teams E2EE excludes web clients, and Jitsi E2EE currently depends on compatible Chromium-based browsers or its Electron client. FaceTime web participants also have fewer features. Confirm the active security mode and client requirements before the call.

Does end-to-end encryption prevent screenshots or recordings?

No. E2EE protects the communication path and the provider trust boundary. An admitted participant can use built-in recording, screen capture, another phone, a camera, or a microphone to preserve or redistribute the conversation.

Which app is best for journalists or activists?

Signal is the best default for sensitive personal calls when all participants can use it and verify one another. It is not an anonymity tool: phone-number registration, metadata, compromised endpoints, physical surveillance, and participant trust still matter. High-risk users should also consider device security, separate identities, network exposure, and operational practices beyond the calling app.

Which app is best for business compliance or regulated meetings?

There is no universal winner. Webex Zero-Trust E2EE, Wire, Teams with the appropriate Microsoft 365 controls, or Google Meet client-side encryption may fit depending on identity, key management, data residency, retention, recording, and audit requirements. E2EE can conflict with compliance recording, transcription, breakout rooms, and eDiscovery, so involve the organization’s security and legal teams before selecting a mode.

What is the safest free video-call app?

For private app-to-app calls, Signal is the strongest general answer. Jitsi Meet is useful for no-account meetings and can provide E2EE when all participants use compatible clients, while FaceTime is excellent for Apple-only groups and WhatsApp is practical across platforms. Free plans and features change, so choose based on the participants and threat model rather than price alone.

Does self-hosting make Jitsi secure?

Self-hosting gives the organizer more control over the server and data, but it does not automatically make a meeting secure. The operator must maintain the server, authentication, TLS, logs, backups, monitoring, availability, and meeting links. Enable Jitsi E2EE when appropriate and ensure every participant uses a compatible client; self-hosting does not protect compromised endpoints.

What happens when someone joins by phone?

Phone participants may not support the same E2EE guarantees as app participants. Zoom explicitly excludes telephone, SIP, and H.323 endpoints from E2EE meetings. If confidentiality is more important than accessibility, require supported app clients and disable dial-in; otherwise document that the meeting uses a weaker or different trust model.

The Bottom Line

Choose the app that matches the threat model, not the one with the strongest-sounding marketing. Use Signal for sensitive personal calls, FaceTime for Apple-only groups, WhatsApp for broad personal adoption, Jitsi for no-account or self-hosted meetings, and Wire for security-focused organizations. Use Zoom, Teams, Meet, or Webex when administration, interoperability, moderation, recording, and compliance matter—but explicitly decide whether those features justify using standard provider-mediated encryption instead of a more restrictive E2EE or client-side-encryption mode.
