Choose a VPN by verifying four things before you install it: what traffic it actually encrypts, what permissions the app requests, what its privacy policy says it collects or shares, and what independent evidence supports its claims. A VPN can reduce what an open Wi‑Fi operator can read, but it does not make you anonymous. The VPN provider becomes another party you must trust. For ordinary browsing, the Federal Trade Commission (FTC) says public Wi‑Fi is usually safe because encryption is now widespread, so a VPN should supplement—not replace—HTTPS, strong account security, and current software.
What a VPN changes when you browse
A VPN app creates an encrypted connection from your device to servers operated by the VPN provider, then routes your internet traffic through that connection. To a website, the connection can appear to originate from the provider’s server rather than directly from the coffee-shop, hotel, airport, or library network you joined.
That arrangement changes who can observe parts of the connection. Someone operating the local Wi‑Fi network may be unable to read the contents carried inside the VPN tunnel. The provider, however, becomes a new intermediary that may be able to observe connection information and, depending on the service’s design and policies, other traffic details. Selecting a VPN is therefore a trust decision, not simply a search for the fastest app.
What the local network may see
Without a VPN, the hotspot operator can observe connection information such as the device’s participation on the network and the destinations it can infer from network activity. HTTPS still protects the contents exchanged with an HTTPS website. With a VPN, the local operator generally sees an encrypted connection to the VPN service rather than each destination connection inside that tunnel.

What the VPN does not hide
A VPN does not erase information you give to websites. If you sign in, submit an email address, upload a file, or identify yourself in a form, the destination can associate that activity with your account or the information you supplied. Browser cookies, device settings, and account activity can also allow a site to recognize you. The FTC summarized the limitation in its VPN-app guidance: “A VPN app generally isn’t going to make you entirely anonymous.”
Why encryption is not a trust seal
A VPN can protect a connection in transit without making either the VPN operator or the destination website honest. A fraudulent website can use HTTPS, and a VPN provider can make broad security or “no logs” claims that are not independently established. Treat encryption, site legitimacy, and provider trust as separate questions.
Do you need a VPN on public Wi‑Fi?
Not automatically. In February 2023 consumer guidance, the FTC said connecting through public Wi‑Fi is usually safe because encryption is widespread. That assessment means a VPN is not a prerequisite for ordinary web use when you use HTTPS and maintain normal account and device security.
Recommended Free Tools
A VPN can still be useful when you want to reduce the local network’s visibility into your connection, when you do not control the hotspot, or when your own risk assessment calls for an additional encrypted layer. It cannot compensate for joining the wrong network, visiting a scam site, reusing passwords, or running unpatched software.
Public-network risks that remain without or with a VPN
- Impostor hotspots: An attacker can create a network name resembling the venue’s name. Confirm the exact network name and sign-in procedure with staff before connecting.
- Unencrypted or misleading sites: Look for HTTPS, but remember that HTTPS does not prove the site is legitimate.
- Account takeover: Strong, unique passwords and two-factor authentication reduce the damage if a password is exposed elsewhere.
- Outdated software: Keep the operating system, browser, phone software, and security tools current; a VPN does not repair known device vulnerabilities.
What to look for in a VPN
Evaluate the provider and the app with the same questions you would use for any security service. Marketing language is a starting point, not proof.

1. Encryption and traffic coverage
Confirm that the app encrypts the connection and determine exactly what it covers. Some VPN apps protect all traffic from the device; others protect only selected applications or traffic types. A service that protects a browser but leaves another app outside the tunnel may not meet your public-Wi‑Fi goal.
Read the provider’s technical explanation for exclusions such as split tunneling, manually selected apps, or traffic that the operating system handles outside the VPN. Check whether the app clearly indicates when the tunnel is connected and what happens if it drops. If the documentation never states what is encrypted, treat that uncertainty as a selection failure rather than assuming full coverage.
2. Privacy policy and data sharing
Read the current privacy policy and terms before creating an account or paying. Look for the categories of information collected, how long they are retained, the reasons for collection, and whether information is shared with advertising, analytics, affiliates, contractors, or other third parties.
Distinguish content from metadata. A policy may say it does not store browsing content while still describing collection of account details, device identifiers, timestamps, bandwidth, diagnostic data, or connection information. The policy should explain those categories in plain language and identify the legal entity responsible for the service. If the policy is vague, contradictory, or difficult to find, you cannot verify the privacy trade-off.
3. App permissions
Review every permission requested by the app on your device. A VPN needs permission to create or manage a network connection, but unrelated access—such as contacts, call history, microphone, or precise location—deserves a specific explanation. Deny permissions that are not necessary for the feature you intend to use, and do not install an app whose requested access you cannot justify.

Check the permissions again after updates. App behavior and permission requests can change, and an earlier review does not guarantee that a later version behaves the same way.
4. Independent evidence and provider reputation
Look for credible outside reviews, technical assessments, and independently verifiable evidence for the provider’s claims. Do not treat a “secure” or “no logs” statement as proof by itself. The FTC advises researching an app outside its own marketing pages and examining its terms and privacy policy.
Evidence should match the claim. An audit of a particular application or infrastructure component on a particular date does not establish that every product, server, or future version has the same properties. Note the scope, date, and any limitations before relying on it.
5. Device and operating-system support
Verify that the app supports every device you plan to protect: for example, your phone, tablet, laptop, or work computer. Confirm that the supported operating-system versions include the ones you actually run and that the app can reconnect reliably after switching between cellular data and Wi‑Fi.
Usability is a security feature. An app that is confusing to activate, hides its connection state, or regularly fails on public networks is less useful than a simpler service whose coverage you can verify.

6. Cost, renewal, and account terms
Compare the current plan terms on the provider’s own site before purchase. Check whether the displayed amount is introductory, monthly, annual, or a one-time allowance; when renewal occurs; how cancellation works; and whether the same account can cover your required devices. Prices and terms change, so do not rely on an old review or a screenshot.
A comparison worksheet you can use
Record the answers for each candidate instead of relying on a feature list. If a provider will not answer a question, mark it as unknown rather than inferring a favorable result.
| Axis | What to verify | Acceptable evidence | Warning sign |
|---|---|---|---|
| Encryption | Whether the tunnel encrypts traffic and whether coverage is device-wide or limited to selected apps | Clear technical documentation and visible connection status in the app | Only a slogan such as “military-grade” with no coverage details |
| Data handling | Collection, retention, and sharing of content, metadata, diagnostics, and account information | A current, specific privacy policy and terms | Unclear logging language or undisclosed third-party sharing |
| Permissions | Every device permission and the feature that needs it | Permission prompts that match documented functionality | Requests for unrelated personal data |
| Independent support | Whether security and privacy claims have been examined outside the provider’s marketing | Credible, scoped, dated assessments or reviews | Only self-published “no logs” claims |
| Compatibility | Support for your operating systems, devices, and network transitions | Current compatibility information and a usable app | Your device or required operating-system version is unsupported |
| Terms | Price, renewal date, cancellation, device limits, and refund conditions | Current checkout and account terms | Unclear renewal or cancellation language |
Step-by-step: choosing and setting up a VPN
- Define the risk you are addressing. Decide whether your main goal is reducing visibility on an untrusted local network, protecting selected apps, or covering all device traffic. A vague goal makes it easy to buy features you do not need while missing the coverage you do.
- List the devices and networks involved. Write down the operating systems you use and whether you will connect from hotels, cafés, airports, libraries, workspaces, or other venues. Confirm support for those systems before evaluating price.
- Read the app’s coverage documentation. Verify whether all traffic is tunneled, which traffic is excluded, and how the app signals a dropped connection. Save the relevant explanation so you can check it after an update.
- Read the privacy policy and terms. Identify collection, retention, sharing, advertising, analytics, and account requirements. Reject services whose data practices you cannot explain in your own words.
- Inspect permissions before installation and at first launch. Approve only requests that make sense for VPN operation. If an unexpected permission appears, pause and investigate instead of granting it automatically.
- Check outside evidence. Look for independent material that identifies what was examined, when, and under which conditions. Treat a narrow assessment as evidence about that scope—not a guarantee about every product or future version.
- Review the commercial terms. Confirm the recurring amount, renewal timing, cancellation process, refund conditions, and device allowance before payment. Keep a copy of the terms you accepted.
- Test the actual workflow. On a non-critical connection, install the app, connect, switch between Wi‑Fi and cellular data, and verify that the app clearly reports its state. Make sure the sites and apps you need still work before depending on the VPN while traveling.
How to use a VPN safely on public Wi‑Fi
- Verify the hotspot first. Ask venue staff for the exact network name and login steps. Do not choose a similarly named network merely because its signal is stronger.
- Join the network and complete any venue sign-in. If the sign-in page does not appear while the VPN is active, disconnect temporarily, complete the venue’s login, and reconnect immediately afterward. Do not enter sensitive credentials into a page whose address or design you cannot verify.
- Start the VPN before sensitive activity. Confirm that the app shows an active connection before opening accounts, sending work, or handling private information.
- Use HTTPS regardless of VPN status. Check the address and browser security indicator before entering passwords or payment details. HTTPS protects the connection to that site but does not validate the site’s honesty.
- Prefer strong account protection. Use a different, strong password for each important account and enable two-factor authentication where available.
- Disconnect deliberately. When leaving the venue, disconnect from the hotspot and remove or forget networks you will not use again. This reduces the chance of automatic reconnection to an untrusted network.
- Update before travel. Install operating-system, browser, phone, and security updates before relying on a public connection. A VPN cannot patch a vulnerable device.
Everyday browsing: where a VPN helps and where it adds friction
Situations where it can be useful
- Untrusted local networks: The encrypted tunnel can reduce what the hotspot operator can read about traffic inside the tunnel.
- Frequent travel: A consistent, documented connection workflow may be easier to apply across many unfamiliar networks.
- Shared environments: A VPN can add separation when you do not control the network equipment or its administration.
Trade-offs to expect
- Another trust relationship: The provider becomes an intermediary, so its collection and sharing practices matter.
- Compatibility problems: Some websites or apps may react to a provider’s shared addresses, and selected traffic may be outside the tunnel.
- Performance variation: Routing traffic through an additional server can affect responsiveness; the practical result depends on the network, provider, and server location.
- Account and permission overhead: You may need an account, recurring payment, and network permission that you would not need for ordinary HTTPS browsing.
Do not purchase a VPN solely because a site says public Wi‑Fi is always dangerous. The FTC’s “usually safe” assessment and its advice to use HTTPS mean that a VPN is an optional layer for a particular risk, not a substitute for basic security.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What a VPN cannot fix
- It cannot make a fraudulent website legitimate or detect that you are being phished.
- It cannot hide information you voluntarily submit to a website or an account provider.
- It cannot stop an account takeover caused by a reused or weak password.
- It cannot remove malware, patch an outdated operating system, or secure another device that is not using the VPN.
- It cannot guarantee that every app’s traffic is protected when the service covers only selected applications or traffic types.
- It cannot prove that a provider keeps no logs merely because its advertising uses that phrase.
Common problems and practical fixes
The app says connected, but another app is still exposed
Check the provider’s coverage documentation and the app’s per-application or split-tunnel settings. Some services intentionally exclude selected traffic. If you need device-wide coverage, choose a configuration that explicitly provides it and disable exclusions you do not require.
The public network login page will not load
Public hotspots often require a venue sign-in before normal internet access. Disconnect the VPN briefly, complete the verified venue login, and reconnect. Avoid entering credentials until you have confirmed both the network name and the page address with staff or the venue’s published instructions.

The connection drops without an obvious warning
Do not assume that a VPN protects traffic while its status is unclear. Stop sensitive activity, check the app’s connection indicator, and reconnect. Review whether the app offers a setting that blocks traffic when the tunnel is unavailable; if it does not, understand that a drop may return the device to ordinary network routing.
The provider’s privacy explanation is confusing
List the unanswered questions: what is collected, how long it is kept, who receives it, and whether advertising or analytics partners are involved. If the policy cannot answer those questions, select a service with clearer terms rather than treating ambiguity as privacy.
A permission request seems unrelated
Pause installation and compare the request with the app’s documented features. Deny the permission if the function does not need it. If the app refuses to operate without unrelated access, consider that a reason not to use it.

A final pre-install checklist
- Can you state exactly which traffic the app encrypts?
- Have you read the current privacy policy and identified collection, retention, and sharing?
- Do every requested permission and account requirement make sense?
- Is there credible, dated evidence beyond the provider’s own marketing?
- Are your devices and operating-system versions supported?
- Do you understand the recurring price, renewal date, cancellation process, and device allowance?
- Will you still verify the hotspot, use HTTPS, enable two-factor authentication, and keep software updated?
If any answer is no, the problem is not that you need more features; it is that you do not yet know what protection you are buying. Choose only after the provider’s coverage and data practices are clear, then use the VPN as one layer in a broader public-network routine.
