Yes. VPN gateways, apps, accounts, and configurations can be compromised. What that means depends on the kind of VPN: a consumer VPN routes your internet traffic through the provider’s servers, while an enterprise remote-access VPN connects you to an organization’s network. Neither makes a compromised device safe or guarantees anonymity.
What does “hacking a VPN” mean?
A VPN is not one single target. An attacker may exploit the software or appliance that runs a VPN gateway, steal an account’s credentials, compromise a device that connects to the service, or take advantage of an insecure client configuration. The consequences differ depending on whether the VPN carries personal browsing traffic or provides access to an organization’s internal network.
| VPN type | What it does | What a compromise can put at risk |
|---|---|---|
| Consumer VPN | Routes a user’s internet traffic through servers controlled by the provider. | Traffic handled by the service, account access, or privacy expectations tied to the provider. The user must trust the provider that routes the traffic. |
| Enterprise remote-access VPN | Lets an employee or other authorized user connect to an organization’s network. | The gateway, credentials, connected device, and any internal resources reachable through the granted access. |
The Federal Trade Commission explains that a consumer VPN can reduce exposure to people monitoring traffic on a local Wi-Fi network, but the provider becomes able to route that traffic. A VPN also cannot stop a website from identifying you through information you submit, and it does not secure a device that an attacker already controls. FTC: In the market for a VPN app?

Unpatched gateway software
Internet-facing VPN gateways can be targets for software vulnerabilities. In a historical example, CISA warned that CVE-2019-11510 could let an unauthenticated remote attacker compromise affected Pulse Secure servers. That advisory documents a past vulnerability; it is not a claim that the product is currently vulnerable. CISA: Continued Exploitation of Pulse Secure VPN Vulnerability

Flaws that require an account
Some vulnerabilities can be exploited only after authentication, but that does not make them harmless. NIST’s record for CVE-2025-20333 describes an authenticated remote code-execution flaw in the VPN web server of affected Cisco Secure Firewall ASA and FTD software. It says successful exploitation could enable root-level code execution and complete device compromise. This is a product- and software-specific case, not a statement about every Cisco device or VPN. Check the vendor’s current advisory and affected-version information before taking action. NIST NVD: CVE-2025-20333
Stolen credentials or a compromised device
An attacker with a legitimate user’s credentials—or control of a device that can connect—may be able to enter an enterprise remote-access environment. The damage then depends on what that account or device is allowed to reach. Least privilege and network segmentation can limit the paths available after access is gained.

Weaknesses in client configuration
A 2019 academic study examined 30 popular commercial VPN services and found configuration flaws in the setups it studied that could enable interception, encryption stripping, authentication bypass, or credential theft. That is evidence about those studied setups at that time—not a current ranking, a count of insecure services today, or a conclusion about all VPN providers. Bui, Rao, Antikainen, and Aura: Client-side Vulnerabilities in Commercial VPNs
Misconfiguration and unnecessary exposure
VPN systems can be complex to configure and maintain. Government cybersecurity guidance identifies vulnerabilities, misconfiguration, and compromised accounts or devices as risks to enterprise network access. An exposed management interface or unnecessary service can add another route for attackers to target. CISA and partners: Modern Approaches to Network Access Security

What can an attacker do after a compromise?
The impact depends on the entry point and the access it provides. NSA and CISA warn that exploiting remote-access VPN solutions can lead to credential theft, remote code execution, weakened or hijacked encrypted sessions, and access to sensitive device data. For an organization, an intruder who reaches a gateway may also be able to access internal resources permitted by the account and network design. NSA and CISA: Selecting and Hardening Remote Access VPN Solutions
For a consumer VPN, a provider-side compromise matters because the provider’s servers route the user’s traffic. A VPN changes which parties can observe traffic at different points; it does not make the user invisible to every website or guarantee that the provider cannot see or expose data. A “no logs” claim by itself does not prove that a service cannot access or disclose information.

Does a VPN protect you from hackers?
It can help protect traffic from people monitoring an untrusted local network, but it is not a general-purpose security shield. It does not prevent phishing, fix weak account passwords, block every malicious website, or undo malware already running on a device. Nor does it prevent a site from recognizing you based on details you provide or other information available to that site.
- It can help with: reducing exposure of network traffic to observers on the local connection, depending on the VPN and how it is configured.
- It cannot guarantee: anonymity, protection from a compromised endpoint, or security against a vulnerable VPN service or gateway.
- It changes: the route traffic takes and which network operators or service providers handle it.
How can individual users reduce VPN risk?
- Keep the device and VPN app updated. Install security updates for your operating system and VPN client.
- Protect the VPN account. Use a unique, strong password and enable multifactor authentication (MFA) if the service offers it.
- Choose software carefully. Avoid untrusted VPN apps, and review the provider’s privacy and security claims rather than treating any single claim as proof of safety.
- Secure the endpoint. Keep the device itself protected; a VPN cannot restore security if malware or an attacker already controls it.
A hardware security key may be useful for MFA only if the VPN account supports a compatible key. It can strengthen account authentication, but it does not prevent software exploits, provider breaches, or endpoint compromise. NSA and CISA remote-access VPN guidance

How should organizations harden remote-access VPNs?
Organizations should treat a VPN gateway as an exposed entry point and reduce both the chance of compromise and the access available if one occurs. NSA and CISA guidance recommends standards-based solutions, strong authentication, prompt patching, and reducing unnecessary attack surface. CISA and its partners also emphasize the risks of misconfiguration and overly broad network access.
- Choose standards-based products from vendors with a demonstrated vulnerability-remediation record.
- Require strong authentication, including MFA.
- Install security updates promptly and check current vendor advisories for the exact product and software version.
- Disable unnecessary features and limit exposed management and service interfaces.
- Log and monitor VPN access for suspicious activity.
- Use least privilege and network segmentation so an account or device can reach only the resources it needs.
Zero Trust, Secure Access Service Edge (SSE), and Secure Access Service Edge (SASE) are approaches organizations may consider as part of a broader network-access strategy; they are not drop-in consumer VPN products. CISA and partners: Modern Approaches to Network Access Security
How common are VPN hacks?
The sources cited here do not establish a population-wide rate for how often VPNs are hacked. The 2019 study’s sample of 30 commercial VPN services describes the scope of that study, not the prevalence of vulnerabilities across the market. It should not be used as a current security ranking or a measure of how likely a particular user is to be affected.
