Proton VPN Free is a VPN service that was launched in 2017. It's owned and operated by Proton AG, a Swiss company that also operates Proton Mail, an encrypted email service. It's the free version of Proton VPN, which we tested separately. Compared to the paid version, it lacks some key functionalities, like the ability to select which country's servers to connect to and the ability to download torrents. See the rest of their differences in the Differences Between Variants section.
Our Verdict
While Proton VPN Free has no data limits, downloading torrents and P2P files is reserved for the paid Plus version. Also, download speeds are throttled compared to the Plus version.
Kill switch works properly.
Doesn't leak your IP address or DNS queries.
Proper TLS implementation doesn't leave you vulnerable to man-in-the-middle attacks.
Can't download torrents.
Proton VPN Free is good for private browsing. The service has excellent security that effectively protects your IP address and DNS queries. Beyond that, its policies and company practices are just acceptable. Its policies aren't written in a way that's easy to understand for everyone, and specify that they collect more of your personal information than is absolutely necessary for the service to function. They also employ aggressive marketing tactics that encourage you to stay subscribed for as long as possible.

Jargon-filled policies are difficult to understand.
Proton VPN Free has passable policies and business practices. Its privacy policies and terms of service are not written in a way that's easy for anyone to understand, and allow the company to collect more of your information than necessary for the service to function. Proton publishes frequent third-party security and policy audits that return positive results, but the latter's scope is somewhat limited. Proton generally conducts itself in a way that instills trust, but a few scattered incidents, mostly pertaining to other services under the parent company's umbrella, are enough to raise an eyebrow.

Jargon-filled policies are difficult to understand.
Proton VPN Free has excellent security. It keeps your IP address or DNS queries anonymous while you're connected to it, and it has proper TLS implementation, protecting you from man-in-the-middle attacks. Additionally, its kill switch works as intended, blocking unencrypted data from leaking from your system in case of a reboot or reconnecting after a loss of internet connection.

Popular VPN Comparisons
Proton VPN Free is good for browsing the web privately, but it lacks some important functionality that puts it behind other free VPNs. While it has no data limits, it doesn't allow you to download torrent files, as that feature is reserved for the paid version. Additionally, you can't manually select the country you want to connect to; instead, it automatically connects to the fastest server, which is usually the closest, rendering it ineffective for bypassing georestrictions. Its speeds are throttled compared to the paid version, but that's par for the course for free VPNs.
On the plus side, Proton VPN Free has generally acceptable privacy policies and business practices, which make it much more trustworthy than the numerous unproven free VPNs on the market. That said, its privacy policies are difficult to understand if you're not familiar with the legal jargon it uses, and the company employs some tactics that aren't the most consumer-friendly.

Test Results
Like most VPN providers, Proton VPN Free doesn't secure its internet routing (BGP) properly. This means that even if your ISP protects against attacks like route hijacking, your traffic could still be misdirected once it enters Proton's network. This is only a concern for highly targeted and resource-intensive attacks that are feasible only for governments or large corporations to orchestrate.
Note that Proton VPN Free's privacy policy is a sub-policy of Proton AG's (the parent company) privacy policy that applies when you create a Proton account, which is mandatory to use the VPN service.
While a no-logs policy that specifies Proton doesn't log your traffic or IP address while connected to the VPN, there are several instances in the privacy policy that claim to record your IP address for various, sometimes vague purposes and for unspecified periods of time.
Proton commissions clear and detailed third-party audits yearly, but the scope is limited to the no-logs policy and not the wider privacy policies.
Proton VPN Free's company practices are just okay. The terms of service can be difficult to understand if you're not familiar with the legal jargon that's used to write them. They also lack information about data retention, disallow class action lawsuits, and require arbitration instead of going to trial in public courts, demonstrating a lack of confidence in their ability to publicly settle disputes with users.
Proton also engages in pushy marketing practices, such as offering large discounts to the paid version exclusively to new subscribers, encouraging the use of their other apps, and sending marketing emails. These practices don't make the service worse, but they indicate where the company's priorities are.
Otherwise, Proton is generally communicative and transparent with its users about the service, but there have been incidents in the past where executives haven't rigorously upheld the company's policy of political neutrality.
Proton VPN Free offers fast and consistent download speeds, making it suitable for regular internet use and quick file downloads.
Its speeds are throttled compared to the paid version of Proton VPN. You can compare speed results between the two services.
This VPN delivers upload speeds suitable for everyday internet use and uploading large files relatively quickly.
Its speeds are throttled compared to the paid version of Proton VPN. You can compare speed results between the two services.
This VPN has bad latency performance that's worse than other VPNs. It's not suitable for latency-sensitive applications, such as online gaming, and can lead to issues in video calls, as well as generally feeling slow when browsing the web.
Proton VPN Free doesn't allow you to download torrents, as this feature is reserved for the paid version.
This VPN has native Linux apps for Ubuntu, Debian, and Fedora GNOME desktop environments. Proton indicates that the app should work on most derivative distributions, despite not being officially supported. You can also manually configure OpenVPN or WireGuard on Linux.
Stealth is a proprietary protocol that utilizes obfuscation to disguise your VPN traffic as HTTPS traffic. This is useful if you're dealing with internet censors that block access to a site through a VPN.
While it has servers in five countries, Proton VPN Free automatically connects you to the server it deems fastest, so you can't manually choose which country to connect to. That said, if you configure a headless setup, you can choose which country to connect to by downloading the appropriate .conf or .ovpn file.
