About Proton VPN

Proton VPN Download, Secure, No-Logs VPN Service

TL;DR Quick Take / Who is this for?

Proton VPN is the privacy-focused VPN from the Swiss company behind Proton Mail, and it has earned a reputation as the best free VPN available, not because it is the most powerful, but because it is the only one that does not impose a data cap, show ads, or sell your activity. The free plan gives you unlimited data, servers in 10 countries, one device connection, and the same audited no-logs policy that covers paying customers. The paid VPN Plus plan expands that to over 20,000 servers in 140+ countries, up to 10 simultaneous connections, Secure Core multi-hop routing, NetShield ad and malware blocking, P2P support, and streaming unblocking for 10 of 14 tested services. The service is independently audited every year, its apps are open source, and it operates under Swiss privacy law. The trade-offs are real. Speeds are uneven, the free plan does not let you choose a server or use it for streaming, and customer support is a recurring source of frustration. Trustpilot rates Proton VPN 2.2 out of 5, with complaints about billing, connection reliability, and unresponsive support. Proton VPN is the right pick for privacy-conscious users, journalists, activists, and anyone who wants a genuinely usable free VPN without data limits. It is not the best choice for users who prioritise consistently fast speeds for gaming or heavy streaming, or who expect responsive human support when something goes wrong.

Quick Info Box

Key Features & Real-World Usability

Proton VPN’s defining feature is its privacy architecture. The company operates under Swiss jurisdiction, publishes annual no-logs audits conducted by independent firms, and releases its applications as open source so anyone can inspect the code for vulnerabilities or backdoors. Secure Core, available on paid plans, routes your traffic through multiple servers in hardened, physically secured locations before it exits to the internet, which makes it significantly harder to correlate your activity with your real IP address. The free plan is genuinely unusual. It does not throttle your speed, it does not impose a data cap, it does not show ads, and it applies the same no-logs policy as the paid tiers. The limitation is server access: you get servers in 10 countries, but you cannot choose which one, and the free plan is not intended for streaming or torrenting. The paid VPN Plus tier removes those restrictions. It unlocks over 20,000 servers across 140+ countries, up to 10 simultaneous connections, NetShield ad and malware blocking, Secure Core routing, P2P support with port forwarding, and split tunnelling. In independent testing, Proton VPN unblocked 10 of 14 streaming services and lost an average of 10.2% download speed across three server locations, numbers that place it in the same performance tier as NordVPN and ExpressVPN, though its speeds are described as uneven rather than consistently the fastest. The client interface is functional and accessible, though some reviewers note that certain apps, particularly on macOS, feel less polished than competitors. Advanced privacy features include discreet app icons that can disguise the VPN as a calculator or weather app, and Stealth protocol support on every plan for bypassing VPN blocking.

• Audited no-logs policy: Independently audited every year for five consecutive years, with reports published publicly, and the same policy applies to free and paid users alike.
• Secure Core multi-hop routing: Routes traffic through hardened servers in privacy-friendly jurisdictions before exiting to the internet, available on paid plans with 125 Secure Core servers.
• Free plan with unlimited data: No data cap, no ads, no speed throttling, and no time limit, features that almost no other free VPN offers.
• Large paid server network: Over 20,000 servers in 140+ countries on VPN Plus, with up to 10 simultaneous device connections.
• NetShield ad and malware blocking: DNS-level filtering that blocks ads, trackers, and malicious domains on paid plans, reducing reliance on browser extensions.
• Open-source applications: All client apps are open source, allowing independent security researchers to audit the code and verify privacy claims.
• Swiss jurisdiction: Operates under Swiss privacy laws, which are among the strongest in the world for protecting user data from foreign surveillance requests.
• Broad platform coverage: Native apps for Windows, macOS, Linux, Android, iOS, Android TV, Apple TV, Fire TV, and browser extensions for Chrome and Firefox.
• Stealth protocol on every plan: Obfuscation technology that helps bypass VPN blocking in restrictive networks, available to free and paid users.

Pros, Cons & Community/User Feedback

Expert reviews of Proton VPN are consistently glowing, while user reviews on Trustpilot tell a sharply different story. CNET awards Proton VPN an 8.0 out of 10 and calls it the best free VPN on the market, praising its “exceptional privacy and transparency,” open-source apps, large server roster, and excellent value, while noting that “uneven internet speed loss” and some less user-friendly apps are the main drawbacks. Gizmodo gives it a 4.6 and ranks it as the number two VPN overall, highlighting Secure Core servers, the audited no-log policy, Swiss jurisdiction, the free plan with no data cap, and port forwarding as strengths, and listing the absence of Smart DNS, the lack of post-quantum encryption, and pro-rata refunds as weaknesses. PCMag goes further, awarding Proton VPN a five-star rating and an Editors’ Choice award, and stating that it “provides unmatched privacy, value, and features, with the industry’s best free plan and an exceptional premium experience.” Those expert assessments are consistent: Proton VPN is technically excellent, transparently run, and unusually generous on the free tier. User sentiment on Trustpilot is a different picture entirely. The service is rated 2.2 out of 5, with reviewers describing it as “scammers,” reporting that the VPN “takes far too long to connect” or does not connect at all, and complaining that support is unresponsive or automated. One reviewer reported being charged after a signup that did not complete, with no way to log in or contact support. Another described deleting a Proton Mail account and discovering that it also deleted their VPN account, with support failing to respond for days. A GitHub issue also flagged a leak in the Smart Routing technology that exposed real server locations for an estimated 6.7 million users in Latin America. The practical takeaway is that Proton VPN’s engineering, privacy architecture, and free tier are genuinely best-in-class, while its connection reliability, billing processes, and customer support are the areas where users consistently report frustration. The gap between expert praise and user complaints is wider for Proton VPN than for almost any other VPN, and that gap matters when you are deciding whether to trust the service with your traffic.

Final Verdict & Safe Download Advice

Proton VPN is the VPN to choose if privacy is your first priority and you want a free tier that is genuinely usable rather than a crippled demo. The audited no-logs policy, Swiss jurisdiction, open-source code, and Secure Core routing put it in a different category from VPNs that treat privacy as a marketing slogan. The free plan is the best in the industry, full stop, and the paid VPN Plus tier is competitively priced while adding the features, server choice, streaming, P2P, NetShield, that most users eventually want. The caveats are significant enough to change the decision for some buyers. Speeds are uneven, support is unreliable, and the Trustpilot complaints about billing and connection failures are not isolated incidents. If you need a VPN for competitive gaming, heavy streaming across multiple devices, or you expect responsive human support, another provider may serve you better. If you want strong privacy protections, a free tier that does not treat you as a product, and a company that publishes audits rather than promises, Proton VPN is the most trustworthy option available, provided you go in with realistic expectations about performance variability and support quality.

• Download only from protonvpn.com: The official site distributes the installers directly. Third-party “Proton VPN free download” pages and software portals may repackage the installer with unwanted software or outdated builds.
• Verify the installer size and version: The Windows installer is approximately 124 MB, and the current version is 5.1.8. A dramatically smaller file or an older version number is a warning sign.
• Check system requirements before installing: Proton VPN requires Windows 10 or later, macOS 12 or later, or a modern Linux distribution. The mobile apps require Android 8+ or iOS 15+.
• Understand the free plan limits before signing up: The free plan offers unlimited data and servers in 10 countries, but you cannot choose a specific server, you can connect only one device at a time, and the plan is not intended for streaming or torrenting. If you need those features, the paid VPN Plus tier is required.
• Enable Secure Core if you are on a paid plan: Secure Core routes traffic through multiple hardened servers, significantly improving privacy at the cost of some speed. It is worth enabling for sensitive sessions even if you disable it for everyday browsing.
• Keep your recovery methods secure: Proton accounts can be tied to Proton Mail, and deleting one service may affect the other. Ensure your recovery email and password are stored safely, and be aware of the account-linking behaviour described in user complaints.
