In-Depth Security & Privacy Review
Privacy isn’t just a feature for Proton VPN; it’s the core of its existence. This section of our Proton VPN review will break down the multiple layers of trust and technology that make it a top choice for security-conscious users.
Swiss Jurisdiction and Proton AG’s Reputation
Proton VPN is headquartered in Geneva, Switzerland. This is a critical advantage, as Switzerland has some of the world’s most robust privacy laws and is not part of the EU or the 5/9/14 Eyes intelligence-sharing alliances. The service is operated by Proton AG, the same company behind Proton Mail, a globally respected encrypted email service. This background, rooted in scientific and privacy-advocacy communities, provides a level of credibility that few other VPN providers can claim.
Open Source and Audited No-Logs Policy
Proton VPN’s commitment to transparency is absolute. All of its applications—on Windows, macOS, iOS, Android, and Linux—are 100% open-source. This means anyone can scrutinize the code to verify that it is secure and functions as promised. Furthermore, the company enforces a strict no-logs policy that has been verified by independent third-party security audits. These audits confirm that Proton VPN does not log user traffic or any other personally identifiable metadata.
Secure Core Architecture
Secure Core is Proton VPN’s signature security feature. When enabled, it routes your traffic through two separate VPN servers before it reaches its final destination. Crucially, the first server in the chain is always one of Proton’s ultra-secure, company-owned “Secure Core” servers located in high-privacy countries like Switzerland, Iceland, and Sweden. This means that even if the exit server is compromised, an attacker would still be unable to trace the traffic back to your real IP address. It’s an advanced multi-hop system designed for high-risk users like journalists and activists, providing a level of protection that standard VPN connections cannot match.
The Best Free VPN Plan on the Market?
One of the most compelling aspects of this Proton VPN review is its free tier. Unlike most free VPNs that are slow, insecure, and riddled with ads or data caps, Proton VPN’s free plan is genuinely usable and secure. It offers unlimited bandwidth (no data caps), a strict no-logs policy, and access to servers in 3 countries (USA, Netherlands, Japan). It’s an incredible offering for basic privacy protection and a perfect way to experience the service’s commitment to security firsthand. However, the free plan has limitations: speeds are lower than paid plans, and it does not support streaming or P2P traffic.
Speed & Performance Tests
Our Proton VPN review included extensive speed testing. While it is very secure, its speeds are not always as fast or consistent as the top-performing VPNs on the market.
Local and International Speed Results
On our 100Mbps baseline connection, a nearby US server provided an average download speed of 92Mbps, which is a solid result. Proton VPN also includes a “VPN Accelerator” technology that uses various techniques to improve connection stability and speed over long distances. However, we found that performance on international servers was more variable, with speeds sometimes dropping more significantly than competitors. This is a trade-off for its high-security features like Secure Core, which naturally adds latency.
| VPN | Local Speed (US) | International Average |
|---|---|---|
| Proton VPN | 92 Mbps | 79 Mbps |
| NordVPN | 96 Mbps | 86 Mbps |
| ExpressVPN | 97 Mbps | 85 Mbps |
Streaming Performance Review
While Proton VPN is a titan of privacy, its streaming performance is more modest. It focuses on reliably unblocking the most popular services rather than a vast array of niche platforms.
Netflix and Other Major Platforms
In our tests for this Proton VPN review, its “Plus” servers successfully unblocked major platforms like US Netflix, Hulu, Disney+, and BBC iPlayer. However, we found its ability to unblock a wider variety of international Netflix libraries to be less consistent than competitors like NordVPN or ExpressVPN. If your primary goal is to access dozens of different streaming services from around the globe, Proton VPN may not be the most reliable choice.
Torrenting & P2P Performance
Proton VPN is an excellent choice for torrenting. It allows P2P traffic on hundreds of specialized servers, which are clearly marked in the app. A standout feature for torrenters is **port forwarding**, which allows you to redirect incoming connections to bypass NAT firewalls, potentially increasing your P2P download and upload speeds. This, combined with its kill switch, Swiss privacy laws, and no-logs policy, makes it a very safe and powerful option for file-sharing.
User Experience & Device Compatibility
Proton VPN’s apps are well-designed, with a technical, map-based interface that displays a wealth of connection data. While beginners might find it slightly more complex than ExpressVPN’s one-button approach, tech-savvy users will appreciate the level of detail. The apps are available for all major platforms, and a single paid subscription allows for **10 simultaneous connections**.
Proton VPN Pricing & Plans
Proton VPN positions itself as a premium service, and its pricing reflects that. It’s more expensive than budget options like Surfshark, but the cost is justified by its advanced security features and unmatched transparency. The most significant point of caution is its refund policy.

Unlike most competitors who offer a full refund, Proton VPN’s 30-day guarantee is **prorated**. This means if you cancel after 15 days, you will only be refunded for the unused portion of the month, not the full amount you paid. This is a significant drawback and something potential customers should be aware of.
Final Verdict: Is Proton VPN Worth It?
After a full evaluation for this Proton VPN review, our verdict is clear: **yes, it is absolutely worth it, but only for a specific type of user**. If your primary concerns are casual streaming or getting the lowest possible price, there are better options available.
However, if you are a journalist, activist, tech professional, or simply a privacy advocate who demands the highest possible standard of security, transparency, and trustworthiness, Proton VPN is in a class of its own. The combination of its Swiss jurisdiction, open-source apps, audited no-logs policy, and unique Secure Core architecture provides a level of peace of mind that is unmatched in the industry. For those users, Proton VPN is not just the best choice—it’s the only choice.
