Proton VPN
Proton VPN is the most privacy-focused provider in the category by most measurable criteria: Swiss jurisdiction outside 5/9/14 Eyes alliances, fully open-source clients across all platforms, and four consecutive independent no-logs audits — the most recent by Securitum in August 2025. Secure Core routes traffic through servers in Switzerland, Iceland, or Sweden before it exits to the internet, providing meaningful protection against compromised exit nodes that most competitors simply don't offer. The weaknesses are real: speeds are below the category average (Secure Core adds latency by design), and at $9.99/month on a monthly plan it sits near the top of the pricing range. A free plan with no ads and no speed cap — limited to three server countries — is a genuine differentiator. The right pick for users who prioritize privacy over speed and want the full technical picture before trusting a provider.

- Ease of use7/10
- Price / quality6/10
- Features7.8/10
Ideally suited for
- Journalists, activists, and anyone for whom privacy is a real operational requirement — Swiss jurisdiction and fully open-source code
- Users who need Secure Core — double routing through Switzerland, Iceland, or Sweden before reaching the exit node
- Anyone who wants to test a VPN for free: an ad-free, speed-unlimited plan covering three countries
- Users in countries with DPI and internet censorship: the Stealth protocol is designed to bypass deep packet inspection
Usage scenarios
Secure access, even under surveillance
Secure Core keeps traffic protected even if the exit server is compromised — relevant for remote workers in countries with active monitoring. Latency is above the category average, so for live video calls use standard servers rather than Secure Core.
Streaming with caveats
Netflix and some other services unblock, but reliability is lower than ExpressVPN or NordVPN — not all servers pass geo-restriction checks consistently. Proton VPN is not the first pick for regular 4K streaming.
The privacy-first pick
Swiss jurisdiction, Secure Core, and fully open-source code is a combination no other major provider offers. Four consecutive independent audits confirm no user data is stored.
P2P with confidentiality
P2P is allowed on dedicated servers. Kill Switch and DNS leak protection work correctly. Speed is the limiting factor: Secure Core adds noticeable latency; standard servers are acceptable for most torrenting needs.
Advantages
- Swiss jurisdiction, four consecutive no-logs audits (most recent: Securitum, August 2025), all client code publicly open-source on GitHub
- Secure Core: double routing via CH/IS/SE provides meaningful defense against compromised exit nodes — a protection most competitors don't offer
- Stealth protocol effectively disguises VPN traffic as HTTPS; confirmed to work in China, Iran, and the UAE
- A free plan with no ads, unlimited speed, and unlimited data — rare in the category, limited to three server countries
Disadvantages
- Speeds are below the category average, especially with Secure Core on — routing through extra hops adds latency by design; not the best choice for 4K streaming or online gaming
- $9.99/month on the monthly plan is near the top of the pricing range; the 2-year plan starts at $2.99/month but requires paying two years upfront
- Streaming unblocking lags behind NordVPN and ExpressVPN: Netflix works on a limited set of servers, and some services don't unblock reliably
- Android and iOS apps receive recurring complaints about connection stability in some regions
