Proton VPN is built by the same team behind Proton Mail — one of the largest encrypted email providers, born out of CERN. Unlike most VPN providers, Proton is headquartered in Switzerland, which has some of the strongest privacy laws in the world and is outside EU and US jurisdiction.
Proton VPN's pitch is verifiability: every app is open-source, the no-logs policy has been independently audited, and the parent company's revenue comes from paid subscribers — not advertisers. This review covers what that buys you in 2026, what's still missing, and where Proton VPN beats or trails the competition.
How Fast Is Proton VPN?
Proton VPN's WireGuard performance is in the top tier of independent speed tests by AV-TEST and PCMag. Independent measurements typically show 80-95% of unprotected speed retained on nearby servers.
Long-distance connections (US ↔ Europe) typically retain 60-80% of baseline speed, which is normal for any VPN — distance is the limiter, not the protocol. For streaming, video calls, and everyday browsing, it's not noticeable.
| Metric | Value | Notes |
|---|---|---|
| Nearby Server | ~320 Mbps | on a 400 Mbps connection |
| Long Distance | ~260 Mbps | US → Europe |
| Ping (Nearby) | ~10 ms | minimal latency impact |
Tip: Use WireGuard for the fastest connections. Enable VPN Accelerator (on by default for paid plans) to reduce long-distance latency further.
Security & Privacy Deep Dive
- AES-256 + ChaCha20 — AES-256 (OpenVPN/IKEv2) and ChaCha20-Poly1305 (WireGuard). Both are the same algorithms used in HTTPS, TLS 1.3, and 1Password's vault encryption — well above any "might it be cracked" concern.
- Swiss Jurisdiction — Based in Switzerland — strict privacy laws, no mandatory data retention, and outside the 5/9/14 Eyes surveillance alliances.
- Open-Source Apps — Every Proton VPN app is fully open-source on GitHub. Anyone can inspect the code. Proprietary VPNs require blind trust.
- Independent Audits — Apps and infrastructure audited by Securitum and other third-party firms. Proton has also completed SOC 2 Type 2 compliance.
- Secure Core (Multi-Hop) — Routes traffic through hardened data centers in Iceland, Sweden, or Switzerland before exiting — protecting against endpoint compromises.
- No IP/DNS/WebRTC Leaks — Proton VPN passed all leak tests in independent reviews. DNS queries are encrypted inside the VPN tunnel, and IPv6 is blocked to prevent leaks.
Streaming
Proton VPN works reliably with most major streaming platforms on its Plus and Unlimited plans. The streaming-optimized servers are specifically designed to bypass geo-blocks.
- Netflix (10+ regions including US, UK, Japan)
- Disney+ (US, UK, and more)
- BBC iPlayer
- Amazon Prime Video
- Hulu (US)
- HBO Max / Max
P2P/torrenting is fully supported on dedicated servers with port forwarding available. The free plan does not include streaming optimization or P2P servers.
Note: Streaming works best on the Plus or Unlimited plan. The free tier does not prioritize unblocking.

Our Verdict
Proton VPN is one of the most privacy-focused VPN services available in 2026. Its combination of Swiss jurisdiction, open-source code, independent audits, and a genuinely free tier makes it unique in the VPN industry.
The Plus plan delivers excellent speeds, reliable streaming, and advanced features like Secure Core and NetShield. The only real downsides are slightly higher pricing than budget alternatives and the lack of 24/7 live chat support. If privacy and transparency are your top priorities, Proton VPN is hard to beat.
