Proton VPN Security

Open source, independently audited, and legally protected by Swiss law. Every aspect of our security is publicly verifiable.

🔒

AES-256-GCM Encryption

Every connection uses AES-256-GCM encryption — the same standard protecting classified government information. Computationally infeasible to break.

🔑

Perfect Forward Secrecy

A unique encryption key is generated for every VPN session. Past sessions remain secure even if a key is ever compromised.

🌐

Full Disk Encryption

All Proton VPN servers use full disk encryption. If a server is physically seized, no usable data can be extracted.

⚖️

Swiss Legal Protection

Switzerland's strong privacy laws prohibit mass surveillance and protect Proton from government overreach. We cannot be forced to hand over logs we don't have.

📖

Open Source & Auditable

All our apps are 100% open source and available on GitHub. Independent security firms audit our code and publish their findings.

✅

Independently Verified No-Logs

Our no-logs policy has been tested by real-world events — not just promises. Law enforcement attempts to access user data have yielded nothing.
