Quick Summary
Proton VPN comes from the team behind Proton Mail, the world's largest encrypted email service. Based in Switzerland — one of the strongest privacy jurisdictions in the world — Proton VPN offers a rare combination: a genuinely useful free tier alongside premium features like Secure Core multi-hop routing, NetShield ad-blocking, and speeds that rival top competitors. All apps are open-source and independently audited. While it's slightly more expensive than NordVPN or Surfshark on long-term plans, the privacy credentials, Swiss jurisdiction, and free tier make Proton VPN a compelling choice for privacy-conscious users at every budget level.

Features
Proton VPN is built by cryptography experts from CERN and MIT. Here's what sets it apart:
- Secure Core — Premium feature that routes your traffic through hardened servers in Switzerland, Iceland, or Sweden before exiting. Even if the exit server is compromised, your real IP stays hidden.
- NetShield — DNS-level ad, tracker, and malware blocker. Three levels: off, block malware only, or block everything.
- WireGuard & Stealth Protocol — WireGuard for speed, plus Proton's custom Stealth protocol for bypassing VPN blocks in censored countries.
- Kill Switch & Always-on VPN — Available on all platforms including iOS.
- Split Tunneling — Route specific apps through or outside the VPN tunnel.
- Tor over VPN — Built-in Tor routing through special servers.
- P2P/BitTorrent — Optimized servers for torrenting (paid plans only).
- Proton Ecosystem — Seamlessly integrates with Proton Mail, Proton Drive, and Proton Calendar. One subscription can cover everything.
The free tier includes unlimited bandwidth (recently upgraded from limited), access to servers in the US, Netherlands, and Japan, and no ads — a rarity among free VPNs.
Pricing
| Plan | Monthly | Features |
|---|---|---|
| Free | $0 | 1 device, 3 countries, unlimited data |
| VPN Plus (2yr) | $4.99/mo | 10 devices, 90+ countries, Secure Core, NetShield, P2P |
| VPN Plus (1yr) | $5.99/mo | Same as above |
| Proton Unlimited | $9.99/mo | VPN + Mail + Drive + Calendar |
The Proton Unlimited plan is excellent value if you also use Proton Mail and Drive. The free tier is genuinely useful — not a crippled demo — making it the best free VPN available.
Usability
Proton VPN's apps are polished and modern, with a clean world map interface showing server locations. Connecting is one-click, and the Quick Connect feature automatically picks the fastest available server.
The settings are well-organized without being overwhelming. Power users can dive into protocol selection, split tunneling, and Secure Core, while beginners can just hit connect and forget about it.
Mobile apps are excellent on both iOS and Android, with full feature parity. The Linux client has a GUI (unusual for VPN Linux clients) and works well. Customer support is available via email and a comprehensive knowledge base; live chat is available for paid subscribers.

Frequently Asked Questions
Is Proton VPN really free?
Yes. The free tier offers unlimited data, servers in 3 countries (US, Netherlands, Japan), and 1 device connection. There are no ads, no data selling, and no bandwidth caps.
Is Proton VPN as fast as NordVPN?
Proton VPN is fast, but NordVPN's NordLynx protocol edges it out in most speed tests. Proton VPN retains about 85-90% of your base speed on nearby servers vs NordVPN's 90-92%.
Does Proton VPN work with Netflix?
Yes, on paid plans. Proton VPN reliably unblocks Netflix US, UK, and several other libraries. The free tier does not work with most streaming services.
What is Secure Core?
Secure Core routes your traffic through Proton's hardened servers in Switzerland, Iceland, or Sweden before reaching the exit server. Even if the exit server is monitored, your real IP stays hidden behind the Secure Core server.
Is Proton VPN open source?
Yes. All Proton VPN client apps are fully open-source and available on GitHub. They have been independently audited by Securitum.
How does Proton VPN compare to Mullvad?
Both are privacy-focused. Mullvad offers anonymous accounts and simpler pricing (€5 flat). Proton VPN offers a free tier, more servers (3000+ vs 700), Secure Core routing, and ecosystem integration. Choose Mullvad for maximum anonymity, Proton for a balanced privacy VPN.
