Our verdict
Proton VPN is the rare VPN that's both deeply privacy-focused and genuinely polished, and it's home to the best free tier in the business — unlimited data, no ads, no catches. The open-source, audited apps, Swiss jurisdiction, Secure Core multi-hop routing and censorship-resistant Stealth protocol make it a serious tool for anyone who wants to verify their VPN rather than simply trust it, while the paid network of 8,500+ servers is fast and great for streaming.
Pick it if you value privacy and transparency, want a credible free option to start with, or already live in the Proton ecosystem. It's a top choice for users in restrictive networks and for anyone who prizes open-source, audited software.
Skip it if you want the absolute lowest paid price or unlimited simultaneous devices — Surfshark wins there — or if you need a free tier that's optimized for streaming, which Proton's deliberately is not. Casual users who just want one-tap simplicity may find ExpressVPN cleaner.

Overview
What Proton VPN is
Proton VPN comes from Proton, the Swiss company behind the encrypted email service Proton Mail, and it carries that same security-first DNA. Founded in 2017 and based in Switzerland, it runs a large 8,500+ server network across 110 countries and is built around two things most rivals can't claim together: fully open-source apps on every platform and the best genuinely free tier in the business. Its standout feature, Secure Core, routes your traffic through hardened servers in privacy-friendly countries before it exits, hardening you against network-based attacks.
Who it's for
Proton VPN is for the privacy-minded user who also wants real polish and a credible free option. It suits people who care about open-source transparency and Swiss jurisdiction, anyone who wants to try a quality VPN at no cost, and existing Proton ecosystem users. It's also a capable streaming and torrenting VPN on the paid plan. Bargain hunters chasing the absolute lowest sticker price may prefer Surfshark.
Speed & performance
Proton VPN's WireGuard support delivers strong, consistent speeds, and its VPN Accelerator technology helps wring extra throughput out of long-distance connections. The paid network is large and well-provisioned, so congestion is rarely an issue. The free tier is slower and limited to a few countries by design, but the paid experience is fast enough for 4K streaming and large downloads.
Privacy & logging
This is core territory for Proton. The no-logs policy is independently audited, the apps are open source and audited, and Switzerland offers some of the strongest privacy law in the world, outside EU and US intelligence-sharing frameworks. Secure Core adds defense-in-depth by multi-hopping through hardened locations, and there's a built-in Tor-over-VPN option. For users who want to verify rather than trust, the open-source codebase is a genuine differentiator.
Security features
You get a dependable kill switch, NetShield ad/tracker/malware blocking, Secure Core multi-hop routing, the censorship-resistant Stealth protocol, Tor-over-VPN, and full leak protection. The combination of open-source clients and Secure Core makes Proton VPN one of the most security-serious consumer options, particularly for users in hostile network environments.
Servers & streaming
With 8,500+ servers in 110 countries, the paid network is one of the largest available, and it reliably unblocks Netflix, Disney+, BBC iPlayer and more. The free plan deliberately omits streaming optimization and limits you to a handful of countries, so streamers should be on a paid tier. P2P is supported on the paid network.
Pricing & plans
Proton VPN offers the rare combination of a legitimately useful free plan — unlimited data, no ads, a few server locations — and paid plans from around $4.49/month, with 10 simultaneous devices and a 30-day money-back guarantee. There are no data caps or speed throttling tricks designed to push you off the free tier into paid the way some "freemium" VPNs do. Bundles with the wider Proton suite add value for ecosystem users.
Bottom line
Proton VPN is the principled all-rounder: Swiss, open-source, audited, and home to the best free tier around, with a fast and capable paid network on top. If privacy plus transparency plus a real free option matters to you, it's the standout. If you want the cheapest paid plan with unlimited devices, look at Surfshark.

Frequently asked questions
Proton VPN is best for privacy-minded users who also want transparency and a credible free option. Its open-source audited apps, Swiss jurisdiction and Secure Core routing make it a serious privacy tool, while the paid network handles streaming and torrenting well. It's also the go-to if you want a quality free VPN.
Yes. Proton VPN's no-logs policy is independently audited, and uniquely its apps are fully open source and have also been audited. Combined with Switzerland's strong privacy laws, that makes it one of the most verifiable and trustworthy VPNs available.
On paid plans, yes. The Plus tier reliably unblocks Netflix, Disney+, BBC iPlayer and others across many regions. The free plan is deliberately not optimized for streaming and limits you to a few countries, so streamers should choose a paid tier.
Paid Proton VPN is fast, with strong WireGuard speeds and VPN Accelerator technology that boosts long-distance performance. It's comfortable for 4K streaming and large downloads. The free tier is intentionally slower and more limited.
Paid plans allow up to 10 simultaneous device connections, enough for most households. The free plan is limited to a single device at a time, which is typical for a no-cost tier.
Yes, and it's the best in the business. The free tier offers unlimited data with no ads and no caps, limited to a handful of server locations and one device. There are no throttling tricks designed to force you into paying.
Proton VPN is based in Switzerland, which has some of the strongest privacy laws in the world and sits outside EU and US intelligence-sharing frameworks. That jurisdiction, plus audited open-source apps, makes it a standout for privacy.
Yes, on the paid network, which supports P2P traffic. A reliable kill switch, leak protection and the option of Secure Core routing make it a safe torrenting choice. The free tier does not support P2P.
Proton VPN leads on transparency thanks to fully open-source audited apps and its standout free tier. NordVPN offers more features and slightly faster speeds, while Surfshark is cheaper with unlimited devices. Choose Proton if open-source privacy and a real free option matter most.
In most countries, using a VPN is completely legal. A few nations restrict or ban VPNs, so check local law before traveling. Proton VPN's Stealth protocol is designed to work in restrictive networks, but legality still depends on where you are.
