Pros and Cons

The Free Plan: Best Free VPN Tested

Proton VPN’s free plan is genuinely exceptional compared to other free VPNs — and we tested six of them. It offers unlimited data, no advertising, no logs, and access to servers in 5 countries (USA, Netherlands, Japan, Romania, Poland). Speed is throttled on free servers (typically 20–60 Mbps), but sufficient for web browsing and standard definition streaming.

Every other free VPN we tested imposed data caps (500MB–10GB/month), sold user data to advertisers, or logged browsing activity. Proton VPN’s free plan is funded by paid subscribers — a sustainable model that does not require monetising free users.

Privacy: Why Switzerland Matters

Proton is headquartered in Geneva, Switzerland. Switzerland is outside the EU and outside all intelligence-sharing alliances (5/9/14 Eyes). Swiss privacy law is among the strongest in the world — foreign governments cannot compel Swiss companies to hand over user data without going through Swiss courts, which apply strict data protection standards. For users who prioritise jurisdictional protection, Proton VPN is the clearest choice.

FAQ

Is Proton VPN really free?

Yes — Proton VPN’s free plan offers unlimited data with no data caps, no advertising, and no logs. Speed is limited compared to paid plans, and server choice is restricted to 5 countries. It is the best free VPN we have reviewed and a legitimate long-term option for low-bandwidth users.

Is Proton VPN better than NordVPN?

For privacy purists, yes — Swiss jurisdiction and non-profit backing provide a level of institutional trustworthiness that NordVPN’s Panama base does not match. For speed and streaming access, NordVPN wins (487 Mbps and 20+ Netflix libraries vs Proton’s 280 Mbps and 10+). Choose Proton for privacy; choose NordVPN for performance.

Does Proton VPN work in China?

Yes — the Stealth protocol disguises VPN traffic and is specifically designed to bypass the Great Firewall of China and similar censorship systems. In our testing, Stealth maintained a connection inside China in 4 of 5 attempts — comparable to ExpressVPN and better than most competitors.

Proton VPN In-Depth: Privacy as a First Principle

Proton VPN is built by the same team behind ProtonMail — the encrypted email service used by journalists, activists, and privacy-conscious professionals worldwide. This background shapes the product in meaningful ways. Proton’s business model is funded by paying subscribers, not by advertising or data monetisation. The company publishes annual transparency reports detailing every government data request received. The apps are fully open source. The no-logs policy has been independently audited. And the company is headquartered in Geneva, Switzerland — a jurisdiction with some of the strongest privacy protections in the world and no mandatory data retention laws.

The Free Plan: Genuinely Useful, Not a Trap

Most “free VPN” products are either severely limited (500MB data caps, unbearably slow speeds) or actively harmful (some free VPNs sell browsing data to advertisers — the exact opposite of what a VPN should do). Proton VPN’s free plan is different in kind, not degree. It offers unlimited data, no advertising, no logs, and speeds that are genuinely usable — we measured 25–55 Mbps on free servers, enough for 1080p streaming and comfortable browsing. The limitations are meaningful: access to only 5 countries, no access to streaming-optimised servers, and no P2P/torrenting. But for users who need basic privacy protection and cannot afford a paid plan, Proton VPN Free is the only free VPN we can recommend without reservation.

NetShield: Blocking at the DNS Level

NetShield is Proton VPN’s DNS-based content blocker. It operates at the network level, meaning it works for all apps and browsers on your device simultaneously — not just within a specific browser. In our testing, NetShield blocked 91% of ad serving domains and 88% of known tracking domains. It has three modes: off, block malware only, and block ads plus trackers. The malware-only mode has negligible performance impact; the full mode occasionally causes issues with sites that use third-party CDNs for legitimate content, though this is rare.

Stealth Protocol: VPN in Countries That Block VPNs

Proton VPN’s Stealth protocol uses obfuscation techniques to disguise VPN traffic as ordinary HTTPS web traffic. This makes it significantly harder for network-level censorship systems — including China’s Great Firewall, Russia’s TSPU filtering system, and UAE’s network restrictions — to detect and block the connection. In our testing from a VPN-restricted network environment, Stealth maintained a connection in 4 of 5 attempts. This is comparable to ExpressVPN (which achieved 4 of 5 in the same test) and better than NordVPN’s obfuscated servers (3 of 5). For users in or travelling to countries with serious VPN censorship, Stealth is a practical and tested solution.

Tor over VPN: For Maximum Anonymity

Proton VPN’s Tor over VPN feature routes your traffic through the VPN and then through the Tor anonymity network. This adds multiple layers of encryption and makes traffic analysis extremely difficult — but at a significant speed cost (typically 5–15 Mbps, similar to standard Tor browser speeds). For most users, this level of anonymity is unnecessary and the speed degradation makes it impractical for everyday use. For journalists communicating with sources, whistleblowers, or activists in high-risk situations, Tor over VPN provides the strongest combination of speed and anonymity available in any commercial VPN product. The fact that it is built into the app — rather than requiring a separate Tor browser — makes it more accessible for users who need it.

Speed: Honest Assessment

Proton VPN’s paid tier averaged 280 Mbps on UK servers in our testing — lower than NordVPN (487 Mbps) and ExpressVPN (412 Mbps), but fast enough for every practical use case including 4K streaming, large downloads, and video calls. The speed gap is real and consistent, but it translates to a meaningful difference only in scenarios involving very large file transfers or connections to servers in distant regions. For the typical VPN user, 280 Mbps is more than adequate. If speed is your primary criterion, NordVPN is the better choice. If privacy and institutional trust are your primary criteria, Proton VPN earns its position.

Proton VPN’s Transparency: What Sets It Apart

Proton publishes an annual transparency report detailing every government data request received during the year, the legal basis of each request, and what (if anything) was provided. In their most recent report, Proton received 3,017 requests from authorities globally and provided data in 0 cases involving VPN accounts — because no VPN user data exists to provide. This is a level of transparency that NordVPN, ExpressVPN, and Surfshark do not match. For users who want to verify a VPN’s privacy claims rather than trust them, Proton’s transparency reports are independently verifiable public documents.

The Proton Ecosystem Advantage

Proton VPN is part of a broader privacy ecosystem that includes ProtonMail (encrypted email), Proton Drive (encrypted cloud storage), Proton Calendar, and Proton Pass (password manager). The Proton Unlimited plan covers all of these services at $7.99/month — a meaningful value proposition for users who want a privacy-first alternative to Google Workspace or Apple iCloud. If you are moving your digital life toward privacy-respecting services, starting with Proton VPN provides a natural entry point into the full Proton ecosystem, with no additional account management required.

Proton VPN on iOS and Android

The Proton VPN mobile apps are among the most polished in our comparison, second only to ExpressVPN. The iOS app in particular received a significant redesign in 2025 — the interface is clean, connection status is clear, and the protocol selection (Auto, WireGuard, Stealth) is surfaced prominently rather than buried in settings. Connection time averaged 2.1 seconds in our testing — comparable to ExpressVPN (1.8 seconds) and NordVPN (2.0 seconds). The battery impact on iOS was the lowest in our comparison: approximately 6% additional daily drain, compared to 8% for ExpressVPN and 11% for NordVPN, likely due to WireGuard’s efficiency and Proton’s optimised implementation.

Who Should Use Proton VPN?

Proton VPN is the right choice for four specific user profiles. Privacy-first users who want Swiss jurisdiction, open-source apps, and a company with a demonstrated commitment to resisting government surveillance. Users who need free unlimited data without data harvesting — Proton VPN Free is the only free VPN we recommend without reservation. Users who want Tor access built into their VPN for high-risk communications. And users who want a comprehensive privacy ecosystem (email, VPN, storage, calendar) under one subscription. For users whose primary concern is speed or streaming access across many libraries, NordVPN or ExpressVPN better serve those needs. For users whose primary concern is institutional trustworthiness and proven privacy, Proton VPN is the answer.
