Our take: Proton VPN’s privacy case is unusually well-documented — Swiss jurisdiction, fully open-source apps, a no-logs policy independently audited every year since 2022, and a real, published transparency report showing every government data request it has received and refused. Its free plan is a genuine standout: unlimited data with no ads, unlike almost every other “free” VPN. Speed and streaming access lag the fastest paid competitors, but for anyone who weighs verifiable privacy over raw speed, Proton VPN has the strongest documented case of any VPN reviewed on this site.
Key Takeaways
- Headquartered in Geneva, Switzerland — outside the EU and the 5/9/14 Eyes intelligence-sharing alliances.
- No-logs policy independently audited annually since 2022 (Securitum), plus a separate 2020 app audit by SEC Consult — one of the most consistently audited VPNs available.
- Proton’s own transparency report shows 47 legally binding requests for VPN user data received and denied in H1 2026 (458 total since 2017) — denied because no identifying data exists to hand over, not as a policy choice.
- The free plan offers unlimited data with no ads on a limited set of countries — a real standout among “free” VPNs, most of which cap data or monetize user activity.

A Note on How This Review Was Put Together
This review is built from Proton’s own published documentation, audit reports, and transparency report — all independently verifiable public documents — plus independent test results already published by established outlets. It isn’t based on SecureGuides’ own lab testing. We link to sources throughout. If SecureGuides runs its own testing on Proton VPN in the future, this review will be updated to say so explicitly.
Pros and Cons
✅ Pros
- Swiss jurisdiction, outside all major intelligence-sharing alliances
- No-logs policy independently audited annually since 2022 — one of the most consistently audited in the industry
- Fully open-source apps — independently inspectable, not just policy claims
- Publishes a real transparency report with specific, verifiable request/denial figures
- Genuinely unlimited-data free plan with no ads
- Tor over VPN and Stealth obfuscation built into the app
❌ Cons
- Slower than the fastest competitors on paid plans, per most third-party speed tests
- Free plan limited to a handful of countries and 1 device
- More expensive than Surfshark on comparable terms
- Server-count figures vary significantly by source — worth checking Proton’s own site for the current number
The Free Plan: A Genuine Standout
Proton VPN’s free plan is unusual among “free” VPNs: unlimited data, no advertising, and the same no-logs policy and AES-256 encryption as the paid tier. The trade-offs are real — access limited to a small set of countries (commonly cited as 5-10 depending on current configuration), 1 device at a time, no P2P/torrenting, no streaming-optimized servers, and no NetShield ad-blocker or Secure Core multi-hop. Independent 2026 testing found free-tier speeds adequate for HD streaming and everyday browsing, without an artificial throttle. Most competing “free” VPNs impose hard data caps or monetize user activity in some way; Proton’s free tier is funded by paying subscribers instead, which is a meaningfully different (and more honest) model.
Privacy: Why Switzerland and Open Source Matter
Proton is headquartered in Geneva, Switzerland — outside the EU and outside the 5/9/14 Eyes intelligence-sharing alliances, under a legal system with strong data-protection standards. Two things make Proton’s privacy claims unusually checkable rather than just stated:
- Open-source apps. Proton publishes its VPN client source code, letting independent security researchers inspect it directly for hidden logging or vulnerabilities — most VPNs do not do this.
- Annual independent audits. Securitum has audited Proton’s no-logs infrastructure every year since 2022 (most recently in May 2026 — the fifth consecutive annual audit), separate from a 2020 app-security audit by SEC Consult. The 2026 report concluded the examined infrastructure showed no evidence of logging browsing activity, DNS queries, or user-identifiable connection metadata.
The Transparency Report: Real Numbers, Not a Policy Statement
Unlike a policy claim, Proton publishes a dated, specific transparency report. In the first half of 2026, Proton reported receiving 47 legally binding requests for VPN user data — all from Swiss authorities, all denied, because the no-logs architecture meant there was no identifying data to hand over. Proton states it has received 458 such requests total since the service launched in 2017. This kind of specific, dated, sourced disclosure is rarer among VPN providers than marketing pages suggest, and is one of Proton’s clearest differentiators.
Pricing 2026
| Plan | Price | Devices |

| Proton Unlimited (2-year) | Higher tier — includes Mail, Drive, Calendar, Pass | 10 |

Speed and Streaming: Honest Assessment
We haven’t run our own speed tests on Proton VPN. Third-party 2026 results vary significantly by tester and methodology — some report speed loss comparable to top competitors, others report it trailing the fastest VPNs (NordVPN, ExpressVPN) on nearby servers. The consistent theme: fast enough for 4K streaming and everyday use, but not the outright speed leader. Netflix and other streaming access is generally reported as more limited than NordVPN’s or ExpressVPN’s library coverage — check a recently dated third-party test for current specifics, since this changes often.
NetShield, Stealth, and Tor over VPN
NetShield is Proton’s DNS-level ad and tracker blocker, working across all apps on a device rather than a single browser. It has three modes: off, malware-blocking only, and full ad/tracker blocking.
Stealth protocol disguises VPN traffic as ordinary HTTPS to help bypass network-level censorship (e.g., China’s Great Firewall). We haven’t independently tested its current success rate — obfuscation effectiveness changes as censorship systems evolve on both sides, so treat any specific “works in China” claim as unverified in the moment rather than guaranteed.
Tor over VPN routes traffic through the VPN and then the Tor network, adding anonymity at a real speed cost. It’s a genuinely useful built-in option for users who would otherwise need a separate Tor browser, most relevant for journalists, activists, or others in high-risk situations rather than everyday use.

Who Should Use Proton VPN?
Consider Proton VPN if: you want the most independently verifiable privacy story available — Swiss jurisdiction, open-source apps, annual audits, and a real transparency report — or you want a genuinely unlimited-data free plan without ads.
Consider alternatives if: raw speed or the widest streaming library access is your priority (see our NordVPN review or ExpressVPN review), or you need unlimited simultaneous devices on a budget (see our Surfshark review).
Frequently Asked Questions
Is Proton VPN really free?
Yes — the free plan offers unlimited data, no ads, and no logs, though it’s limited to a small set of countries and 1 device. It’s one of the few “free” VPNs that doesn’t monetize user data or impose a hard data cap.
Is Proton VPN better than NordVPN?
For verifiable privacy — Swiss jurisdiction, open-source apps, annual audits, a real transparency report — Proton has the stronger documented case. For speed and streaming library breadth, NordVPN generally leads in third-party tests. It depends on what you’re optimizing for.
Does Proton VPN work in China?
Its Stealth protocol is designed to disguise VPN traffic to help bypass censorship systems, but we haven’t independently verified current reliability there — treat any “it works” claim as unverified in the moment, since censorship detection evolves on both sides.
Is Proton VPN’s no-logs claim verified?
Yes — audited annually by Securitum since 2022 (most recently May 2026), with a separate 2020 app audit by SEC Consult, and backed by a real, dated transparency report showing specific request and denial figures.
How many devices can I use with Proton VPN?
1 on the free plan; 10 on paid plans.
Final Verdict
Proton VPN’s privacy claims are among the most independently checkable of any VPN reviewed on this site: open-source apps, audits every year since 2022, and a transparency report with real, dated, specific figures rather than a policy statement alone. It isn’t the fastest VPN, and its free plan has real limits, but for anyone who weighs verifiable privacy heavily, it has the strongest documented case available.
