ProtonVPN Review

Most people reach for a VPN because something made them uncomfortable — an airport Wi-Fi warning, a news story about data brokers, a moment where they realized how visible their internet activity really is. ProtonVPN was built by people who spent years inside that problem professionally.

The founding team came from CERN, the European research laboratory that invented the World Wide Web. They later built Proton Mail, one of the most widely trusted encrypted email services in the world. ProtonVPN grew out of the same mission: give ordinary people the same privacy tools that journalists, activists and researchers depend on in high-stakes situations.

The result is a VPN that scores 88 out of 100 in our independent methodology — second only to NordVPN in the providers we have reviewed. That gap is narrow, and where ProtonVPN makes up for it matters: Switzerland-based jurisdiction, a no-logs policy verified in court, Secure Core multi-hop routing, and a genuinely usable free tier that costs nothing. For users who prioritize privacy pedigree over raw speed, ProtonVPN is the strongest choice in this category.

History & Trust

Origins at CERN and Proton Mail

ProtonVPN was founded in 2017, but its roots go back to 2014 when a group of CERN and MIT scientists launched Proton Mail after being frustrated by the NSA surveillance revelations in the Snowden documents. That context matters. ProtonVPN wasn’t created as a side project by a software holding company looking to monetize internet traffic. It was built by people who understood surveillance at a technical and institutional level and wanted a counterweight.

The company operates as Proton AG, headquartered in Geneva, Switzerland. It is employee-owned, not backed by venture capital or a larger media conglomerate. That ownership structure removes the most common conflict of interest in the VPN industry: the pressure to monetize user data when growth slows.

Swiss Jurisdiction

Switzerland sits entirely outside the Five Eyes, Nine Eyes and Fourteen Eyes intelligence-sharing alliances. Swiss law does not require telecommunications companies to store customer metadata for law enforcement access. This is meaningfully different from VPNs headquartered in the US, UK or other alliance countries, where legal obligations to retain or share data are stronger and less transparent.

For you, this means a court order from a US or EU authority cannot compel Proton to hand over Swiss-stored data. A Swiss court would need to independently authorize disclosure — a much higher bar.

No-Logs Policy Verified in Court — Not Just Promised

Many VPN providers claim a no-logs policy. ProtonVPN’s has been tested by the legal system. In 2021, Swiss authorities required Proton to comply with a court order related to a criminal investigation. The result confirmed what Proton had always stated: because ProtonVPN does not log connection metadata, IP addresses or session timestamps, there was nothing to provide.

“The case demonstrated that even under legal compulsion, ProtonVPN’s architecture could not produce user activity logs — because none exist. The system is designed so that compliance with a court order and user privacy are not in conflict.” — ProtonVPN transparency report

This is a qualitatively different level of assurance than a policy document. The no-logs claim has been stress-tested by real legal pressure, not just a marketing audit.

Open-Source and Independently Audited

All ProtonVPN client applications — Windows, macOS, Linux, iOS and Android — are fully open-source and available on GitHub. Independent security researchers can audit the code themselves. This is a higher bar than NordVPN, which has released some components but not full applications.

ProtonVPN also commissions regular third-party security audits from firms including SEC Consult and Cure53. Audit results are published publicly on Proton’s blog. If you want a VPN where the privacy claims are verifiable rather than taken on faith, ProtonVPN’s open-source posture and audit record are industry-leading.

Security & Privacy

Encryption and Protocol Stack

ProtonVPN uses AES-256-GCM encryption with 4096-bit RSA for key exchange and HMAC-SHA384 for authentication — the same encryption standard used by financial institutions and government agencies. Every connection is protected by Perfect Forward Secrecy, meaning a new encryption key is generated for each session. Even if a session key were somehow compromised in the future, past sessions could not be decrypted.

Supported protocols include:

• WireGuard — the default on most platforms, offering the best balance of speed and security
• OpenVPN (UDP and TCP) — battle-tested, widely compatible, useful for network environments that inspect WireGuard traffic
• IKEv2/IPSec — fast reconnection on mobile when switching between Wi-Fi and cellular
• Stealth — ProtonVPN’s proprietary obfuscation protocol, designed to disguise VPN traffic as regular HTTPS traffic in censored networks like China, Iran and Russia

The Stealth protocol is a meaningful differentiator. Most VPNs offer OpenVPN obfuscation at best. Stealth is actively maintained and designed for adversarial network conditions.

Secure Core: Multi-Hop Routing

Secure Core is ProtonVPN’s multi-hop architecture. When enabled, your traffic is routed through a hardened server in a privacy-friendly country — Switzerland, Iceland or Sweden — before exiting through a standard VPN server in your destination country. An attacker observing the exit server cannot trace traffic back to you because the entry point is separated geographically and jurisdictionally.

This is relevant in situations where a VPN server in a target country might be compromised, surveilled or legally compelled. Secure Core adds latency, but for users in high-risk situations — journalists, researchers, activists — it provides a meaningful additional layer of protection that most VPNs do not offer.

Tor Over VPN

ProtonVPN includes Tor over VPN servers, which route traffic through the Tor anonymity network after it leaves the VPN tunnel. This combines VPN encryption with Tor’s multi-layer routing without requiring the Tor Browser. It is slower than standard VPN connections but provides the highest anonymity available in a consumer VPN product.

DNS Leak and Kill Switch

ProtonVPN routes all DNS queries through its own servers over the VPN tunnel, eliminating the risk of DNS leaks to your ISP. The kill switch is available on all major platforms and blocks internet access immediately if the VPN connection drops — preventing the brief exposure window that occurs when a VPN reconnects.

A “Permanent Kill Switch” mode, available on desktop, blocks all internet access even when the VPN is manually disconnected. This is useful for users who want to ensure no traffic ever travels outside the tunnel under any circumstances.

Speed & Performance

Lab Results: 580 Mbps, Rank #12 of 22

In our speed testing methodology, ProtonVPN recorded an average of 580 Mbps on a 1 Gbps fiber baseline with a latency of 22ms. That ranks it 12th of the 22 providers we tested — in the upper half but not at the top of the speed rankings.

To be direct about what this means: NordVPN, ExpressVPN and a handful of others are faster in raw throughput. If you are a power user who streams 4K video on multiple devices simultaneously while also downloading large files, that gap is real. For the vast majority of users — including HD streaming, video calls, general browsing and moderate file transfers — 580 Mbps is far more than you will ever saturate.

VPN Accelerator

ProtonVPN includes a proprietary performance optimization called VPN Accelerator, which uses parallelization techniques to improve speeds on high-latency connections. In practice, this reduces the gap between ProtonVPN’s throughput and faster competitors, particularly when connecting to distant servers. It is enabled by default and requires no configuration.

WireGuard Performance

WireGuard is the foundation of ProtonVPN’s fastest connection mode. Compared to OpenVPN, WireGuard establishes connections faster, reconnects seamlessly when switching networks and runs with a smaller code surface area (roughly 4,000 lines versus OpenVPN’s 70,000+), which reduces the risk of implementation bugs. ProtonVPN’s WireGuard implementation uses a custom identity-hiding system to prevent user identification from WireGuard’s connection logs.

Server Network

ProtonVPN operates 4,000+ servers in 120+ countries. This is a smaller network than NordVPN (8,900+ servers) or CyberGhost, but coverage is broader than many privacy-focused alternatives. The server locations include countries that most VPNs skip, which matters if your use case involves specific regional access.

All servers use RAM-only storage, meaning no data is written to disk and every reboot wipes the server state clean.

Streaming & Content Access

ProtonVPN unlocks content on 6+ major streaming platforms, including Netflix, Disney+, BBC iPlayer, Amazon Prime Video, Hulu and Max. Streaming performance is reliable on standard VPN servers for most regions.

A few important notes:

• Netflix works across multiple regions (US, UK, JP and others) but not all regional libraries are guaranteed on every server. The dedicated streaming servers are the most reliable option.
• BBC iPlayer access requires a UK server and works consistently in our testing.
• Secure Core servers are not optimized for streaming — the multi-hop routing adds latency that can cause buffering on HD content. Use standard servers for streaming.
• ProtonVPN does not publish a list of “streaming-optimized” servers the way some competitors do. Server selection for streaming can require trial and error.

If streaming is your primary use case and you want a VPN with more explicit streaming infrastructure and higher speed headroom, NordVPN or ExpressVPN have an edge. ProtonVPN handles streaming competently, but it is not the service’s core focus.

Pricing & Plans

ProtonVPN’s pricing structure is unusual among VPNs in two important ways: it offers a genuinely unlimited free tier with no logging, and its paid plans bundle the broader Proton ecosystem rather than just the VPN.

Plan Comparison

Plan	Monthly Price	2-Year Price	Devices	Key Features
Free	$0	$0	1	5 countries, medium speed, no logs
VPN Plus	$9.99/mo	$2.49/mo	10	All servers, Secure Core, Streaming, Tor, Stealth
Proton Unlimited	$12.99/mo	$7.99/mo	10	Everything in Plus + Proton Mail, Drive, Pass, Calendar

The Free Tier: Genuinely Usable

Most “free VPNs” are either severely limited, ad-supported, or monetize your data. ProtonVPN’s free tier is different: it is explicitly loss-leader positioning for a company that makes money on paid subscriptions, not user data.

The free tier offers:

• No data caps or bandwidth limits
• No logging or data monetization
• Servers in 5 countries (US, Netherlands, Japan, Romania, Poland)
• One device connection
• Standard VPN speeds (not the highest priority on shared infrastructure)

The limitation is server choice and speed priority, not surveillance. If you need a free VPN for occasional use, ProtonVPN Free is the most trustworthy option in the category. For our full breakdown, see best free VPN options.

VPN Plus: The Sweet Spot

At $2.49/month on the 2-year plan, VPN Plus unlocks the full feature set: Secure Core, Stealth protocol, Tor over VPN, all streaming servers and access to the complete 120+ country network. This is competitive with NordVPN’s entry-level 2-year pricing and delivers a stronger privacy architecture.

Proton Unlimited: The Ecosystem Play

At $7.99/month on the 2-year plan, Proton Unlimited bundles the VPN with Proton Mail (encrypted email), Proton Drive (encrypted cloud storage), Proton Pass (password manager) and Proton Calendar. If you already pay separately for a password manager or cloud storage, the bundle frequently works out cheaper than the sum of its parts.

For users who want a privacy-first alternative to Google Workspace or iCloud, Proton Unlimited represents meaningful value beyond just the VPN.

Provider Comparison

VPN Provider	Best Monthly Price	Money-Back	No-Logs Verified	Open Source
ProtonVPN	$2.49/mo (2-yr)	30 days	Court-verified	Yes (full apps)
NordVPN	$3.39/mo (2-yr)	30 days	Audit-verified	Partial
ExpressVPN	$6.67/mo (1-yr)	30 days	Audit-verified	Partial
Mullvad	$5.00/mo (flat)	30 days	Audit-verified	Yes
Surfshark	$2.19/mo (2-yr)	30 days	Audit-verified	No

ProtonVPN’s price is competitive, its no-logs verification is stronger than any competitor except Mullvad, and it is the only major VPN with fully open-source applications.

Who Should Use ProtonVPN

Privacy-first users who want verifiable claims. If you need more than marketing promises — court-tested no-logs, open-source code, Swiss jurisdiction — ProtonVPN provides a level of verifiability that most VPNs cannot match.

Journalists, researchers and activists. Secure Core, Tor over VPN and the Stealth protocol are purpose-built for adversarial environments. ProtonVPN is explicitly recommended by digital security guides for high-risk users.

Proton ecosystem users. If you already use or want Proton Mail, the Unlimited bundle makes the VPN nearly cost-free as an add-on.

Users who need a trustworthy free option. ProtonVPN Free is the only no-cost VPN we would recommend without significant caveats. It doesn’t monetize you — it’s just the entry point to a paid product.

Travelers to censored regions. The Stealth protocol’s obfuscation makes ProtonVPN one of the more reliable options in countries where VPN traffic is detected and blocked. See our guide to VPN options for privacy-focused users for context.

Users who care about open-source software. If auditable code is a requirement, ProtonVPN is the only major VPN provider with fully open-source client applications across all platforms.

Limitations

Choosing ProtonVPN involves a clear set of trade-offs. These are honest:

• Speed rank is #12 of 22. ProtonVPN is fast enough for nearly all use cases, but it is not the fastest VPN we tested. NordVPN, ExpressVPN and several others deliver higher throughput. If maximum speed is the primary criterion, look elsewhere.

• 10 simultaneous devices. This matches NordVPN and most competitors, but Surfshark and some others offer unlimited simultaneous connections. If you have a large household or want to install on every device without thinking about it, that limit eventually matters.

• Secure Core degrades speed. The multi-hop routing is excellent for privacy but adds meaningful latency. Streaming and gaming on Secure Core servers is noticeably slower than standard servers.

• Streaming server selection requires trial and error. ProtonVPN doesn’t publish which specific servers reliably unlock which streaming libraries. Users who want a more explicit streaming experience will find NordVPN or ExpressVPN’s infrastructure easier to navigate.

• 4,000 servers vs. 8,900+ for NordVPN. A smaller server count means more users per server at peak times in popular locations. In practice this rarely causes problems, but it is the honest trade-off for a privacy-focused provider vs. a scale-focused one.

• Free tier is one device only. The free plan’s single-device limit means it does not cover a full household. It is appropriate for personal use, not a family setup.

Frequently Asked Questions

Is ProtonVPN really based in Switzerland, and does that matter?

Yes, Proton AG is headquartered in Geneva under Swiss law. Switzerland is outside the Five, Nine and Fourteen Eyes surveillance alliances and has stronger privacy protections than most other jurisdictions. Courts in the US, UK or EU cannot directly compel Proton to hand over user data — a Swiss court must independently authorize any disclosure. In 2021, a Swiss court order confirmed that ProtonVPN had no connection logs to provide, which verified the no-logs policy under real legal pressure.

What is Secure Core and when should I use it?

Secure Core routes your traffic through a hardened server in Switzerland, Iceland or Sweden before it exits through a regular VPN server in your destination country. An observer at the exit point cannot trace traffic back to your real IP because the connection appears to originate from the Secure Core server in a privacy-friendly country. Use Secure Core when you are concerned about server-level compromise or surveillance — for example, when connecting to servers in countries with heavy government oversight. Expect a speed reduction of 30–50% compared to standard servers.

Can ProtonVPN be used in China or other countries that block VPNs?

ProtonVPN’s Stealth protocol is specifically designed to evade VPN detection in censored networks. It disguises VPN traffic as ordinary HTTPS web traffic. While no VPN is 100% reliable in China given ongoing detection efforts by the Great Firewall, ProtonVPN with Stealth enabled is among the more consistently tested options. Results vary by location and timing — no provider can guarantee access in every scenario.

How does ProtonVPN’s free tier compare to other free VPNs?

Most free VPNs limit bandwidth, log activity, serve ads or monetize user data in less obvious ways. ProtonVPN Free has no data cap, no logging, no ads and no data monetization. The limitations are server choice (5 countries), device count (1) and speed priority (paid users get faster access during congestion). It is funded by paid subscribers, not by selling user data. It is the only free VPN we recommend without meaningful caveats.

Does ProtonVPN work with Netflix?

Yes, ProtonVPN unlocks Netflix in multiple regions including the US, UK and Japan. Performance is reliable on standard servers. Not every server in every country will consistently access every Netflix regional library — if a connection doesn’t work, switching to a different server in the same country usually resolves it. Secure Core servers are not recommended for streaming due to additional latency.

How does ProtonVPN compare to NordVPN?

NordVPN scores 94/100 in our methodology versus ProtonVPN’s 88/100. NordVPN has a larger server network (8,900+ vs. 4,000+), faster raw throughput (ranked #5 vs. #12 in speed tests) and more streaming infrastructure. ProtonVPN leads on privacy architecture: Swiss jurisdiction vs. Panama, court-verified no-logs vs. audit-verified, fully open-source apps vs. partial, and features like Secure Core and Tor over VPN that NordVPN does not offer. The right choice depends on whether your priority is maximum performance or maximum privacy assurance.

The Bottom Line

ProtonVPN earns 88/100 in our methodology — the second-highest score among the 22 providers we evaluated, behind NordVPN.

What separates it from every competitor is the depth of its privacy architecture. Swiss jurisdiction, a no-logs policy that has been tested in court rather than just promised on a webpage, fully open-source applications, Secure Core multi-hop routing, and a Stealth protocol built for adversarial networks. These are not marketing features. They are structural choices made by a company founded specifically to solve the privacy problem, not to build a product category.

The honest caveats: if you need maximum speed, NordVPN edges it out. If you need unlimited simultaneous devices, Surfshark wins on that metric. If streaming is your primary use case, the infrastructure is solid but not as explicitly optimized as NordVPN’s.

But if what you want is a VPN where the privacy claims are verifiable — where you can read the code, review the audit reports, check the court record and understand the legal jurisdiction — ProtonVPN stands in a category of one among mainstream providers. The 88 score reflects a service that executes excellently across nearly every dimension, with only narrow gaps that matter mainly to power users.

For privacy-conscious users, the Proton Unlimited bundle at $7.99/month on a 2-year plan is worth evaluating seriously. It replaces your email provider, cloud storage, password manager and VPN with a single privacy-first stack — often at a lower combined cost than the alternatives it replaces.

Next step: Start with the free tier to verify it works for your devices and location. If it does, the VPN Plus plan at $2.49/month on a 2-year commitment is the right level for most users. Try it against your real network before committing — the 30-day money-back guarantee makes that risk-free.
