Proton VPN Review — 2026 Test Results (Pros and Cons)

Our Proton VPN review looks at how the service performs in real-world use, from speed and streaming to security and everyday usability. Created by the team behind Proton Mail, Proton VPN combines a strong privacy foundation with a range of features designed for different types of users.

Based in Switzerland, Proton VPN offers an audited no-logs VPN policy, fully open-source apps, and powerful tools including Secure Core, NetShield, and port forwarding. Secure Core helps bypass network censorship, NetShield blocks trackers and ads at the DNS level, and port forwarding makes it a strong choice for P2P users.

But Proton VPN isn’t just for privacy enthusiasts. Its premium Plus plan gives you access to a global network spanning 20,600+ servers in 148 countries. Powered by WireGuard, Proton VPN delivers impressive speeds and reliably unblocks services including Netflix, Max, Disney+, Hulu, and BBC iPlayer.

Read on to see how this Swiss provider performs in real-world testing and whether it’s the right VPN for you.

How we test VPNs

We put Proton VPN through real-world testing, covering its speed, security, features, and overall performance.

Here’s what we looked at:

1. Speed performance: Multiple speed tests across local and international servers in the US, UK, Europe, and Asia using a dedicated 1 Gbps fiber connection.
2. Security and leak tests: IPv4, IPv6, and WebRTC leak checks, plus sudden connection drops to test the Kill Switch.
3. Streaming and unblocking: Real-world tests with Netflix, Max, Disney+, and Hulu across different server locations.
4. Customer support: Anonymous tests of 24/7 live chat and email support, including response times and technical knowledge.
5. Value: We compared Proton VPN’s pricing, privacy features, infrastructure, and overall package with leading providers such as NordVPN and ExpressVPN.

Proton VPN background

Proton AG is a well-known Swiss privacy company best known for Proton Mail and Proton VPN. It was founded in 2014 by scientists who met at CERN and is primarily owned by the non-profit Proton Foundation, giving the company a structure designed to keep privacy at the heart of its business.

Based in Switzerland, Proton VPN operates outside the 5/9/14 Eyes surveillance alliances and follows a strict no-logs policy. Its privacy claims have been backed by five consecutive annual third-party audits, while its full-disk-encrypted servers are designed to keep user activity private.

Proton has also continued to improve its VPN technology. Its newer Proton Protocols update modernizes the underlying WireGuard implementation, adding features such as automatic conflict detection and faster connection times.

Proton VPN pros and cons

VPN apps

The Proton VPN desktop and mobile apps use a polished dark-mode design that balances simplicity with plenty of control. Key features are organized across a few main sections:

• Countries tab – Browse standard servers or filter by Secure Core, P2P, and Tor over VPN.
• Profiles tab – Create and save custom connection profiles for different tasks.
• Interactive world map – View server locations around the world and connect with a single click, while keeping an eye on live connection stats.

Protocol and platform support

Proton VPN offers dedicated apps for Windows, macOS, Linux, iOS, Android, Android TV, Fire TV, and Apple TV, plus browser extensions for Chrome and Firefox.

Depending on the platform, you can use WireGuard, OpenVPN, or IKEv2. The Stealth protocol is also available on macOS, iOS, Android, and Linux, helping Proton VPN work on networks that block or restrict VPN connections.

Native port forwarding

Proton VPN supports native port forwarding, which can improve P2P transfers and torrent seeding. It’s built into the Windows and macOS apps, while Linux users can access it through the graphical app or Proton’s standalone CLI utility.

The Countries tab lets you select a country and if desired a specific server in that country. This is also where you can select one of the specialty servers: Secure Core, P2P, and Tor over VPN.

Advanced Linux GUI client

Unlike many VPNs that leave Linux users with a basic command-line interface, Proton VPN offers a full graphical interface (GUI). Its modern GTK4-based app supports major distributions including Ubuntu, Debian, and Fedora, while also bringing features such as NetShield DNS filtering and split tunneling to Linux users.

Privacy and security

Proton VPN packs a strong set of privacy and security tools designed to protect your connection and keep your online activity private:

• Kill switch – Blocks internet traffic if the VPN connection drops, helping prevent IP leaks.
• DNS leak protection – Routes DNS requests through Proton VPN’s private DNS servers.
• NetShield ad blocker – Uses DNS filtering to block ads, trackers, and malware.
• Split tunneling – Lets selected apps or IP addresses bypass the VPN tunnel.
• Secure Core – Routes traffic through hardened Proton VPN servers in privacy-friendly locations before connecting to the internet.
• Tor over VPN – Sends traffic through the Tor network without requiring a separate Tor browser.

3-state kill switch

Proton VPN goes beyond a standard kill switch with its advanced kill switch. When enabled, it blocks all internet traffic unless a secure VPN connection is active and stays in place even after a system reboot.

Our stress tests found zero IPv4, IPv6, or WebRTC leaks during forced VPN disconnections.

Split tunneling

Split tunneling is useful for keeping latency-sensitive gaming traffic outside the VPN or avoiding VPN restrictions on banking platforms.

Previously, using split tunneling could mean disabling the kill switch. Proton VPN has now fixed this on Windows, allowing Split Tunneling, Kill Switch, and NetShield to run together without extra configuration.

NetShield ad and malware blocker

NetShield uses DNS-level filtering to block ads, trackers, and known malware domains before they load. Because it works at the network level rather than through a browser extension, it can help reduce page load times and save bandwidth.

Tor over VPN and P2P routing

Proton VPN’s Tor servers route your traffic through the Tor network, letting you access .onion websites through a regular browser without needing to download or configure the Tor Browser.

For P2P file sharing, Proton VPN offers dedicated P2P servers designed for fast downloads and seeding. Server load indicators also make it easier to avoid busy locations and find a faster connection.

Proton ecosystem

One of the nice things about Proton VPN is that it’s part of a much larger privacy-focused ecosystem. The same Swiss company also offers Proton Mail, Proton Drive, Proton Pass, and Proton Calendar, all designed to work together under one account:

• Proton Mail – Encrypted email with tracking protection.
• Proton Drive – Encrypted cloud storage with built-in Docs.
• Proton Pass – A secure password manager with hide-my-email aliases and breach alerts.
• Proton Calendar – An encrypted calendar designed to keep your schedule private.

If you want to replace more of the services you use from companies like Google or Microsoft, the Proton Unlimited plan bundles the premium versions of these apps into one subscription. That makes the wider Proton ecosystem a useful bonus for anyone already considering Proton VPN.

App settings configuration

Proton VPN keeps its main settings organised into two sections: Connection and General.

Connection settings

The Connection tab gives you control over protocols, DNS filtering, the kill switch, and other network features:

• Protocol selection – The Smart option automatically chooses between WireGuard, OpenVPN, Stealth, and IKEv2 based on your connection.
• NetShield – Choose whether to block malware only or also block ads and trackers.
• Kill switch – Use the standard kill switch or the more restrictive Advanced Kill Switch.
• Port forwarding and split tunneling – Enable port forwarding for P2P traffic and choose which apps bypass the VPN.
• VPN Accelerator – Uses multi-threaded processing to help improve speeds over long-distance connections.

General settings

The General tab handles startup behaviour and the app’s appearance:

• Startup behavior – Choose whether Proton VPN starts and connects automatically when your device boots.
• Default profile – Set a preferred connection, such as the fastest country or a custom profile.
• Interface design – Change the app language and switch between light and dark modes.

Advanced network settings

The Advanced section offers more control for users who want to fine-tune their connection:

• Alternative routing – Bypasses local network blocks and censorship firewalls by establishing connections over alternative hidden paths.
• Custom DNS resolvers – Allows users to input preferred third-party DNS servers (such as Cloudflare or OpenDNS) instead of the default secure Proton DNS.
• NAT type selection – Switches between Moderate (Type 2) and Strict (Type 3) configurations to optimize incoming traffic for multiplayer gaming networks.
• OpenVPN drivers – Selects between TUN (network bridge for optimized speed performance) and TAP (network adapter mode for specific virtualized environments).
• IPv6 leak protection – Forcefully disables IPv6 network traffic to prevent location-mapping leaks over unencrypted parallel connections.

Server network

A VPN’s server network can have a big impact on speed, coverage, and connection reliability. Proton VPN has built an impressive network of 20,600+ servers across 148 countries and 195+ locations, giving users plenty of options for connecting around the world.

Speed tests

Proton VPN delivers strong speeds thanks to its 10 Gbps physical server infrastructure and WireGuard support. On our 1 Gbps fiber connection, it reached a top speed of 698 Mbps.

Here’s how it performed across our main test locations:

Server location	Download speed
Seattle, USA	698 Mbps
London, UK	614 Mbps
Los Angeles, USA	582 Mbps
New York, USA	524 Mbps

To mitigate packet loss across complex routing legs, the provider incorporates a proprietary VPN Accelerator algorithm. This technology uses multi-threaded system processing and optimized TCP error recovery to sustain speeds over long-distance, overseas server connections.

Here’s how Proton VPN performed in our standard speed tests:

• Proton VPN connected to a server in Seattle, 698 Mbps:

• Proton VPN connected to a server in Los Angeles, 582 Mbps:

• Proton VPN connected to a server in New York, 524 Mbps:

• Finally, I tried an overseas connection which gave me a surprise, since the result was better than those for LA or NY. Proton VPN connected to a server in the UK, 614 Mbps:

Proton VPN also offers VPN Accelerator, which can improve speeds in certain situations. It uses techniques such as multi-threading and specialised TCP algorithms to process traffic more efficiently and recover faster from packet loss.

Secure Core

For users who want an extra layer of privacy, Proton VPN offers more than 120 Secure Core servers. The feature works like a Double VPN, routing your traffic through two separate physical servers before it reaches the internet.

The first server is physically owned and operated by Proton AG and located in a high-privacy jurisdiction such as Switzerland, Sweden, or Iceland. This helps add protection against traffic analysis and potential server compromise.

The trade-off is speed. Routing your traffic through two servers adds latency and can reduce connection speeds, so Secure Core is better suited to privacy-focused browsing than gaming or 4K streaming. For comparison, you can see how NordVPN and Surfshark approach multi-hop VPN connections in our detailed guide.

Swiss jurisdiction

Proton VPN is headquartered in Geneva, Switzerland, a country known for its strong privacy protections and its location outside the 5/9/14 Eyes surveillance alliances. Swiss jurisdiction gives Proton VPN a privacy-friendly legal backdrop and limits the scope of foreign data requests.

The service is also GDPR compliant and follows a strict no-logs policy backed by five consecutive annual independent audits by Securitum. Proton VPN says it does not store browsing activity, connection timestamps, or IP addresses. It does retain the timestamp of your most recent account connection, which is deleted when you log in again.

Founded by CERN and MIT scientists, Proton AG is primarily owned by the non-profit Proton Foundation.

Customer support

Proton VPN offers 24/7 live chat support through the account dashboard for paid subscribers, a welcome improvement over its previous limited hours.

Support includes:

• Knowledge base – Setup guides, troubleshooting help, and platform-specific instructions.
• Email support – Available for technical and billing issues, with responses typically arriving within 12 hours.
• In-app reporting – Lets you attach sanitised diagnostic logs when reporting bugs, helping Proton investigate issues faster.

Proton VPN’s Support Center offers setup guides, troubleshooting tips, and platform-specific help, covering most common questions. More specific issues may still require contacting support.

In my recent tests, most inquiries were answered the same day, which is a noticeable improvement from my earlier reviews, when responses sometimes took several days. Support has clearly improved in recent years.

Streaming capabilities

Proton VPN delivered smooth performance in our streaming tests, including 4K playback. It reliably unblocked Max without proxy errors and also worked with major Netflix libraries, including the US, UK, and Canada. Hulu, Disney+, Amazon Prime Video, and BBC iPlayer were also accessible.

Kill switch tests

Our stress tests confirmed that Proton VPN’s kill switch works as expected during sudden network drops. It immediately blocks internet traffic when the VPN connection is interrupted, helping prevent accidental exposure of your IP address or online data.

Reputation and reviews

Proton VPN has a 2.2/5 TrustScore on Trustpilot, with complaints mainly involving connection issues, slow free-tier servers, and billing disputes. That’s considerably lower than NordVPN (4.2/5) and Surfshark (4.3/5).

However, feedback elsewhere is more positive. Proton VPN averages around 4.5 stars across major tech publications and app stores, with users often praising its open-source apps, WireGuard speeds, clean interface, and strong privacy protections.

Competitor comparison

Proton VPN goes up against established names like NordVPN and Surfshark, but each takes a slightly different approach. Proton stands out for its Swiss privacy focus and free plan, while NordVPN puts more emphasis on speed and security features, and Surfshark focuses on affordability and unlimited connections.

	Proton VPN	NordVPN	Surfshark
Simultaneous connections	Up to 10 devices	Up to 10 devices	Unlimited
Security extras	Secure Core routing & NetShield ad blocker	Threat Protection Pro & Dark Web Monitor	CleanWeb ad blocker & Dynamic MultiHop
Server network scale	20,600+ servers across 148 countries	7,800+ servers across 126 countries	4,500+ servers across 100 countries
Truly free tier?	✅ Unlimited data, 5 locations	❌ Paid only	❌ Paid only

One of Proton VPN’s biggest differentiators is Secure Core, which routes traffic through hardened servers in privacy-friendly locations before sending it to the internet. It also offers a free plan with unlimited bandwidth, although the free tier is limited to servers in a small number of countries.

If you’re more interested in speed, advanced security features, and overall performance, see our full NordVPN review for a closer look at how it performs.

For lower pricing and unlimited simultaneous connections, our Surfshark review takes a deeper look at what makes it a strong option for households with lots of devices.

Conclusion

Proton VPN has come a long way and is now one of the strongest all-around VPNs available. Its expanded server network, fast WireGuard performance, and upgraded 24/7 support address several of the weaknesses we noted in earlier reviews. Add in Swiss jurisdiction, open-source apps, and multiple independent audits, and Proton VPN makes a compelling choice for both privacy-focused users and everyday streaming.
