Proton VPN Review 2026: The Privacy-First VPN With a Real Free Tier

Proton VPN occupies a unique corner of the VPN market: it is the only major service built by a company whose other products — encrypted email, calendar, drive, and password manager — are the main event, with the VPN as one piece of a larger privacy ecosystem. That heritage shows up in the product in ways that matter, from an audited open-source codebase to a genuinely free tier with no data caps. The question is whether that trust-first approach holds up when you just want a fast, cheap VPN.

Proton VPN at a glance

Proton VPN is a Swiss-based VPN operated by Proton AG, the same company behind Proton Mail. It offers a truly free tier with unlimited data, plus two paid tiers — VPN Plus and Proton Unlimited — with access to a very large server network spanning over 145 countries and support for up to 10 simultaneous devices. Its apps are open source and independently audited, and the company operates under Switzerland’s strong privacy laws.

Pros

• Genuinely free tier with unlimited data and no ads — rare among reputable VPNs
• Swiss jurisdiction with strict privacy laws and a track record of resisting data requests
• Open-source, independently audited apps
• Very large server network (tens of thousands of servers, 145+ countries)
• Secure Core, NetShield, and Stealth protocol for advanced privacy and censorship resistance

Cons

• The free tier limits you to one device and random server selection
• Speeds can dip during peak hours on the free and lower tiers
• Proton Unlimited’s value only materializes if you actually use the bundled email, drive, and calendar
• No live chat support — ticketing and knowledge base only

What is Proton VPN?

Proton VPN started as a side project of Proton Mail, the encrypted-email pioneer, and that origin still defines its philosophy: build privacy tools that are open source, audited, and run from a jurisdiction where the law favors the user. The VPN itself does what all VPNs do — encrypts traffic and hides your IP — but it layers on several features most competitors reserve for higher tiers or skip entirely. NetShield blocks ads, trackers, and malware at the DNS level on every paid plan. Secure Core routes your traffic through privacy-friendly countries before it exits to its destination, protecting against compromised exit servers. And the Stealth protocol is designed specifically to hide the fact that you are using a VPN at all, which matters in countries that actively block VPN traffic.

The other defining feature is the free tier. Unlike the truncated trials most VPNs offer, Proton VPN’s free plan has no data cap, no ads, and no time limit — it restricts you to one device and a limited set of countries, but it is a real product rather than a marketing hook. For privacy-first users comparing Proton’s approach to a dedicated encrypted-storage service, Internxt is a useful adjacent comparison, since both build zero-knowledge privacy into their architecture.

Proton VPN plans and pricing

Proton VPN sells two paid tiers on top of its free plan, each available monthly, yearly, or on a two-year term. As with every VPN, the advertised price is the introductory rate, and the two-year plan is where the real discount sits. The free tier is worth calling out separately because it is one of the few genuinely usable free VPNs available.

Plan	1-month	1-year (per month)	2-year (per month)
Free	$0	$0	$0
VPN Plus	$9.99	$3.99	$2.99
Unlimited	$12.99	$9.99	$7.99

VPN Plus is the core VPN product: the full server network, 10 simultaneous devices, NetShield, Secure Core, streaming and P2P support, and the fastest servers Proton offers. Proton Unlimited takes everything in VPN Plus and adds the rest of the Proton ecosystem — Proton Mail with 500 GB of storage and 15 addresses, Proton Drive, Proton Calendar, and Proton Pass — which makes it the better deal only if you would otherwise pay for those services separately. For most people who just want a VPN, VPN Plus at $2.99 a month on the two-year plan is the sweet spot.

Core features

Secure Core

Secure Core is Proton’s answer to the risk of compromised exit servers. Instead of routing your traffic directly to its destination, it first passes through hardened, privacy-friendly servers in Switzerland, Iceland, or Sweden before exiting to the wider network. Even if an attacker controlled the final exit server, they would see only the Secure Core IP, never your real one. It is a feature aimed squarely at journalists, activists, and anyone whose threat model includes a hostile network.

NetShield

NetShield filters DNS requests to block ads, trackers, and known-malicious domains before they reach your device. It runs on every paid plan and is configurable — you can block only malware, or tighten it to include ads and trackers depending on how aggressively you want to filter.

Stealth protocol

The Stealth protocol obfuscates VPN traffic so that it does not look like VPN traffic to deep-packet inspection, which is how restrictive countries and networks block VPNs. Combined with WireGuard, OpenVPN, and IKEv2 support, it gives Proton one of the broadest protocol lineups of any provider, and it is a real advantage for anyone connecting from a censored region.

Proton ecosystem

The Unlimited tier ties the VPN into Proton Mail, Proton Drive (500 GB), Proton Calendar, and Proton Pass. For someone already living in the Proton ecosystem, it replaces several subscriptions; for everyone else, it is a bundle you would be paying extra for without using.

Security and privacy

Proton is based in Switzerland, which sits outside the Five Eyes and Fourteen Eyes intelligence-sharing alliances and has some of the strongest data-protection laws in the world. The company’s no-logs policy has been independently audited, its apps are open source so anyone can inspect the code, and its parent company has a documented history of fighting data requests in court — including a landmark case at the Swiss Federal Supreme Court that clarified the limits of VPN logging obligations. That legal and technical track record is the strongest argument for choosing Proton over a provider whose privacy claims rest on marketing alone.

Speed and performance

Proton VPN’s paid tiers are fast, with support for WireGuard and servers spread across more than 145 countries. The network is one of the largest of any provider, which means you are rarely forced onto a distant, congested server. The free tier is intentionally rate-limited to medium speeds, so it is fine for casual browsing but not ideal for streaming or large downloads. For a security-suite comparison that includes antivirus alongside VPN features, F-Secure’s review is a useful reference point if you are weighing a bundled antivirus against Proton’s privacy-first approach.

Streaming and device support

Proton VPN reliably unblocks streaming services including Netflix, and it supports P2P and torrenting on dedicated servers, with port forwarding available on paid plans. Apps cover Windows, macOS, Linux, Android, iOS, and routers, and a single paid account protects up to 10 devices at once. The interface is clean but slightly more technical than ExpressVPN’s — privacy power users will feel at home, complete beginners may need a moment to find their way around.

Who should use Proton VPN

Proton VPN is the right pick if you want a privacy-first VPN from a company with a legal and technical track record to back its claims, and especially if you will actually use the free tier or the broader Proton ecosystem. It is less ideal if you want the absolute fastest experience without any speed throttling on the free plan, or if you need phone or live-chat support rather than ticketing. Its free tier also makes it the obvious first stop for anyone who wants a trustworthy VPN without paying anything at all.

Frequently asked questions

Is Proton VPN really free?

Yes. The free plan has no data cap, no ads, and no time limit, and it does not require a credit card. It limits you to one device and a randomly selected server from a small country list, but it is a genuinely usable product rather than a trial.

How much does Proton VPN cost?

VPN Plus runs $9.99 monthly, $3.99 a month on the yearly plan, or $2.99 a month on the two-year plan. Proton Unlimited is $12.99 monthly, $9.99 yearly, or $7.99 on the two-year plan. Both paid tiers include a 30-day money-back guarantee.

How many devices can I connect at once?

Up to 10 simultaneous devices on any paid plan. The free plan allows one device at a time.

Does Proton VPN keep logs?

No. Proton VPN maintains a strict no-logs policy that has been independently audited, and it operates under Swiss privacy law, which is among the strongest in the world.

Is Proton VPN good for streaming and torrenting?

Yes. It reliably unblocks Netflix and other streaming services, supports P2P and torrenting on dedicated servers, and offers port forwarding on paid plans.

What does Proton Unlimited add over VPN Plus?

Proton Unlimited bundles the full VPN Plus feature set with Proton Mail (500 GB, 15 addresses), Proton Drive, Proton Calendar, and Proton Pass. It only makes financial sense if you will use those services rather than paying for them separately.

Final verdict

Proton VPN is the strongest privacy-first option in the VPN market. A genuinely free tier, Swiss jurisdiction, an audited open-source codebase, and a huge server network add up to a service that is both trustworthy and capable. The main reasons to look elsewhere are performance on the free tier and the fact that Proton Unlimited’s value depends on buying into the whole Proton ecosystem. If you want a VPN you can recommend without caveats about logging, and you do not mind a slightly more technical interface, Proton VPN is the one to beat — and its free tier is the easiest way to try it before paying.
