Pros and cons

Pros

  • No-logs claims are audited rather than asserted: Securitum's audit (Securitum, 2026) sits behind a No activity logs policy.
  • Free limits come with no caps on data or speed, no ads and no time limit.
  • 10 simultaneous devices, above the ranked VPN median of 8.
  • Servers in from 140 countries, with streaming for Netflix, Hulu and Disney+ and WireGuard and OpenVPN as the connection protocols.
  • A single account carries the VPN, a passkey vault with end-to-end encryption and 5 GB of free storage, with GDPR, HIPAA and ISO 27001 compliance reported.

Cons

  • Support runs on email, chat and help centre, and there is no phone line among them.
  • The free plan limits put you on a single device at medium speed with randomly selected countries, so constant use points at a paid plan.
  • End-to-end encryption is marketed for Proton for Business, while the consumer plan encrypts only the connection from your device to Proton's servers.
  • The plan set is aimed at business buyers, so a home user ends up paying for features built around teams.

Scored 9.3 / 10 by ShieldCue.

Who it suits

  • Readers who want a VPN, a passkey vault and encrypted storage under a single account instead of separate subscriptions.
  • Families sharing storage, since Pass Family covers several users and Pass Plus seats through a single admin panel.
  • Teams buying under a business audience (business) who need GDPR, HIPAA and ISO 27001 certifications on file.

Who should look elsewhere

  • Anyone needing more devices on a single account: Proton covers 10, while ESET Brasil plans run 3 to 25 devices.
  • Readers choosing purely on server spread: AVG lists from 100 countries, a base close to Proton's from 140.
  • Readers who want a different audit trail to compare: Session Technology Foundation lists Quarkslab 2021 against Proton's Securitum, 2026.

Core features

Proton VPN pairs servers in from 140 countries with 10 simultaneous devices. Connections run over WireGuard and OpenVPN, the feature set covers kill switch and split tunnelling so a kill switch and split tunnelling are standard, and streaming is supported for Netflix, Hulu and Disney+. Apps are published for Windows, macOS and Linux, which covers phones, desktops, streaming boxes and browser extensions alike.

Where it runs

Apps cover Windows, macOS and Linux, so phones, desktops, streaming boxes and browser extensions are all in scope. A paid account connects 10 devices at once under the same login, and the free tier allows a single device.

What you get free

A free plan is listed, and its limits are the forgiving kind: no caps on data or speed, no ads and no time limit. It runs on a single device, connects to servers in a randomly selected group of countries and delivers medium speed, so it works as a starting point rather than a full-time tunnel. Paid subscriptions come with a 30-day money-back window.

Protection features

Compliance reported for the suite covers GDPR, HIPAA and ISO 27001. Vault encryption is end-to-end, with keys held away from the provider, using AES-GCM vaults and OpenPGP for vault keys, and Proton states that its security claims are independently audited by third-party experts whose reports are public.

The company behind it

Proton VPN is run by Proton AG, founded in 2014 and based in Switzerland. Support runs on email, chat and help centre, which is written and self-service throughout rather than phone-based.

Frequently asked questions

What does Proton VPN cost, and how long are the commitments?+

The longest plan runs 24 months, the service is listed on a free model, and paid plans carry a 30-day money-back window. Across the ranked VPN field, monthly pricing has a median of €7.02 and long-term pricing a median of €3.97, which frames any quote you see.

Is there a free plan, and what are its limits?+

Yes. The free plan has no caps on data or speed, no ads and no time limit. It runs on a single device, reaches servers in a randomly selected group of countries and delivers medium speed, so the paid tier, which covers 10 devices, is the practical step for constant use.

Which devices and platforms does it cover?+

Apps cover Windows, macOS and Linux, and a paid account connects 10 devices at the same time. That allowance is a single figure across every platform, so a household running a phone, a laptop and a streaming box on the same login still fits inside the cap.

Where is Proton based, and how wide is the network?+

The service is based in Switzerland and registered in Switzerland, with servers in from 140 countries. Proton was founded in 2014 and is run by Proton AG, so the company behind the tunnel is named rather than anonymous.

Does it handle streaming, and can I split traffic?+

Streaming is supported for Netflix, Hulu and Disney+, and the listed features are kill switch and split tunnelling, so a kill switch and split tunnelling are part of the toolkit. Connections run over WireGuard and OpenVPN, which covers the mainstream choices.

What comes with the account beyond the VPN?+

Beyond the VPN, the account carries a passkey vault and encrypted storage: passkeys are supported, vault encryption is end-to-end with keys the provider never holds, and free storage starts at 5 GB. Compliance reported across the suite covers GDPR, HIPAA and ISO 27001, and Pass Family shares vaults and Pass Plus seats through a single admin panel.

How do I get help if a connection fails?+

Support runs on email, chat and help centre: email, chat, a help centre and a community forum. There is no phone line in that list, so urgent problems go through chat or written help, and the kill switch in kill switch and split tunnelling is the tool for dropping a connection that fails.
