Proton VPN and Surfshark sit two-tenths of a point apart in our comparison: 4.3/5 against 4.1/5. Numbers that close usually mean “buy whichever is on sale.”

Not here. These two products want different things from life, and picking the wrong one means paying for strengths you’ll never use.

The two scores, decomposed

Proton VPN’s 4.3/5 is built on trust criteria: Swiss jurisdiction (5/5), a KPMG-audited and four-times Securitum-verified no-logs policy (5/5), open-source apps, and 5/5 speed. Its weak spot is glaring: 3/5 on streaming, with Variable ratings on Disney+, BBC iPlayer, Hulu and Peacock in our data.

Surfshark’s 4.1/5 is the inverse shape. Streaming at 4.5/5, speed at 5/5, unlimited simultaneous devices, the lowest price in the top tier, and a Cure53-audited no-logs policy on RAM-only servers. Its discounts: Netherlands jurisdiction (a Nine Eyes country, 4/5) and a bug bounty and transparency record a step behind Proton’s.

Same league, opposite builds.

Privacy and trust: Proton by a clear margin

Both providers clear the serious-VPN bar: audited no-logs, RAM-only or equivalent infrastructure, modern protocols. The difference is in degree.

Proton’s case is about as strong as the industry offers. Switzerland sits outside the EU and outside every intelligence-sharing alliance, and Swiss law currently cannot compel VPN providers to log user data. The apps are open source. The company publishes a transparency report and runs its entire business on the premise that paying customers, not data, fund development. Four consecutive annual no-logs audits is a cadence nobody else matches.

Surfshark is credible rather than exceptional here: Cure53 audited the no-logs policy, the servers are RAM-only, and there’s been no incident in the company’s history. But the Netherlands is a Nine Eyes member, and if your threat model includes governments requesting data through alliances, that matters. Our guide to Five Eyes, Nine Eyes and Fourteen Eyes explains how much weight to give this.

If privacy is the reason you’re buying: Proton, and it’s not a coin flip.

Streaming: Surfshark, and it’s not close either

Our streaming data tells a one-sided story. Surfshark rates Very Good on Netflix, Disney+, Prime Video, HBO Max and Peacock, with only BBC iPlayer dropping to Good. Proton rates Very Good on Netflix and then Variable on most of the rest.

Variable means exactly what it sounds like: works this week, blocked next week, try another server. For a casual Netflix user that’s tolerable. For someone who bought a VPN specifically to watch Disney+ from abroad or Peacock’s Premier League coverage, it’s the product failing at its job.

Surfshark also has the household argument: unlimited devices means the TV, two laptops and four phones all run through one $3.19/mo subscription. Proton caps its Plus plan at 10 devices, which is plenty for a person and tight for a family.

Speed, features and the daily experience

Both score 5/5 on speed in our tests, both default to WireGuard (Surfshark directly, Proton via its own implementation), and both include the modern feature set: kill switch, split tunneling, ad and tracker blocking (NetShield vs CleanWeb).

Differentiators worth knowing: Proton offers Secure Core, which routes your connection through hardened servers in Switzerland, Iceland or Sweden before exiting elsewhere, a real protection against compromised exit servers. It also bundles Tor over VPN. Surfshark counters with MultiHop, camouflage and NoBorders modes for restrictive networks, and an alternative ID generator.

Power-privacy features: Proton. Convenience features: Surfshark. Sensing the pattern yet?

Server networks and the map question

Surfshark operates a fleet of 3,200+ servers across 100 countries, one of the broadest maps in the industry, and every location supports its full feature set. Proton VPN’s network is smaller in raw count but denser where it matters to its audience: strong European coverage, the hardened Secure Core sites in Switzerland, Iceland and Sweden, and steady expansion into censored and underserved regions, including free servers placed deliberately for users in difficult countries.

For most buyers the map question reduces to two checks: is there a fast server near you (both pass everywhere that’s likely if you’re reading this), and is there a server in the country whose content you want? Surfshark’s 100-country spread wins the second check more often, one more way this product leans toward the streaming-and-unblocking buyer.

Apps and support, the daily-use texture

Both ship clean apps on Windows, macOS, Linux, iOS, Android and TVs, but the personalities persist. Surfshark’s apps optimize for one-tap simplicity, with the advanced toggles tucked away; its support runs 24/7 live chat, useful at midnight when iPlayer breaks. Proton’s apps expose more: protocol pickers, Secure Core toggles, NetShield levels, all open source and auditable, with support running through email and an extensive knowledge base rather than chat.

Neither approach is wrong. Surfshark feels like a consumer product, Proton like a privacy tool with a good interface. After a week, you stop noticing either, which is the real test.

Price: Surfshark wins the spreadsheet

Surfshark’s 1-year plan runs $3.19/mo ($38.28/year). Proton’s equivalent is $3.99/mo ($47.88/year). Both offer 30-day money-back guarantees. On the 2-year horizon, Surfshark’s $47.76 total against Proton’s $71.76 widens the gap further.

Add unlimited devices versus 10, and Surfshark simply delivers more units of VPN per dollar. What Proton sells for the difference is trust depth and its free tier, which remains the best in the industry (our free VPN guide covers it).

The edge cases that flip the decision

A few situations override the general advice. If you need a VPN that works in heavily censored countries, Proton’s Stealth protocol and its track record of maintaining access during shutdowns make it the safer bet, and its free tier means you can keep it installed as a backup at no cost.

If your household shares one subscription across many people, Surfshark’s unlimited devices isn’t just cheaper, it’s the only sane administration model: no counting slots, no kicking grandma’s tablet off the plan.

If you torrent regularly, both allow P2P, but Proton’s port forwarding support gives it a real edge for seeding, while Surfshark keeps things simpler but slower for that specific use.

And if you’re privacy-curious but commitment-shy, the asymmetry matters: Proton lets you start free forever, Surfshark asks for money on day one (refundable for 30 days). The path of least regret runs through Proton’s free tier, upgrading to whichever personality fits once you know your own usage.

Which one should you buy?

Buy Proton VPN if the VPN is a privacy tool first: you care about jurisdiction, you like open-source software, you want Secure Core between you and a hostile network, or you want to start free and upgrade later. Read our full Proton VPN review for the complete picture.

Buy Surfshark if the VPN is a streaming and household tool: multiple people, multiple devices, regular geo-unblocking, lowest cost. Our Surfshark review has the full test results.

Our verdict

Proton VPN wins on points, 4.3/5 to 4.1/5, and wins the privacy comparison by a wider margin than the scores suggest. But most people shopping in this price range are buying streaming and multi-device coverage, and there Surfshark is simply the better product. Privacy-first: Proton. Everything else: Surfshark. Both are honest products; the mistake is buying the wrong personality.
