Mullvad vs Proton VPN: Which Privacy Powerhouse Wins?

According to CNET’s 2025 VPN testing, Proton VPN delivered faster speeds with just 16% speed loss compared to Mullvad’s 24%, though both performed excellently given that typical VPNs can cut speeds by 50% or more. Mullvad costs a flat 5 euros monthly with no long-term commitments, while Proton VPN offers a legitimate free tier and paid plans starting at $60 for the first year then $80 annually. Proton VPN provides access to over 15,800 servers across 126 countries with up to 10 connections, while Mullvad offers about 700 servers in 50 countries with 5 simultaneous connections. Both services undergo regular audits and operate from privacy-friendly jurisdictions, with Proton based in Switzerland outside the 14-Eyes alliance. The key difference lies in their privacy approaches: Mullvad offers cutting-edge DAITA protection against AI traffic analysis and post-quantum encryption, while Proton focuses on full-disk encryption and its Stealth protocol for obfuscation.

The Privacy Philosophies

Here’s where things get really interesting. Mullvad takes this almost radical approach to privacy – they literally don’t want to know anything about you. No email required, no recurring subscriptions, just pure VPN service. Their DAITA feature is genuinely innovative – it basically makes all your data packets look identical by adding junk data, which completely scrambles any fingerprint that AI systems could use to identify your traffic patterns. That’s next-level privacy thinking.

Proton takes a different but equally valid approach. Instead of RAM-only servers that wipe on reboot, they use full-disk encryption so even if someone physically seizes their servers, they can’t read anything. And their Stealth protocol is specifically designed to defeat deep packet inspection, which is crucial if you’re dealing with restrictive networks or censorship.

Speed Reality Check

Now, about those speed numbers – 16% versus 24% sounds like a big difference, but here’s the thing: if you’ve got decent internet to begin with, you probably won’t notice either. Both are using WireGuard protocol, which is basically the gold standard for VPN speed these days. Proton’s VPN Accelerator feature claiming up to 400% speed boosts? I’m skeptical – the CNET tester didn’t notice much difference, and honestly, these “magic boost” features often feel more like marketing than reality.

But if you’re on shaky internet, Proton might actually help more because of that accelerator feature. For everyone else? Both are plenty fast for streaming, gaming, whatever you’re doing.

The macOS Problem

This is where Proton VPN has a serious issue they need to fix. When you switch servers on macOS, your connection breaks and your real IP gets exposed momentarily. The app only tells you “Not Connected” AFTER you’ve already initiated the switch. That’s just bad design – ExpressVPN and Surfshark warn you beforehand. For a service that markets itself to privacy-conscious users, this is a pretty glaring oversight. If you’re doing sensitive work on a Mac, you need to be aware of this limitation.

Free vs Flexible

Proton’s free VPN tier is legitimately the only free VPN worth considering – no bandwidth limits, same core privacy protections. But you’re limited to one connection and servers in just 10 countries. No streaming or torrenting either. Mullvad’s pricing model is beautifully simple – 5 euros whether you use it for a month or a decade. No surprise price hikes, no forgetting to cancel subscriptions. You’re in complete control.

And here’s the real question: do you need a full privacy suite or just a VPN? Proton offers email, calendar, storage – the whole package. Mullvad just does VPN, but they do it exceptionally well. According to their winter 2025-2026 roadmap, Proton is working on post-quantum encryption, though they’re being cautious about implementation – which honestly, is probably smart given how new this cryptography is.

Who Should Choose What

Basically, if you’re a privacy purist who wants the absolute latest in traffic obfuscation and you don’t care about streaming, Mullvad is your winner. Their no-information-collection policy and innovative DAITA protection are unmatched. But if you want strong privacy PLUS everyday usability – streaming, a huge server network, and that legit free tier – Proton VPN is probably your better bet. Just be careful on macOS.

Both are excellent choices, but they serve slightly different masters. One isn’t objectively better than the other – it’s about which philosophy and feature set matches your actual needs. And honestly, in a world full of sketchy VPN providers, having two genuinely trustworthy options is pretty refreshing.
