No identifying information versus no compromise on speed: that is the choice facing privacy-conscious internet users in 2026. Mullvad VPN and ProtonVPN have emerged as the two names analysts and privacy advocates cite most often, yet they have built fundamentally different answers to the question of what a privacy tool should actually do.
Anonymity by design versus accountability by audit
Mullvad's approach is architectural rather than promissory. Signing up generates a random 16-digit account number - no email, no name, no username. Pay with cash mailed to the company's Gothenburg office, or with Bitcoin or Monero, and no billing trail ever connects to the account. Under a legal order, Mullvad has nothing to hand over beyond a number and a credit balance, because nothing else exists. That is a structural guarantee, not a policy choice that could change with new management or new pressure.
ProtonVPN takes the opposite route: transparency through verification. Email registration is required, but the company, Proton AG, has built a public record of independent scrutiny - five consecutive annual audits by the security firm Securitum between 2022 and 2026, along with a SOC 2 Type II attestation. A Swiss court case in 2021 involving Proton Mail, not ProtonVPN, showed the limits of this model: an identity record existed and was disclosed, even though VPN session data itself remained inaccessible to the company. For users whose threat model centers on state-level surveillance and metadata correlation, that distinction matters.
Network reach, speed, and the cost of going lean
The infrastructure gap between the two services is the starkest in the comparison. ProtonVPN's server count grew from roughly 15,800 across 126 countries in late 2025 to more than 20,000 servers in over 140 countries by October 2026 - a footprint that rivals the largest commercial VPN networks anywhere. Mullvad moved the opposite direction. After retiring OpenVPN entirely on January 15, 2026, to become a WireGuard-only service, its server count fell to 582 machines across 50 countries, down from roughly 700 the year before. Every one of those servers is a physical machine; Mullvad deliberately avoids virtual servers, while a meaningful share of ProtonVPN's network uses virtual locations, clearly labeled in its apps, where the exit IP's registered country differs from the server's physical location.
That infrastructure difference shows up in independent speed testing. ProtonVPN averaged a 16 percent speed reduction from baseline across 2025-2026 tests, placing it among the fastest premium VPNs available. Mullvad averaged 24 percent - respectable, but behind the leaders. Latency results split by region: Mullvad edged ahead on UK servers, but ProtonVPN won consistently on US, Australian, and Japanese connections, a practical advantage for most North American users. Both rely on WireGuard as their primary protocol, so the gap reflects routing and server-management quality rather than any underlying technical disadvantage.
Pricing, free tiers, and the Secure Core answer
Mullvad's pricing has not changed since the company launched in 2009: a flat €5 per month, no annual discount, no tiers, no upsell. ProtonVPN runs a conventional structure - a genuinely useful free tier with unlimited bandwidth but only one connection and no streaming access, and a Plus plan priced around $10 monthly, $60 annually, or $108 across two years, with promotional pricing fluctuating through the year. At two-year billing, ProtonVPN comes out cheaper per year; Mullvad compensates with total billing flexibility and the option to stay fully anonymous in payment as well as identity.
ProtonVPN also offers Secure Core, a double-hop system that routes traffic through hardened servers in Switzerland, Iceland, and Sweden before it reaches the exit node - protection against a compromised exit server that Mullvad's own multi-hop WireGuard configuration does not replicate with dedicated entry infrastructure. It is one more sign of how differently these two companies have chosen to define the same word: privacy.
