Mullvad - Key Strengths

  • Maximum account anonymity: Sign up with just an account number - No email, no name, no payment data linked to identity. Pay with cash sent by post or Monero.
  • Flat pricing removes the incentive to collect or retain user data for billing purposes.
  • All WireGuard key pairs are rotated automatically, preventing long-term IP mapping.
  • The 2023 police raid proved the no-logs policy technically rather than just legally - Officers left empty-handed.

ProtonVPN - Key Strengths

  • Swiss jurisdiction: Switzerland has not signed the CLOUD Act, and Swiss courts have a high bar for ordering data disclosure.
  • Free tier offers unlimited data with no bandwidth cap - The only reputable truly free VPN option.
  • Stealth protocol reliably bypasses censorship in China, Iran, and Russia.
  • Deep integration with Proton ecosystem: use the same account for Proton Mail (end-to-end encrypted email), Proton Drive, and Proton Pass (password manager).
  • Secure Core multi-hop routes traffic through privacy-friendly jurisdictions (Iceland, Switzerland) before exiting anywhere.
