FAQ
What counts as an independent VPN audit?
Credible audits are conducted by recognised security firms — Deloitte, KPMG, Cure53, Securitum — with published reports. Self-assessments or vague 'security reviews' without a firm name score lower in our ethics category.
Does an audit guarantee no logging?
No audit can prove future behaviour, but it verifies configuration and policy at audit time. Prefer providers with annual or recurring audits and RAM-only server architecture.
Which cheap VPNs have independent audits?
Surfshark (Deloitte) and Proton free tier (Securitum) offer audited options under $3/mo. Ivacy and many ultra-cheap VPNs lack published independent audits — we penalise that in scoring.
