What is No-logs audit?

A VPN no-logs claim is a promise that browsing data is not stored. A no-logs audit is an outside firm's review of that promise, so the auditor and the year carry the weight. Amnezia VPN lists its checks under 7A Security, audits 2022, 2024 and 2025, and AzireVPN lists X41 D-Sec, 2026. Betternet names Pango. Brave Search points to software and infrastructure audits from Assured AB and the Guardian. BullGuard does not have an audit of its own, and the network it uses carries a separate outside audit.
