Check it on your own connection
Records say what ExpressVPN and NordVPN state. A test shows what your own connection does today: run the ExpressVPN leak test with that app connected, or the NordVPN leak test with the other; each checks your IP, DNS, WebRTC and IPv6.
How this page is kept
- ExpressVPN’s column is read from expressvpn.com and github.com; NordVPN’s from nordvpn.com, support.nordvpn.com and sb.nordcdn.com. Auditors’ published reports count as well. Each cell links its source and the date it was read.
- “No statement on record” under ExpressVPN or NordVPN means our sources hold none for that provider. It is not a finding that ExpressVPN or NordVPN lacks the feature; check its own pages.
- This page does not rank ExpressVPN against NordVPN. Which row matters depends on what you need the VPN for.
- A script re-reads every ExpressVPN and NordVPN source weekly; when one changes, a person checks it before the ExpressVPN or NordVPN row changes. These records also feed every published VPN audit, who owns which VPN and leak issues by provider.
