Surveillance audit

A surveillance audit is the yearly audit a certification body performs between ISO certification audits to confirm the management system is still maintained.

An ISO 27001 certificate runs for three years, with surveillance audits in the years between the initial certification and recertification. A surveillance audit covers part of the system each time and can lead to suspension if major nonconformities are found.

See ISO 27001.
