Organizations may be certified compliant with ISO/IEC 27001 by a number of accredited certification bodies worldwide. Certification against any of the recognized national variants of ISO/IEC 27001 (e.g. the Japanese version) by an accredited certification body is functionally equivalent to certification against ISO/IEC 27001 itself. Certification audits are usually conducted by ISO/IEC 27001 Lead Auditors.

In some countries, the bodies which verify conformity of management systems to specified standards are called "certification bodies", in others "registration bodies", "assessment and registration bodies", "certification/ registration bodies", and sometimes "registrars".

ISO/IEC 27001 certification usually involves a three-stage audit process:

Stage 1 is a "table top" review of the existence and completeness of key documentation such as the organization's security policy, Statement of Applicability (SoA) and Risk Treatment Plan (RTP).

Stage 2 is a detailed, in-depth audit involving testing the existence and effectiveness of the information security controls stated in the SoA and RTP, as well as their supporting documentation.

Stage 3 is a follow-up reassessment audit to confirm that a previously-certified organization remains in compliance with the standard. Certification maintenance involves periodic reviews and reassessments to confirm that the ISMS continues to operate as specified and intended.
