FAQ

ISO 27001: frequently asked questions

What is the difference between ISO 27001 and ISO 27701?

ISO/IEC 27001 covers information security management. ISO/IEC 27701 covers privacy information management (PIMS). Since the 2025 edition, ISO/IEC 27701 can be implemented as a standalone management system as well as alongside ISO/IEC 27001.

How many controls are in ISO 27001:2022?

ISO 27001:2022 Annex A contains 93 controls organized into 4 themes: Organizational, People, Physical, and Technological.

Who issues the ISO 27001 certificate?

Certificates are issued by an independent certification body after its own stage 1 and stage 2 audits. Certsure Certification is a consultancy: we prepare your organisation — gap analysis, documentation, training, internal audit and audit support — and coordinate with an accredited certification body. You can verify accredited certificates on IAF CertSearch.

How long is ISO 27001 certification valid?

Accredited management system certificates are normally valid for three years, with surveillance audits by the certification body at least once a year and a recertification audit before expiry.

How much does ISO 27001 certification cost?

Cost depends mainly on the number of employees and sites, the scope and complexity of your activities, how much of the system already exists, and the certification body's audit days.
