ISO/IEC 27001:2022 is the international standard for an information security management system (ISMS).
It requires an organization to define the scope of its ISMS, assess information security risks, choose and justify controls from Annex A (93 controls in four themes: organizational, people, physical and technological), implement them, measure performance, audit itself and improve.
The 2022 edition replaced the 2013 edition; the IAF transition deadline was October 31, 2025, after which 2013 certificates are no longer valid. Amendment 1 (February 2024) added a requirement to consider whether climate change is a relevant issue for the ISMS.
Certification depends on documented information. The standard names the documents that must exist: ISMS scope, information security policy, risk assessment and risk treatment process and results, Statement of Applicability, security objectives, evidence of competence, operational planning records, monitoring results, internal audit program and results, management review outputs, and nonconformity and corrective action records.
Annex A adds topic-specific policies (access control, acceptable use, supplier security, secure development, backup, logging and more).

Voluntary. Adopted by organizations of any size or sector when customers, tenders or regulators ask for a certified ISMS. Some laws and sector schemes reference it as evidence of appropriate security, but certification itself is not legally mandated in most jurisdictions.

How it works
Every document is approved by someone other than its author, versioned, distributed to the people it covers and acknowledged by name. Sign it where a signature is what the standard wants, send a set out together as a package, and export a dated record of who read which version when an assessor asks.
The written policies this standard turns on live here, with every version and every acknowledgment on the record.
A very large ecosystem: ISO 27001 consultancies, virtual CISO services and compliance automation platforms. They scope the ISMS, run the risk assessment, write policies and the Statement of Applicability, conduct internal audits and prepare for the Stage 1 and Stage 2 audits. The consultant cannot also be the certifying auditor.
