ISO/IEC 27001:2022 requirements fall into two parts. First, the seven mandatory management-system clauses (4–10) that every certified organization must implement: context, leadership, planning, support, operation, performance evaluation, and improvement. Second, the 93 Annex A controls grouped into four themes — Organizational (37), People (8), Physical (14), and Technological (34) — from which you select applicable controls based on your risk assessment and document the result in a Statement of Applicability (SoA). The clauses are non-negotiable; the controls are risk-driven. Certification is awarded by an accredited certification body (such as TÜV SÜD, BSI, or DNV) after Stage 1 and Stage 2 audits — Tranquility Cybersecurity (TCSA) prepares your ISMS so it passes, but does not issue the certificate. See the standard at ISO/IEC 27001.

Frequently Asked Questions

ISO 27001:2022 requirements, clauses, and Annex A controls — answered.

Do I need to implement all 93 Annex A controls?

No. You select controls based on your risk assessment and document them in the Statement of Applicability (SoA), justifying any exclusions. Most organizations apply 70–85 controls depending on their risk profile and business context.

What is the difference between the clauses and the Annex A controls?

Clauses 4–10 are mandatory management-system requirements that define the ISMS framework (what you must do). Annex A controls are security measures you select based on your risk assessment (how you do it). All clauses are mandatory; Annex A controls are risk-based.

What are the mandatory documented information requirements?

ISO 27001:2022 requires the ISMS scope, information security policy, risk assessment methodology, risk assessment report, risk treatment plan, Statement of Applicability (SoA), internal audit programme, and management review records. Additional documentation depends on the Annex A controls you select.

Who issues the ISO 27001 certificate?

An accredited certification body — for example TÜV SÜD, BSI, or DNV — issues the certificate after a successful Stage 1 (documentation) and Stage 2 (implementation) audit. Tranquility Cybersecurity is the consultant that prepares your ISMS to pass; we are not the certification body and do not issue the certificate.

What changed in ISO 27001:2022 versus the 2013 version?

The 2022 revision reorganized Annex A from 14 categories (114 controls) into 4 themes (93 controls) and added 11 new controls covering cloud security, threat intelligence, data masking, web filtering, and secure coding. Clauses 4–10 remain largely unchanged.
