The standard

Overview

ISO 27001:2022 is the international standard for information security management systems. It sets management system requirements in clauses 4 to 10 and lists 93 controls in Annex A, grouped into organisational, people, physical and technological themes. Controls are selected on the basis of a documented risk assessment and recorded, with reasons for inclusion or exclusion, in a Statement of Applicability.

Certification shows that an independent assessor has tested the system against the standard: that risks have been identified and treated, that the selected controls are in place, and that performance is monitored and reviewed. It is commonly requested in supplier due diligence, security questionnaires and contracts involving personal or client data. It supports work on UK GDPR compliance but does not by itself demonstrate compliance.

UKCert assesses in two stages. Stage 1 examines scope, risk method, the Statement of Applicability and the mandatory records. Stage 2 tests the controls in operation and reports findings against the clause or control concerned.

Who this is for

  • Software and SaaS firms holding customer data
  • Managed service providers, hosting and data centre operators
  • Organisations processing personal data under UK GDPR
  • Suppliers to financial services, healthcare or government clients
  • Organisations repeatedly answering long security questionnaires

What it gives you

Why organisations certify

What a certified ISO 27001:2022 assessment gives you once the certificate is issued.

Answers due diligence

A current certificate and Statement of Applicability replace much of the evidence gathering that supplier security questionnaires demand, shortening procurement and vendor review cycles.

Risk decisions recorded

Every control is chosen against an identified risk, so security spending, exclusions and accepted risks can be explained to a board, a client or a regulator.

Incident readiness

The standard requires defined reporting, assessment, response and learning for security events, so incidents are handled by process rather than improvisation.

Access under control

Identity, privilege and authentication controls are defined and reviewed on a schedule, reducing the standing access that causes much avoidable data exposure.

Supply chain assurance

Supplier screening, contract clauses and monitoring of cloud and outsourced services are treated as security controls in their own right, not procurement formalities.

Supports data protection

The controls address much of what UK GDPR expects of technical and organisational measures, giving documented evidence for your accountability obligations.

Scope

What the assessment covers

The areas an assessor works through. Your final scope is confirmed in writing before any audit is booked.

  • Scope statement and asset inventory
  • Information security risk assessment and treatment plan
  • Statement of Applicability across 93 Annex A controls
  • Access control, identity and privileged access management
  • Cryptography and key management
  • Supplier and cloud service security controls
  • Security incident management and threat intelligence
  • ICT readiness for business continuity

How it runs

The assessment, stage by stage

From first enquiry to certificate. Each stage is agreed with you before it starts.

  1. Scope and quotation

    We agree what is in scope: legal entities, locations, services, systems and cloud platforms. Audit duration and the quotation follow from that scope and your headcount.

  2. Risk and gap review

    An optional review of your risk assessment, Statement of Applicability and control evidence before formal assessment, identifying gaps in the Annex A controls you have declared applicable.

  3. Stage 1 assessment

    We examine scope, risk method, the Statement of Applicability, policies and mandatory records, and confirm that internal audit and management review have taken place. Readiness gaps are reported in writing.

  4. Stage 2 assessment

    We test controls in operation, sampling access reviews, change and incident records, supplier agreements, monitoring output, backups and continuity tests against your Statement of Applicability.

  5. Certification decision

    Findings are closed with corrective action and supporting evidence. An independent reviewer then decides on certification, and the certificate names the agreed scope and runs for three years.

  6. Surveillance and renewal

    Surveillance audits during the cycle check the risk assessment, scope changes and control performance. A full recertification audit is carried out before the certificate expires.

Questions

ISO 27001:2022 — frequently asked

Anything here that does not cover your situation, put it to an assessor rather than guessing at it.

Ask a question

For a single-site organisation with a working information security management system, 10 to 16 weeks from engagement to certification decision is a realistic range. Building the system from scratch takes longer, usually three to six months of internal work, because risk assessment, policy approval, a full internal audit and a management review all have to be completed before Stage 2.

Three years from the certification decision, subject to surveillance audits during the cycle and recertification before expiry. The certificate names the scope and the version of the standard. Changes such as new sites, new services or a significant change of scope should be notified, so that the certificate continues to describe what you actually do.

No. UK law does not require ISO 27001. UK GDPR requires appropriate technical and organisational security measures but names no standard. Certification is usually a contractual requirement instead, particularly for suppliers to financial services, healthcare and government, and it is often used as evidence when demonstrating accountability under data protection law.

We sample rather than repeat the whole assessment. Risk assessment updates, the Statement of Applicability, internal audit, management review, security incidents, corrective actions and any scope changes are examined each time. Across the three-year cycle, all applicable Annex A controls and all sites within the certified scope are covered.

Annex A was restructured from 114 controls in 14 clauses to 93 controls in four themes: organisational, people, physical and technological. Eleven controls are new, including threat intelligence, cloud service security, data masking, data leakage prevention and secure coding. Clauses 4 to 10 changed only slightly. The transition period for 2013 certificates has closed, so assessment is against the 2022 version.

Certifying against more than one standard?

Where you hold several standards, shared clauses are assessed once in a combined visit rather than as separate audits. Talk it through with an assessor before you decide what ISO 27001:2022 should sit alongside.
