What is ISO 27001?

ISO/IEC 27001 specifies requirements for an information security management system (ISMS): a risk-based way of deciding which security controls an organisation needs, implementing them and keeping them effective. The certificate covers a defined scope, and the Statement of Applicability records which Annex A controls apply and why.

The current edition is ISO/IEC 27001:2022, amended in 2024 for climate change. Annex A was restructured into 93 controls in four themes, organisational, people, physical and technological, with new controls such as threat intelligence, information security for cloud services, data leakage prevention and secure coding. The transition period for certificates against the 2013 edition has ended.

For SaaS companies, data centres, BPO providers and fintechs, ISO 27001 is often the first item on a customer's security questionnaire. A certificate from an accredited body, verifiable in a public register, shortens that conversation.

Who it is for

  • SaaS and cloud service providers
  • IT services, managed services and BPO companies
  • Banks, payment companies and fintechs
  • Data centres and hosting providers
  • Health technology firms and health data processors
  • Suppliers handling government information

What sets audit time and cost

Most organisations reach a certification decision ten to sixteen weeks after application, often with a short gap between Stage 1 and Stage 2 to resolve documentation findings and build operating evidence.

  • Number of people working within the ISMS scope
  • Business and IT complexity, assessed under ISO/IEC 27006-1
  • Number of sites, including data centres and remote working
  • Extent of outsourcing to cloud and other suppliers
  • Sensitivity of information handled, such as payment or health data
  • Combined audits with ISO/IEC 27701 or ISO 22301

Why it matters

What ISO 27001 gives you

  1. 01

    Shorter security reviews

    An accredited certificate answers many customer due diligence questions in one document that the customer can verify independently.

  2. 02

    Controls chosen by risk

    Security spending follows an assessed risk picture rather than a checklist, and unused controls are excluded with a recorded reason.

  3. 03

    Clear accountability

    Named owners for risks and controls, with management review, make security a governed business process rather than an IT task.

  4. 04

    Room to extend

    ISO/IEC 27701 for privacy and ISO/IEC 42001 for AI build on the same management system and can be audited alongside it.

The audit

What our auditors examine

  1. 01

    Scope and context

    Whether the ISMS scope, its interfaces and its dependencies on suppliers are defined clearly and match what you tell customers.

  2. 02

    Risk assessment and treatment

    A repeatable method with defined criteria, identified risk owners and a treatment plan approved by them.

  3. 03

    Statement of Applicability

    How each Annex A control was included or excluded, and the trace back to risk treatment.

  4. 04

    Controls in operation

    Evidence that controls run: access reviews, supplier assessments, logging and monitoring, backups, vulnerability management, secure development and incident handling.

  5. 05

    Performance evaluation

    Measurement of security objectives, an internal audit programme and management reviews that act on the results.

  6. 06

    Planning of changes

    Changes to the ISMS planned and carried out in a controlled way, a requirement added in the 2022 edition.

How certification works

Every accredited certificate follows the same three-year cycle, with each step recorded and the result published in our register.

  1. 01

    Application and quote

    Tell us your scope, sites and headcount. We calculate audit time under the accreditation rules and send a fixed quote and audit plan.

  2. 02

    Stage 1 audit

    We review your documented management system, scope and readiness, and agree the Stage 2 plan. Any gaps are reported so you can close them first.

  3. 03

    Stage 2 audit

    Auditors check that the system works in practice: interviews, records and observation across the scope. Nonconformities are raised in writing.

  4. 04

    Certification decision

    Once corrective actions are accepted, a reviewer who did not take part in the audit makes the decision. Your certificate is issued and listed in the public register.

  5. 05

    Surveillance audits

    Shorter audits in the first and second years after certification confirm the system is maintained and improving. The register shows your current status throughout.

  6. 06

    Recertification

    Before the three-year certificate expires, a recertification audit reviews the whole system and renews the certificate for another cycle.

ISO 27001 questions

We audit; we do not consult.

To keep certification independent, we never design, build or fix the systems we audit, and decisions are made by people who did not take part in the audit. Read our impartiality policy.
