Information Security Management (ISO/IEC 27001) Certification

ISO/IEC 27001 defines information security management system (ISMS) requirements to protect the confidentiality, integrity and availability of information. It is risk-based: the organisation assesses its own assets and threats, and documents which controls from Annex A it will apply, together with the rationale, in a Statement of Applicability (SoA). The current version is ISO/IEC 27001:2022, and Annex A contains 93 controls under four themes.

• Software, SaaS and cloud service providers
• Finance, healthcare and e-commerce organisations processing customer data
• Suppliers required to answer enterprise customers' security questionnaires (vendor assessment)
• Organisations providing critical infrastructure and public services
• Data controllers required to evidence their technical and organisational measures under KVKK/GDPR

Generally not mandatory; there are sector exceptions. The main driver in practice is contractual: major enterprise buyers require an ISO/IEC 27001 certificate from their suppliers. KVKK and GDPR do not impose a certification requirement but require appropriate technical and organisational measures; the certificate is used as evidence of these measures.

• Clauses 4-10 — ISMS requirements: context, leadership, planning, support, operation, performance evaluation, improvement
• The risk-assessment and risk-treatment process; the Statement of Applicability (SoA)
• Annex A / Theme 1 — Organisational controls (37 controls): policies, roles, asset management, supplier relationships, incident management, continuity, compliance
• Annex A / Theme 2 — People controls (8 controls): screening, terms of employment, awareness and training, disciplinary process, remote working
• Annex A / Theme 3 — Physical controls (14 controls): secure areas, entry control, equipment security, clear desk
• Annex A / Theme 4 — Technological controls (34 controls): endpoint security, privileged access, cryptography, logging, vulnerability management, network security, secure development, data-leakage prevention

1. 1ApplicationThe organisation's field of activity, headcount, number of sites and scope boundaries are determined. The number of audit days is calculated from this information.
2. 2Document Review (Stage 1)The management system documentation, scope definition, risk assessment and internal-audit/management-review records are examined; readiness for the on-site audit is assessed.
3. 3Certification Audit (Stage 2)It is verified on site that the system is implemented and effective. Findings are classified as major/minor nonconformity or observation.
4. 4Closing NonconformitiesThe organisation submits a root-cause analysis and corrective action plan. The certificate is not issued until major nonconformities are closed.
5. 5Issuing the CertificateThe certificate is issued after review by an independent decision-maker. The audit team cannot make the certification decision.
6. 6Surveillance AuditsA surveillance audit is carried out at least once a year during the certificate's validity. The first surveillance cannot exceed 12 months from the last day of Stage 2.
7. 7RecertificationAt the end of three years, the entire system is re-audited; it must be completed before the certificate expires.

Management system certificates are valid for three years. At least one surveillance audit is carried out per year during this period; the certificate is suspended if surveillance is not carried out. A recertification audit is completed at the end of the third year.

• Trade registry record and operating licence
• The organisation's organisation chart and headcount
• The list of sites/branches within scope
• The management system manual or process documentation
• Internal audit and management review records
• Legal permits, licences and operating documents, if any

There is no fixed list price; the cost is calculated based on the following variables and provided in writing in the quote.

• The headcount within scope (directly determines the number of audit days)
• The number of sites and branches; whether multi-site sampling applies
• The activity's risk level and process complexity
• The number of standards to be certified — an integrated audit reduces the number of days
• The three-year cycle: certification + two surveillance audits

Management system certification is carried out within the scope of ISO/IEC 17021-1. The certification body is accredited by an accreditation body party to the IAF multilateral recognition agreement (IAF MLA); This agreement establishes a chain of international recognition that ensures that a document issued in one country is accepted in other countries. EUROLAB has internationally recognized accreditation from IAF member accreditation bodies within the scope of ISO/IEC 17021-1.

The scope under which this scheme can be offered varies according to your product and activity; it is confirmed in writing at the quote stage.
