ISO 27001
The international standard specifying requirements for establishing, implementing, maintaining, and continually improving an ISMS.
ISO/IEC 27001 is the world's leading international standard for information security management. Published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), it provides a systematic framework for managing sensitive company information so that it remains secure. The current version, ISO/IEC 27001:2022, includes a revised set of controls in Annex A.
The standard follows the "Plan-Do-Check-Act" (PDCA) improvement cycle and requires organizations to perform a risk assessment, define the scope of their ISMS, select applicable controls from Annex A, and document their approach in a Statement of Applicability (SoA). Compliance can be independently verified through an accredited certification audit, resulting in an ISO 27001 certificate valid for three years, subject to annual surveillance audits.
ISO 27001 certification is increasingly requested by enterprise customers, public sector clients, and regulated industries as evidence of a mature security posture. It is also recognized as a practical framework for meeting regulatory requirements such as NIS 2, DORA, and GDPR, making it a strategic asset for organizations seeking to demonstrate trustworthiness to stakeholders.
Legal Basis
ISO/IEC 27001:2022; EU Directive 2022/2555 (NIS 2); EU Regulation 2022/2554 (DORA)
Practical Example
A B2B SaaS provider wants to sell its software to enterprise customers in regulated industries. Several procurement processes require proof of ISO 27001 certification. The company scopes its ISMS around its cloud infrastructure and development processes, performs a risk assessment, implements controls from Annex A, and undergoes a two-stage certification audit with an accredited body. After successfully passing the audit, the certificate opens new business opportunities and simplifies customer due diligence.
