ISO 27001

ISO 27001 provides a systematic approach to managing sensitive company information, ensuring it remains secure. The standard encompasses people, processes, and technology, and covers all types of organizations regardless of size, type, or nature. Certification is granted by accredited third-party auditors and demonstrates to customers, partners, and regulators that an organization takes information security seriously.

The standard is structured around a risk-based approach. Organizations must identify information security risks, select appropriate controls to address those risks, and implement a management framework to ensure the controls remain effective over time. Annex A of the standard provides a reference set of 93 controls (in the 2022 revision) organized across four themes: organizational, people, physical, and technological.

Achieving ISO 27001 certification involves several stages. First, the organization implements its ISMS and operates it for a period. Then, a Stage 1 audit reviews the ISMS documentation and readiness. A Stage 2 audit evaluates the actual implementation and effectiveness of the ISMS. Once certified, the organization undergoes annual surveillance audits and a full recertification audit every three years.

ISO 27001 is widely recognized globally and often serves as a baseline for regulatory compliance efforts. It aligns well with other frameworks such as SOC 2, NIST CSF, and GDPR, making it a strategic foundation for organizations managing multiple compliance obligations.
