What Is ISO 27001 Certification?

ISO/IEC 27001:2022, known as ISO 27001, certification for Information Security Management Systems (ISMS) is a formal, independent confirmation that your organisation meets the requirements of the world’s most recognised information security standard. Developed by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), thousands of organisations globally are ISO 27001-certified.

Certification demonstrates that your ISMS:

  • Identifies, manages, and reduces information security risks
  • Protects sensitive information from loss, misuse, or unauthorised access
  • Is documented and structured in accordance with ISO 27001 requirements
  • Supports compliance with applicable data protection and information security obligations
  • Prioritises continual improvement

ISO 27001 certification is commonly required or preferred in public sector contracts, supply chains, and security-critical tenders, making it a powerful commercial advantage.
