ISO 27001 - Information Security
The leading international standard for information security management and cybersecurity
ISO/IEC 27001:2022 is the leading international standard for Information Security Management Systems (ISMS). It defines the requirements for establishing, implementing, maintaining, and continually improving an ISMS.
The latest 2022 edition includes 93 controls organized into four themes: organizational, people, physical, and technological. Transition from the 2013 edition must be completed by October 31, 2025.
In Greece, ISO 27001 certification is gaining critical importance due to NIS-2 (Law 5160/2024) requiring cybersecurity measures from essential and important entities. Certification is the most reliable way to demonstrate compliance.
The certification process involves three stages: preliminary documentation review, detailed compliance audit, and surveillance audits.
Who is this for
ISO 27001 is aimed at technology and IT companies, financial institutions, healthcare organizations, public bodies, e-commerce companies, cloud providers, telecommunications companies, and any organization processing sensitive data. Particularly important for entities subject to the NIS-2 directive.
