ISO/IEC 27001 Certification

ISO/IEC 27001 is the internationally recognized standard for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS), published jointly by the International Organization for Standardization and the International Electrotechnical Commission. The 2022 revision (ISO/IEC 27001:2022) restructured the Annex A controls from 114 controls across 14 domains to 93 controls organized into 4 themes: Organizational (37 controls), People (8 controls), Physical (14 controls), and Technological (34 controls), adding 11 new controls addressing areas such as threat intelligence, cloud security, ICT readiness for business continuity, and data masking. Certification requires a two-stage audit conducted by an accredited certification body: Stage 1 evaluates ISMS documentation, scope definition, risk assessment methodology, and Statement of Applicability (SoA) readiness; Stage 2 verifies implementation effectiveness through evidence review, interviews, and on-site observation. The certification cycle spans three years — after initial certification, organizations undergo annual surveillance audits in years two and three, followed by a full recertification audit. Total certification costs range from $20,000 to $100,000 or more depending on organization size, number of locations, ISMS scope, and the certification body selected, with ongoing annual surveillance audits costing $10,000 to $40,000. Implementation timelines typically span 6 to 14 months for organizations starting from scratch, though those with existing SOC 2 programs can accelerate to 3 to 6 months by leveraging control overlap. ISO 27001 is often pursued alongside SOC 2 for organizations serving both international and U.S. enterprise markets, as it satisfies regulatory requirements in the EU, UK, and Asia-Pacific regions where SOC 2 carries less recognition.
