The international standard for an information security management system.
ISO 27001 certifies that you run an information security management system (ISMS): a documented, risk-driven process for choosing and operating controls. Annex A lists 93 controls across organizational, people, physical, and technological themes. Certification comes from an accredited body after a two-stage audit.
These controls exist because the platform needs them to run safely. The crosswalk reads their signed evidence against ISO 27001. Where there is no evidence, the report says gap.
