What Hicomply recommends
In our experience, ISO 27001 Requirements: Clause 4 works best when it is maintained as living evidence inside the ISMS, not recreated before each audit. Keep ownership, approvals, and version history clear, then use automation to reuse the same evidence across ISO 27001 and related frameworks. See how that works in a platform tour.
