Smart ISO 27001 Preparation Starts Here

ISO 27001 certification has become a baseline requirement for B2B SaaS, fintech, and healthtech companies handling sensitive data. And for good reason: the global average cost of a data breach reached US$4.44 million in 2025, with regulatory non‑compliance and slow incident containment continuing to drive the highest losses. But achieving certification is rarely straightforward. Many companies struggle with unclear scoping, weak policies, undocumented assets, and rushed risk assessments – all of which can lead to failed audits and costly delays. This checklist was created to help you avoid those mistakes. It combines 11+ years of TechMagic’s experience implementing ISO 27001 into a clear roadmap for success. You’ll learn how to define your ISMS scope, structure your internal policies, conduct risk assessments using a proven matrix, and monitor controls.
