ISO 27001 Compliance Doesn’t Guarantee Operational Security

ISO 27001 compliance can create a false sense of security in manufacturing when certification is driven by policies, risk registers, and audit artifacts rather than operational validation. In this blog, we explain where the security gap forms, why certified manufacturers still fail to prevent real attacks, and how to bridge compliance to resilience using OT security guidance from NIST SP 800-82 and industrial security practices embedded in ISA/IEC 62443.
