GRC (Governance, Risk, and Compliance) is a broad management discipline covering how an organisation directs strategy, manages risk, and meets regulatory obligations across all domains. An ISMS (Information Security Management System) is a specific implementation of governance and risk management focused on information security, typically conforming to ISO 27001. An ISMS is one component within a wider GRC programme. Acuna is a GRC platform that supports ISMS management as one of its use cases alongside privacy, business continuity, supplier risk, and enterprise risk management.
