SaaS adoption, embedded AI, AI agents, OAuth integrations, non-human identities, and SaaS-to-SaaS connections have converged into a single, interconnected enterprise risk surface. SaaS Security Posture Management (SSPM), built to address application configuration and identity hygiene, no longer gives organizations the unified visibility, risk management, threat detection, and remediation this expanded surface demands. What should organizations assess, in their own environment and in vendor solutions, to close this gap and govern SaaS and AI risk through one control plane? This Leadership Brief argues that visibility, identity, data exposure, and supply-chain risk management are now central to securing enterprise SaaS and AI environments, and it sets out the key areas organizations should evaluate against their own requirements and against vendor solutions.
