TL;DR: Autonomous copilots, AI-driven phishing, and cloud authentication abuse will make visibility and privilege control the defining security problems of the year, especially as agents surface sensitive data and attackers exploit legitimate services for persistence and access, according to Proofpoint’s 2026 predictions. The governance gap is no longer theoretical: AI systems are becoming identities that security teams must govern like any other high-risk actor.

By the numbers:
- Only 44% of organisations have implemented any policies to manage their AI agents, despite 92% agreeing that governing AI agents is critical to enterprise security.
- Systems with least-privileged AI access had a 17% incident rate vs 76% for over-privileged systems, and organisations failing to scope AI access properly are 4.5x more likely to experience a security incident.
Questions worth separating out
Q: How should security teams govern AI agents that can access enterprise systems?
A: Security teams should govern AI agents as non-human identities with explicit ownership, scoped privileges, and continuous monitoring.
Q: Why do over-permissioned collaboration stores increase AI data leak risk?
A: Over-permissioned collaboration stores make it easy for AI systems to surface content that should never have been broadly reachable in the first place.
Q: What breaks when third-party AI use is invisible to the security team?
A: When third-party AI use is invisible, organisations lose control over where sensitive data is processed, retained, and exposed.
Practitioner guidance
- Map AI agents to governed identity records Inventory each AI system that can read, write, or reveal enterprise data, then assign ownership, purpose, privilege scope, and review cadence as you would for a high-risk service account.
- Test data exposure under hostile prompts Run red-team style evaluations against retrieval and summarisation workflows to see whether agents can surface unclassified, stale, or over-permissioned content when prompted adversarially.
- Unify token and delegated-access governance Bring OAuth applications, device-code flows, API tokens, and workload credentials into one access-risk view so that abuse patterns are visible across both human and machine entry points.

AI agents and cloud identity blind spots: what IAM teams must watch?

AI agents are becoming non-human identities before most organisations are ready to govern them. The article’s core insight is that copilots and autonomous systems are no longer passive software features. They make decisions, access data, and surface information in ways that require identity-style controls, not just application approval. That aligns directly with the governance gap highlighted in NHI work: systems with real access need lifecycle, privilege, and accountability boundaries. Practitioners should treat AI agents as governed identities with reviewable scope, not as convenience layers on top of existing IAM.
A question worth separating out:
Q: Who is accountable when an AI agent accesses sensitive data it was not meant to use?
A: Accountability sits with the team that approved the agent, its connectors, and its policy boundaries, not with the runtime behaviour alone. Organisations need ownership for intent, permissions, monitoring, and validation so they can prove whether the agent stayed inside its approved purpose. Without that, audit and regulatory response become retrospective guesswork.
