TL;DR: Autonomous AI agents are creating a security frontier that traditional tools cannot adequately protect, according to Obsidian Security, because they can make decisions, access APIs, and move data across cloud and SaaS systems at machine speed. Access review processes assume privilege persists long enough to be observed; autonomous agents can acquire and discard access inside a session, collapsing that governance model.
NHIMG editorial — based on content published by Obsidian Security: AI Security Posture Management: Continuous Protection for AI Agents
By the numbers:
- 96% of technology professionals identify AI agents as a growing security threat, and 66% believe this risk is immediate.
- When AWS credentials are exposed publicly, attackers attempt access within an average of 17 minutes, and as quickly as 9 minutes in some cases.
Questions worth separating out
Q: What breaks when AI agents are not governed at runtime?
A: Without runtime governance, an agent can shift behaviour after provisioning and still execute actions that were never reviewed in context.
Q: Why do autonomous AI agents complicate least privilege models?
A: Least privilege is usually assigned before execution and reviewed after the fact, but autonomous agents can decide, act, and complete work within one session.
Q: How do you know if AI agent monitoring is actually working?
A: It is working when you can explain why a sequence of actions was allowed, blocked, or escalated, using evidence from the full chain rather than a single request.
Practitioner guidance
- Implement continuous discovery for AI agent identities Map every active agent, its credentials, tool connections, and data paths across cloud and SaaS environments.
- Bind permissions to task scope Replace broad standing access with scope-limited access tied to the specific workflow, dataset, or API action the agent needs at runtime.
- Monitor behavioural drift as an identity signal Establish normal patterns for each agent’s API use, data access, and tool sequence, then alert when behaviour crosses the approved boundary.

AI security posture management is the governance layer agentic AI now needs. Traditional IAM assumes access can be catalogued, reviewed, and refined around stable users or static services. Autonomous agents violate that assumption by changing behaviour inside the runtime window, so continuous posture management becomes the only workable control plane for agent identity, privilege, and action scope.
A few things that frame the scale:
- 98% of companies plan to deploy even more AI agents within the next 12 months, despite documented rogue behaviour in 80% of current deployments, according to AI Agents: The New Attack Surface.
- Only 52% of companies can track and audit the data their AI agents access, which means nearly half still cannot evidence what an agent touched during an incident or audit.
A question worth separating out:
Q: Who should own AI agent access decisions in an IAM programme?
A: Ownership should sit with the identity or security function, not the developer who needs the workflow to ship. Developers can describe operational need, but IAM, PAM, or NHI governance should set the policy boundary and enforce it centrally. That prevents local convenience from becoming permanent over-privilege.
