TL;DR: Obsidian Security’s AI agent monitoring adds behavioural visibility to SaaS environments, but its own framing shows that observability after authentication cannot replace the identity controls agents need in production, according to WorkOS. The real issue is the gap between access granting and access governance, where AI agents inherit SaaS permissions before security teams can meaningfully constrain or verify them.
Editorial analysis by NHI Mgmt Group, based on content published by WorkOS: “Obsidian Security for AI Agent Security: Features, Pricing, and Alternatives”.
Key questions
Q: What breaks when AI agent monitoring is treated as an authentication control?
A: Access governance breaks because the organisation learns what the agent did, but not whether the agent should have been able to enter in the first place.
Q: Why do AI agents increase risk in SaaS environments?
A: AI agents increase risk because they can operate through existing application permissions and continue using them as tasks change.
Q: How should security teams measure whether AI is helping rather than hiding risk?
A: Security teams should measure AI using outcome metrics that include access scope, session length, revocation speed, and auditability.
Practitioner guidance
- Define the agent authentication boundary Separate the systems that mint access from the systems that observe usage, and assign ownership for both.
- Constrain delegated SaaS permissions Review OAuth grants, app scopes, and integration tokens for every AI agent and remove any access that exceeds the minimum task requirement.
- Add lifecycle controls for machine identities Put AI agents into the same joiner-mover-leaver discipline used for other non-human identities so access is revoked when the workload, workflow, or owner changes.
Bottom line: AI agent monitoring improves SaaS visibility, but it does not replace authentication or authorisation controls that define what the agent can reach.

Authentication and observability are different control planes, and conflating them weakens both. Behavioural monitoring can improve visibility, but it does not issue trust, narrow scope, or govern access lifecycles. For AI agents, the control that matters first is whether the identity boundary was safe enough to permit access at all. Practitioners should treat runtime visibility as supplementary rather than foundational.
A few things that frame the scale:
- Gartner predicts that more than 50% of successful cyberattacks against AI agents through 2029 will exploit access control weaknesses.
A question worth separating out:
Q: What is the difference between agent observability and agent authorisation?
A: Agent observability shows what an identity did after access began, while authorisation decides whether that identity should have had access and how much. In production, authorisation is the preventive control and observability is the detective one. They solve related problems, but they are not interchangeable.
