TL;DR: Least privilege for AI agents depends on access graph visibility and policy enforcement across Microsoft Copilot Studio, Amazon Bedrock, Azure AI Foundry, ServiceNow, and Vertex AI, according to Veza’s August 2026 post, with its AI agent security coverage framed as a maturity roadmap. The governance problem is that agent behaviour changes the access model itself, so identity teams have to rethink entitlement, review, and control boundaries before autonomy widens the blast radius.

Questions worth separating out
Q: How should security teams govern AI agents that reason across multiple data platforms?
A: Security teams should govern the meaning layer, not just the access layer.
Q: Why do AI agents complicate privilege management for IAM teams?
A: AI agents can authenticate, call tools, and act with delegated authority, which means they behave like non-human identities with real execution power.
Q: What breaks when AI agents are reviewed like human users?
A: Human review assumes access is stable long enough to be observed, approved, and recertified.
Practitioner guidance
- Map AI agent access paths before enforcing privilege limits Build an access graph that includes tools, connectors, inherited permissions, and downstream resources.
- Separate provisioning review from runtime behaviour review Keep approval of initial entitlements distinct from monitoring what the agent actually does during execution.
- Standardise policy across every agent platform Align policy intent across Copilot Studio, Bedrock, Azure AI Foundry, ServiceNow, and Vertex AI so that one environment does not become the weak link in governance.
What's in the full article
Veza's full post covers the operational detail this post intentionally leaves for the source:
- Deep technical walkthroughs of AI Agent Security across Microsoft Copilot Studio, Amazon Bedrock Agents, Azure AI Foundry, ServiceNow AI Agents, and Vertex AI.
- The identity security maturity model that maps least privilege to stages of visibility, policy enforcement, and agent governance.
- Architecture-level examples of how access graphs and policy boundaries are applied in specific cloud and workflow environments.
- Product-specific implementation detail that implementation teams would need after the governance model is decided.

AI agent security is now a least-privilege architecture problem, not a feature checklist. Veza’s article shows that agent governance spans access graphs, tool reach, and platform-specific policy enforcement. That combination means practitioners cannot treat each agent surface as a separate point solution. The programme implication is to govern runtime access paths as a unified identity problem, not as disconnected product deployments.
A few things that frame the scale:
- 1 in 4 organisations are already investing in dedicated NHI security capabilities, with an additional 60% planning to do so within the next twelve months.
- 85% of organisations lack full visibility into third-party vendors connected via OAuth apps, which shows how quickly delegated access can outpace governance.
A question worth separating out:
Q: Should organisations rework NHI governance for AI agents separately from service accounts?
A: Yes, but not by creating a completely separate discipline. AI agents are still non-human identities, so the lifecycle, entitlement, and review model should stay consistent while the runtime controls change. The practical difference is that agents need behaviour-aware governance because their access path can shift during a session.
