TL;DR: The OWASP Top 10 for Agentic Applications 2026 frames AI agent risk around hijacking, tool misuse, identity abuse, supply chain compromise, and cascading failures, with three of the top four risks tied to identities and delegated trust, according to Astrix Security. That makes agent governance an identity problem first, because access review models assume stable actors, not systems that combine credentials and act at runtime.
Editorial analysis by NHI Mgmt Group, based on content published by Astrix Security: “The OWASP Agentic Top 10 Just Dropped – Here’s What You Need to Know”.
Key questions
Q: How should security teams govern AI agents that can choose tools at runtime?
A: Security teams should govern runtime agent choice as an access event, not as a simple application action.
Q: Why do autonomous AI systems create more identity risk than normal automation?
A: Normal automation follows a fixed path, but autonomous systems can interpret goals, choose actions, and continue without waiting for a person.
Q: What are the signs that administrative access to an agent platform is too broad?
A: The clearest warning sign is when everyone can build, execute, and administer everything.
Practitioner guidance
- Inventory agent credentials and delegated sessions Map every key, OAuth token, service account, and session an agent can use, then identify which permissions are inherited rather than explicitly assigned to the agent role.
- Restrict agent tool access by task context Limit which tools an agent can call, under what conditions, and with what business purpose, especially for actions that can delete, move, or disclose data.
- Verify third-party tool provenance before connection Treat every external tool definition, MCP server, and agent dependency as a trust decision that needs ownership, provenance, and scope checks before exposure to sensitive systems.
Bottom line: The article frames the OWASP agentic top 10 as an identity and privilege problem, not just an AI safety taxonomy.

Identity is no longer just the perimeter for agentic systems, it is the execution substrate. Once an agent can combine credentials, choose tools, and act inside live workflows, the old separation between authentication and authorisation stops describing reality. The security question becomes how much delegated authority the agent can carry at runtime, and that is an IAM and NHI governance issue before it is an AI issue. Practitioners should treat agent identity as the control plane for agentic access.
A question worth separating out:
Q: What should organisations do when an AI agent crosses from QA into production?
A: They should force a new trust decision at the boundary and not reuse the original QA authorisation. Production access should depend on a fresh assessment of purpose, context, and issuer trust. Without that boundary, the agent inherits more privilege than the environment was meant to allow.
