Agentic AI runtime trust: are your controls keeping up?

TL;DR: As agentic AI systems move beyond single prompts into agent-to-agent execution, autonomous tool use and chained reasoning create new trust, compliance and security risks that traditional AI controls were not designed to handle, according to Tumeryk. Runtime policy enforcement and observability now matter more than after-the-fact review because agent decisions can propagate before teams ever see them.

Key questions

Q: How should security teams govern agentic AI when agents can delegate to sub-agents?

A: Treat delegation as a first-class identity boundary.

Q: Why do traditional AI controls fall short for agent-to-agent workflows?

A: Traditional AI controls usually focus on model output, content safety or later audit.

Q: What are the best practices for observability in agentic AI systems?

A: Capture the full decision trail, not just the final output.

Practitioner guidance

• Implement runtime trust evaluation Score every agent call at execution time and block or step up when the trust score indicates policy, data exposure or behaviour risk.
• Define explicit policy boundaries Express what agents may do, which tools they may invoke and which delegation paths are forbidden, then enforce those limits in the control layer.
• Record decision-level observability Capture the call, response, trust score and policy outcome together so security, compliance and incident teams can reconstruct agent behaviour.

Bottom line: Agentic AI changes the control boundary by turning trust into an execution-time decision instead of a retrospective review problem.
