TL;DR: Managed agent boundaries differ sharply across Anthropic Claude Managed Agents, OpenAI ChatGPT Workspace Agents, and Google Gemini Enterprise, Mint's review says. Governance has to verify runtime isolation, delegated authority, and evidence trail before these systems move into production.
Editorial analysis by NHI Mgmt Group, based on content published by Mint: “Managed Agent Platforms: A Security Audit”.
Key questions
Q: Why do managed agents change NHI governance requirements?
A: Managed agents can use credentials, call tools, and act against business systems, so they behave like high-risk non-human identities.
Q: What breaks when a managed agent has broad runtime or egress access?
A: The agent's blast radius expands from contained task execution to general-purpose action.
Q: What should security teams check before approving a computer-using agent for production use?
A: They should verify the agent’s authorisation scope, logging quality, escalation path, and review boundaries before it is allowed into a real workflow.
Practitioner guidance
- Define the agent boundary model first Classify each managed agent as runtime-isolated, workspace-delegated, or gateway-governed before allowing production use.
- Test delegated authority paths Document whether the agent uses end-user credentials, shared agent-owned credentials, or cryptographically bound agent identity, then verify who can trigger the action path and under what scope.
- Review sandbox and egress controls Confirm whether the agent runtime can reach the internet, approved hosts, MCP servers, or only a restricted sandbox, and require explicit sign-off for any outbound path that expands blast radius.
Bottom line: Managed agents are converging as a category, but the security boundaries behind them are not converging at the same pace.

Managed agents are becoming privileged automation surfaces, not just AI features. The comparison shows that enterprise buyers are evaluating systems that can act with business context, tools, and credentials, which places them in the same governance frame as other high-risk non-human identities. The practical conclusion is that agent security has to be reviewed as identity governance, not as model evaluation alone.
A question worth separating out:
Q: What is the difference between workspace delegation and governed agent identity?
A: Workspace delegation grants control through the collaboration layer, such as publishing, sharing, or app authentication, while governed agent identity ties the agent to a distinct, inspectable identity and policy path. The first manages who can invoke the agent. The second manages how the agent is recognised and constrained when it acts.
