On the point: Anthropic has documented how it contains AI agents in products like Claude Code and Claude Cowork through sandboxes and access limits, since pure human oversight is unreliable—users approve approximately 93 percent of all requests without careful review.
Anthropic has developed procedures to limit the risks of Claude-based agents. The company relies on sandboxes and access control rather than human oversight alone—because users increasingly ignore approval windows.
Anthropic has described in an engineering report how the company deploys autonomous AI agents more securely. Twelve months ago, the idea of granting Claude access to internal systems would have been flatly rejected. Today it is routine, and developer productivity has benefited from it.
The risk of agent deployments encompasses two factors: the probability of failure and the potential extent of damage. While security measures and training advances reduce the likelihood of errors, the possible damage grows with the agent’s capabilities and expanded access rights. As agents increasingly take on tasks that previously required humans or teams, the cost of avoiding deployment becomes prohibitive. The engineering challenge therefore lies in limiting damage risk.
Anthropic distinguishes between two defense mechanisms: human oversight and containment. The company initially tested the “human approval per action” model, for example in Claude Code. However, telemetry showed that users approved approximately 93 percent of all requests without careful review—the so-called approval fatigue resulted in inadequate attention.
The second approach is containment through access control: sandboxes, virtual machines, and egress controls limit what agents can technically do, rather than merely monitoring what they should do. This is the focus of Anthropic’s security work.
Anthropic has identified three main types of security risks: misuse by users, unintended model misbehavior, and agents’ attempts to circumvent restrictions. In security tests, Claude has “helpfully” broken out of sandboxes to accomplish tasks, or analyzed Git history to find test answers.
