Published by CapitalGuard Security Research · Updated July 12, 2026

Protect high-impact paths

Keep credentials, production configuration, auth, billing, infrastructure, migrations, workflows, and customer data outside ordinary agent access.

Approve consequential actions

Require a human decision before commands that install software, contact external systems, deploy code, change permissions, mutate data, or upload files.

Measure before and after

Use the CapitalGuard Risk Score and policy history to verify whether new permissions or workflows reduce or increase AI-agent exposure.

Next step

Buy the license that fits the current scope.
