About HOL Guard #
HOL Guard is an Apache-2.0-licensed runtime-control tool for supported agent integrations. It evaluates covered actions against configured policy and records decisions; coverage depends on the harness and event surface. A public repository, release and Python package were available during review. Local functionality is separate from optional paid cloud features. No interception, scan or protection guarantee was tested.
HOL Guard is an open-source project written primarily in Python, with 766 stars on GitHub. It was last updated in October 2026.
