What is NuGuard?

NuGuard builds an AI Software Bill of Materials (AI-SBOM) for your agentic application, then checks it in stages: static analysis of the AI stack, policy checks, behaviour tests and red-teaming against a live target, including prompt-injection attacks. It installs with pip, and a hosted platform is also available.

Third-party open-source projects. We are not affiliated with their authors; repositories are provided as-is by their maintainers. Review each project's license, code and security before installing. See our Disclaimer.

Pros: what NuGuard does well

Tests real prompt-injection attacks against your agent
Open-source CLI with a hosted option

Cons: where it falls short

Needs security know-how to act on the findings

Who NuGuard is for

Who can skip it

People not building AI applications.
