About Harden

Harden AIF is a innovative security layer designed specifically for AI coding agents, providing a local, free solution to enhance safety during development and deployment. It employs a post-trained model to scrutinize tool calls before execution, utilizing the current request and session context to ensure operations are secure and appropriate. What sets Harden apart is its focus on maintaining user privacy and control, as all checks are performed locally on your machine, eliminating reliance on external servers. This makes it particularly appealing to developers and organizations concerned about data security and compliance while working with AI-powered tools. Harden has demonstrated superior performance on key agent-security benchmarks compared to frontier models, highlighting its effectiveness in preventing potentially harmful or unintended actions by AI agents. Its user-friendly approach and focus on security make it a compelling option for teams seeking to integrate AI with robust safety measures without compromising privacy.
