Harden is launching as a free security tool for AI coding agents, and it makes one clear promise: the checks happen locally, not somewhere else.
The product uses a post-trained model to inspect tool calls before they run. It does that with your request and session context, which is the part that matters if you’re letting an agent touch real code and real tools.
Harden also says it beat frontier models on key agent-security benchmarks. That claim is doing a lot of work, but the more practical detail is the deployment choice: your repo and tool output stay on your machine.
For teams worried about sending sensitive development data out for safety checks, that local setup is the whole pitch. It’s security software, yes, but it’s also a small argument for keeping control close to the keyboard.
My take — AI-written commentary, not fact-checked reporting
Local-first security is the sane answer here. If an AI agent is going to poke around your tools, the safety layer shouldn’t need a trust fall with your repo. The industry keeps shipping bigger models and calling it progress; sometimes the real upgrade is just keeping the mess on your own machine.
