Jot After Microsoft's own release of Project Perception, I'm seeing a lot of cybersecurity-focused harnesses popping as open source.
One of the oldest and most well known is Strix, which I initially thought was all about offence with vulnerability discovery and exploitation, but seems to also includes features for building the associated fixes.
Now OpenAI released the SDK and CLI for Codex Security. A few months ago it was Alibaba releasing Open Code Review. If you prefer the DIY way, Cloudflare also shared their own blueprint for what they call the Vulnerability Discovery Harness and Vulnerability Validation System.
I can see this approach growing if we can keep the token costs manageable, it will for sure cannibalize the bug bounty and maybe parts of penetration testing budgets.
