In their own words

2 quotes, verbatim, with the date and a link to each.

There are real safety and security issues raised by AI, but they can be fixed. It's time to get to work instead of freaking out. That's why I'm joining Cognition as CISO.

Today, Corridor is joining Cognition, where we’ll be taking Devin Security to the next level. … We started Corridor almost two years ago with the mission of accelerating secure and autonomous software development. … AI agents can now execute end-to-end attack chains, and defenders need new tools to keep up.
