CodeWall launches with $4M to run autonomous AI agents against enterprise defenses

London-based offensive security startup CodeWall launched with $4 million in pre-seed funding led by Osney Capital for autonomous AI agents that attack enterprises the way an outside hacker would. In an earlier engagement, an agent with no credentials gained read and write access to the production database behind McKinsey's Lilli AI platform within two hours. CodeWall pitches the ongoing testing as a replacement for the once- or twice-a-year penetration test.
