Across 21 of the biggest software companies on earth, including Apple, AWS, Microsoft, and Google, reported critical vulnerabilities never once cleared 100 per month for four straight years.
Then, this spring, they exploded past 600 per month. That is not a blip. It is AI industrializing the discovery of software flaws, and it forces a matching wave of defensive innovation that is now one of the most urgent, investable categories in tech. We pulled the funding rounds, the market numbers, and the exact whitespace so you can decide where to build, invest, or partner before this prices in.
In this issue you’ll find:
The 600/month signal: why the vulnerability surge means AI broke cyber for good
The symmetry trap: how AI made offense AND defense cheaper, and who wins that race
The three defensive plays with room to build (AI-native SOC, securing AI infra, agent security)
Where the money already moved: the AI-security rounds and market numbers that prove the thesis
The operator playbook: how to position before the category prices in
Hey, welcome to AI Market Fit!
Every week you’ll get two things, fast:
