SaaS security vendors getting repriced upward on the back of AI demand is a clear signal that boards will fund defense for AI-era attack surfaces even as they squeeze other IT lines.

If you’re still hand-rolling backends for AI apps, at least benchmark these platforms before you commit to another bespoke stack.
