Pluto Security raises $42M as AI opens new enterprise security gaps

TechCrunch reports that Pluto Security, an enterprise security company, has raised $42M. The round lands against a widening sense of unease about what happens when AI tools spread across a whole organisation.

The article states the problem plainly: give everyone in a company access to AI tools, and people will use them in unexpected ways.

That unpredictability is steadily seeding fears that companies now have new, gaping security holes in their systems — or at least soon will.

For security teams the pressure is twofold. They have to keep up with AI tools employees adopt on their own, while assessing the fresh exposure those tools create around data flows and permission boundaries.

The funding also signals that investors increasingly treat AI-related security as a category in its own right. As models and agents reach deeper into everyday work, buying dedicated tooling and process for that risk is becoming a separate decision from legacy security frameworks.

What to watch next is whether these vendors can turn the broad anxiety about AI-driven vulnerabilities into measurable, deployable capability — and how quickly security budgets tilt in that direction as AI tools become the default inside enterprises.
