Why self-hosted matters for AI security testing

One thing is becoming very clear while building PromptBrake: For AI security testing, the deployment model is part of the trust layer.

A lot of teams want to test:

• sensitive prompts

• customer chatbot flows

• production AI behavior

without that data leaving their own infrastructure.

That’s a big reason we recently added self-hosted enterprise deployments to PromptBrake.

We’re increasingly thinking about AI security testing as: “Test the AI endpoint your company actually ships — inside your own infrastructure.”

Curious if others building in AI/security are seeing the same shift toward private/local execution becoming a core trust requirement.
