Your system prompt is your first and cheapest line of defense, and most are trivially extractable or steerable. I rewrite yours so it holds.

What's included:

Review of your current system prompt, guardrails and model configuration

A hardened rewrite: injection-resistant structure, role separation, tool-use constraints, refusal behavior

Adversarial testing of the new prompt against extraction and steering attacks

Before/after test results so you can see what changed

A short guide for your team on maintaining it as the product evolves

Timeline: 4 working days.
