Guardrail Assurance

Penaxtra runs a dedicated probe suite against your guardrail-fronted endpoints to check whether they hold under jailbreaks, injection, and data-leakage attempts.

The gap Guardrail Assurance closes

Teams deploy a prompt firewall, a content filter, or a third-party prompt gateway and assume it works. Vendors publish accuracy numbers on their own benchmarks. Nobody tests the guardrail in place, against the specific bypasses that matter, on the customer's own traffic shape.

How Penaxtra delivers Guardrail Assurance

Penaxtra ships a Guardrail Assurance probe suite that targets the guardrail itself: jailbreak pass-through, injection bypass, PII and secret leakage, and system-prompt exfiltration. Point a scan at a gateway-fronted endpoint and the suite reports which controls held and which let an adversarial request through, folded into the standard findings inventory with framework mappings.
