Platform / Guardrail Assurance
Guardrail Assurance
A guardrail you have not adversarially tested is a guardrail you cannot trust. Penaxtra runs a dedicated probe suite against your guardrail-fronted endpoints to prove they hold under attack.

Problem
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 approaches it
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.
