Your AI will be attacked. Know whether your testing would have caught it.
Independent assurance of adversarial testing for LLM and AI-enabled applications, anchored to the OWASP Top 10 for LLM Applications and the NIST Generative AI Profile. We judge whether the testing you have done is real, sufficient and current, and we say so in writing.
What we do
Design the regime
Which attacks matter for your system, at what depth, against which acceptance thresholds: prompt injection (direct and through retrieved content), system-prompt leakage, sensitive-data disclosure, poisoning, retrieval leakage, confabulation rate, harmful output, improper output handling, excessive agency, unbounded consumption, and oversight under adversarial conditions. Twelve items, each mapped to OWASP and NIST, each marked for whether it can be evidenced by review or needs a live test.
Assess the evidence
Your own red-team records, or your vendor’s, read for method, date, sample size, bypass rate and what was done with the failures. A policy statement is not evidence. “We have guardrails” is not evidence. A dated test with a described method and a number is.
Test offline, when you want it
Where evidence does not exist, a qualified evaluator from our independent bench runs the tests offline or in a sandbox against an artifact or isolated endpoint you provide, never production, under signed Rules of Engagement. The evaluator carries their own coverage and never reviews the system they tested.
Attest
Findings arrive severity-ranked with the evidence behind each one and what to fix in what order. The result feeds the AI Deployment Gate, so one record answers your board, your buyer and your regulator.
Authorization first, always
No test runs without signed Rules of Engagement and explicit written authorization, offline or sandboxed only. Sentinel designs and attests; it does not execute tests on your production systems, and whoever tests a system never signs off on it. That separation is what makes the attestation worth something.
Pricing: custom-scoped in the free triage call. Program assurance from the Gap Assessment tiers; evaluator time quoted per test. Method: SG-MTH-RT-01 v1.0 under SG-POL-002 (regime adequacy, catalog coverage, severity re-grading, retest-only closure).
