TL;DR: AI-powered vulnerability triage only becomes safe to use when it is benchmark-validated before deployment, because LLM non-determinism, model drift, and 71% to 88% false-positive rates can turn security automation into an accountability problem, according to Pixee. The governance challenge is no longer whether AI can triage findings, but whether the system making security decisions is auditable, reproducible, and accountable under change.

Questions worth separating out
Q: What breaks when AI is used for vulnerability triage without validation?
A: Without validation, AI triage can change its answers across runs or model updates, which breaks consistency, auditability, and trust.
Q: Why do non-deterministic models create governance problems in AppSec?
A: Because security decisions need to be reproducible.
Q: How do organisations know if AI triage is actually working?
A: Measure whether the AI improves high-fidelity detection, shortens time to verified response, and preserves reviewer trust in its decisions.
Practitioner guidance
- Define a benchmark gate before AI triage goes live Require every model used for vulnerability triage to pass a curated benchmark of real findings with verified ground truth before production deployment.
- Revalidate after every model or prompt change Treat foundation model updates, prompt revisions, and analyzer tuning as control changes.
- Track human overrides as a governance signal Capture every reviewer override, group them by vulnerability class, and use the patterns to identify drift, ambiguous scanner output, or model blind spots.

Benchmark-validated AI is becoming a governance requirement, not a feature request. Once a model influences vulnerability disposition, it is part of the security control surface. The important question is no longer whether the model can help, but whether its outputs are repeatable, auditable, and version-controlled enough to support risk decisions. Security leaders should treat triage validation as a control objective, not a product capability.
A question worth separating out:
Q: Who is accountable when an AI triage system misses an incident?
A: The organisation remains accountable, even if software performed the first-pass analysis. Risk owners, SOC leadership, and the control owner for the workflow need to define approval rights, review obligations, and evidence retention before the system is relied upon.
