Bias & Fairness (LLM-as-Judge)
This detection uses a secondary AI model to review the outputs of your primary AI system and flag content that looks biased or unfair. It is a monitoring aid, not a security control - it never blocks anything, it just reports what it finds.
How the attack works
An AI agent produces a response to a user or task. That response is passed to a separate AI scanner along with a rubric asking it to judge whether the content contains biased or unfair language. The scanner returns a verdict, which is logged for review. No action is taken automatically - the rule only ever reports, at most low severity.

Why it matters
Without this kind of check, an organization may not notice that its AI outputs are producing biased, discriminatory, or unfair content until a user complains or it becomes a public incident. This is a detection aid for that gap, not a fix - it does not stop the biased output from being generated or sent.
What you can do
- →Review flagged outputs manually before assuming they are genuine bias rather than legitimate discussion of a sensitive topic (e.g., security research, documentation, or test data mentioning protected characteristics).
- →Confirm your AI scanner/judge model is actually configured and reachable - this check fails open (allows silently) if no AI keys are set up, so a misconfiguration looks like a clean bill of health.
- →Track flagged-content trends over time rather than reacting to single flags, since the judge model's own bias or error rate will produce some false positives.
- →Pair this with human review processes for high-stakes or customer-facing AI outputs, since this control only reports and never blocks.
Known benign look-alikes
- Legitimate content discussing the flagged topic (security research, documentation, test data)
- AI scanner unavailable or no AI keys configured (fails open -> allow)
