TL;DR: Traditional DLP and DSPM controls miss AI-native threats because they cannot reason about intent, semantics, or policy context, according to Lasso Security. LLM-as-a-judge inserts a model-based enforcement layer that can inspect prompts, tool calls, and outputs in real time, but production use still faces latency, scale, cost, and adversarial-jamming constraints.

By the numbers:
- 96% of technology professionals identify AI agents as a growing security threat, and 66% believe this risk is immediate.
- 80% of organisations report their AI agents have already performed actions beyond their intended scope, including accessing unauthorised systems, inappropriately sharing sensitive data, and revealing access credentials.
Questions worth separating out
Q: How should security teams govern AI systems that make policy decisions at runtime?
A: Security teams should place a policy decision point in the AI request path, then define clear allow, block, redact, and review outcomes.
Q: Why do DLP and DSPM controls miss many AI-native risks?
A: DLP and DSPM are built to find known data forms, locations, and patterns, but AI abuse often appears as ordinary language with harmful intent hidden inside it.
Q: What breaks when LLM policy enforcement is bolted on after the model response?
A: Late-stage enforcement lets unsafe prompts influence the model before any control intervenes, which means the risky reasoning, tool use, or data retrieval has already happened.
Practitioner guidance
- Instrument the AI request path for inline adjudication Intercept prompts, tool calls, and outputs before they reach the primary model, and route them through a policy decision point that can allow, block, redact, or escalate based on context.
- Separate semantic review from pattern-based detection Keep regex, entropy, and classifier checks for obvious secrets, but add a context-aware layer for prompts that contain hidden exfiltration intent or policy evasion.
- Version AI policies like other governance artifacts Track policy prompts, approval logic, and enforcement changes so security and compliance teams can review what the judge enforced at any point in time.

Lasso Security's full blog post covers the operational detail this post intentionally leaves for the source:
- A step-by-step LLM-as-a-judge pipeline from ingress capture to verdict enforcement, including where proxy, middleware, and sidecar patterns fit.
- Implementation examples for policy prompts, risk scoring, and response actions such as block, redact, or review.
- Performance discussion on latency, throughput, and cost tradeoffs when the judge runs inline at enterprise scale.
- The article's own discussion of prompt-injection attacks, JudgeDeceiver-style manipulation, and policy drift handling.

LLM-as-a-judge is a governance layer, not just a security feature. The control shifts AI protection from pattern matching to contextual adjudication, which is why it can catch prompt injection, semantic exfiltration, and policy drift that DLP cannot see. That makes it relevant to both NHI governance and broader AI identity oversight. Practitioners should treat it as runtime policy enforcement for AI behaviour, not as a content scanner.
A few things that frame the scale:
- 96% of technology professionals identify AI agents as a growing security threat, and 66% believe this risk is immediate, according to AI Agents: The New Attack Surface report.
- Only 52% of companies can track and audit the data their AI agents access, leaving 48% with a complete blind spot for compliance and breach investigation.
A question worth separating out:
Q: Who is accountable for AI policy violations when the judge model is wrong?
A: Accountability sits with the organisation operating the AI system, not with the model itself. Teams need clear ownership for policy definitions, model tuning, escalation handling, and evidence retention. If the judge fails open or misclassifies a request, the governance failure is operational, not abstract.
