Service · AI / LLM Security

Real red teaming for LLM apps, agents, and RAG pipelines.

LLM red teaming that goes past jailbreak prompts — we test prompt injection via indirect channels, tool-use abuse, data poisoning, model exfiltration, and multi-agent compromise.

What's covered

Prompt injection

Direct, indirect (web, doc, email), and cross-agent injection.

Tool / function-call abuse

Escalation via agent tools, arbitrary code execution, external side-effects.

Data leakage

Training-data extraction, RAG context leakage, PII regurgitation.

Model supply chain

Model provenance, fine-tune poisoning, dependency risk.

Multi-agent systems

Agent-to-agent trust abuse, orchestrator compromise, goal hijacking.

Deliverables

  • Attack library mapped to OWASP LLM Top 10 and MITRE ATLAS
  • Exploit PoCs with reproducible payloads
  • Guardrail recommendations (input / output / tool-use / human-in-the-loop)
  • Evaluator suite you can re-run in CI

Outcomes

  • A threat model for your AI stack that maps to real failure modes, not hype.
  • A CI-ready evaluator that catches regressions before customers do.

FAQ

We use a third-party model — is this relevant?
Yes. Most real risk lives in the app, the tool-use surface, and the data boundary — not the model weights.
Do you test agents?
Yes — agent frameworks are our most common engagement in 2026.
Talk to an operator

Your next finding is one scoping call away.

Thirty minutes with a real operator tells us what you need and what we can deliver. No BDR handoff, no sales engineer theater — the person you talk to is the person who scopes the work.
