  • Architect and automate runtime protections for LLM inputs and outputs, including injection mitigation, jailbreak defense, output verification, and sensitive-data egress checks.
  • Design security controls for autonomous agents, including scoped permissions, human-in-the-loop checkpoints, audit trails, and safe tool invocation.
  • Secure retrieval systems through access controls, source integrity, tenancy boundaries, and retrieval-boundary protections.
  • Assess the security, privacy, data-retention, and training-use posture of third-party models, inference providers, and vector stores.
  • Build telemetry and detections for AI abuse, anomalous tool invocation, prompt abuse, unusual retrieval, and model-mediated data exfiltration.
  • Ship reusable libraries, CI/CD checks, and evaluation harnesses that make secure AI patterns the default.
