SENTINEL AI — Multi-Agent Security Assessment Platform

500 structured security scenarios across 20 AI-specific domains, run by a fleet of specialized security agents.

Delivered at: Spire Digi Solution
Role: Lead architect — platform design, specialized-agent model and the full 500-scenario security taxonomy.

The problem

Generic penetration testing wasn’t built for LLMs, RAG, agents, MCP and multi-agent systems. Assessing modern AI needs its own taxonomy, its own specialized attack agents, and an evidence-first, authorization-gated process end to end — not a checklist borrowed from conventional AppSec.
