+Strix are autonomous AI agents that act like real hackers—they run your code dynamically, find vulnerabilities, and validate them with proof-of-concepts. Built for developers and security teams who need fast, accurate security testing without the overhead of manual pentesting or the false positives of static analysis tools.

 | Client-Side | XSS, prototype pollution, DOM vulnerabilities |
 | Business Logic | Race conditions, workflow manipulation |
 | Authentication | JWT vulnerabilities, session management |
+| Infrastructure | Misconfigurations, exposed services |
+
+## Multi-Agent Architecture
+
+Strix uses a graph of specialized agents for comprehensive security testing:
+
+- **Distributed Workflows** — Specialized agents for different attacks and assets
+- **Scalable Testing** — Parallel execution for fast comprehensive coverage
+- **Dynamic Coordination** — Agents collaborate and share discoveries
