Original: Building a 10-Agent Security Civilization with Qwen and Alibaba Cloud 🛡️🤖

Short summary

NEXUS is a 10-agent autonomous security system from the Qwen Cloud hackathon that replaces error-prone SAST tools with specialized agents handling discovery, exploitation, verification, governance, and patching. A Governance Council of three independent personas debates vulnerability severity using distinct criteria (technical vectors, business impact, exploitability). The architecture uses DashScope API, pgvector semantic memory, and Redis/PostgreSQL for real-time orchestration.

  • 10-agent system eliminates SAST false positives by requiring PoC generation and multi-agent consensus validation
  • Governance Council averages three independent severity scores (CVSS technical, business impact, exploitability-in-wild)
  • 3-tier memory (Redis L1, PostgreSQL L2, pgvector L3) enables learning across scans via semantic similarity search
