I Built an AI That Autonomously Penetration Tests a Target, Then Writes Its Own SIEM Defense Rules

Current Breach and Attack Simulation (BAS) tools just replay static scripts and generate PDFs. VANGUARD uses an LLM ReAct loop to autonomously hack targets, adapting to what it finds and streaming its reasoning live via SSE. After the assessment, it automatically synthesizes and deploys Elasticsearch KQL rules to catch the exact vulnerabilities it just exploited.
