Security Scenario Generator (SecGen)
Security teams building internal cyber ranges or running capture-the-flag training programs should use Security Scenario Generator because it eliminates the manual work of building vulnerable VMs from scratch; the open-source framework auto-generates realistic hacking scenarios that force defenders to actually practice exploitation and remediation instead of passively watching videos. With 2,749 GitHub stars and active community contribution, you're getting a tool that's actively maintained and battle-tested by university security programs and smaller penetration testing shops. Skip this if your org needs managed infrastructure, instructor dashboards, or compliance reporting tied to individual training completions; SecGen requires hands-on technical administration to operate effectively.
