Metasploitable3 vs SimSpace Cyber Range: 2026 Comparison
Metasploitable3 is a free cyber range training tool. SimSpace Cyber Range is a commercial cyber range training tool by SimSpace. Compare features, ratings, integrations, and community reviews side by side to find the best cyber range training fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Security teams building internal cyber ranges or red team labs should choose Metasploitable3 for its deliberately vulnerable attack surface and tight integration with Metasploit Framework, eliminating the setup friction of hunting for compatible targets. The 5,470 GitHub stars reflect sustained adoption by practitioners, and the free price point means you can spin up isolated instances for each training cohort without budget negotiation. Skip this if you need a modern Windows environment or current OS versions; Metasploitable3's older stack is the feature, not the bug, but it won't teach your team anything about patching contemporary vulnerabilities.
