Features, pricing, ratings, and pros & cons — compared head-to-head.
C3 is a free offensive security tool. Havoc Framework is a free offensive security tool. Compare features, ratings, integrations, and community reviews side by side to find the best offensive security fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Red teamers and penetration testers who need to quickly prototype custom C2 channels without writing infrastructure from scratch should use C3; its integration with existing offensive toolkits like Metasploit and Cobalt Strike cuts weeks off typical channel development. The framework ships with working examples for HTTP, DNS, and HTTPS protocols, letting operators focus on evasion logic rather than socket programming. Skip this if your team needs a polished UI or commercial support; C3 is deliberately a builder's tool for operators comfortable with code.
Red teams and penetration testers building custom C2 infrastructure will find Havoc's malleable profiles and team collaboration features faster to operationalize than Cobalt Strike, especially at zero cost. The 8,200-plus GitHub stars reflect active community contribution to payload obfuscation and evasion techniques that actually work against modern defenses. Skip this if your priority is managed C2 services or Windows-only operations; Havoc's strength is flexibility for operators who want to own their implant behavior, not outsource it.
