Attify Offensive IoT Exploitation is a commercial offensive security tool by Attify. Cobalt Strike's ExternalC2 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:
Mid-market and enterprise security teams building IoT device attack capabilities should choose Attify Offensive IoT Exploitation for its hands-on firmware and hardware exploitation training, which directly addresses the gap most offensive teams hit when moving beyond network pentesting into silicon-level attacks. The course covers the rare combination of JTAG debugging, ARM/MIPS binary reversing, and glitch attack techniques that your team will actually need to compromise modern IoT devices, and the vendor's five-person structure means instruction stays grounded in real exploitation work rather than theoretical frameworks. Skip this if your IoT testing stays at the application layer or if you need a generalist tool that covers multiple device types without deep specialization; Attify assumes you're already comfortable with low-level reverse engineering and want to compress months of self-teaching into structured methodology.
Cobalt Strike's ExternalC2 framework
Red team operators and penetration testers who need to test defenses against custom C2 channels will use ExternalC2 to bypass network detection by routing Cobalt Strike traffic through external redirectors and custom protocols. The framework is free and lets you replace Cobalt Strike's default HTTP/HTTPS beaconing entirely, which means your C2 can blend into legitimate traffic patterns your client's sensors won't flag. Skip this if your team runs assessments using only default Cobalt Strike profiles or lacks the network infrastructure to host and manage external redirectors; the setup friction and operational complexity only pay off when you're specifically validating detection gaps around custom C2 communications.
