CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Red teamers and security researchers who need to validate steganography detection controls should use Image Steganography Tool for its straightforward LSB encoding implementation and zero operational overhead. The 1,066 GitHub stars and active C++ codebase mean you're working with battle-tested code that won't disappear mid-engagement. Skip this if you're looking for GUI-based tools or need support for advanced steganography methods beyond LSB; this is command-line and deliberately narrow in scope.
Mid-market and enterprise red teams will pick Fortra Cobalt Strike for the Malleable C2 language, which lets you reshape network indicators to match your target environment instead of fighting against detection signatures built for the tool's defaults. The shared team server and asynchronous low-and-slow communication model reflect NIST ID.RA and DE.AE coverage, meaning you can run realistic adversary simulations that actually test how your SOC detects slow exfiltration and lateral movement, not just fast attacks. Skip this if your organization needs purple team automation or wants the tool to generate its own reports without manual TTP documentation; Cobalt Strike is built for operators who know what they're hunting for.
