CST Verdict

Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:

PEzor

Red teamers and penetration testers running adversary simulations need PEzor to pack shellcode and PE files without triggering static signatures that commodity AV will catch immediately. The tool's 2,077 GitHub stars reflect adoption by practitioners who've validated it in real engagements, and its open-source status means you can audit or modify the packing routines if your targets run custom detection. Skip this if you're looking for post-exploitation frameworks with C2 built in; PEzor does one thing,obfuscation,and doesn't bundle command infrastructure.
