FireCompass AI-powered Pen Testing vs nfspy: Side-by-Side Comparison (2026)

nfspy

Red teamers and penetration testers who need to simulate NFS credential theft will find nfspy invaluable for exposing how easily clients can be spoofed on misconfigured networks; it's the only free tool that does this specific attack without requiring kernel modules or custom compilation. The 299 GitHub stars and zero dependencies make it trivial to deploy in lab environments or during engagements where you need to validate NFS ACL weaknesses quickly. Skip this if your focus is post-exploitation persistence or lateral movement beyond the NFS protocol itself; nfspy is a narrow, sharp instrument for one attack surface, not a general-purpose network compromise tool.
