Passive Network Audit Framework (PNAF) v0.1.2 vs TEHTRIS NTA: Side-by-Side Comparison (2026)

Passive Network Audit Framework (PNAF) v0.1.2

Security teams running threat hunts or building detection baselines on a budget will find value in Passive Network Audit Framework v0.1.2's ability to extract network behavior patterns without active probing, reducing alert fatigue from intrusive scanning. It's a Honeynet Project tool with 32 GitHub stars, meaning it's maintained by threat researchers but hasn't reached wide adoption; you're getting upstream detection work, not a polished product. Skip this if you need real-time alerting or vendor support; PNAF is for engineers comfortable reading code and tuning detection rules themselves.

TEHTRIS NTA

Mid-market and enterprise security teams with hybrid IT/OT networks need TEHTRIS NTA for its Layer 3-7 protocol visibility across industrial environments where most NDR tools fall short. The 80,000+ detection rules and automatic integration into the TEHTRIS XDR AI PLATFORM mean alerts reach your analysts with context already attached, not as raw noise requiring manual enrichment. Skip this if you're looking for a standalone tool; TEHTRIS NTA assumes you're investing in their platform ecosystem, and its strength in detection and forensics (DE.CM, DE.AE, RS.AN coverage) comes at the cost of limited incident response automation compared to pure SOAR-integrated competitors.
