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

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.
