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

Exabeam NetMon

Mid-market and enterprise security ops teams that struggle to spot lateral movement and data exfiltration in encrypted traffic should prioritize Exabeam NetMon. Its network traffic analysis catches what endpoint tools miss, and the dual NIST coverage in Continuous Monitoring and Adverse Event Analysis shows real depth in both detection and investigation. Skip this if your network is mostly cloud-native with minimal east-west traffic; NetMon assumes a hybrid environment where network packets still tell the story.

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.
