Passive Network Audit Framework (PNAF) v0.1.2 vs Solana Networks SmartFlow: 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.

Solana Networks SmartFlow

Mid-market and enterprise security teams with mature network infrastructure will get the most from Solana Networks SmartFlow because its anomaly detection actually catches encrypted malware and zero-day activity that signature-based tools miss. The tool analyzes 20+ statistical measures per flow and maps geographic access patterns, giving you the network visibility most teams lack when EDR and firewalls leave gaps. SmartFlow prioritizes detection over response; you get forensic drill-down and trend analysis but no automated remediation, so it works best for organizations with the ops maturity to act on alerts without hand-holding. Skip this if you need an all-in-one platform that handles both detection and containment.
