CST VerdictBased on our analysis of core features, integrations, here is our conclusion:
Network security teams with limited budgets who need visibility into encrypted traffic and lateral movement will get the most from Corelight Zeek; its passive monitoring generates 70+ log types from network packets alone, catching threats that endpoint tools miss. The 3,000+ event types tracked and 270+ community packages mean you're not building detection logic from scratch. Skip this if your team lacks the expertise to tune Zeek output or integrate raw network logs into your existing SIEM; Zeek demands engineering effort upfront and won't hand you pre-built dashboards.
Security teams with limited budgets who need packet-level visibility into encrypted traffic will find Stamus Clear NDR Community's Suricata foundation genuinely useful; it gives you what expensive NDR platforms charge six figures for, minus the managed service markup. The 400-plus visualizations and integration with Arkime for deep packet inspection mean you can hunt threats without sacrificing technical depth. Skip this if your team expects a turnkey platform with automated response or has no one comfortable tuning Suricata rules; this is deliberately lightweight and requires hands-on operators to get real value.
