Corelight Zeek is a free network detection and response tool by Zeek. Netis Cloud Probe is a free network detection and response tool. Compare features, ratings, integrations, and community reviews side by side to find the best network detection and response fit for your security stack.
Based 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.
Network operations teams building visibility into east-west traffic on constrained infrastructure will find Netis Cloud Probe valuable for its simplicity: packet capture and forwarding with zero licensing friction, backed by 960 GitHub stars and active open source maintenance. The tool excels at the Detect function in NIST CSF 2.0 by giving you raw packet-level observability across network segments without the overhead of commercial NDR appliances. Skip this if you need correlation, threat hunting, or automated response; Netis Cloud Probe is capture and transport, not analysis.
