This Corelight white paper explains how combining Zeek and Suricata accelerates incident response. Suricata excels at signature-based detection while Zeek provides rich, protocol-linked logs for context. Corelight sensors unify these outputs, embedding Suricata alerts directly into Zeek logs with unique connection IDs, enabling faster pivots and reducing noise. Unlike open-source deployments that struggle with CPU bottlenecks, Corelight’s shared-CPU architecture scales elastically for high-throughput traffic. Integrated management via Fleet Manager lets teams stream curated alerts to SIEMs while archiving full Zeek logs, simplifying investigations and boosting detection efficiency.
