Corelight Open NDR Platform vs cPacket Security Solutions: Side-by-Side Comparison (2026)

Corelight Open NDR Platform

Security teams running hybrid infrastructure who need to see east-west traffic patterns that perimeter tools miss will get the most from Corelight Open NDR Platform. Its foundation on Zeek and Suricata gives you transparent packet analysis at scale, and the platform scores strongly on NIST DE.CM and DE.AE, meaning detection and forensic depth are real strengths. Skip this if your org lacks network engineering resources to tune and maintain sensor placement; Corelight demands more operational overhead than managed detection services, and weak alert tuning will bury your team in noise.

cPacket Security Solutions

Mid-market and enterprise security teams dealing with encrypted traffic and multi-cloud packet visibility should start here; cPacket Security Solutions delivers lossless 200Gbps capture with zero packet drop (third-party verified) and agentless deployment, which means you get forensic completeness without touching your infrastructure. The platform excels at the front end of your detection pipeline, covering DE.CM and DE.AE in NIST CSF 2.0, but it's a packet broker and observability layer, not an incident response platform, so you'll still need NDR or SIEM to act on what it finds. Skip this if your team lacks the infrastructure expertise to integrate packet intelligence into existing security tools or if you're looking for a turnkey detection solution without integration work.
