Corelight Open NDR Platform vs RDFP: Side-by-Side Comparison (2026)
Features, pricing, ratings, and pros & cons — compared head-to-head.
Corelight Open NDR Platform is a commercial network detection and response tool by Corelight. RDFP 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.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
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.
Security teams running Zeek for network visibility will find immediate value in RDFP for identifying unauthorized or outdated Remote Desktop clients on the wire, something most NDR platforms treat as noise rather than a detection signal. The script requires no additional infrastructure beyond existing Zeek deployments and costs nothing, making it a quick add to detect client-side RDP vulnerabilities that endpoint tools often miss. Skip this if your organization relies on application allowlisting or has already eliminated RDP from your environment; RDFP is tactical network hygiene, not a replacement for access controls.
