Compare features, ratings, integrations, and community reviews side by side to find the best security information and event management 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 already running Zeek for network telemetry and Elasticsearch for log aggregation should use zeek2es.py to close the integration gap without custom Python work. The tool handles Zeek's native JSON output directly into Elasticsearch bulk format, cutting weeks off a DIY pipeline and eliminating parsing errors that leak events. Skip this if your team lacks Elasticsearch infrastructure or hasn't yet committed to Zeek; the narrow integration scope means it solves one problem exceptionally well and nothing else.
Gravwell Security Data Platform
Security teams in mid-market and enterprise environments that need to hunt threats across raw, unnormalized data will get the most from Gravwell Security Data Platform; its structure-on-read architecture and unlimited ingest capacity let you ask questions you didn't know to ask during onboarding, which matters when you're chasing adversaries through hybrid infrastructure. The indexer-based pricing model removes the typical volume penalty, and coverage of Detect and Analyze functions (DE.CM, DE.AE, RS.AN) reflects genuine strength in threat investigation rather than just log storage. Skip this if you need a fully managed cloud SIEM with pre-built compliance dashboards or if your team lacks SQL-adjacent query skills; Gravwell rewards operators who think like hunters, not security analysts who want point-and-click threat detection.
