Features, pricing, ratings, and pros & cons — compared head-to-head.
Datadog Cloud SIEM is a commercial security information and event management tool by Datadog. Splunk is a commercial security information and event management tool by Passus S.A.. Compare features, ratings, integrations, and community reviews side by side to find the best security information and event management fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Security teams already running Datadog for infrastructure and application observability should adopt Cloud SIEM to correlate security events with the underlying systems generating them; this eliminates the blind spot of traditional SIEMs that ingest logs in isolation. The platform covers continuous monitoring and incident response (NIST DE.CM and RS.MA), with multi-cloud log ingestion across AWS, Azure, and GCP built in rather than bolted on. Skip this if your priority is forensic depth or compliance reporting; Cloud SIEM is built for detection speed and operational context, not exhaustive audit trails.
Mid-market and enterprise SOCs needing to collapse detection and response into one platform should evaluate Splunk, particularly if you're running hybrid cloud infrastructure and need log correlation that actually catches behavioral anomalies instead of just indexing noise. Coverage across DE.CM and DE.AE means detection is genuinely strong, but RS.MA and RS.AN maturity lags, so you're getting a tool that surfaces incidents faster than it automates your way out of them. Skip this if your team is understaffed and betting on SOAR to do the heavy lifting; Splunk's automation is real, but incident response still requires people who know what they're doing.
