CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Infrastructure and security teams already running Datadog for observability should adopt its SIEM capabilities to avoid another tool license; the platform's strength is correlating security signals across logs, metrics, and traces from applications you're already monitoring, which catches lateral movement faster than point solutions. Datadog's free tier lets you ingest and retain 15 days of logs at no cost, making it genuinely accessible to smaller teams. Skip this if you need best-of-breed threat hunting or forensics,Datadog's security features are built for real-time detection and response, not deep historical investigation.
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.
