When to choose Datadog Cloud SIEM
Datadog Cloud SIEM is suitable for organizations that operate primarily in cloud environments and prioritize a straightforward pricing model based on data ingestion. It caters to users who need extensive threat detection rules, real-time alert analysis, and automated incident workflows with 12-month data retention. Its integrations are focused on major cloud providers and collaboration tools. Organizations that are concerned about cost escalation with data usage and require broader deployment options beyond the cloud might find Datadog Cloud SIEM less suitable.
When to choose Splunk
Splunk is suitable for organizations seeking flexible pricing models (workload-based, ingest, entity-based, activity-based) and diverse deployment options, including cloud, private cloud, or on-premises. While it does not list a specific starting price or free tier, its strength lies in offering a predictable cost structure and multiple tiers to accommodate varying organizational needs. Organizations that require immediate pricing transparency without consultation and a clear starting price might find Splunk's pricing approach less direct.
