Splunk vs Datadog Security

Datadog Security excels when security and observability need to live in one platform, offering unmatched context for cloud-native threat detection. Splunk is the more mature SIEM with deeper security analytics, but lacks Datadog's native integration between infrastructure monitoring and security operations.
