CST VerdictBased on our analysis of core features, integrations, here is our conclusion:
Detection engineers and SOC analysts who need to standardize threat signatures across multiple SIEM platforms should start with Sigma; it's the only open format with 10,000+ community-written rules that port directly between tools without vendor lock-in. The format has adoption across Splunk, Elastic, Microsoft Sentinel, and a dozen other platforms, meaning your detection work compounds rather than evaporates when you swap vendors. Skip Sigma if your team lacks the expertise to write or maintain detection logic; it's a framework for people who already know how to hunt, not a turnkey rules engine that ships with pre-tuned detections.
