CST VerdictBased on our analysis of available product data, here is our conclusion:
OCaml developers embedding malware detection into custom security tools should use ocaml-yara for direct access to YARA's pattern-matching engine without language boundary overhead. The bindings are maintained by Elastic and free, which matters for teams building detection pipelines that need to call YARA thousands of times per second without spawning subprocess overhead. This is a poor fit for teams expecting a polished UI or integration with third-party threat feeds; ocaml-yara is a low-level library, not a scanning platform.
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.
