CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Startups and mid-market SOCs building detection programs from scratch should use Sigma Query to avoid reinventing rules; 3,000+ community-maintained detections mapped to 385+ MITRE ATT&CK techniques means you start with mature baselines instead of blank templates. The free model and cloud deployment eliminate procurement friction, and multi-platform coverage across Windows, Linux, cloud providers, and network appliances lets you apply the same rule set across your entire stack without rewriting. Skip this if your team lacks SIEM experience or needs rules packaged inside a commercial product with vendor support; Sigma Query requires you to understand your detection logic well enough to integrate and tune community rules yourself.
Security operations teams building Windows detection infrastructure on tight budgets should adopt sysmon-modular for its pre-built, community-maintained Sysmon rulesets that eliminate weeks of tuning work. With nearly 3,000 GitHub stars and active maintainers shipping modular configs for process creation, network activity, and registry changes, you're inheriting battle-tested detection logic rather than starting from scratch. This is free software that trades vendor support for a self-service model, so skip it if your team needs commercial SLA backing or can't maintain a homegrown Sysmon pipeline.
