CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Teams managing multiple SIEMs or migrating detection logic between platforms will find Alterix valuable for the mechanical task of converting Sigma and Yara rules without rewriting them from scratch. The free price point and GitHub availability mean zero friction for testing whether the conversion quality meets your standards before committing engineering time. Skip this if your organization has settled on a single SIEM with native rule support or if you need human-validated detections; Alterix handles syntax translation, not threat intelligence or rule tuning.
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.
