Browse the built-in catalog (239 techniques across 14 domains). Each technique opens with a full breakdown — overview, how it works, lab-safe simulation, raw logs — plus, where available, a validated detection rule from SigmaHQ and its KQL converted by the official pySigma backend (218/239 techniques carry a real Sigma rule; 174 include ready KQL). The rest fall back to clearly-labelled templates. Everything is inline — no network, no chat step required.
