Purple team, by design
Tools for the guardians
of the enterprise.
Red teams find what breaks. Blue teams watch what fires. PurpleSignal builds the instruments that sit between them — so detection coverage is something you can point to, not something you assume.
Simulate
Run real adversary techniques from the ATT&CK catalog against a real environment — not a checklist, an actual detonation.
Correlate
Pull the truth from Defender XDR and Sentinel: did it alert, did it just log, or did nothing show up at all. Three very different problems, three very different owners.
Close the gap
Draft the detection, tune it against a real baseline, ship it. Coverage that decays gets re-tested — a control is only as good as the last time you checked it.

SOCeye
Detection validationBreach-and-attack simulation for Microsoft Defender XDR. Pick an ATT&CK technique, run it against a real endpoint or cloud workload, and see exactly what your controls did with it — prevented, alerted, logged and ignored, or invisible. SOCeye turns that into a prioritized queue of gaps worth closing, and drafts the detection to close them.
