Case Study: University of Kansas Health System achieves 98% increase in visibility and faster incident response with ReliaQuest GreyMatter

University of Kansas Health System Grows Visibility by 98% with GreyMatter

The University of Kansas Health System, a large Midwest healthcare provider serving about 2.5 million patients, faced siloed security teams (the Health System and the Medical Center), poor cross‑environment visibility, disparate toolsets, and an overworked incident response staff that relied on email for communications. To mature their security operations, the organization turned to ReliaQuest and its GreyMatter security operations platform.

ReliaQuest implemented GreyMatter (including automated response playbooks and a mobile app) plus pre‑built and custom detection rules to unify visibility and streamline triage; over six months visibility rose by 98% and detection coverage grew 110%. ReliaQuest filtered and resolved the vast majority of 75,000 alerts—escalating 174 for human review, of which 38 were true positives—yielding a ~99% reduction in alert noise, faster incident response, and higher analyst morale and productivity.
