Case Study: Fox Communities Credit Union cuts alert noise 93% and reduces MTTR by 70% with ReliaQuest GreyMatter

Fox Communities Credit Union Streamlines and Improves Security, Reducing MTTR by 70%

Fox Communities Credit Union (FCCU), a $2.7B member-owned financial institution serving over 127,000 members across 22 branches, needed to scale security operations and reduce overwhelming alert noise as its IT footprint expanded across on‑premises, endpoint, and cloud systems. FCCU partnered with ReliaQuest and adopted the ReliaQuest GreyMatter platform to gain adaptable, integrated visibility and enable the security team to focus on strategic work rather than triaging false positives.

ReliaQuest implemented GreyMatter’s Open XDR platform, mobile app, and automated playbooks to streamline investigations and enrich alerts, which cut alert noise by 93%, improved visibility by 37% annually, increased MITRE ATT&CK detection coverage from 44% to 72%, and reduced mean time to resolve incidents by over 70%, with 93% of alerts closed by the platform—freeing FCCU to accelerate projects and improve risk reporting. ReliaQuest’s solution also provided the performance metrics and integrations needed for clearer executive communication and ongoing security program improvement.
