A Decade of Proactive Security Operations
ACG's partnership with ReliaQuest spans over a decade, during which time ACG seamlessly integrated security ecosystems from multiple acquisitions into the GreyMatter platform. This integration boosted their MITRE coverage by 83% and significantly enhanced visibility across 14 states, creating their first unified and proactive security posture.
Modernizing Security Operations to Scale with Growth
As ACG expanded and modernized its security operations, they faced regular significant challenges. Legacy on-premises systems struggled to adapt, exposing critical gaps in infrastructure, workflows, and visibility. The growing attack surface—spanning interconnected SIEMs, cloud environments, and applications—complicated threat identification and mitigation, while outdated tools created operational bottlenecks and fragmented visibility.
Meanwhile, ACG’s analysts were overwhelmed by the sheer volume of data and alerts, spending valuable time on manual processes instead of focusing on high-priority threats. Without a scalable solution to unify tools, modernize workflows, and reduce noise, ACG risked delays in responding to critical incidents.
ReliaQuest GreyMatter’s modular architecture addressed these challenges by delivering seamless integration, automation, and scalability to ACG’s security operations. GreyMatter empowered ACG to transition from reactive defense to proactive threat management without interrupting workflows or visibility.
