A Decade of Proactive Security Operations
The Auto Club Group (ACG) is the second largest and fastest-growing American Automobile Association (AAA) club in North America, trusted by over 13 million members and supported by 10,000+ employees. Guided by their mantra of “always doing what’s right,” ACG places the highest priority on protecting its customers, their data, and its own 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interconnected SIEMs, cloud environments, and applications—complicated threat identification and mitigation, while outdated tools created operational bottlenecks and fragmented visibility.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.

Resilient Security Operations a Decade in the Making
ReliaQuest’s decade-long partnership with ACG has transformed their security program into one that is scalable, proactive, and highly effective.
Powered by GreyMatter’s modular architecture, ACG gained the agility to anticipate and respond to evolving threats while maintaining continuous protection. Together, ACG and ReliaQuest are building a security model that’s prepared for the future.
“In the last decade, we’ve changed our detection and response technology stack three times to stay ahead of threats,” said Gopal Padinjaruveetil, CISO at ACG. “GreyMatter has been instrumental in guiding us through this evolution, and our members and leadership can sleep well at night knowing our security program is proactively protecting them.”
With ReliaQuest, ACG continues to lead the way in protecting its members, ensuring the freedom of mobility remains secure for generations.
Cybersecurity is a game of speed. The attacker’s velocity is increasing, and we needed to match that pace. GreyMatter helped us accelerate detection, investigation, and response times, and together we’ve increased our threat coverage by over 200%Gopal Padinjaruveetil Chief Information Security Officer, Auto Club Group
