A security operations vendor that sponsors a college football bowl game raised $500 million to invest in agentic AI-driven cybersecurity automation and expand internationally.

ReliaQuest said the funding round values the Tampa, Fla.-based company at $3.4 billion and was led by EQT, KKR and FTV Capital. That’s more than triple the $1 billion valuation ReliaQuest received in December 2021 in conjunction with an investment from KKR. The company has more than $300 million in annual recurring revenue, is growing at more than 30% year-over-year and is operating profitably.
“Enterprise security teams have more data in more places than ever before, and the speed of the threat is rapidly increasing,” ReliaQuest founder and CEO Brian Murphy said in a statement. “CISOs need a way to contain threats within minutes without added cost or technical overhead, leveraging the latest innovations in agentic AI. This new investment is a key step along our growth trajectory as a company.”
ReliaQuest, founded in 2007, employs roughly 1,100 people and has raised more than $830 million in four rounds of outside funding. That includes $300 million in growth financing in August 2020 from KKR to accelerate development of the company’s cybersecurity intelligence platform. ReliaQuest, led since inception by Murphy, has sponsored a college football bowl game in Tampa since 2022 (see: ReliaQuest CEO Brian Murphy on Joining SecOps, Threat Intel).
The company’s GreyMatter platform is powered by agentic AI models that can operate and learn autonomously to automate security processes and significantly reduce the time to contain threats. Using GreyMatter’s automation and AI capabilities, ReliaQuest said its customers can now perform investigations 20 times faster and with 30% greater accuracy than traditional methods.
“By enriching GreyMatter with AI and automation capabilities, ReliaQuest has accelerated ahead of the pack, and now stands out as one of the only software vendors capable of managing security operations for the most complex enterprise environments,” EQT Partner Kirk Lepke said in a statement. ReliaQuest didn’t respond to Information Security Media Group interview requests.
What Makes ReliaQuest’s Approach to SecOps Different
ReliaQuest said its technology can contain threats within less than five minutes, helping security teams focus on higher-level business needs rather than mundane tasks. GreyMatter enables security teams to leverage their current or future technology stack to boost visibility and AI-driven automation, helping security teams detect, contain, investigate and respond to cyberthreats across many cyber solutions.
“When we first invested in ReliaQuest in 2020, we recognized its enormous potential given the rise of cyberattacks and the challenges cybersecurity teams faced in managing a multitude of tools with limited manpower,” KKR Partner Stephen Shanley said. “Over the years, the company has transformed with its leading AI-driven software platform, a relentless focus on innovation and a unique company culture.”
Since its last funding round, ReliaQuest bought Digital Shadows for $160 million in June 2022 to infuse its security operations platform with threat intelligence, attack surface management and dark web monitoring. The acquisition was intended to provide customers with more visibility and context around potential threats facing their networks, endpoints or cloud environments, Murphy said at the time.
“With consistent outperformance and a proven track record of serving many of the world’s largest enterprises, it’s clear that ReliaQuest’s AI-driven platform is uniquely positioned to empower customers with a best-of-breed approach towards cybersecurity, improving automation, operational efficiencies and, most critically, results,” FTV Capital Partner Kyle Griswold said in a statement.
ReliaQuest was recognized by Forrester in February as a strong performer in managed detection and response services, with the analyst firm praising the company for improving the security analyst experience and adding generative and agentic AI capabilities into GreyMatter. Forrester criticized ReliaQuest for weaker offerings around system criticality, vulnerability prioritization and security posture management.
