U.S.-based cybersecurity firm ReliaQuest has secured a significant funding boost with a new investment round totaling over $500 million, elevating the company’s valuation to $3.4 billion. The funding round was led by global investors EQT Partners, KKR, and FTV Capital, alongside existing investors Ten Eleven Ventures and Finback Investment Partners.

This fresh capital injection underscores ReliaQuest’s ambition to enhance and expand its GreyMatter platform globally. Founded in 2007 by Brian Murphy, ReliaQuest specializes in leveraging artificial intelligence to bolster enterprise security operations, enabling clients to detect, respond to, and mitigate cyber threats rapidly and efficiently.

GreyMatter, ReliaQuest’s flagship product, integrates with over 200 cybersecurity tools, offering organizations the flexibility and sophistication needed to navigate complex digital threat landscapes. The platform’s reliance on “Agentic AI,” which autonomously learns and responds to emerging cyber threats, is reported to increase investigation speed by 20-fold while improving accuracy by 30% compared to traditional methods.

ReliaQuest’s customer portfolio is diverse, including major enterprises like Southwest Airlines and Campbell Soup Company. The firm claims that its AI-powered capabilities enable security teams to contain threats in under five minutes, a critical advantage as threat actors reportedly move within networks in under an hour.

With the sustained investor interest in AI enhancements and security innovations, Murphy, supported by the company’s invested partners, expressed optimism toward ReliaQuest’s future as a frontrunner in delivering technologically advanced cybersecurity operations to complex enterprise environments.

“Enterprise security teams have more data in more places than ever before, and the speed of the threat is rapidly increasing. CISOs need a way to contain threats within minutes without added cost or technical overhead, leveraging the latest innovations in Agentic AI,” Murphy said in a release. “This new investment is a key step along our growth trajectory as a company, but most importantly it will allow us to deliver better security outcomes for even more CISOs around the world.”
