Security operations company ReliaQuest LLC announced today that it has raised more than $500 million in new funding on a $3.4 billion valuation to advance agentic AI-driven cybersecurity automation and support the company’s ongoing international expansion.
Founded in 2007, ReliaQuest is a cybersecurity technology company that specializes in enhancing enterprise security operations. The company has as its mission to “make security possible” by providing organizations with increased visibility and the ability to confidently automate across the security lifecycle.
ReliaQuest’s main product, GreyMatter, is a technology-agnostic security operations platform that was built on an open extended detection and response architecture.
GreyMatter integrates with more than 200 different cybersecurity and enterprise tools to deliver threat detection, investigation and response across complex information technology environments. The platform allows security teams to detect, contain, investigate and respond to cyberthreats across a variety of solutions within minutes, all while eliminating the most mundane work and delivering more value from existing investments.
The agentic AI models in GreyMatter can operate and learn autonomously, addressing security challenges by automating security processes and significantly reducing the time to contain threats. ReliaQuest claims that using GreyMatter’s automation and AI capabilities, customers can perform investigations 20 times faster and with 30% greater accuracy than traditional methods, containing threats within less than five minutes and allowing security teams to focus on higher-level business needs rather than mundane tasks.
ReliaQuest counts among its customers Southwest Airlines Co., Campbell Soup Company, Abercrombie & Fitch Co., Darden Restaurants Inc., Hanesbrands Inc., Boston Celtics and APi Group Corp.
The funding round was led by EQT Partners AB, Kohlberg Kravis Roberts & Co. L.P. (KKR) and FTV Capital, with existing investors Ten Eleven Ventures and Finback Investment Partners also participating.
“Everything we have done at ReliaQuest has always been driven by the problem we solve for our customers,” said ReliaQuest founder and Chief Executive Brian Murphy said in a statement. “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.””
