ReliaQuest, a player in AI-powered security operations, announced a new funding round of more than $500M led by EQT (EQT), KKR (KKR) and FTV Capital, with participation from other existing investors Ten Eleven Ventures and Finback Investment Partners. The funding round brings ReliaQuest’s valuation to $3.4B. This new funding will support ReliaQuest’s continued growth, fueling further innovation in Agentic AI-driven cybersecurity automation and supporting the company’s ongoing international expansion. “Everything we have done at ReliaQuest has always been driven by the problem we solve for our customers.

CISOs need a way to contain threats within minutes without added cost or technical overhead, leveraging the latest innovations in Agentic AI,” said Brian Murphy, ReliaQuest founder and CEO. “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.”
