KKR, a global investment firm, has led a new funding round in ReliaQuest, a provider of open XDR-as-a-service. The funding round also included Ten Eleven Ventures, FTV Capital and founder Brian Murphy.

The funding round followed a previous $300 million growth equity round in 2020 that accelerated the expansion of ReliaQuest’s operations and its Grey Matter platform. ReliaQuest offers outcomes and board-ready reporting used by organizations to solve cybersecurity challenges. The Grey Matter platform is a 24/7/365 service that delivers unified detection and response with transparency and automation.

KKR makes the investment through its Next Generation Technology Growth Fund II, dedicated to investment opportunities in technology.

“Over the past several years, we’ve seen ReliaQuest evolve its solution into a leading platform that is highly capable of solving security challenges for organizations across industries and geographies,” said Stephen Shanley, managing director at KKR.
