The company said the capital will be used to drive product innovation, including AI security capabilities, and to support continued global expansion; it also highlighted a new U.K. office in Reading. ThreatLocker is a zero trust cybersecurity company based in Orlando. The round was framed as part of its next phase of growth, with the company saying the investment will accelerate innovation across its Zero Trust Platform, expand protection against AI-related security risks, and support faster international growth. One report said the company’s valuation was not disclosed in connection with the round, but that it had previously been valued at USD 1.6 billion and that the new valuation “significantly grew.” Public reporting also described ThreatLocker as serving more than 70,000 organizations and noted that the business has continued to attract repeat support from existing investors while adding Koch Disruptive Technologies as a new backer.

This followed earlier rounds including a $115 million Series D in April 2024 led by General Atlantic with StepStone Group and D.E. Shaw Group, bringing total funding over $200 million. The Series E funds are allocated to expand security platform capabilities, grow engineering and security teams, scale enterprise adoption, enhance cybersecurity solutions, support acquisitions, and position for potential IPO within 2-3 years.
