Overview
LevelBlue, headquartered in Dallas, describes itself as the world’s largest pure-play managed security services provider, a position it built through acquisitions in 2025[28]. It completed the purchase of Trustwave on 19 August 2025 and of Cybereason on 25 November 2025, after earlier deals for Stroz Friedberg and Elysium Digital; the Cybereason transaction also brought SoftBank Corp., SoftBank Vision Fund 2 and Liberty Strategic Capital in as investors[28][29]. LevelBlue does not publish a total headcount; its SpiderLabs unit alone is described as a global team of more than 1,000 consultants, threat hunters and incident responders[27], the figure used for ranking.
