LevelBlue has completed its acquisition of Trustwave, establishing itself as the world’s largest pure-play managed security services provider (MSSP). This strategic move, announced on August 19, 2025, combines LevelBlue’s AI-driven security expertise with Trustwave’s market-leading managed detection and response (MDR) capabilities, creating a comprehensive cybersecurity portfolio to address evolving threats across enterprises and government agencies.

Aims to reduce cyber risk and enhance resilience for global clients.
The acquisition unites LevelBlue’s expertise in network security and threat intelligence with Trustwave’s strengths in MDR, offensive security, and the elite SpiderLabs team. “The acquisition of Trustwave makes us the most complete cybersecurity partner in the industry,” said Bob McCullen, Chairman and CEO of LevelBlue. “We’re redefining what it means to be a managed security provider—combining world-class human expertise with AI-powered, platform-led services to give clients faster detection, smarter response, and long-lasting resilience against evolving threats.” This merger creates a unified platform that simplifies operations and optimizes protection across cloud, on-premises, and hybrid environments.
LevelBlue’s expanded ecosystem integrates its Open Threat Exchange (OTX), the world’s largest open threat-sharing platform, with Trustwave’s proprietary detection logic and SpiderLabs’ research capabilities. This combination delivers superior situational awareness, enabling faster threat detection, reduced alert fatigue, and proactive mitigation. “LevelBlue’s acquisition of Trustwave, on the heels of the Stroz Friedberg transaction, marks a pivotal moment in cybersecurity, delivering a very broad portfolio of capabilities among pure-play services providers,” said Craig Robinson, IDC Research Vice President for Security Services. The synergy enhances enterprise and government cybersecurity resilience.
Trustwave’s status as the first pure-play MDR provider to achieve full Federal Risk and Authorization Management Program (FedRAMP) and StateRAMP authorizations enhances LevelBlue’s ability to serve critical sectors. These credentials ensure compliance with stringent U.S. Department of Defense and government requirements, providing streamlined procurement and mission-critical resilience. This capability positions LevelBlue to meet the needs of federal, state, and local government agencies, as well as the Defense Industrial Base, with robust cybersecurity solutions.
The Trustwave acquisition follows LevelBlue’s recent purchase of Aon’s Cybersecurity and Intellectual Property Litigation consulting groups, including Stroz Friedberg and Elysium Digital. These consolidations address the growing demand for integrated, adaptive cybersecurity solutions. IDC research indicates that 36% of organizations are significantly increasing cyber-resilience spending in 2025, reflecting the need for mature security frameworks. LevelBlue’s comprehensive portfolio, including MDR, AI-driven threat detection, and strategic advisory, supports this shift toward proactive resilience.
