LevelBlue Acquires Trustwave, Forms World’s Largest Independent MSSP

In a significant move within the cybersecurity sector, LevelBlue, a business spun out of AT\&T in 2024, has announced its acquisition of Trustwave, a cybersecurity giant previously owned by The Chertoff Group MC2 Security Fund. This acquisition, which remains undisclosed in terms of financial details, positions the combined entity as the world’s largest independent Managed Security Services Provider (MSSP), offering a range of services, including cyber consulting, managed detection and response, and incident response services.

the Acquisition

The merger between LevelBlue and Trustwave comes on the heels of another major acquisition by LevelBlue, that of Aon’s Cybersecurity and Intellectual Property Litigation consulting groups, including renowned names like Stroz Friedberg and Elysium Digital. This will further bolster LevelBlue’s already impressive portfolio. The deal, set to close by the end of the month, promises to generate annual revenues of over \$1 billion, servicing approximately 30,000 customers.

With the acquisition, LevelBlue will integrate Trustwave’s Fusion platform—a cloud-native security solution designed for unified security operations—into its cybersecurity infrastructure. Trustwave’s Fusion, an analytics tool and data lake, offers centralized visibility of an organization’s entire security environment and enhances incident detection and response capabilities. The addition of Trustwave will also expand LevelBlue’s customer base and geographic footprint, with a focus on international expansion into markets like the UK, Australia, and Japan.

However, this acquisition follows a failed merger between Trustwave and Cybereason, which fell apart in late 2024 due to internal conflicts. Despite this setback, Trustwave’s existing partnership with Cybereason will remain intact. Robert McCullen, LevelBlue’s chairman and CEO, expressed excitement about reuniting with Trustwave, having led the company for nearly a decade before it was sold to SingTel in 2015. This acquisition, he notes, feels like a homecoming.

What Undercode Says:

The strategic acquisition of Trustwave by LevelBlue is a significant turning point in the cybersecurity industry, particularly for the MSSP market. The merging of LevelBlue’s risk management infrastructure with Trustwave’s advanced security operations tools like the Fusion platform has the potential to create a cybersecurity powerhouse capable of addressing increasingly complex threats across industries.

The shift to cloud-native security platforms, such as Trustwave’s Fusion, is an industry-wide trend. Businesses are looking for integrated solutions that offer real-time monitoring, threat detection, and automated response, which are all essential for managing the evolving cyber threat landscape. By acquiring Trustwave, LevelBlue is positioning itself at the forefront of this movement, with a unique edge in providing tailored cybersecurity strategies for global enterprises.

Moreover, LevelBlue’s geographic expansion, particularly into the UK, Australia, and Japan, shows that the company is serious about its international growth ambitions. Entering these markets will not only increase its customer base but will also allow it to leverage global security insights and technologies.

This acquisition also reflects a broader trend of consolidation in the cybersecurity industry, as companies look to scale their operations and offer end-to-end services to clients. LevelBlue’s ability to integrate disparate cybersecurity solutions into a unified platform will be a key differentiator, setting it apart from competitors in the MSSP space.

One key takeaway here is the merging of two significant entities with complementary strengths. LevelBlue’s expertise in managed security services and Trustwave’s deep knowledge in threat intelligence and security research create a synergy that will benefit both companies and their clients.
