LevelBlue to Acquire Trustwave to Create Major MSSP

LevelBlue has announced plans to acquire Trustwave to create the largest pure-play managed security services provider (MSSP).

LevelBlue announced on Tuesday that it’s acquiring managed detection and response (MDR) services company Trustwave from The Chertoff Group’s MC² Security Fund.

LevelBlue, formerly known as AT&T Cybersecurity, was launched in May 2024 as a joint venture between WillJam Ventures and AT&T. 

The company’s acquisition of Trustwave comes shortly after it announced plans to buy Aon’s cybersecurity consulting business. The deals are part of a plan to become the largest pure-play managed security services provider (MSSP). 

Once the acquisition has been completed, LevelBlue’s expertise in strategic risk management and cybersecurity infrastructure will be integrated with Trustwave’s platform and MDR service.

“The merged capabilities provide enterprises with unprecedented visibility and control over how security resources are provisioned, monitored, and managed across any environment, strengthening overall cyber resilience,” the companies said.

SecurityWeek has been told that the two companies are in early integration stages, but will eventually combine into a single company.

Financial terms of the acquisition have not been disclosed. 

SecurityWeek has been monitoring mergers and acquisitions in the cybersecurity space and this year we have added over 200 deals to our M&A tracker. More than 50 deals involved MSSPs, but only half of them are pure-play MSSPs.

More than 400 cybersecurity mergers and acquisitions were announced in 2024, according to a SecurityWeek analysis.
