The companies announced a definitive agreement on October 14, 2025; that earlier date was the announcement, not the closing. They have not disclosed the purchase price.
When did LevelBlue acquire Cybereason?
LevelBlue announced the agreement on October 14, 2025, then announced that the acquisition was complete on November 25, 2025. The two dates mark distinct stages of the transaction, not competing reports. LevelBlue’s agreement announcement and its completion announcement document the timeline.
The deal followed a change in public position. On March 7, 2025, LevelBlue said it would no longer merge with Cybereason. The companies later agreed to an acquisition, which closed in November. The announcements establish that sequence but do not explain why negotiations resumed or what changed. LevelBlue’s March 7 statement records the earlier position.
What were the financial terms?
The companies did not disclose the acquisition’s financial details in LevelBlue’s October agreement announcement. No purchase price or transaction valuation is established by the reviewed company announcements, so estimates should not be treated as confirmed consideration.
#1 Best Overall
For perspective only, Clairfield International’s March 2026 cybersecurity sector report put total cybersecurity exit value in 2025 at US$72.6 billion, including signed transactions that had not yet closed. That is an industry-wide figure, not the LevelBlue–Cybereason deal value. Clairfield International’s report also describes managed-security acquisitions as part of a broader consolidation trend.
What did each company bring to the combination?
LevelBlue described the acquisition as combining its managed detection and response (MDR), managed security and broader cybersecurity services with Cybereason’s extended detection and response (XDR), threat intelligence, and digital forensics and incident response (DFIR) capabilities.
LevelBlue also cited consulting, offensive security, penetration testing, risk assessment, detection engineering, monitoring and technology-agnostic integration. These describe the company’s stated strategic rationale and service capabilities; they do not establish independently measured results from integrating the businesses.
What changed for investors and leadership?
In its completion announcement, LevelBlue said SoftBank Corp., SoftBank Vision Fund 2 and Liberty Strategic Capital became investors in LevelBlue as part of the transaction. Steven T. Mnuchin, Liberty Strategic Capital’s managing partner and a former U.S. Treasury Secretary, joined LevelBlue’s board. The announcement did not specify individual investment amounts or ownership stakes.
Rank #3
What is known about the deal’s impact?
LevelBlue said the acquisition expands its presence in North America, Europe and Asia, particularly Japan, and described Cybereason as among the leading cybersecurity providers in Japan. That market characterization is LevelBlue’s, not an independently established ranking in the announcements.
The completion announcement does not quantify realized integration benefits, customer retention, headcount changes or revenue contribution. The strategic benefits and combined capabilities described by the company should therefore be read as its stated rationale, not proof of post-close performance.
In the completion announcement, LevelBlue Chairman and CEO Bob McCullen said the deal brings together “unmatched XDR, MDR, and DFIR capabilities, powered by AI and elite human expertise.” That is his characterization of the combination, not an independent assessment of its performance.

Clairfield International’s March 2026 report says acquisitions of managed security service providers can help consolidators broaden their offerings, reach additional client verticals and build end-to-end security operations. It links demand for outsourced security to talent shortages, cloud complexity and rising threats. This provides industry context; it does not establish that these were the only drivers of LevelBlue’s specific acquisition.
