Enterprise anti-malware vendor Sophos on Monday announced plans to acquire SecureWorks in an all-cash deal valued at $859 million.

The Thoma Bravo-owned Sophos said SecureWorks shareholders (including Dell Technologies) will receive $8.50 per share, a 28% premium on Secureworks’ 90-day average price.  

The plan is to combine the Secureworks Taegis XDR platform with Sophos’ managed detection and response (MDR) services to tap into lucrative markets across small, mid-sized, and enterprise segments. 

Sophos, which maintains headquarters in the UK,  said the transaction brings new products to the table, including business tooling for identity detection and response (ITDR), next-gen SIEM capabilities, operational technology (OT) security, and enhanced vulnerability risk prioritization. 

The deal is expected to close in early 2025, subject to regulatory approval.

Last August, the Atlanta-based SecureWorks cut approximately 15% of its staff and announced “certain real estate‑related cost optimization actions”.

“Under the Plan, the Company intends to rebalance investments cross-functionally in alignment with the Company’s current strategy and growth opportunities, such as focusing on the higher value, higher margin Taegis solutions, optimizing the Company’s organizational structure to increase its scalability, and other priorities, to better position the Company for continued growth with improving operating margins over time,” SecureWorks said at the time.

The layoffs impacted staff in the US, UK, Japan, India, Australia, the Middle East, Romania and other European countries.
