What is Secureworks (a Sophos company)?

Secureworks pioneered the modern MSSP model and was majority-owned by Dell before its acquisition by Sophos in an $859M deal that closed February 2025. The Taegis platform (MDR, XDR, NDR, VDR, embedded SIEM) continues as a standalone, vendor-open product line within Sophos with native Sophos Endpoint integration. The Counter Threat Unit (CTU) remains a key differentiator.

Best for: Mid-to-large enterprises wanting a vendor-open MDR with strong threat intel and an embedded SIEM, especially in regulated verticals

Pros

✓ Counter Threat Unit is one of the longest-running in-house threat research teams
✓ Taegis remains vendor-open / BYO-EDR even post-Sophos
✓ Embedded SIEM removes the need for a separate Splunk-class deployment for many customers
✓ Deep history with regulated industries and global SOC footprint

Cons

✗ Ongoing integration risk following the Sophos acquisition
✗ Heritage SIEM/MSSP roots can mean a heavier deployment than newer cloud-native MDRs
✗ Limited public list pricing
