Sophos sells endpoint, firewall, email, and cloud security plus a managed detection service its own analysts run, and Thoma Bravo has owned the British company since a 3.9 billion dollar take-private in 2020. It reaches midmarket buyers through resellers and managed service providers, a channel counted at more than 53,000 at its 2020 take-private, rather than a direct sales force. Independent labs rate its products as competitive rather than category-leading, with AV-Comparatives scoring its endpoint protection at 98.0 percent in late 2025, so its harder-to-copy advantage is that partner channel and its analyst-run services. Its 859 million dollar purchase of Secureworks in early 2025 added the Taegis platform and made managed detection the center of the business.
