Sophos Fusion integrates natively with Sophos solutions and 500+ third-party technologies.[1][10]

Fusion AI is the intelligence layer within Sophos Fusion, and Sophos says human experts remain accountable. Sophos says every new threat seen across the 625,000+ organizations it defends elevates protection for all, automatically. Sophos says its solutions stop AI- and human-led threats before they can impact a business. Sophos takes a prevention-first approach, blocking ransomware, phishing and credential-based attacks before they spread. Sophos describes capabilities to discover and manage AI usage across an organization and reduce AI-driven risk.

On the network side, Sophos says its next-gen firewalls serve distributed and growing enterprises with the most complex networks.

All 2U rackmount models are powered by a high-speed CPU plus an Xstream Flow processor for traffic acceleration.

Maximum port density is 48 on the XGS 5500, 68 on the XGS 6500, or 70 on the XGS 7500/8500 using optional modules. Sophos says Flexi Port modules let customers adapt an appliance rather than purchase new hardware mid-term. Sophos describes sufficient headroom for key threat protection features such as TLS inspection, sandboxing, and AI-driven threat analysis. All 2U rackmount appliances are supplied with rackmount sliding rails.[11]
