Yes. Sophos Fusion is open by design and integrates with more than 500 third-party security and IT technologies. Your existing endpoint, firewall, and identity tools can feed into the shared data layer.

How does Fusion handle AI-driven threats?

Fusion uses agentic AI to investigate and respond at machine speed, with human oversight for governance. AI handles 52% of cases autonomously, and average alert-to-response time is 89 seconds.

What does "AI-native" actually mean?

It means AI is the architecture, not an add-on. The system is built from the ground up so AI connects products, data, and responses. Every control point and service operates in a unified way.
