Sophos Unveils AI-Native Fusion Cybersecurity Defense System

Sophos

Sophos has launched Fusion, an AI-native cybersecurity defense system that unifies security operations, helping organizations prevent, detect and respond to increasingly sophisticated AI-driven cyber threats faster.

Sophos has introduced Sophos Fusion, describing it as the industry’s first and most comprehensive AI-native cybersecurity defense system designed to help organizations combat increasingly sophisticated AI-powered cyber threats.

The new platform combines security operations, endpoint protection, network security, identity, email and cloud security into a single defense system capable of preventing, detecting, investigating and responding to attacks in real time.

According to Sophos, modern cyberattacks now move across enterprise environments much faster than before, reducing the time between initial compromise and business impact from days to just hours. The company said many organizations continue to rely on dozens of disconnected security products, creating operational complexity and slowing incident response.

AI-Native Fusion

Sophos Fusion operates on a unified architecture that integrates native Sophos technologies with more than 500 third-party security tools. The platform uses a shared data layer, synchronized security controls and agentic artificial intelligence to automate threat investigation and response while allowing human oversight.

The company said Sophos Fusion builds on Sophos Central, which currently serves more than 625,000 organizations worldwide, and incorporates Secureworks Taegis analytics following Sophos’ acquisition of Secureworks in 2025.

Sophos also highlighted its operational experience, noting that its security operations centre supports over 40,000 managed detection and response customers. According to the company, AI now resolves 52% of security cases automatically, while the average time from alert to a fully automated response is 89 seconds.

Beginning between August and October 2026, Sophos will expand Fusion with several new capabilities, including Next-Gen SIEM, AI Defense, CISO Advantage, enhanced Managed Detection and Response (MDR), and an upgraded Extended Detection and Response (XDR) platform powered by Secureworks analytics.

Sophos said the expanded platform will also strengthen its global ecosystem of managed service providers, security partners and resellers by enabling them to deliver integrated cybersecurity services while improving protection for customers against evolving AI-driven threats.
