Sophos cuts threat investigation time by 96% with OpenAI Daybreak

Sophos, the British cybersecurity firm, has incorporated OpenAI’s generative AI tool Daybreak into its managed detection and response (MDR) platform. According to the company’s announcement, the integration cuts the time required to investigate security incidents by 96 %, reducing the process from minutes or even hours to just a few seconds. The Daybreak‑driven automation handles roughly half of the cases that previously demanded manual intervention, achieving a 52 % automation rate while still retaining human oversight. The solution relies on the model’s ability to sift through large volumes of log data, correlate indicators of compromise, and produce clear reports that analysts can quickly validate. Sophos stresses that the AI does not replace experts; it serves as an assistant that speeds up triage and frees staff to focus on more complex threats. The company also notes that result accuracy remains high thanks to ongoing review and refinement processes. This operational improvement translates into a faster response to attacks, reducing client exposure to risk. The story is significant because it shows generative AI moving from experimental use to a core component of cyber defense, giving organizations a more efficient and scalable way to protect their infrastructure.
