OpenAI published a customer story on October 9, 2026, saying Sophos cut threat investigation time by 96% with agents built through OpenAI Daybreak. That headline is OpenAI's framing of a time cut on the cases those agents handle. It is not an independent audit. Sophos chief technology officer John Peterson, quoted in the story, said the average response time for cases using the Daybreak-built agents has fallen to about 89 seconds. Before Daybreak, investigating and responding depended primarily on human expertise, and Sophos's existing process averaged around 38 minutes. OpenAI's results box states the comparison as a drop from approximately 38 minutes to 89 seconds and calls it a 96% reduction in investigation time using OpenAI models. That 96% is not the only one in the story, and the two should not be read as the same claim. Peterson also said the prior 38-minute average was better than 96% of professional security operations centers. One figure is OpenAI's description of how far the agent-handled average fell. The other is his comparison of the old human-led average with other SOCs. ## What the agents handle The work sits in Sophos Fusion, which the OpenAI story calls Sophos's AI-native cyber defense system and which includes Sophos Managed Detection and Response. Fusion brings together sensor data from more than 500 third-party integrations alongside Sophos's own products. Those sensors generate trillions of events every day. Sophos distills them into roughly 1,000 to 2,000 cases for nine security operations centers to investigate. For each case, an investigation agent gathers customer context, detections, indicators of compromise, and relevant threat intelligence. A planning model then runs a plan-execute-review loop: it builds an investigation plan, completes the steps, and produces a summary with recommended response actions for analysts to review. Other agents can carry out parts of the response. OpenAI's results summary says this lets Sophos resolve 52% of MDR cases end-to-end with AI, within boundaries calibrated by Sophos analysts. Peterson described the share in related but not identical terms: about half of the cases Sophos handles are now automated by agents developed using the Daybreak models. ## Where a person still decides Customer control in the MDR service has three modes, and the same boundaries apply whether a person or an agent completes the work. Under Notify, Sophos investigates and recommends a response, but the customer acts. Under Collaborate, Sophos and the customer work together before action is taken. Under Authorise, Sophos can respond directly on the customer's behalf. Potentially destructive actions still require the right level of human oversight. "Anything we don't feel comfortable with an agent handling gets passed off for human judgement," Peterson said. OpenAI also says the setup helps Sophos scale compute rather than relying on equivalent growth in scarce cybersecurity headcount, and returns analysts' attention to the threats, exceptions, and decisions where their expertise matters most. ## A recap, not a second clock Unite.AI's article on the October 9 story repeats the same figures. The site describes that piece as AI-generated and reviewed by its editorial team. It does not publish a separate measurement. It does add earlier partnership context. According to Unite.AI, Sophos announced on June 22, 2026, that it had joined the OpenAI Daybreak Cyber Partner Program and was adopting the capability in a deliberate, phased way, beginning with defensive workflows and scoped outputs, with analysts and controls in the loop rather than direct customer access to the models. Unite.AI reports that the June announcement already described Sophos MDR as resolving 52% of cases end-to-end with AI, with an average response time of 89 seconds. The same recap says that on August 10, 2026, Peterson wrote that the companies were extending the work to the channel through Sophos Fusion, still with expert operators in control and no direct customer access to the models. Sophos protects more than 625,000 organizations, the OpenAI story says. Peterson said response capabilities will keep becoming more sophisticated and that Sophos will broaden the use cases the agents address. The narrower claim is the one that matters for operations: OpenAI says 52% of MDR cases are resolved end-to-end inside bounds analysts calibrate, and Peterson says anything the team is not comfortable handing to an agent still goes to a person. Read OpenAI's October 9 customer story for the quoted times, the results box, and the handoff line. Treat the Unite.AI article as a recap of that story and of the June and August partnership timeline, not as an independent check on either 96% figure. ## Sources - [Sophos cuts threat investigation time by 96\% with OpenAI Daybreak](https://openai.com/index/sophos/) - [Sophos Says Daybreak AI Agents Cut Average Case Response to 89 Seconds](https://www.unite.ai/sophos-says-daybreak-ai-agents-cut-average-case-response-to-89-seconds/)
