Case reports average response time of 89 seconds and 52% of MDR cases resolved end-to-end by agents. Understand how to validate defensive automation.
Direct answer
On October 9, 2026, OpenAI published that Sophos reduced threat investigation time by 96% using OpenAI Daybreak. The case reports an average response of 89 seconds and end-to-end AI resolution in 52% of Managed Detection and Response cases. These results depend on Sophos scope, data, playbooks, and oversight; Enterprise adoption requires comparing accuracy, coverage, undue containment, and human escalation time.
Speed needs to preserve evidence
A rapid investigation must maintain artifacts, timeline, sources, actions, and justifications for auditing and learning.
End-to-end automation demands limits
Define which actions can be performed, which require approval and which should only be recommended.
False positive has operational costs
Blocking a legitimate account, host, or traffic can disrupt your business. Measure accuracy by severity and impact of containment.
Human scaling remains essential
Ambiguous cases, new standards, and critical assets need experts with context and authority.
