OpenAI publishes Sophos case study for Daybreak, claiming 96% faster threat investigations and 52% of MDR cases automated
Announced October 9, 2026
What happened
OpenAI published a case study on its official blog about security company Sophos's use of OpenAI Daybreak. According to the post, Sophos used Daybreak to cut cyber threat investigation time and automatically handle some MDR (managed detection and response) cases while keeping human oversight. The summary does not state the measurement conditions or time period.
Provider claims
96% reduction in threat investigation time and 52% of MDR cases automated (OpenAI customer case claim; measurement conditions not disclosed).
Why it matters
This is an official example of how many real cases an AI agent handles in security operations under human supervision. Anthropic also recently launched a program to support defenders, and competition between the two companies in cyber defense is becoming clearer.
