Sophos Says OpenAI's Daybreak Slashed Threat Investigation Time by 96%

Sophos reports that using OpenAI's Daybreak cut cyber-threat investigation time by 96% and automated 52% of its MDR cases, with humans still overseeing.

October 9, 2026

OpenAI has published a customer story describing how security company Sophos uses Daybreak, an OpenAI offering, to speed up the investigation of cyber threats. According to the source, the company cut the time needed to investigate threats by 96%.

The same account says 52% of Sophos’s managed detection and response (MDR) cases are now automated. The source stresses that human oversight is preserved, meaning the automation is described as working alongside security staff rather than replacing them. The source text is brief and does not detail how Daybreak works or how the figures were measured.

Why it matters

  • Security teams could see faster investigations, since the reported time savings reach 96% in this case.
  • Automating about half of MDR cases (52%) points to how AI may take on routine security work at scale.
  • The emphasis on human oversight signals that companies adopting AI in security are still keeping people in the loop.
  • Note that these figures come from OpenAI’s own customer story, so results may vary elsewhere.
