Randomized Controlled Trials for Microsoft Copilot for Security. SSRN Working Paper 4648700. With James Bono, Sida Peng, Roberto Rodriguez, and Sandra Ho.
We conducted randomized controlled trials (RCTs) to measure the efficiency gains from using Security Copilot, including speed and quality improvements. External experimental subjects logged into a M365 Defender instance created for this experiment and performed four tasks: Incident Summarization, Script Analyzer, Incident Report, and Guided Response. We found that Security Copilot delivered large improvements on both speed and accuracy. Copilot brought improvements for both novices and security professionals.
