Microsoft will enable fully automated threat remediation by default for Microsoft Defender for Endpoint customers who have opted into public previews starting next month. Microsoft found that organizations using full automation by default were more successful in remediating and containing threats. Microsoft has increased malware detection accuracy, upgraded its automated investigation infrastructure, and added an option to undo remediation actions. The default automation level from Semi to Full will be enabled on public preview customers starting on February 16, 2021. Microsoft’s endpoint security platform has expanded to include non-Windows platforms in June.
