Microsoft Defender for Business is available embedded in Windows 10/11. Users can start using it by applying Windows Update.

The function of the EDR tool is also included in the “Microsoft 365 Business Premium” license, and this time, the function of the EDR can be purchased separately.
Microsoft points out that it is difficult to prevent unknown viruses such as ransomware only with antivirus software aimed at protection before virus invasion as a background to provide the EDR function as a tool. “The number of viruses that slip through antivirus software and invade is increasing. EDR, which can detect, respond to, and repair such attacks, complements the functions of existing antivirus software,” the company said.
