Microsoft Defender for Business (MDB) is an anti-malware solution for devices across several operating systems – including Android, iOS, macOS, and Windows. It seeks to achieve the early detection and prevention of cyberattacks. MDB is available for both new and existing Microsoft 365 Business Premium subscribers.

There is a range of features, including enterprise-level security:

  • Automated investigation feature
  • Attack surface reduction
  • Anti-spam and antimalware protection
  • Anti-virus for Windows 10 and following editions
  • Centralized management and reporting
  • Endpoint detection & response – an ‘endpoint security system’
  • Email Protection
  • Vulnerability and threat management


  • Minimized risk of cyber attacks
  • Protection from business interruption caused by cybercrime and hacking
  • Suspicious activity is flagged automatically, catching potential cybercrime before it manifests
  • It’s easy to use with a simplified configuration
  • It’s charged per user, not the device.
  • Lastly, it protects systems of business owners from cybercriminals

Further, Microsoft 365 Business Premium is an all-in-one productivity and security offering, designed to help SMBs run their business in the new hybrid work world, with peace of mind. Also, it brings together your favorite collaboration solutions like Microsoft Teams and Office along with comprehensive security. The addition of MDB further strengthens Business Premium’s existing offering by adding cross-platform endpoint protection for Windows, macOS, iOS, and Android. As a result, it elevates endpoint security against sophisticated ransomware attacks through enterprise-grade technologies like Endpoint Detection and Response (EDR) and Automated Investigation and Remediation. What’s more, Microsoft 365 Business Premium provides SMBs with an easy-to-use, comprehensive, and cost-effective package. Thus, eliminating the need for managing multiple-point solutions, and saving time and money.

Finally, Microsoft has not released the “standalone” version of MDB at this point (just the one bundled in Microsoft 365 Business Premium).
