Microsoft Defender for Business — Free 30-Day Trial

Microsoft’s current Defender page offers a free 30-day trial of Microsoft Defender for Business. The service is designed for small and medium organizations and the checked page states support for up to 300 users and up to five devices per user, with protection across supported Windows, macOS, iOS and Android devices. The trial is an evaluation of a paid security product rather than a permanent free entitlement. Organizations should review the current trial terms and deployment requirements before onboarding devices or relying on the evaluation for ongoing security operations.
