Enterprise-grade security for Business Premium: Defender Suite and Purview Suite

Businesses with up to 300 users can now get E5-level security and compliance – without switching licenses.

· 2 min read

Three new add-ons

Since September 2025, Microsoft has offered three add-ons for Business Premium: Defender Suite for advanced threat protection, Purview Suite for data governance and compliance, and a combined bundle with both. List prices are $10 per user for each suite and $15 for the combined bundle.

Microsoft also changed the names at the same time: Microsoft 365 E5 Security is now called Microsoft Defender Suite, and E5 Compliance is called Microsoft Purview Suite.

What do you get?

Defender Suite includes Defender for Endpoint Plan 2, Defender for Identity, and XDR across identity, devices, email, and cloud services, among other capabilities. Purview Suite includes DLP, sensitivity labels, eDiscovery Premium, and Insider Risk Management, among others.

Good to know

Mixed licensing is not supported for endpoint protection: If some users have Defender for Business and others have Defender for Endpoint Plan 2, everyone falls back to Defender for Business.

What we recommend

  • Consider the combined bundle if you need both
  • License all users the same way for endpoint protection
  • Plan the configuration – the value is in the setup
