Microsoft Defender Suite for Business Premium: what you get, and who it’s for

1 November 2026 · Shlomi Fanan

Licensing

Business Premium gives you a solid security baseline. Defender Suite adds the tools to detect and investigate an attack that gets past it.

Who it’s for

Who it’s too early for

If Business Premium isn’t fully deployed yet, for example Conditional Access, Intune and Defender for Business aren’t configured, start there. Most attacks are stopped at that layer, and Defender Suite won’t make up for a missing baseline.

What it costs

Prices vary by provider and terms, so get a current quote. The add-on is also available for Business Premium for nonprofits. There is also a version that combines Defender and Purview: Microsoft Defender and Purview Suites for Business Premium.

Where to start

  1. Make sure the Business Premium baseline is in place: Conditional Access, Intune and Defender for Business.
  2. Decide what you need: on-premises AD, phishing simulations, risk-based policies or cloud app control.
  3. Plan who will use the tools: an internal team or a monitoring provider.
  4. Get a quote and compare it with the separate tools you already pay for.
