Microsoft 365 Business Premium vs Business Standard: Which Plan Do You Need?

The difference between Microsoft 365 Business Premium and Business Standard comes down to one thing: security and device management. Both give you the Office apps, email, Teams, and SharePoint. Business Premium adds Microsoft Defender for Business, Intune device management, and Entra ID P1 conditional access on top. For most Australian SMEs holding client data, Premium is worth the extra few dollars per user, and the gap is shrinking from 1 July 2026.

Key facts

• Business Standard and Business Premium share the same Office apps, email, Teams, and SharePoint.
• Business Premium adds Microsoft Defender for Business, Intune, and Entra ID P1 conditional access, which Standard does not include.
• Business Premium is around AU$32.90 per user per month ex GST and its price is holding while Business Standard rises from 1 July 2026.
• Both plans support up to 300 users; larger organisations move to enterprise plans.
• Buying Defender and device management separately costs more than the gap between Standard and Premium.

What do Business Standard and Business Premium have in common?

Business Standard and Business Premium share the entire productivity layer: the desktop, web, and mobile Office apps, Exchange email with a custom domain, Microsoft Teams, SharePoint, OneDrive, and the core collaboration tools. If your only interest is staff being able to write documents, send email, and meet in Teams, the two plans look identical, and Standard would do the job.

Both are capped at 300 users, and both store Australian tenants' data at rest in Microsoft's Australian data centres. So the question is never about productivity features, because those are the same. It is entirely about what Premium adds on the security and management side.

What does Business Premium add over Standard?

Business Premium adds three things Standard lacks: Microsoft Defender for Business, Intune, and Entra ID P1. Defender for Business brings real endpoint detection and response plus Safe Links and Safe Attachments for email, going well beyond the basic filtering in Standard. Intune lets you manage and secure every device from one dashboard, including remote wipe. Entra ID P1 unlocks conditional access.

Conditional access is the one worth understanding, because it is the control that changes your security posture most. It is what lets you set a rule like "staff can open company email, but only from a device enrolled in Intune that has a screen lock and encryption." Without it, any password that leaks is a way in; with it, a leaked password alone is not enough. That single capability is often the reason a business should be on Premium.

Which plan does your business actually need?

If you hold client data, have any compliance obligation, or run staff on their own laptops and phones, you need Business Premium. If you are a very small team doing low-sensitivity work, with no regulatory exposure and company-owned devices you trust, Business Standard may genuinely be enough. The deciding question is how much it would hurt if a staff device or account were compromised.

The pricing change makes the call easier. Business Standard is rising from 1 July 2026 while Business Premium holds at around AU$32.90 per user per month, so the gap between them is narrowing to only a few dollars per user. When that small a difference buys an entire security and device-management stack, paying it is usually the obvious move. We cover the setup side in our Microsoft 365 Business Premium service.

Frequently asked questions

Is Business Premium worth the extra cost?

For most businesses that hold client data or run staff on mobile and home devices, yes. The extra cost over Standard buys Defender for Business, Intune device management, and conditional access, which would cost more purchased separately. With the price gap narrowing in July 2026, Premium has become better value than it was, and for many SMEs it is the most cost-effective security option available.

Can I mix Business Standard and Business Premium in one tenant?

Yes. You can assign different plans to different users in the same tenant, which is often the smart approach. Staff handling sensitive data or working on their own devices get Premium, while some lower-risk or shared-device roles may suit Standard. Right-sizing licences this way avoids paying for capability that certain roles do not need.

Does Business Standard include any security at all?

Yes, but only the basics. Business Standard includes Exchange Online Protection, which provides standard anti-spam and anti-malware filtering for email. What it lacks is endpoint detection and response, device management, and conditional access. So it is not unprotected, it just stops at the perimeter rather than securing devices and identity the way Premium does.

What happens to our price at the July 2026 changes?

Business Premium pricing is holding, while Business Basic and Business Standard are rising. Existing customers stay on their current pricing until their next renewal after 1 July 2026, with Microsoft committing to at least 30 days' notice. It is worth checking your renewal date and reviewing whether your plan mix still makes sense before then.

If you are weighing up Standard against Premium, or wondering whether your current plan mix still makes sense before the July 2026 changes, that is worth a quick look. We are happy to review what you are licensed for and recommend the right plan for each role.
