Microsoft 365 Business Standard vs Business Premium: what Australian SMBs actually get for the upgrade
Most Australian SMBs I talk to think Business Premium is "Standard with better apps". It isn't. The apps are the same. Word, Excel, Outlook, Teams, SharePoint, OneDrive and the mailbox you use every day don't change when you upgrade. What changes is how much control you have over who signs in, which devices touch company data, and what happens when something goes wrong.
That's worth paying for in some businesses and not in others. I help Australian SMBs work out which one they are, in plain English. Feature names match Microsoft Learn as of writing. Prices are Microsoft's direct list prices on microsoft.com/en-au at the time of writing (October 2026), ex GST. Check current pricing before you buy, because they move. Not legal advice.
What's the difference between Business Standard and Business Premium?
Same apps, different control. Premium is Standard plus a set of security and management products, in four areas:
- Who can sign in, and from where: Microsoft Entra ID P1, which gives you Conditional Access
- Which devices can touch company data, and whether you can wipe them: Microsoft Intune Plan 1
- Whether those devices fight back: Microsoft Defender for Business, plus Defender for Office 365 Plan 1 for email
- What happens to sensitive email and files: Microsoft Purview data loss prevention (DLP), sensitivity labels, encryption and archiving
| Feature | Business Standard | Business Premium |
|---|---|---|
| Apps, email, Teams, SharePoint, 1 TB OneDrive | ✓ | ✓ (same) |
| MFA for everyone | ✓ free, via security defaults | ✓, plus Conditional Access rules |
| Sign-in rules (e.g. only from managed devices) | ✗ | ✓ Conditional Access (Entra ID P1) |
| Phone management | Basic Mobility and Security (free, limited) | Intune Plan 1 (full device and app management) |
| Protect work data on staff-owned phones without enrolling them | ✗ | ✓ Intune app protection |
| Enforce BitLocker, recover keys, remote wipe for laptops | ✗ | ✓ Intune |
| New PCs shipped straight to staff (Autopilot) | ✗ | ✓ |
| Endpoint protection with detection and response | ✗ (not licensed for Defender for Business) | ✓ Defender for Business |
| Email threat protection | Exchange Online Protection + URL time-of-click protection | Defender for Office 365 Plan 1 |
| Stop sensitive data leaving by email, SharePoint or OneDrive | ✗ | ✓ Purview DLP |
| Label and encrypt client documents and email | ✗ | ✓ manual sensitivity labels + Message Encryption |
| Email archive | 50 GB archive (Exchange Online Archiving is an add-on) | Archiving included, auto-expanding to 1.5 TB |
| Backups | ✗ not included | ✗ not included either |
| Seat cap | 300 across the Business family | 300 across the Business family |
How much more does Business Premium cost in Australia?
At the time of writing (October 2026), on microsoft.com/en-au, ex GST, annual subscription paid yearly:
- Business Standard: AU$21.00 per user per month
- Business Premium: AU$32.90 per user per month
- The gap: AU$11.90 per user per month
On a monthly subscription it's AU$25.20 vs AU$39.48. These are Microsoft's direct web prices. If you buy through a partner or reseller (CSP), your price will be different, and existing customers usually stay on their current price until renewal. Check current pricing before you decide.
Do you need Premium for MFA?
No. This is the most common misconception I hear. Business Standard gets MFA for everyone for free through security defaults in Microsoft Entra ID. Security defaults require every user to register for MFA, require MFA for admins (and for users when Microsoft decides it's needed), and block legacy authentication.
What Premium adds is rules. Conditional Access lets you say things like "only allow sign-ins from our managed devices", "require MFA off-site" or "keep the break-glass admin account out of this policy". Security defaults are all-or-nothing. Conditional Access is configurable.
One trap: you have to turn security defaults off before you use Conditional Access. If someone turned them off and never built the policies, your tenant may have no MFA enforcement at all. The self-check below covers it. While you're in Entra, it's also worth looking for leftover guest accounts.
What does Premium add for laptops and phones?
Business Standard includes Basic Mobility and Security, a free, limited subset of Intune. It can enforce PINs and encryption on phones and wipe enrolled devices. On Standard it's mostly a phone story.
Premium includes Intune Plan 1, which adds the things people usually mean by "device management":
- App protection for staff-owned phones: protect work email and files (for example, block copy-paste into personal apps, or wipe only the work data) without enrolling the person's phone
- BitLocker enforcement and key recovery for Windows laptops, plus remote wipe
- macOS management
- Windows Autopilot, so new PCs can go straight to remote staff
If a laptop with client personal information goes missing, the OAIC lists a lost or stolen device holding customers' personal information as an example of a data breach under the Notifiable Data Breaches scheme. Enforced encryption and remote wipe don't change your obligations if the Privacy Act applies to your business. They do make "could anyone get to the data?" a much easier question to answer. Not legal advice.
What does Premium add for ransomware and email threats?
Defender for Business is endpoint security built for businesses of up to 300 employees. It provides next-generation protection, attack surface reduction, endpoint detection and response, and automated investigation and remediation. Standard isn't licensed for it. Servers need a separate add-on.
For email, both plans get Exchange Online Protection. Since Microsoft's 2026 packaging update, Standard also gets URL time-of-click protection. Premium has the full Defender for Office 365 Plan 1.
What does Premium add for client data?
Premium includes Purview DLP for Exchange, SharePoint and OneDrive (for example, stopping tax file numbers or card numbers going out by email). It also includes manual sensitivity labels such as "Confidential – client", Message Encryption, and org-wide retention policies.
What it doesn't include: automatic labelling, endpoint DLP and risk-based Conditional Access. Those need E5-level licensing, Entra ID P2 or a Purview add-on. Don't let anyone sell you Premium as if it does those.
Is it cheaper to add Defender or Entra ID P1 to Standard?
Usually not, unless you only need one piece. At the time of writing (October 2026, en-au, ex GST, annual): Standard AU$21.00 + Defender for Business AU$4.50 + Entra ID P1 AU$10.50 = AU$36.00. That's more than Premium at AU$32.90, and it still doesn't include Intune or the Purview features.
The exception: if laptops are your only worry, Defender for Business on its own at AU$4.50 is the cheapest single upgrade. Check current pricing.
Can you mix Standard and Premium licences?
Yes. Microsoft's own FAQ says not everyone in the organisation needs Premium. But there are two rules:
- Anyone a Premium policy protects or restricts needs a Premium licence (or the standalone equivalent). Conditional Access needs Entra ID P1 licences. Microsoft says an Intune licence is required for any user or device that benefits from Intune, and anyone benefiting from Purview information protection needs a licence. Putting Standard users inside a Premium-only policy is a licensing gap.
- The Business family caps out at 300 seats in total, across Basic, Standard and Premium combined.
A practical mixed pattern (my opinion, not a Microsoft rule): owners, finance, anyone handling client data and anyone on a personal phone get Premium. Casual or email-only staff stay on Standard and are kept out of Premium-only policies. Before you upgrade anyone, reclaim the seats nobody's using. There's no point paying the gap on an empty licence.
To move only some users, buy a Premium subscription and reassign their licences. The automatic plan change in the admin centre only works if everyone on that plan moves.
What does Premium mean for Essential Eight?
Premium gives you tools for several Essential Eight strategies. It doesn't give you a maturity level. That comes from configuring the tools, testing them and checking them over time.
| Essential Eight strategy | On Standard | What Premium adds |
|---|---|---|
| Multi-factor authentication | Security defaults | Conditional Access policies |
| Patch applications / operating systems | Updates on unmanaged PCs | Intune to push and report on updates |
| Application control | Nothing to manage it centrally | Intune can deploy Windows' built-in application control policies. You still have to build, test and maintain the allowed list |
| Restrict Microsoft Office macros / user application hardening | Manual, per device | Intune policies that users can't change, plus attack surface reduction rules (Defender for Business includes these) |
| Restrict administrative privileges | Role hygiene (free) | Conditional Access for admin accounts. Just-in-time admin access through Privileged Identity Management needs Entra ID P2 or ID Governance, which aren't in Premium |
| Regular backups | Not provided | Not provided |
At Maturity Level One, ASD expects things like macros disabled for users without a demonstrated business requirement, application control on workstations, and dedicated accounts for privileged users. Premium makes those easier to enforce and prove. It doesn't do them for you. And neither plan is a backup.
Is Business Premium worth it for a small business?
It's worth it when one or more of these is true:
- Staff read work email or files on personal phones
- A lost laptop would hold client personal information
- You hold client data and want rules on what can leave by email or file share
- You need sign-in rules such as "only our devices" or "MFA off-site"
- You're working towards Essential Eight, or a client or insurer questionnaire asks about MFA, patching, app control and admin access
- New PCs ship straight to remote staff
- Mailboxes are big and you have to keep email for years
Who should stay on Business Standard?
- Very small teams (say one to five people) on company-owned PCs set up by hand, with no client personal information beyond basic contacts, as long as security defaults are on
- Businesses already running a third-party device-management and endpoint-security stack (often through an MSP) that only need the apps
- Seasonal or email-only staff in a mixed tenant, kept out of Premium-only policies
If you stay on Standard and laptops are the worry, add Defender for Business before anything else.
Which plan do you need? A 10-minute self-check
Menu paths below match Microsoft Learn as of writing. Labels move, so verify on the day.
| Minutes | Where | What to look for |
|---|---|---|
| 0–2 | Microsoft 365 admin center → Billing → Your products | Which subscriptions you have (Standard, Premium, add-ons) and how many seats |
| 2–3 | Microsoft 365 admin center → Billing → Licenses | Assigned vs available. Unassigned seats are money before they're security |
| 3–4 | Microsoft 365 admin center → Users → Active users → select a user → Licenses and apps | Who's actually on Premium |
| 4–6 | Microsoft Entra admin center → Entra ID → Overview → Properties → Manage security defaults | On or off? If off, go to the next step |
| 6–7 | Microsoft Entra admin center → Entra ID → Conditional Access → Policies | Any policies? Security defaults off and no policies = no MFA enforcement |
| 7–8 | Microsoft Intune admin center → Devices → All devices | Are your PCs and phones enrolled? (On Standard, check Basic Mobility and Security instead) |
| 8–9 | Microsoft Defender portal → Assets → Devices | Are your laptops onboarded to Defender? |
| 9–10 | Microsoft Defender portal → Secure Score | A quick baseline across identity, devices and email |
Tag what you find: MFA gap · unmanaged laptops · personal phones with work email · client data without rules · unused seats. If most of your tags are the first four, Premium is probably worth the gap. If it's mostly the last, start by cleaning up licences.
When I do a Security Health Check for an Australian SMB, "which plan are you on, and is it actually switched on?" is one of the first questions I ask. Plenty of businesses are paying for Premium with half of it unconfigured. Plenty more are on Standard with security defaults switched off. If you want a second pair of eyes on which plan fits, and what to switch on first, without the big-firm theatre, see how I help with Microsoft 365 and security, or book a free chat.
