Microsoft 365 Business Standard vs Business Premium: Which Plan Does Your Business Actually Need?
The difference between Microsoft 365 Business Standard and Business Premium isn't really about features. It's about what level of security control your business actually needs. This article cuts through the Microsoft marketing and gives you a decision framework based on the controls that matter, not the feature list.
The price difference is real. The capability difference is bigger.
Business Standard runs around $18–19 per user per month. Business Premium runs around $25–26 per user per month. That's roughly an $8 difference per user. For a 20-person business, that's around $1,900 per year more for Premium.
The question is what that $1,900 buys. The answer is: the security controls that determine whether your Microsoft 365 environment is actually defensible or just functional.

The two controls that matter most
Of everything Premium adds, Conditional Access and Microsoft Intune are the controls that change the actual security posture of your environment.
Conditional Access lets you define rules around who can access what, from where, on what device, under what conditions. MFA alone says: prove you are who you say you are. Conditional Access says: even if you can prove that, you still cannot access corporate data from a non-compliant device, or from an unusual location, or outside business hours. It is the difference between a single lock on your front door and a system that checks context before unlocking anything.
Intune lets you manage the devices your staff use. That means you can enforce encryption, require screen locks, remotely wipe a lost device, push security policies, and ensure that unmanaged personal devices do not get unrestricted access to corporate data. If any of your staff work remotely or use personal devices, Intune is the relevant control.
When Business Standard is genuinely enough
- You have very few users (under 5) with limited data sensitivity
- All work happens on company-owned, desktop-only machines that never leave the office
- You handle no sensitive client, financial, or personal data
- There are no compliance, insurance, or regulatory requirements around data security
- You have no plans to deploy Copilot in the near term
In practice, that describes very few Australian businesses with growth ambitions. The moment you have remote workers, personal devices accessing email, client data, or any kind of compliance obligation, Standard's security controls are materially insufficient.
When Business Premium is the right call
- 01
Staff work remotely or use personal devices
Without Intune, you cannot enforce policies on those devices. Without Conditional Access, you cannot prevent unmanaged devices from accessing corporate data. Both come with Premium.
- 02
You handle sensitive client or financial data
Professional services firms, accountants, financial advisers, legal practices, healthcare providers: your data sensitivity warrants the additional controls Premium provides.
- 03
You are subject to cyber insurance requirements
Insurers increasingly ask specifically about MFA, Conditional Access, device management and Defender. Business Premium provides the tools to meet those requirements. Standard does not.
- 04
You are planning to deploy Microsoft Copilot
Copilot queries all the data a user has access to. You need governance, permissions and sensitivity labelling in place before deploying it. Most of those controls require Premium.
- 05
You want Microsoft Defender protecting email
Defender for Office 365 Plan 1 (included in Premium) adds Safe Links and Safe Attachments to your email flow, providing meaningful protection against phishing links and malicious attachments. Standard does not include this.
Most Australian businesses with 10 or more employees handling any form of client or financial data should be on Business Premium. The additional cost per user is typically less than one hour of incident response work if something goes wrong on an inadequately secured environment.
The question you should actually be asking
The Standard vs Premium decision is really a proxy for a more important question: what security posture does your business actually need, and do your current licences give you the tools to implement it?
Many businesses are on Premium and not using any of the additional controls. Others are on Standard and wondering why their security advisor keeps telling them they have gaps. The licence is not the problem in either case — configuration and implementation are.
Before upgrading licences, it is worth knowing what you are actually running. A structured assessment of your current environment tells you what controls are in place, what is missing, and whether your licence tier even covers the gaps you have.
