Microsoft 365 Business Standard and Business Premium look almost identical from a user's point of view. Both include the desktop Office apps, Exchange email, Teams, SharePoint and OneDrive, and both are designed for businesses with up to 300 users. The difference is everything users don't see: security, device management and data protection.
What Business Standard includes
- Desktop, web and mobile versions of Word, Excel, PowerPoint and Outlook
- Exchange Online business email with a 50 GB mailbox
- Teams for chat, meetings and calling add-ons
- SharePoint and OneDrive with 1 TB of storage per user
- Basic security: Exchange Online Protection spam and malware filtering, and security defaults for MFA
What Business Premium adds
- Microsoft Intune: manage and secure Windows, Mac, iOS and Android devices. Push apps, enforce encryption, and wipe a lost laptop.
- Windows Autopilot: ship a new laptop straight to an employee and have it configure itself when they sign in.
- Microsoft Entra ID P1: Conditional Access, so you can require MFA based on risk, block sign-ins from unmanaged devices or other countries, and control guest access.
- Microsoft Defender for Business: endpoint detection and response (EDR) for your devices, the control most cyber insurers now ask about.
- Defender for Office 365 Plan 1: Safe Links and Safe Attachments that check links and files at the moment they're opened, plus anti-impersonation protection.
- Microsoft Purview Information Protection: sensitivity labels, data loss prevention and message encryption for confidential information.
- Exchange Online Archiving: expanded archive storage and retention for mailboxes.
Who needs Business Premium?
If your business handles client financial data, health information, legal matters or anything covered by a contract or insurance policy, Business Premium is usually the right default. Buying Intune, Defender and Entra ID P1 separately costs more than the upgrade, and running without them leaves the exact gaps that insurers and auditors ask about.
Business Standard can make sense for very small teams with no regulated data, or for specific users in a mixed environment.
You can mix plans
Licenses are assigned per user, so you don't have to put everyone on the same plan. A common setup is Business Premium for office staff who handle sensitive data, and Business Basic or a frontline plan for users who only need email and Teams on the web. Be careful, though: security policies such as Conditional Access only protect users who are licensed for them.
Check current pricing
Microsoft adjusts pricing and packaging regularly, including how Teams is bundled in some regions. Check current prices with Microsoft or your licensing partner before you budget, and review whether annual or monthly commitment terms suit you better.
The bottom line
Business Standard is a productivity suite. Business Premium is a productivity suite plus the security and management platform a modern business needs. If you're on Standard and paying for separate antivirus, device management or email filtering, a license review may show that Premium costs less overall.
