Business Standard gives you desktop and web versions of Office apps, email and cloud storage; Business Premium adds device management, advanced threat protection and identity security controls — the difference matters most for businesses handling sensitive data or wanting stronger cyber security.
Choosing between Microsoft 365 licences is one of the most common questions we get, and it's easy to default to the cheaper option without realising what's missing. This guide breaks down the practical differences so you can make an informed choice rather than guessing.
What's in Business Standard
Business Standard is aimed at core productivity. It typically includes:
- Desktop versions of Word, Excel, PowerPoint and Outlook
- Exchange Online for business email
- 1TB of OneDrive storage per user
- SharePoint and Teams
- Basic email security features
What Business Premium adds
Business Premium includes everything in Standard, plus a set of security and device management features aimed specifically at SMEs that need stronger protection without paying for full enterprise-grade licensing. Key additions include:
- Microsoft Intune — mobile device and PC management, letting you enforce security policies (like requiring encryption or a PIN) on company and even personal devices accessing company data
- Microsoft Entra ID P1 (formerly Azure AD Premium P1) — conditional access policies, meaning you can restrict sign-ins based on location, device compliance or risk level
- Microsoft Defender for Business — more advanced endpoint protection than the basic antivirus included in Standard, with detection and response capabilities. See our related guide on whether Microsoft Defender is enough for a small business for more on this specifically
- Windows 365 / Autopilot compatibility for easier device provisioning in some setups
- Additional data loss prevention and information protection features

Who Business Standard suits
- Very small businesses with low regulatory or data sensitivity requirements
- Businesses that already have separate, robust endpoint security and device management tools in place
- Organisations with tight budgets and low risk exposure — though this should be a deliberate decision, not a default
Who Business Premium suits
- Any business handling client personal data, financial information or sensitive intellectual property
- Businesses with staff working on personal devices, or a mix of company and personal device access to email and files
- Organisations pursuing Cyber Essentials or Cyber Essentials Plus, where device compliance and access control requirements map closely to what Premium enables — see our guide on what Cyber Essentials actually requires
- Businesses that want to enforce multi-factor authentication and conditional access consistently, rather than relying on individual staff to opt in
A worked example
Picture a fictional 20-person recruitment agency handling candidate CVs, client contracts and financial details, with staff who regularly check email on personal phones and occasionally work from cafés or client sites. On Business Standard, there's no way to enforce that a lost phone is remotely wiped, or that email access is blocked from a device in an unexpected location. On Business Premium, both of those controls are available out of the box through Intune and conditional access. Given the sensitivity of the data involved, the cost difference is, in our experience, one of the easier security investments to justify.
Common mistakes
- Choosing Standard purely on price without assessing data sensitivity. The features in Premium map directly onto common cyber security requirements — cutting them to save a modest monthly amount per user can be a false economy.
- Assuming Premium alone means you're "covered" on security. Licensing gives you the tools; someone still needs to configure and monitor conditional access policies, device compliance rules and Defender alerts for it to be effective.
- Mixing licences without a clear reason. Some businesses assign different licences to different staff based on role, which can work well, but should be a deliberate decision tied to data access, not an accident of who was set up first.
- Forgetting that neither licence includes a full backup solution. See our guide on whether Microsoft 365 backs up your data — this is a separate consideration regardless of which licence you choose.
Recommendations
In our experience, most SMEs handling any client data, financial records or personal information are better served by Business Premium, because the incremental cost is generally modest relative to the security capability gained, particularly around device management and conditional access. Businesses with very simple, low-risk operations may reasonably start on Standard, but should revisit that decision as they grow, take on more staff, or handle more sensitive data. Either way, licensing is only the starting point — configuration and ongoing monitoring matter just as much as which licence you buy.
