What you get, how it compares, and whether the upgrade is worth it for your business.
Microsoft 365 Business Premium is the top-tier licence in Microsoft’s SME product line. It bundles the full productivity suite with enterprise-grade security, device management, and data protection in a single per-user subscription. For organisations that need both productivity tools and a serious security posture, it is the most cost-effective way to get both from one platform.
But Premium is not the right choice for every organisation. It costs roughly twice as much as Standard and nearly four times as much as Basic. The additional spend only makes sense if you actually need the security and management capabilities it includes. For some businesses, Standard or Basic with targeted add-ons is a better fit. For others, Premium is the obvious choice and trying to replicate its capabilities through individual purchases would cost significantly more.
This guide breaks down exactly what Business Premium includes, how it compares to the other licence tiers, which security features matter most, and how to determine whether the upgrade makes sense for your organisation. No sales pitch. Just a clear, practical assessment of what you are paying for and whether you need it.

What Business Premium includes
Premium is not just Standard with a higher price tag. It adds an entirely separate layer of capabilities focused on security, compliance, and device management. These are the four pillars of what you get beyond the standard productivity tools.
Productivity apps
Business Premium includes the full desktop suite: Word, Excel, PowerPoint, Outlook, OneNote, and Access. These are not the web-only versions you get with Basic. They are the full, locally installed applications with offline capability, advanced features, and regular feature updates. Each user also gets 1TB of OneDrive storage, a 50GB Exchange Online mailbox, and full access to SharePoint and Teams. For most knowledge workers, this is the standard toolkit. The difference is that Premium bundles it with everything else on this list, rather than requiring separate purchases.
Security features
This is where Premium earns its name. You get Microsoft Defender for Business, which provides enterprise-grade endpoint protection across Windows, macOS, iOS, and Android. You get Azure AD Premium P1, which unlocks Conditional Access policies so you can control who accesses what, from where, on which devices. You get Safe Links and Safe Attachments, which scan URLs and email attachments in real time before they reach your users. These are not optional extras. For any organisation handling sensitive data or operating in a regulated sector, they are foundational controls.
Device management
Microsoft Intune is included with Premium, giving you full mobile device management and mobile application management. You can enforce security policies on every device that accesses company data, whether it is a company-owned laptop or a personal phone. Windows Autopilot lets you configure and deploy new devices without ever touching them physically. Remote wipe capability means a lost or stolen device can be secured in minutes, not days. For organisations with remote or hybrid workers, this is not a nice-to-have. It is the mechanism that makes secure remote working possible at scale.
Data protection
Azure Information Protection lets you classify and label documents based on sensitivity, then apply encryption and access controls that travel with the file regardless of where it goes. Data Loss Prevention policies can prevent sensitive information from being shared outside the organisation, whether by email, Teams, or file sharing. Sensitivity labels integrate across the entire Microsoft 365 suite, so your finance team can mark a spreadsheet as confidential and know that the protection applies whether it is opened in Excel, viewed in SharePoint, or shared via Teams.
“The question is not whether Premium costs more than Standard. It does. The question is whether buying the security features separately would cost even more. For most organisations, the answer is yes, by a significant margin.”


How it compares to Basic and Standard
Microsoft offers three Business licence tiers. The productivity features scale predictably across them. The real divergence is in security, device management, and data protection, where Premium stands alone. Understanding the differences helps you avoid both overspending and underprotecting.
Business Basic
Basic is the entry-level plan. You get web and mobile versions of Office apps, but no desktop applications. Email, Teams, SharePoint, and OneDrive are all included, and each user gets 1TB of cloud storage. Security is limited to the baseline protections built into Microsoft 365: standard spam filtering, basic malware detection, and multi-factor authentication. There is no endpoint protection, no Conditional Access, no device management, and no advanced threat protection. For very small teams with straightforward needs and minimal security requirements, Basic covers the essentials. But if you are handling client data, operating under any compliance framework, or supporting remote workers, the gaps become apparent quickly.
Business Standard
Standard adds the full desktop Office suite, which is the most visible upgrade over Basic. You also get additional tools like Bookings, Forms, and Planner. However, the security and device management capabilities are identical to Basic. There is no Defender for Business, no Conditional Access, no Intune, and no Azure Information Protection. Standard is the right choice if your primary need is productivity software and your security requirements are being met by other tools. Many organisations start here and later discover they need the Premium security features, at which point they face either upgrading or purchasing add-ons that often cost more than the Premium licence would have.
Business Premium
Premium includes everything in Standard, plus the full security, device management, and data protection stack described above. The price difference between Standard and Premium is roughly eight to nine pounds per user per month. For that, you get endpoint protection, Conditional Access, Intune, Safe Links, Safe Attachments, Azure Information Protection, and Data Loss Prevention. Purchased individually as add-ons, these capabilities would cost significantly more. Premium is not the cheapest option, but it is the most complete. For organisations that need both productivity and security from a single platform, it represents the best value per pound spent.

Security features in depth
The security capabilities in Premium are the primary reason to upgrade. Each of these features addresses a specific category of risk that Basic and Standard leave entirely unprotected. Together, they form a security baseline that aligns with frameworks like Cyber Essentials and provides genuine protection against the threats that target SMEs most frequently.
Defender for Business
Defender for Business is Microsoft's endpoint protection platform, included with Premium at no additional cost. It provides next-generation antivirus, endpoint detection and response (EDR), automated investigation and remediation, and vulnerability management. It covers Windows, macOS, iOS, and Android from a single console. This is not the basic Windows Defender that ships with the operating system. It is the enterprise-tier product, with threat intelligence drawn from Microsoft's global sensor network processing over 65 trillion signals per day. For most SMEs, it eliminates the need for a separate endpoint protection purchase entirely.
Conditional Access
Conditional Access is the policy engine that controls how and when users can access your organisation's resources. You can create rules based on user identity, device state, location, application, and risk level. For example: require MFA when accessing email from outside the UK. Block access from devices that are not enrolled in Intune. Require a compliant device to access SharePoint. These policies run automatically and enforce your security posture without relying on user behaviour. For organisations pursuing Cyber Essentials or any compliance framework, Conditional Access is the tool that turns security policies into enforceable technical controls.
Intune device management
Intune gives you centralised management of every device that touches company data. You can push configuration profiles, enforce encryption, require screen locks, mandate OS updates, and control which applications are allowed to access corporate resources. For company-owned devices, you get full management. For personal devices under a BYOD policy, you can apply application-level controls without managing the entire device, protecting company data without invading personal privacy. The Windows Autopilot integration means new devices can be shipped directly to employees, who sign in once and receive their full configuration, policies, and applications automatically.
Safe Links and Safe Attachments
Safe Links rewrites URLs in emails and Office documents, routing them through Microsoft's scanning infrastructure at the moment of click. If a link was safe when the email arrived but was later weaponised, Safe Links catches it when the user actually clicks. Safe Attachments opens email attachments in a sandboxed environment before delivery, detonating any malicious payloads before they reach the user's inbox. Together, these two features address the most common attack vectors: phishing links and malicious attachments. They operate transparently, requiring no user action or training, which makes them particularly effective for organisations where security awareness varies across the team.
Who should choose Premium
Premium is the right licence for organisations where security is not optional. If you handle sensitive client data, operate in a regulated industry, need to meet compliance standards like Cyber Essentials, or support a workforce that includes remote or hybrid employees, the capabilities in Premium are not luxuries. They are the baseline controls you need to operate responsibly.
Professional services firms, legal practices, accountancies, healthcare providers, financial services companies, and any organisation that processes personal data under GDPR should be seriously considering Premium. The same applies to businesses that work with larger organisations or public sector clients, where demonstrating a mature security posture is increasingly a prerequisite for winning and retaining contracts.
If you currently run Standard and supplement it with a separate endpoint protection tool, a separate device management platform, or separate email security, add up what those tools cost. In most cases, upgrading to Premium consolidates everything into one licence at a lower total cost, with the added benefit of tighter integration between the components.
When Standard is enough
Not every organisation needs Premium. If your team is small, your data sensitivity is low, and your industry has no specific compliance requirements, Standard gives you the full productivity suite at a significantly lower cost. You still get the desktop Office apps, Teams, SharePoint, OneDrive, and Exchange. For day-to-day productivity, Standard and Premium are identical.
Standard also makes sense as a starting point for growing businesses that are not yet ready to implement the full security and management stack. You can upgrade individual users or your entire tenant to Premium later without disruption. Some organisations take a mixed approach, licensing sensitive roles like finance, HR, and leadership on Premium while keeping other users on Standard. Microsoft supports this, though it adds licensing complexity that needs managing.
The critical thing is to make the decision consciously. Too many organisations end up on Standard by default, because it was what their IT provider quoted or because nobody assessed the security requirements. If you have evaluated the risks, understand what Premium includes, and determined that Standard meets your needs, that is a valid decision. If you are on Standard simply because nobody asked the question, it is worth revisiting.
“The organisations that get the most value from Premium are not the ones with the biggest budgets. They are the ones that understand what they are protecting and have made a deliberate decision about how to protect it.”
