Microsoft 365 Business Standard vs. Business Premium: What’s the Difference?

If your business is choosing between Microsoft 365 Business Standard and Business Premium, you’re weighing more than a price difference. Both plans include the same Office apps, Teams, email and file storage. The real difference is security: how well your accounts, devices and data are protected.

Here’s a side-by-side comparison, followed by what each difference means in practice.

Bottom line: Business Standard provides Microsoft’s core productivity and collaboration tools. Business Premium adds a much stronger security, identity and device-management layer.

Plan contents and pricing change periodically. Check Microsoft’s current plan details, or ask TCI, before you buy.

What Business Standard Includes

Business Standard is Microsoft’s core productivity plan for small and midsize businesses (both Business plans support up to 300 users). It includes the desktop, web and mobile versions of Word, Excel, PowerPoint and Outlook; business email through Exchange; Microsoft Teams for chat, meetings and calling; and OneDrive and SharePoint for file storage and collaboration.

It also includes basic security features, such as multi-factor authentication through Microsoft’s security defaults, plus built-in spam and malware filtering for email. For a small team with simple needs and other security tools already in place, that may be enough.

What Business Premium Adds

Business Premium includes everything in Business Standard, plus a security layer that many businesses would otherwise buy separately:

Microsoft Defender for Business

Endpoint protection for Windows, Mac, iOS and Android devices, including endpoint detection and response (EDR) that watches for suspicious behavior, not just known viruses. Learn how managed EDR works.

Defender for Office 365 Plan 1

Stronger email protection, including Safe Links (checking links when they’re clicked) and Safe Attachments (opening attachments in a safe environment first), plus extra protection against phishing and impersonation. See our email security approach.

Microsoft Intune

Device management for company and personal devices: enforce security settings, deploy apps, require encryption and remotely wipe a lost laptop or phone. Learn about Intune.

Microsoft Entra ID P1 and Conditional Access

Smarter sign-in rules. Conditional Access can block sign-ins from unexpected countries, require MFA only when risk is higher, or allow access only from managed devices. It’s one of the most effective defenses against stolen passwords. Learn about Entra ID.

Information Protection

Sensitivity labels and data loss prevention (DLP) help keep confidential information, like client financial data or Social Security numbers, from being shared where it shouldn’t be.

Which Plan Is Right for Your Business?

Business Standard can make sense when: your team is small, you already have separate endpoint and email security you’re happy with, you don’t store much sensitive client data, and you don’t face compliance or cyber insurance requirements around device management.

Business Premium usually makes sense when: you handle sensitive client or financial information; you’re in a regulated or higher-risk industry (accounting, legal, healthcare, financial services, government); employees work remotely or on personal devices; your cyber insurance questionnaire asks about MFA, EDR and device management; or you want to consolidate several separate security tools into one Microsoft plan.

For many businesses, the cost difference between the two plans is less than the cost of buying comparable security tools separately. But licenses only help if they’re configured. Business Premium’s protections need to be set up and managed to deliver real value.

Microsoft 365 Business Standard vs. Business Premium FAQ

What is the difference between Microsoft 365 Business Standard and Business Premium?

The main difference is security and device management. Business Standard provides the core productivity tools businesses need, including Outlook, Word, Excel, PowerPoint, Teams, OneDrive and SharePoint.

Business Premium includes those productivity tools and adds advanced security and management capabilities such as Microsoft Defender for Business, Microsoft Intune, Microsoft Entra ID P1, Conditional Access and Defender for Office 365 Plan 1.

In simple terms: Business Standard = productivity and collaboration. Business Premium = productivity + security + device management.

Is Microsoft 365 Business Premium worth it?

For many small and midsize businesses, yes, particularly if you need stronger cybersecurity, centralized device management or more control over how employees access company information.

The important comparison isn’t just the difference in Microsoft licensing cost. Consider whether Business Standard would require you to buy separate endpoint security, email security, identity protection or device management products.

Does Microsoft 365 Business Premium include Microsoft Intune?

Yes. Business Premium includes Microsoft Intune Plan 1 for centralized management of supported computers and mobile devices. Intune helps enforce security policies, manage applications, evaluate device compliance and protect company information on managed devices. Learn about Intune.

Does Microsoft 365 Business Premium include Microsoft Defender?

Yes. Business Premium includes Microsoft Defender for Business for endpoint security and Microsoft Defender for Office 365 Plan 1 for additional email and collaboration protection, important capabilities for organizations concerned about ransomware, phishing, malware and compromised devices.

Does Microsoft 365 Business Standard include Defender?

Business Standard includes Microsoft’s baseline security protections, but not Microsoft Defender for Business or Defender for Office 365 Plan 1 the way Business Premium does. If you use Business Standard, evaluate what endpoint and email security is protecting your users and devices. See our email security approach.

Does Business Premium include Conditional Access?

Yes. Business Premium includes Microsoft Entra ID P1, which provides Conditional Access. You can create policies that decide when and how users access Microsoft 365, based on identity, device compliance, application and sign-in conditions. That’s significantly more control than passwords and MFA alone. Learn about Entra ID.

Is MFA included with Microsoft 365 Business Standard?

Yes, multi-factor authentication can be used with Business Standard. However, Business Premium’s Entra ID P1 and Conditional Access give you more sophisticated control over when MFA is required and when access should be allowed or blocked.

Is Microsoft 365 Business Premium better for cybersecurity?

Generally, yes, if the included security capabilities are properly configured and managed. Business Premium adds tools for endpoint protection, identity security, email protection, information protection and device management.

But purchasing Business Premium doesn’t automatically secure an organization. Conditional Access, Intune and Defender still need to be configured, monitored and maintained.

Can Microsoft 365 Business Premium replace third-party cybersecurity products?

It can replace some products, but not necessarily your entire security stack. Business Premium can reduce the number of separate tools needed for endpoint security, identity protection, device management and email security.

Some organizations still benefit from additional services such as managed EDR, email security, SIEM and 24/7 monitoring, security awareness training and backup. The better approach is to evaluate your entire security stack rather than automatically choosing Microsoft or third-party tools for everything.

Is Microsoft 365 Business Premium good for small businesses?

Yes. Business Premium is designed for small and midsize organizations and is especially attractive for businesses that want productivity, security and device management under a more consolidated licensing model. It’s particularly useful for companies with remote or hybrid employees, sensitive information, cyber insurance requirements, managed laptops and mobile devices, or growing compliance requirements.

Should remote employees use Microsoft 365 Business Premium?

Business Premium is often a strong fit for remote and hybrid teams, because Intune and Conditional Access give you more control over the devices and circumstances under which people access company information. You can build policies around managed devices, security compliance and authentication instead of relying on a password alone.

Do I need Business Premium for cyber insurance?

Not necessarily. Requirements vary by carrier, policy and organization. However, insurers increasingly ask about MFA, endpoint protection, email security, identity security, patching and device management.

Business Premium provides several technologies that help implement those controls, but simply buying the license doesn’t demonstrate they’ve been configured. See how TCI helps with cyber insurance questionnaires.

Does Microsoft 365 Business Premium include Microsoft Copilot?

Microsoft 365 Copilot should be evaluated separately from the core Business Premium security decision. Microsoft offers licensing and packaging options that combine Microsoft 365 and Copilot, and these offerings change over time.

Before deploying Copilot broadly, review your SharePoint permissions, OneDrive sharing, Teams access, identity security and data governance. Learn about Copilot consulting.

Do all employees need Microsoft 365 Business Premium?

Not necessarily. Some organizations combine licenses based on roles and security requirements. However, mixed licensing needs careful planning: security and management policies may depend on features licensed to individual users, so choosing Standard for some employees solely to save money can create complexity or security gaps.

TCI recommends designing your Microsoft 365 licensing around users, devices, data access and security requirements, not just picking the lowest-cost license for each employee.

Can I upgrade from Microsoft 365 Business Standard to Business Premium?

Yes. You can move users from Business Standard to Business Premium as your security and management needs grow. Before upgrading, plan how you’ll actually implement the Premium capabilities, particularly Intune, Defender for Business and Conditional Access.

Which is better: Microsoft 365 Business Standard or Business Premium?

There isn’t one answer for every organization. Choose Business Standard when your main need is Microsoft productivity and collaboration and you already have appropriate security and device management. Consider Business Premium when you also want Microsoft’s advanced identity, endpoint, email security and device management capabilities.

For many small and midsize businesses, Business Premium provides the stronger overall security foundation.

Still Not Sure Which Microsoft 365 Plan Is Right for Your Business?

TCI Technologies can review your existing Microsoft 365 licenses, users, devices, security tools, MFA, Conditional Access, Intune, Defender, SharePoint permissions and Copilot plans to determine which licensing model makes the most sense.

Rather than simply recommending the more expensive license, we’ll help determine where Business Standard, Business Premium, or a combination of licensing and third-party security tools is the best fit. Serving businesses across Long Island, New York City and the Tri-State area.
