Microsoft 365 Buyer’s Guide: Which Microsoft 365 Plan Does Your Business Need?

Choosing a Microsoft 365 plan can look simple until you start comparing productivity applications, email, cybersecurity, device management, identity protection, data security and AI.

The least expensive plan isn’t always the least expensive solution.

A business may save money on Microsoft 365 licensing but then need separate products for endpoint security, email protection or device management. Another business may already have excellent third-party security and little reason to duplicate those capabilities.

This Microsoft 365 Buyer’s Guide will help you determine what your organization actually needs before choosing a plan.

Start With What Your Business Actually Needs

Before comparing licenses, answer six questions:

1. How many users do you have?
2. Which Microsoft applications do employees need?
3. Where do employees work?
4. How will you secure their identities and devices?
5. What cybersecurity products do you already have?
6. Are you planning to use Microsoft Copilot or other AI tools?

Your answers can quickly narrow down the right Microsoft 365 licensing strategy.

1. How Many Microsoft 365 Users Do You Have?

Microsoft’s Business plans are designed for organizations with up to 300 users. For most small and midsize businesses, common options include Microsoft 365 Business Basic, Business Standard and Business Premium. Organizations approaching or exceeding 300 users should generally begin evaluating Microsoft enterprise licensing as part of their strategy.

But don’t choose licenses based only on employee count. A 25-person financial firm handling sensitive customer information can have very different security requirements than a 100-person organization where most employees work from a controlled office environment.

2. Which Microsoft 365 Applications Do Your Employees Need?

Start with the basics. Do employees need Outlook, Word, Excel, PowerPoint, Microsoft Teams, OneDrive, SharePoint, the desktop Microsoft 365 applications, and business email?

Microsoft’s business plans provide different combinations of these capabilities. For businesses that need the full desktop productivity suite along with business email, Teams, OneDrive and SharePoint, Business Standard is often the logical starting point. Microsoft currently lists desktop, web and mobile versions of its primary apps as part of both Business Standard and Business Premium.

But productivity requirements are only half the decision. The next question is increasingly important: how are you going to secure everything?

3. Where Do Your Employees Work?

The modern workplace has changed the Microsoft 365 licensing conversation. Your employees may work in the office, from home, from multiple locations, while traveling, and from company laptops, personal computers, smartphones and tablets.

Ask yourself: do we just need employees to access Microsoft 365, or do we also need to control the devices accessing our information? That distinction matters.

When Device Management Becomes Important

If you’re issuing company laptops or allowing remote access to company information, consider whether you need centralized device management. Microsoft 365 Business Premium includes device management and security capabilities designed to protect company devices, including Microsoft Intune.

Device management lets you set standards for security configurations, device compliance, encryption, application deployment, corporate data and access policies. For a workforce operating from multiple locations, that can be a significant advantage.

4. What Are Your Cybersecurity Requirements?

This is where the difference between Microsoft 365 plans becomes much more significant. Ask:

Identity: Do we require MFA? Do we need Conditional Access? Do we want policies controlling how users sign in? Do we need stronger protection against compromised accounts?

Devices: Do we need endpoint security? Do we manage employee laptops? Do we need device compliance policies? Do remote devices need centralized management?

Email: How are we protecting users against phishing? What happens when someone receives a malicious attachment? Are links in email being evaluated for threats?

Data: Do we handle financial information, personal information, healthcare information, employee records or customer confidential information?

These questions often determine whether Business Standard or Business Premium makes more sense.

5. Business Standard vs. Business Premium

Here’s the easiest way to think about the two plans.

Microsoft 365 Business Standard

Best suited for businesses primarily looking for productivity and collaboration: Outlook, Word, Excel, PowerPoint, Teams, Exchange business email, OneDrive and SharePoint. Business Standard can be an excellent option when your cybersecurity and device management requirements are already addressed through other platforms.

Microsoft 365 Business Premium

Best suited for businesses that want productivity plus Microsoft’s additional security and device management capabilities. Beyond the productivity foundation, Microsoft highlights capabilities around identity and access, device security and management, email and threat protection, and sensitive-data protection, including Microsoft Entra ID, Microsoft Intune, Microsoft Defender and Microsoft Purview.

The simplest distinction: Business Standard = Productivity. Business Premium = Productivity + Security + Device Management.

6. Do You Already Have Cybersecurity Products?

This is one of the most important questions, and one of the most commonly overlooked. Don’t purchase Business Premium simply because it contains more features. First determine what you’re already paying for. Your business may already have:

• Endpoint detection and response (EDR)
• Managed detection and response (MDR)
• Email security
• DNS and web filtering
• Identity protection
• Security awareness training
• Microsoft 365 backup
• SIEM and 24/7 monitoring

If these are already part of your managed cybersecurity environment, compare them against the capabilities included in Business Premium. You could discover unnecessary overlap, or an opportunity for consolidation.

Compare the Total Technology Stack

Instead of evaluating Business Standard vs. Business Premium, evaluate Business Standard + your existing cybersecurity products versus Business Premium + the security products you still need. That’s a much more useful comparison.

7. Does Business Premium Replace Your Cybersecurity Stack?

Not necessarily. Microsoft describes Business Premium as including device security, threat protection and protection for sensitive data. But having security technology included in a license doesn’t automatically mean an organization is secure. Someone still needs to answer:

• Are security policies configured correctly?
• Is MFA enforced appropriately?
• Is Conditional Access properly designed?
• Are devices enrolled and managed?
• Are security alerts being monitored?
• Who investigates suspicious activity?
• Who responds to an incident?
• Is Microsoft 365 data backed up?
• Is somebody monitoring security after normal business hours?

Licensing is not the same thing as security management. That distinction is particularly important when evaluating Business Premium.

8. Are You Planning to Use Microsoft Copilot?

AI should now be part of the Microsoft 365 licensing conversation.

Confirm the Copilot packaging. Microsoft offers different Copilot experiences depending on your Microsoft 365 plan and licensing. Before purchasing, confirm which Copilot capabilities are included and which require an additional license. Review Microsoft’s current Copilot licensing options.

But don’t make Copilot solely a licensing decision. Before expanding it across your organization, review the information users can already access through SharePoint, OneDrive, Teams, Microsoft 365 Groups and shared repositories. Also evaluate identity security, device security, external sharing, data classification, information governance and AI policies.

AI can make information dramatically easier to find. That makes getting your permissions and information governance right even more important. See our Microsoft 365 Copilot consulting and AI advisory services.

9. What About Cyber Insurance?

Cyber insurance questionnaires increasingly focus on the controls an organization has implemented, not simply the products it owns. You may see questions about MFA, endpoint protection, email security, device management, privileged access, backups, security monitoring and incident response.

Business Premium can provide Microsoft technologies that support several of these controls. But owning a security capability and implementing it are two different things. Don’t answer a cyber insurance questionnaire based solely on the Microsoft licenses you own; verify how the controls are actually configured. See how TCI helps with cyber insurance readiness.

10. Should Every Employee Have the Same Microsoft 365 License?

Not always. Some organizations can appropriately combine licenses based on job responsibilities, device usage, information access, remote work, security and application requirements.

However, mixed licensing should be intentional. Saving a few dollars per license can become a poor trade-off if it complicates your security policies or prevents you from consistently managing users and devices. Start with the employee’s requirements, not the price of the license.

Which Microsoft 365 Plan Should You Choose?

Consider Business Standard if: your primary requirement is Microsoft productivity and collaboration, and your organization already has appropriate cybersecurity, identity and device management solutions.

Consider Business Premium if: you want to combine Microsoft productivity with additional security, identity and device management in the Microsoft ecosystem.

Consider a mixed licensing strategy if: your employees have substantially different jobs, devices and access requirements, and you can maintain consistent security without creating unnecessary management complexity.

Consider a Microsoft 365 Licensing Review if: you’re already paying for multiple Microsoft licenses and third-party cybersecurity products and aren’t sure where they overlap. That’s often where the biggest opportunities exist.

Don’t Buy Microsoft 365 Based on Price Alone

The objective isn’t to find the cheapest Microsoft 365 license. It’s to find the most appropriate combination of productivity, security, device management and support for your business.

For some organizations, that’s Business Standard paired with a well-designed third-party cybersecurity stack. For others, Business Premium can provide a strong foundation for consolidating identity, endpoint and device management. And increasingly, businesses also need to consider how their licensing strategy supports AI, Microsoft Copilot and data governance.
