Here is the decision in one line: if your business handles any sensitive data, lets people work from laptops or phones, or has to answer to a compliance rule, Microsoft 365 Business Premium is almost always worth the extra money over Business Standard. The two plans include the same Office apps and email. What you pay more for in Premium is security and device control, not features your staff will notice day to day.
That distinction trips up a lot of owners. They compare the two plans, see the same Word, Excel, Outlook, and Teams on both, and assume Standard is the smart budget pick. The apps are identical. The protection around them is not.
What is the actual difference between Standard and Premium?
Business Standard gives you the desktop Office apps, business email, Teams, and 1 TB of OneDrive storage per user. Business Premium includes all of that and adds a security and management stack: Microsoft Defender for Business, Intune device management, Entra ID P1, and data-protection tools from Microsoft Purview. Same productivity, very different security posture.
What security does Premium add that Standard doesn't?
Premium adds four things Standard simply does not have: Microsoft Defender for Business for endpoint protection that stops ransomware and malware rather than just scanning for it, Intune to manage and remotely wipe company laptops and phones, Entra ID P1 for conditional access and risk-based multifactor authentication, and Purview data-loss-prevention controls. Together they turn a productivity subscription into a defended one.
How much more does Premium cost?
At current list pricing, Business Standard runs about $14 per user per month and Business Premium about $22, on an annual commitment either way. Check Microsoft's pricing page for the exact figure today, since Microsoft now bundles Copilot options that change the sticker price. Call the gap roughly $8 per user per month. For a 15-person business that is about $1,440 a year to move every employee onto managed, defended devices.
Compare that to buying the pieces separately. A standalone endpoint protection product, a mobile device management tool, and an identity add-on usually cost more combined than the $8 Premium bump, and they do not talk to each other as cleanly.
Why the identity features matter more than they sound
Stolen credentials were behind about a third of breaches at small and midsize businesses in Verizon's 2025 report. Entra ID P1, which only comes with Premium, is what lets you enforce conditional access, block logins from unexpected locations, and require stronger verification when something looks off. That single capability closes one of the most common ways attackers get in. It also pairs well with managed detection and response if you layer that on top.
Who should stay on Standard?
Standard can be the right call for a very small, low-risk operation: no regulated data, no remote work, no employees who can move money, and a plan to add security tools another way. Even then, most businesses that start on Standard end up wishing they had the device management the first time a laptop goes missing. If you handle client records, payment data, or anything covered by HIPAA or similar rules, Premium is the floor, not the upgrade.

Frequently asked questions
Can I mix Standard and Premium licenses in one company?
Yes. Microsoft lets you assign different plans to different users, so you can put Premium on staff who handle sensitive data or travel and keep lighter users on Standard. Many businesses run a mix to balance cost and protection.
Does Business Premium replace our antivirus?
For most small businesses, yes. Defender for Business, included in Premium, is a full endpoint protection platform, not just antivirus. Some firms still layer on a managed detection service for round-the-clock monitoring, but you generally do not need a separate antivirus product on top.
Do we still need a separate MDR service with Premium?
It depends on who watches the alerts. Premium gives you the tools; it does not give you a human reviewing them around the clock. Higher-risk or compliance-bound businesses often add managed detection and response so someone acts on a threat at 2 a.m., not at 9 a.m.
Is Business Premium enough for HIPAA or compliance?
Premium provides many of the technical controls compliance frameworks expect, like encryption, access control, and data-loss prevention, and Microsoft will sign a business associate agreement. Configuration is what makes it compliant, though. The license is a strong foundation, not an automatic checkmark.
