Here is the decision in one paragraph. Microsoft 365 Business Standard and Business Premium include the same Word, Excel, PowerPoint, Outlook and Teams, the same business email and the same 1 TB of OneDrive storage per user. What Premium adds is security and device control: Defender for Business, Defender for Office 365, Intune, Entra ID P1 with Conditional Access, and Purview data protection. At the time of writing (September 2026), Microsoft's pricing pages list Business Standard at $14.00 per user per month and Business Premium at $22.00 per user per month, both paid yearly. If your business handles client data, lets anyone work from a laptop or phone outside the office, answers to a compliance rule, or has to satisfy a cyber insurance application, Premium is almost always the right plan. Standard is the budget pick only for a very small, low-risk operation that plans to buy its security tools another way.
| At a glance (September 2026) | Business Standard | Business Premium |
|---|---|---|
| Desktop Office apps, email, Teams, 1 TB OneDrive | Included | Included, identical |
| List price, paid yearly (Microsoft pricing pages) | $14.00 per user per month | $22.00 per user per month |
| List price, monthly subscription | $16.80 per user per month | $26.40 per user per month |
| Defender for Business (endpoint detection and response, vulnerability management) | Not included | Included |
| Defender for Office 365 (phishing, malicious links and attachments) | Not included | Included |
| Intune Plan 1 (manage, protect and remotely wipe laptops and phones) | Not included | Included |
| Entra ID P1 (Conditional Access, risk-based sign-in rules) | Not included; standard MFA only | Included |
| Purview Data Loss Prevention and Information Protection | Not included | Included |
| Windows Hello for Business (biometric sign-in) | Not included | Included |
| Bundled with Copilot (paid yearly) | $23.50 per user per month | $32.00 per user per month |
| Seat limit | 300 users | 300 users |
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.
Still deciding between Microsoft and Google in the first place? That is a different comparison: Microsoft 365 vs Google Workspace. This article assumes you have chosen Microsoft and are picking the plan.
Microsoft 365 Business Premium vs Standard: what is the difference?
Business Standard gives you the desktop Office apps, business email through Exchange, Teams, SharePoint and 1 TB of OneDrive storage per user. Business Premium includes all of that and adds a security and management stack that is otherwise sold separately: Microsoft Defender for Business for endpoint protection, Defender for Office 365 for email threats, Intune for device management, Entra ID P1 for Conditional Access, and Purview for data loss prevention and information labeling. Same productivity, very different security posture.
What does Business Premium include that Standard does not?
Seven things, all named on Microsoft's own Business Premium page:
- Microsoft Defender for Business. Endpoint detection and response with vulnerability management, so a device that starts behaving like ransomware is isolated rather than scanned and ignored. Microsoft sells this standalone as a $3.00 per user per month add-on; Premium includes it.
- Microsoft Defender for Office 365. Protection against phishing, malicious links and weaponized attachments before they reach the inbox.
- Intune Plan 1. Enroll, configure and protect laptops and phones, require a compliant device before it can open company data, and wipe a device that walks out the door.
- Entra ID P1. Conditional Access: block sign-ins from unexpected countries, require stronger verification when a login looks risky, and stop legacy protocols that bypass MFA.
- Purview Data Loss Prevention. Policies that catch a spreadsheet of client Social Security numbers before it leaves through email or Teams.
- Purview Information Protection. Sensitivity labels that classify and encrypt documents, and that also decide what Copilot is allowed to surface later.
- Windows Hello for Business. Biometric and PIN sign-in tied to the device instead of a reusable password.
Together they turn a productivity subscription into a defended one.
How much more does Business Premium cost than Standard?
At the time of writing, Microsoft's pricing pages for Business Standard and Business Premium list $14.00 and $22.00 per user per month paid yearly, or $16.80 and $26.40 on a monthly subscription. Call the gap $8 per user per month on an annual plan. For a 15-person business that is $1,440 a year to move every employee onto managed, defended devices. Check Microsoft's pages for the figure on the day you buy, because the "with Copilot" bundles ($23.50 for Standard, $32.00 for Premium, paid yearly) now sit beside the base plans and change the sticker price.
Compare that gap 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. If a Copilot add-on shows up on your quote, that is a separate decision; we work through whether Microsoft Copilot is worth it in its own article.
Is Business Premium worth it for a small business?
For most businesses with more than a handful of people, yes. The clearest signals that Premium is the right plan:
- Anyone works from a laptop or phone outside the office, which means company data is on hardware you cannot see.
- You handle client records, financial data, health information or anything a regulator, an auditor or a client questionnaire cares about.
- Your cyber insurance application asks about MFA, endpoint detection and response, or device management. Premium supplies all three.
- Someone in the business can approve a wire or change a vendor's bank details. That is the person business email compromise targets, and Conditional Access plus Defender for Office 365 are the controls that blunt it.
- You are planning a Copilot rollout. Sensitivity labels and Conditional Access are how you keep Copilot from surfacing the wrong document to the wrong person.
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 Data Breach Investigations 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 one 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. Our guide to Conditional Access for small business walks through the policies worth turning on first.
Who should stay on Business 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.
Business Basic vs Standard vs Premium: where Basic fits
Business Basic, listed at $7.00 per user per month paid yearly, gives you email, Teams, OneDrive and the web and mobile versions of the Office apps, but not the installed desktop apps. It suits front-line or part-time staff who live in a browser. Standard adds the desktop apps. Premium adds the security stack on top of Standard. Many businesses run all three: Basic for staff who only need email and Teams, Standard for people who need desktop Excel but do not touch sensitive data, and Premium for everyone who does.
Can you mix Business Standard and Business Premium licenses?
Yes. Microsoft lets you assign different plans to different users, so you can put Premium on staff who handle sensitive data, approve payments or travel, and keep lighter users on Standard or Basic. One caution: the security value of Premium is partly tenant-wide. Conditional Access policies and Defender for Office 365 protect the accounts that are licensed for them, so leaving the office manager on Standard while the owner is on Premium leaves the person who processes invoices with the weaker protection. Decide the split by risk, not by seniority.
How to move from Business Standard to Business Premium
The license change itself takes minutes in the Microsoft 365 admin center. The work is what comes after, because the license is not the control:
- Onboard every device to Defender for Business and confirm each one reports in.
- Enroll laptops and phones in Intune with a compliance policy, then require a compliant device to reach email and files.
- Turn on Conditional Access: MFA for everyone, block legacy authentication, restrict sign-ins by location where that fits.
- Configure Defender for Office 365 Safe Links and Safe Attachments and review the anti-phishing policy.
- Create the first Purview DLP policy for the data you most need to keep in (payment card numbers, health records, client identifiers) and the first sensitivity labels.
- Confirm backup. Microsoft's retention is not a backup; see the shared responsibility model.
Our Microsoft 365 management service does this configuration and keeps it current, and our managed IT services include licensing reviews so you are not overpaying for seats you do not need or under-protecting the ones you do.
Business Premium, cyber insurance and compliance
Insurance applications increasingly ask the same three questions: is MFA enforced everywhere, is there endpoint detection and response on every device, and are devices managed. Business Premium answers all three with Entra ID P1, Defender for Business and Intune, which is why we point most renewals at it first; our note on cyber insurance requirements covers the rest of the list. For HIPAA and similar rules, Premium provides many of the expected technical controls, and Microsoft will sign a business associate agreement, but configuration is what makes an environment compliant. The license is a strong foundation, not an automatic checkmark.
Frequently asked questions
Is Microsoft 365 Business Premium worth the extra cost?
If anyone in the business works outside the office, handles sensitive data, or can move money, yes. The $8 per user per month gap on an annual plan buys endpoint detection and response, device management, Conditional Access and data loss prevention, which cost more bought separately and are harder to run as separate products.
What is the difference between Business Standard and Business Premium?
The apps, email and storage are identical. Premium adds Defender for Business, Defender for Office 365, Intune, Entra ID P1 and Purview data protection. Standard has none of those. It is a security and management difference, not a productivity difference.
Does Business Premium include Copilot?
No. Microsoft 365 Copilot is a separate purchase. At the time of writing, Microsoft lists the Copilot Business add-on at $18.00 per user per month paid yearly, or Business Premium bundled with Copilot at $32.00 per user per month paid yearly. Microsoft 365 Copilot Chat, the web-grounded assistant, is included at no additional cost for Entra users with an eligible subscription.
Does Business Premium replace our antivirus?
For most small businesses, yes. Defender for Business is a full endpoint protection platform with detection and response, not just antivirus. Some firms layer a managed detection service on top for round-the-clock monitoring, but you generally do not need a separate antivirus product.
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 at 2 a.m. Higher-risk or compliance-bound businesses often add managed detection and response so someone acts on a threat when it happens rather than the next morning.
Is Business Premium enough for HIPAA or other compliance?
It provides many of the technical controls frameworks expect, including encryption, access control and data loss prevention, and Microsoft will sign a business associate agreement. Compliance depends on configuration, policies and evidence, not the license alone.
What is the 300-user limit?
All Business plans, including Premium, cap at 300 licensed users per tenant. Businesses growing past that move to the Enterprise plans, where the closest security equivalent is Microsoft 365 E5 or E3 with add-ons.
Can we switch from Standard to Premium in the middle of a term?
Yes. Upgrading mid-term is routine; Microsoft prorates the change, and the higher plan takes effect immediately. Moving down is restricted until the term ends, which is one reason to buy Premium only for the users who need it and run a mix.
