Most small and mid-sized organizations run on Microsoft 365 Business Standard or Business Basic. The common assumption is that if Microsoft hosts the email and files, it also protects them. That’s only partly true.
Basic licensing gives you tools to work with, not a full layer of protection. It has no Conditional Access, no device management, no advanced phishing protection and no endpoint protection. Preventing a breach means protecting all of these together, and above all the user accounts.
This article is for IT and security managers who need to present the move to Business Premium to management: what it includes, which gaps it closes, and how to give management two real options to decide between.
What Business Premium includes
Business Premium includes everything in Business Standard and adds a full security layer on top:
| Area | Component | What it gives you |
|---|---|---|
| Identity | Microsoft Entra ID P1 | Conditional Access, phishing-resistant MFA and single sign-on (SSO) to apps |
| Device management | Microsoft Intune | Manage computers and phones, compliance policies, encryption and remote wipe |
| Email protection | Defender for Office 365 Plan 1 | Advanced protection against phishing, malicious links and attachments |
| Data loss prevention | Microsoft Purview DLP | Blocks sensitive data from being sent outside the organization |
| Classification and encryption | Purview Information Protection | Sensitivity labels and encryption that stay with the file, even outside the organization |
| Endpoint protection | Defender for Business | Antivirus, EDR and automatic response to threats |
It costs $22 per user per month. In July 2026 Business Standard went up to $14, and Business Premium didn’t change. The gap between the two plans is now only $8 per user per month.
Four gaps you have to close
Management doesn’t care about product names. It cares about how to prevent a breach. These are the four gaps to show them, and Business Premium closes every one.
- Account takeover. Most breaches of Microsoft 365 start with a stolen username and password. Ordinary MFA with an SMS code or an app approval is no longer enough: attackers get around it with phishing sites that relay the sign-in as it happens. The answer is phishing-resistant MFA, such as a FIDO2 key, a passkey or Windows Hello for Business, which can’t be handed to a fake site. You enforce it with Conditional Access, which comes only with Business Premium.
- Phishing attacks. Email is the main way into an organization. Defender for Office 365 checks links when they are clicked, opens attachments in an isolated environment, and spots people impersonating managers and suppliers.
- Data leaks. An employee who sends a file with customer details by mistake, or who leaves with documents, is a real risk. DLP blocks sensitive data from being sent, and sensitivity labels encrypt the file so only authorized people can open it, even after it leaves the organization.
- Unmanaged devices. A computer that isn’t managed or protected is a way in for an attacker. Intune makes sure every computer is encrypted and up to date, and Defender for Business detects threats and isolates a compromised computer. Conditional Access can also block access to company data from a device that doesn’t meet the requirements.
Company data on phones. Most employees read email and open company files on their personal phone. What happens when the phone is stolen, or when an employee leaves? Without protection, the company’s email, files and contacts stay with them. Intune can protect company data inside the apps themselves (App Protection), even on a personal phone that isn’t fully enrolled:
- Company data in Outlook, Teams and OneDrive is stored encrypted and kept apart from personal data.
- Company data can’t be copied into personal apps such as WhatsApp or Gmail, or saved to the photo gallery.
- When a phone is stolen or an employee leaves, only the company data is wiped remotely. The employee’s personal photos and messages aren’t touched.
It also answers employees’ worry that the company will manage their personal phone: the company controls only its own data.
Consolidation: the tools you already pay for
Before you show management the cost of the upgrade, map the security tools the organization already pays for. In most cases part of the cost of Business Premium is offset by tools you can stop paying for. Check these:
- Endpoint antivirus or EDR, which Defender for Business can replace.
- Third-party email filtering, which Defender for Office 365 can replace.
- MFA or identity management from another vendor, which Entra ID can replace.
- Device management (MDM) for phones and computers, which Intune can replace.
- File encryption or DLP from another vendor, which Purview can replace.
For each tool, note the annual cost and the contract renewal date. The real saving comes from timing the switch to the renewal dates, so you never pay twice for the same capability.
Two options for management to choose from
Managers don’t like being handed a single option, because then there’s nothing to decide. So present two real options. Both close all four gaps:
| Option A: Business Premium | Option B: Business Standard plus separate tools | |
|---|---|---|
| Base licence | $22 per user per month | $14 per user per month |
| Identity and phishing-resistant MFA | Included | Extra product |
| Device management | Included | Extra product |
| Email protection | Included | Extra product |
| DLP and encryption | Included | Extra product |
| Endpoint protection | Included | Extra product |
| Vendors to manage | One | Up to five |
| Integration between tools | Built in | Depends on the vendors |
In option B, each of the five extra products usually costs a few dollars per user per month. Added together, the total usually exceeds the $8 gap. Fill in the table with real prices from quotes, not estimates.
You can also offer a variation of option A: Business Premium for only some users, for example management, finance and people who work outside the office. It lowers the cost of the move but leaves part of the organization less protected.
How to present it to management
- Start with the risk, not the technology. “What happens if someone gets into the CFO’s mailbox?” works better than a feature list.
- Show the four gaps and where the organization stands on each today.
- Show both options with real prices, including the tools you can stop paying for.
- Show the consolidation savings next to the cost. Management needs to see the net number, not just the increase.
- Recommend, but leave the decision to management. The goal is for management to choose, not to approve a decision already made for them.
In summary
Business Premium closes, in one package, the four gaps most organizations are breached through: account takeover, phishing, data leaks and unmanaged devices. Once you offset the tools you can stop paying for, it is almost always cheaper than five separate products.
