Microsoft 365 Business Premium
The difference over Standard is security and device management, and it arrives switched off.
Business Premium costs more than Standard almost entirely because of its security and device management capability. That capability arrives at defaults, so a business that upgrades and changes nothing has paid more for exactly what it had before.
What to enable, in order
Multi-factor authentication first, for administrators and then everyone. A password alone protects nothing once it has been reused on a site that was later breached, and business email is the common target because it is the route to invoice fraud.
Conditional access next, introduced in report-only mode. That shows what a policy would have blocked without blocking it, which surfaces the legitimate case you did not think of before it locks someone out mid-morning.
Multi-factor authentication
Administrators first, then everyone, with the awkward cases handled individually rather than left as permanent exemptions.
Conditional access
Who may sign in, from where and on what device — starting in report-only mode so nothing breaks unannounced.
Device management
Passcode, encryption, and the ability to wipe company data from a lost device without touching personal photographs.
Anti-phishing
Impersonation protection for the people most likely to be spoofed, external sender marking, and link checking at click time.
What it does not include
Backup. Microsoft protects the service and offers retention settings; that is not the same as a backup you control and can restore from after a deletion discovered three months later.
And configuration. The features that make Business Premium worth its price require turning on and setting up, which is the whole reason this page exists.
Microsoft 365 Business Premium — Frequently Asked Questions
What does Business Premium add over Business Standard?+
Almost entirely security and device management rather than productivity features — conditional access, device policy, advanced anti-phishing and identity protection. It is worth the difference if you will configure and use them.
What should we enable first?+
Multi-factor authentication, for administrators and then everyone. It addresses the most common route into a business mailbox, and every other control assumes accounts are not trivially accessible.
Will device management let us see personal data on staff phones?+
Company data can be managed and removed independently of personal content. The distinction is worth explaining to staff before enabling it, since it is the first question people ask.
Does it stop phishing emails?+
It reduces them substantially through impersonation protection, external sender marking and link checking. It does not eliminate them, which is why a process for confirming bank-detail changes by phone remains necessary.
Can we mix Premium and Standard across the team?+
Yes, and most businesses should. Note that security capability applies per licence, so it protects the users who hold it — assigning Premium to five of thirty protects five.
How does this relate to the DPDP Act?+
Retention and access controls support obligations around keeping personal data no longer than necessary and limiting who can see it. The tooling helps; the policy decisions remain the organisation's.
