For many small and medium-sized businesses, Microsoft 365 Business Premium is the foundation of their digital workplace. It combines productivity apps with advanced security features like Defender for Business and device management at a cost-effective price.
But Microsoft is now taking this one step further by introducing three new add-ons designed specifically for Business Premium customers. These add-ons bring enterprise-grade security, compliance, and identity protection into the SMB ecosystem, without requiring an enterprise licence.
Below, we break down what’s new, why it matters, and how to decide which add-ons fit your organisation.
Microsoft’s reasoning is simple: SMBs now face enterprise-level threats, but often lack enterprise-level tools.
Business Premium already includes a strong baseline (Office apps, Teams, Defender for Business, MDM, etc.), but until now, some advanced controls were only available in the E5 suite.
With the new add-ons, Microsoft closes that gap — giving mid-sized companies access to:
Stronger identity protection
Advanced compliance
Deeper threat detection
Better data governance
More granular security controls
All of this without forcing organisations into a full E5 licence.
These new add-ons also reflect a broader evolution in Microsoft 365 licensing. Microsoft is increasingly moving away from one-size-fits-all licence bundles towards more modular, role-based and security-focused options — including new Copilot SKUs and updated pricing models.

This add-on extends Defender for Business protections to:
Windows Server 2016
Windows Server 2019
Windows Server 2022
You get:
Next-gen AV
Endpoint Detection and Response (EDR)
Real-time threat detection
Automated investigation and response
Ideal for organisations in a hybrid situation: this add-on ensures your server workloads are protected with the same high-level security as your endpoints.
Identity is the number-one attack vector. Microsoft knows it, and so do we!
This add-on brings Defender for Identity capabilities to Business Premium, enabling:
Identity threat detection (lateral movement, brute force, credential theft, etc.)
Advanced monitoring of on-prem Active Directory
Alerts for suspicious authentication behaviour
Integration with Microsoft’s XDR ecosystem
Ideal for organisations with hybrid AD setups: this is a powerful upgrade that significantly improves visibility into identity-based attacks.
For growing organisations, compliance is no longer optional.
This add-on introduces key enterprise-level compliance features, such as:
Information Protection
Data Lifecycle Management
Communication Compliance
Audit improvements
Insider Risk Management (light edition)
This add-on fills a major gap is ideal if you handle sensitive data, work in a regulated industry, or simply want more control over how information is used and stored.
At Easi, we help customers navigate licensing choices every day. The right choice depends on three elements:
Hybrid with on-prem servers → Server Add-on
If On-prem AD is still part of your identity → Identity Add-on
Sensitive data, contracts, or regulation → Compliance Add-on
Basic → stick with Business Premium only
Growing → Identity and/or Server Add-ons
Advanced → pair Business Premium with the Identity and Compliance Add-ons
Handling financial, HR, or customer data
Working with subcontractors
Multiple sites
Users working remotely
These factors make the add-ons much more relevant.
Well, these add-ons mean a lot, in a positive way.
For our customers that already run on Business Premium, these add-ons allow them to:
Strengthen their security without jumping to E5
Fill key gaps in identity protection and compliance
Build a more robust foundation for NIS2, ISO27001 or SOC initiatives
Reduce risk in hybrid or transitional environments
Continue evolving their security at a predictable cost
In general, this is a welcome evolution for small and medium-sized businesses that want stronger cybersecurity without unnecessary complexity,
Microsoft is clearly shifting towards a future where SMBs receive the same powerful protections as enterprise environments, but packaged in a way that is accessible and cost-effective.
For organisations running Microsoft 365 Business Premium, these add-ons offer a smart way to strengthen your IT security posture, improve compliance, and prepare for future regulations.
At Easi, we’re ready to help you determine which combination fits your environment, your risks, and your long-term IT strategy.
