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. 1.

[What does this mean for Easi’s Microsoft customers?](https://blog.easi.net/en/the-new-microsoft-365-business-premium-add-ons-explained#for-easi-customers) 5. [Final thoughts](https://blog.easi.net/en/the-new-microsoft-365-business-premium-add-ons-explained#final-thoughts) --- ## **Why new add-ons for Business Premium?** 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. | Read more: [Microsoft 365 in 2026: New capabilities, Copilot SKUs and pricing](https://blog.easi.net/en/microsoft-365-in-2026-new-capabilities-copilot-skus-and-pricing?hsLang=en) In our dedicated analysis, we explain what Microsoft 365 licensing will look like in 2026, how Copilot fits into this landscape, and what these changes mean for organisations planning their IT roadmap. | | --- | ## **The three new Microsoft 365 Business Premium add-ons** ### **1) Microsoft Defender for Business Server Add-on** 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. ### **2) Microsoft Defender for Business Identity Add-on** 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. ### **3) Microsoft 365 Business Compliance Add-on** 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. ## **Which add-on fits your organisation?** At Easi, we help customers navigate licensing choices every day. The right choice depends on three elements: ### **1. Your environment** - 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** ### **2. Your security maturity** - Basic → stick with Business Premium only - Growing → Identity and/or Server Add-ons - Advanced → pair Business Premium with the Identity and Compliance Add-ons ### **3. Your risk profile** - Handling financial, HR, or customer data - Working with subcontractors - Multiple sites - Users working remotely These factors make the add-ons much more relevant. ## **What does this mean for Easi’s Microsoft customers?** 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,  --- ## **Final thoughts** 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](https://easi.net/en/services/microsoft#paragraph-1876) determine which combination fits your environment, your risks, and your long-term IT strategy.
