New Security & Compliance Add-ons for Microsoft 365 Business Premium

Microsoft has just introduced three new add-ons for Microsoft 365 Business Premium, designed to help businesses strengthen their security and compliance posture without the enterprise price tag. 

These add-ons are built to help organisations improve their security, fulfill compliance requirements, and manage risk, all while continuing to operate within the familiar Microsoft 365 environment. 

1. Microsoft Defender Suite for Business Premium Add-On – $10US/user/month 

This suite provides end-to-end protection against identity threats, device risks, email phishing, and risky cloud apps. Previously, these tools were only available for large enterprises. It includes: 

• Microsoft Entra ID P2: Advanced identity protection and governance with real-time risk-based conditional access. 

• Microsoft Defender for Identity: Deep visibility into identity infrastructure with posture recommendations and threat detection. 

2. Microsoft Purview Suite for Business Premium Add-On – $10US/user/month 

This suite focus on helping organisations meet compliance and data protection requirements. It includes: 

• Data Loss Prevention (DLP) across Microsoft 365 apps. 

• Information Protection for classifying and encrypting sensitive data. 

• Audit and eDiscovery tools for regulatory and legal readiness. 

3. Microsoft Entra Suite for Business Premium Add-On – $10US/user/month 

This suite streamlines identity governance and access management. It includes: 

• Automated onboarding and access workflows. 

• Lifecycle management for user identities. 

• Enhanced reporting and alerts for suspicious activity. 

Why These Add-Ons Matter 

• Enterprise-Level Security for SMBs: These solutions help bridge the gap between small and large businesses by offering advanced threat detection, identity protection, and endpoint security without requiring a full-time security team. 

• Streamlined Compliance Management: With increasing regulatory demands, tools like Microsoft Purview simplify data governance, retention, and privacy oversight, which is especially beneficial for industries such as healthcare, finance, and legal. 

• Enhanced Visibility and Rapid Response: Microsoft Defender provides real-time threat monitoring and incident response, helping reduce dwell time and minimise the impact of security breaches. 

• Seamless Integration with Microsoft 365: Because these tools are built into the Microsoft ecosystem, businesses can enjoy a unified experience without managing multiple security platforms and vendors.  

Key Details  

• Availability: Launching September 2025 

• Licensing: Each of the above Add-Ons require a minimum of 25 users, and supports up to 300 users per tenant
