Microsoft has introduced a combined security and compliance add-on for Business Premium subscribers, delivering enterprise-grade protection and governance at a fraction of the traditional cost.
This bundle integrates advanced threat detection, identity protection, data governance, and regulatory compliance tools. Organizations can secure every user, device, and system while simplifying compliance with evolving standards like HIPAA, GDPR, and PCI. The suite is priced at $15 per user per month, representing a 68% savings compared to purchasing the components separately.
In this episode of the Demystifying Microsoft podcast, Wade Walker (VP, Microsoft Alliance at Sourcepass MCOE) explores the real-world impact of Microsoft’s new combined Defender and Purview Suite for Business Premium. The discussion covers how organizations can leverage this bundle to reduce risk from phishing, identity theft, and insider threats, protect sensitive data across platforms, and stay ahead of regulatory requirements, all while saving money and streamlining deployment.
The bundle brings together advanced threat protection (Defender for Endpoint, Defender for Office 365, Defender for Identity, Defender for Cloud Apps, Entra ID Plan 2) and robust compliance tools (eDiscovery, Audit, Insider Risk Management, Information Protection, DLP, Encryption, Data Security Posture Management). This unified approach enables organizations to protect every user, device, and system, while simplifying compliance and reducing operational complexity.
By integrating automated threat detection, real-time identity monitoring, and data governance, the bundle helps organizations defend against phishing, identity theft, insider threats, and risky cloud app usage. It also supports proactive compliance with regulatory standards, minimizing the risk of fines and breaches.
The bundle combines advanced security (Defender) and compliance (Purview) capabilities for Microsoft 365 Business Premium. It provides threat detection, identity protection, data governance, and regulatory compliance tools in a single, cost-effective package.
Organizations that need enterprise-grade security and compliance without the complexity or expense of E5 licensing. It’s ideal for businesses with up to 300 users looking to simplify protection and regulatory management.
It offers built-in tools for data loss prevention, insider risk management, audit logs, and eDiscovery. These features help organizations meet standards like HIPAA, PCI, and GDPR, and adapt to changing regulations.
Yes, licensing is flexible. You can assign the suites to specific users or groups, but Microsoft recommends deploying it broadly for comprehensive protection.
The suites includes monitoring and management tools to track AI usage, enforce ethical policies, and reduce risks associated with unauthorized or unapproved AI solutions.
As organizations face increasing pressure from evolving cyber threats and regulatory demands, the Defender & Purview combined suite for Business Premium offers a practical solution for strengthening security and simplifying compliance. By integrating advanced protection and governance tools at a competitive price, this bundle empowers teams to safeguard data, reduce risk, and stay ahead of industry standards. It eliminates the complexity of traditional enterprise licensing and makes robust security accessible.
