Microsoft 365 Business Premium Gets Stronger: Renamed Suites and New Security & Compliance Add-Ons for SMBs

Microsoft Security and Compliance Options for SMBs

Small and midsized businesses rely on Microsoft 365 Business Premium as a reliable foundation for productivity and collaboration. With Office apps, Teams, advanced security and device management included, it gives growing businesses an all-in-one platform at a predictable cost.

But cyber threats continue to evolve, and compliance requirements are becoming more demanding. Phishing, identity theft, insider risks and regulatory pressure put added strain on lean IT teams. To help address these challenges, Microsoft has introduced three new add-ons for Business Premium. These bring enterprise-grade security and compliance features to SMBs at a price point designed for smaller organizations.

These new add-ons are designed specifically for organizations with up to 300 users. Let’s look at what’s new, how each suite strengthens protection and why the combined option delivers significant savings.

Note: On October 1, 2025, Microsoft renamed its Microsoft 365 E5 mini-suites. Microsoft 365 E5 Security is now the Microsoft Defender Suite, and Microsoft 365 E5 Compliance is now the Microsoft Purview Suite. The functionality and included features remain the same—only the names have changed.

Unfortunately, the bad guys are equal opportunity attackers—they don’t just go after organizations with enterprise budgets. The Defender Suite brings top-tier identity, device, email and cloud app security into one package.

Key benefits for SMBs:

  • Identity protection that stops attacks in real time with Microsoft Entra ID P2’s risk-based conditional access and governance.
  • Device security at the enterprise level through Microsoft Defender for Endpoint Plan 2, including endpoint detection and response (EDR).
  • Phishing defense + attack simulations with Microsoft Defender for Office 365 P2, helping train your employees while automatically responding to threats.
  • Cloud app protection + shadow IT visibility with Microsoft Defender for Cloud Apps, giving IT leaders control over risky SaaS usage.

Purview Suite for Business Premium ($10/user/month)

Purview focuses on data protection and compliance, bringing the same tools used by large enterprises, simplified and cost-reduced for SMBs.

Key benefits for SMBs:

  • Insider risk detection that uses analytics to flag unusual behavior before it becomes a breach.
  • Data protection that follows the file with sensitivity labels, encryption and data loss prevention (DLP).
  • Compliant communications that flag risky or inappropriate content across email, Teams and even third-party apps.
  • AI safety controls that monitor how AI tools like Copilot interact with sensitive data.
  • Investigation readiness with eDiscovery and deep audit logs. No more scrambling when regulators or legal teams ask for data.

Purview helps you prove compliance, avoid fines and build customer trust. All while saving your IT team time.

Defender + Purview Suite ($15/user/month)

Want it all? The combined suite gives you every capability in Defender and Purview for just $15/user/month.

  • Enterprise-grade protection across identity, endpoints, email and apps
  • Advanced compliance, risk management and AI data governance
  • A simplified, single add-on that saves you money

The math: Buying these features separately as standalone products would cost $47.20/user/month. With the combined SMB suite, you pay $15. That’s a 68% savings.

Enterprise Versions of the Suites

On the enterprise side, Microsoft offers the same products under the Microsoft Defender Suite and Microsoft Purview Suite, each priced at $144 per user per year. These are the renamed versions of the former Microsoft 365 E5 Security and Microsoft 365 E5 Compliance add-ons.

Microsoft Defender Suite includes:

  • Defender for Endpoint Plan 2 ($62.40)
  • Defender for Office 365 Plan 2 ($60)
  • Defender for Identity Plan 2 ($66)
  • Defender for Cloud Apps ($42)
  • Entra ID P2 ($108)

Buying this bundle saves about $194.40 per user per year compared to buying each product individually.

Microsoft Purview Suite includes:

  • eDiscovery & Audit ($78)
  • Insider Risk Management ($78)
  • Information Protection and Governance ($84)

Buying this bundle saves about $96 per user per year versus purchasing each component separately.

While functionality remains the same, these enterprise suites are ideal for customers who need more than 300 seats or already have an enterprise base license.
