Product Overview and Comparison
Microsoft 365 Enterprise plans — E3, E5, and E7 — are designed for larger organizations that require advanced productivity, security, compliance, and AI capabilities at scale, with no limit on the number of users. Each plan builds on the one before it. Below is an overview of what each plan includes and the value it delivers.

Why It Matters for Your Business
Microsoft 365 E3 brings together productivity, device management, identity protection, and data security in a single suite — removing the need to license and manage these capabilities separately. It gives organizations a consistent, secure experience across every device and location, supports compliance requirements through built-in data governance tools, and provides the scalability that growing enterprises need beyond the 300-user cap of the Business plans.
Microsoft 365 E5
Designed for: Organizations with advanced security, compliance, or analytics requirements.
What's Included
- Everything in Microsoft 365 E3, plus:
- Advanced threat protection across identity, endpoints, and cloud applications
- Advanced compliance tools, including insider risk management and premium eDiscovery
- Microsoft Teams Phone System for cloud-based calling
- Power BI Pro for advanced business intelligence and data visualization
- Audio conferencing for meetings
- Expanded identity protection and access governance
Why It Matters for Your Business
Microsoft 365 E5 is built for organizations operating in higher-risk or highly regulated environments — such as finance, healthcare, or government — where deeper visibility into threats, insider risk, and data handling is essential. It consolidates capabilities that would otherwise require multiple standalone security and analytics tools into a single license, giving security and compliance teams stronger oversight while giving business leaders richer insight into organizational data through integrated analytics.
Microsoft 365 E7 — Frontier Suite
Designed for: Organizations ready to embed AI, and AI agents, securely across their operations.
What's Included
- Everything in Microsoft 365 E5, plus:
- Microsoft 365 Copilot — AI integrated directly into Word, Excel, PowerPoint, Outlook, Teams, and other everyday tools
- Microsoft Entra Suite — expanded identity and secure network access controls, including Zero Trust capabilities
- Microsoft Agent 365 — a centralized governance and security layer for AI agents operating across the organization, integrated with existing security and compliance tools
Why It Matters for Your Business
Microsoft 365 E7 is designed for organizations moving beyond individual AI assistance toward AI agents that actively perform work across departments and workflows. It brings Copilot, advanced identity protection, and agent governance together under one license and one management layer, so IT and security teams can extend the same policies and protections they already trust to every AI agent operating in the environment. For organizations already investing in Copilot and Zero Trust security, E7 consolidates that investment into a single, unified suite.
Summary
- Microsoft 365 E3 — a complete productivity, device management, and security foundation for organizations of any size.
- Microsoft 365 E5 — the full E3 experience plus advanced security, compliance, and business analytics for higher-risk environments.
- Microsoft 365 E7 (Frontier Suite) — the full E5 experience plus Microsoft 365 Copilot, expanded identity protection, and governance for AI agents.
All Enterprise plans are built on the same Microsoft 365 platform, supporting unlimited users and a smooth transition between plans as organizational needs evolve.
