Microsoft 365 offers a range of licensing options designed to meet the diverse needs of businesses. Two of the most popular enterprise plans are Microsoft 365 E3 and Microsoft 365 E5. While both plans provide robust productivity and collaboration tools, they differ significantly when it comes to security features. This blog explores the key security features in Microsoft 365 E5 and compares them with E3, helping you understand which plan best suits your organization’s security requirements.
Before diving into the security features, it’s essential to understand the core differences between the Microsoft 365 E5 and E3 plans. Both plans include popular Office applications like Word, Excel, and Outlook, along with services like Teams, SharePoint, and OneDrive. However, Microsoft 365 E5 offers advanced security, analytics, and voice capabilities that go beyond what’s available in E3.
The E3 plan provides a solid foundation for productivity and collaboration while including essential security and compliance features. It covers basic data protection, device management, and compliance tools suitable for most businesses.
The E5 plan builds upon the E3 offering by adding advanced security, analytics, and voice capabilities. It’s designed for organizations that require comprehensive security measures, sophisticated compliance tools, and enhanced data insights.
Microsoft 365 E3 includes several essential security features that help protect your organization’s data and users.
E3 offers Data Loss Prevention policies that help prevent the unintentional sharing of sensitive information. Organizations can set up rules to detect and restrict the sharing of confidential data like credit card numbers or social security numbers.
This plan includes basic threat protection for emails, attachments, and links. It helps defend against phishing attacks and malware, providing a layer of security for communication channels.
E3 comes with Azure Active Directory Premium P1, which offers essential identity and access management features like multi-factor authentication (MFA), conditional access, and self-service password reset.
E3 includes Microsoft Information Protection, enabling users to classify, label, and protect documents and emails. This helps ensure that sensitive data remains secure, even when shared outside the organization.
The E3 plan includes compliance tools such as eDiscovery, legal hold, and data governance. These features help organizations meet regulatory requirements and manage data effectively.
Microsoft 365 E5 enhances the security capabilities available in E3, offering more comprehensive protection against advanced threats.
Microsoft 365 E5 includes Defender for Office 365 Plan 2, which adds advanced threat protection features like automated investigation and response (AIR), threat trackers, and attack simulation training. These tools help organizations detect, investigate, and respond to sophisticated threats more effectively.
This feature provides advanced endpoint protection, detecting and responding to threats across devices. It includes behavioral analytics, endpoint detection and response (EDR), and threat intelligence integration.
Defender for Identity uses on-premises Active Directory signals to identify, detect, and investigate advanced threats, compromised identities, and malicious insider actions within your network.
Microsoft 365 E5 includes Cloud App Security, a Cloud Access Security Broker (CASB) that provides visibility into cloud app usage, detects unusual behavior, and enforces policies to prevent data leaks.
Microsoft 365 E5 upgrades identity and access management with Azure AD Premium P2. This version includes all the features of P1 plus advanced identity protection, Privileged Identity Management (PIM), and risk-based conditional access policies.
Understanding the differences between Microsoft 365 E5 and E3 security features can help organizations choose the right plan based on their needs.

Deciding between Microsoft 365 E5 and E3 depends on your organization’s specific security needs, budget, and regulatory requirements.
E3 is suitable for organizations that need robust productivity tools with essential security and compliance features. It’s ideal for businesses that handle less sensitive data and have standard security requirements.
Microsoft 365 E5 is designed for organizations that require comprehensive security and compliance solutions. It’s particularly beneficial for industries with strict regulatory requirements, such as finance and healthcare, or for businesses that face advanced cyber threats.
While Microsoft 365 E5 offers the most comprehensive security features, it also comes at a higher cost. Organizations should assess the potential risks and costs associated with data breaches or compliance failures when deciding whether the additional investment in Microsoft 365 E5 is justified.
Microsoft 365 E5 and E3 both offer robust security features, but Microsoft 365 E5 provides a more comprehensive suite of tools designed to protect against advanced threats and meet complex compliance needs. Understanding the key differences between these plans helps organizations make informed decisions that balance security, compliance, and budget considerations. Whether you choose E3 or E5, Microsoft 365 offers powerful tools to safeguard your organization’s data and users.
