E1 and E3 plans both include MyAnalytics, a personal productivity insight tool that allows a user to view their work patterns, network, collaboration, and more.

E5 also offers Power BI Pro, a powerful analytical data visualization tool to view specific insights about your business.

All things Security

E1 is limited in terms of security and offers anti-malware, Active Directory Sync, mail filtering, and more privacy and security features offered in most Microsoft 365 packages.

E3 includes Azure Information Protection, which includes important tools that allow one to classify important data and only give access to people who need to view it. It also comes with eDiscovery and Defender. Where E3 shines is with its Azure AD Multi-Factor Authentication, where it’s used across all users to ensure that all cybersecurity threats are prevented.

E5 offers the most advanced security protection from cyber attacks. It includes Advanced Threat Protection, which scans any link on any team’s chat or office applications. It also includes Customer Lockbox to ensure Microsoft can’t access your content without approval and Microsoft Defender for Cloud Apps for cyberthreat security.
