Office 365 GCC G5 without Power BI and Phone System

A lighter-weight cloud app discovery and control capability bundled into Office 365 E5 — a subset of the standalone Microsoft Defender for Cloud Apps.

A cloud access security broker (CASB): discovers shadow IT, and applies session/access policies across sanctioned SaaS apps. The Office 365-scoped tier only covers Microsoft 365 activity; the full product extends that policy control to third-party cloud apps.

Retention labels and policies that keep content an organization needs and delete content it doesn't, on a defined schedule.

Keep or delete content on a schedule, org-wide or by label, across Exchange, SharePoint, OneDrive, and Teams — for regulatory retention requirements or simply to reduce stale-data risk.

Manual sensitivity labeling for Office documents and email to classify and protect content.

Classify and protect content (encryption, watermarking, access restriction) by applying labels users pick or that get applied for them. Manual, user-applied labeling is the base tier; automatic labeling (content is scanned and labeled without user action) needs the higher tier.

Extends Microsoft Purview Audit with a longer retention window and additional high-value audit log events for forensic investigations.

A searchable log of user and admin activity across Microsoft 365. Standard covers 180 days of retention and core events; Premium extends retention to a year (with add-ons to 10 years), adds high-value crucial events (mailbox access, mail-forwarding-rule changes), and higher log bandwidth for faster forensic investigation.

Reporting on sensitivity-label usage and information-protection activity across the tenant.

Visibility into where labeled/sensitive content actually lives and how it moves (Content Explorer, Activity Explorer) — distinct from Sensitivity Labels itself, which covers creating and applying the labels; this is the reporting/analytics layer on top.

Manages regulatory, legal, and business-critical records through their full retention and disposition lifecycle.

Classify content as an official business record with a defensible retention/disposition schedule, event-based retention, and disposition review before deletion.

Scans internal and external communications for policy violations such as harassment, regulatory breaches, or sensitive-data sharing.

Scans internal and external communications (Teams, Exchange, third-party connectors) for policy violations — harassment, regulatory/insider-trading language, sensitive-data sharing — and routes matches to reviewers.

Lets an organization supply and control its own encryption keys for Microsoft 365 data at rest.

Supply and control your own encryption keys for Microsoft 365’s at-rest data encryption layer, so Microsoft can’t access your content without your key.

Online appointment scheduling and calendar management for customer-facing bookings.

A public-facing, self-service appointment-scheduling page synced to staff calendars — common for clinics, salons, and internal 1:1 scheduling.
