But SharePoint is also a major data exposure surface when tenant sharing policies, guest access, unmanaged device controls, authentication settings, or site permissions drift from security baselines.
Reach analyzes SharePoint tenant sharing settings such as [SharingCapability] and [PreventExternalUsersFromResharing] to identify expanded external sharing or resharing permissions. This helps prevent external users and guests from distributing sensitive content beyond intended audiences.

Reach detects drift in controls such as [BlockDownloadOfAllFilesOnUnmanagedDevices] and [BlockDownloadOfAllFilesForGuests]. By restoring these restrictions, Reach helps prevent sensitive files from being downloaded to unmanaged devices or external guest environments.

Reach identifies risky changes such as [LegacyAuthProtocolsEnabled] being turned on or [AllowAppsBypassOfUnmanagedDevicePolicy] being enabled. These misconfigurations can bypass MFA, conditional access, and device-based controls, increasing exposure to credential attacks and unmanaged app access.

Reach analyzes site-level settings such as [RestrictedAccessControl], restricted access groups, and [DefaultSharingLinkType] to identify weakened controls on sensitive SharePoint sites. This helps preserve intended access boundaries for executive, security, and company-wide content.
