SharePoint Online and OneDrive.

New on the ProLion Platform. The same audit trail and permission insight you have on-premises, extended to where the files went.

Connected through the Microsoft 365 audit log and APIs

How it connects.

SharePoint Online and OneDrive are read through the Microsoft 365 audit log and the Microsoft APIs, and joined to the same landscape tree as your on-premises systems. Register a system and the platform discovers its topology. Monitoring runs through the file system’s own interface, by way of lightweight collectors in each data center, and analysis scans run on the schedule you set. Nothing is installed on endpoints, and everything stays on your own hardware, including at sites with no outbound connection.

What you get on Microsoft 365.

One record, both worlds
A file that moves from a Windows share to SharePoint keeps one audit trail instead of starting a new one.
Permissions that sprawl
Sharing links, guest access and inherited site permissions, resolved to what actually applies.
Classification
Personal, health and financial data found in SharePoint Online and OneDrive — analyzed on your own hardware.
Permission audit log
Every permission and ownership change, recorded as it happens.
Before the copilot reads it
Microsoft 365 Copilot answers with the permissions of whoever asks. Fix the permissions first.
Evidence for the auditor
Findings mapped to GDPR, NIS2, ISO 27001 and DORA, for the cloud side as well as the on-premises one.

Your tenant, your analysis.

The files are in Microsoft 365, but the classification is not: content is analyzed on your own hardware, not handed to a cloud service to read. Which is the point of doing it at all.
