Six things the platform does.

See what data you have, know what is in it, know who can reach it, find the permissions that are quietly broken, stop what should not be happening, and put back exactly what was hit. One appliance, two packages.

NetApp

Syslog CEF and REST, into the tool you already run

The one everybody has.

Broken permissions

Every file estate accumulates them: a folder cut loose from its inheritance, a person granted access directly instead of through a group, an entry for an account that was deleted three years ago. None of it shows up in a group review, none of it triggers an alert, and all of it is still live. It is the single most common finding when we first scan a landscape — and the one that turns a single compromised account into a company-wide incident.

  • Broken inheritance
  • Direct permissions on files
  • Orphaned SIDs
  • Everyone and Domain Users
  • Nested group loops
  • Stale and disabled accounts

Wherever your data already sits.

Each system is read through its own native interface — FPolicy on NetApp ONTAP, CEE on Dell, the ProLion Security Service on Windows Server, and the Microsoft 365 audit log and APIs for SharePoint Online and OneDrive. Lightweight collectors sit in each data center. Nothing is installed on endpoints, and everything runs on your own hardware, including at dark sites.
