Syslog CEF and REST, into the tool you already run

One platform, and what it is measured on.
Security starts where the files are.
Every other layer guards a route to the data. The data layer is the one the files actually sit on — and the one that usually has neither an owner nor a budget. That is where ProLion runs: on your hardware, in your network, reading every read, write and delete as it happens.
The permissions, not the model
A copilot answers with the permissions of whoever asks it. Fix what is reachable and you fix what it can say.
A report does not stop an attack
Findings tell you where the risk is. At three in the morning what counts is the block, the snapshot and the restore.
Nothing leaves your building
An Austrian company, running inside your estate. No vendor tenant holds your file data, and dark sites are supported.

Data security posture management is six jobs in three pairs, not one. This is the whole list, and where we stand on each.
Discover
Every share, volume and folder in the estate — including the ones nobody owns.
Classify
What is actually inside the files: personal, health and financial data, intellectual property.
Access
Who can reach what, where that is more than they need, and where inheritance is broken.
Monitor
Every file event, retained and searchable.
Detect
Mass encryption, abnormal collection and permission drift, caught in real time.
Respond
Block the account, quarantine, snapshot and roll back the affected files — in one take.
Fits wherever your data already sits.
NetApp, Dell, Lenovo and Microsoft — read at the data layer itself, with no agent on the file server.
Talk to an engineer who knows your data.
Four fields, and somebody who knows ONTAP, PowerScale and what FPolicy does. Not a qualification call.
