Syslog CEF and REST, into the tool you already run

A week in a life.

Five questions that arrive every week, and today take a script, a spreadsheet and an afternoon each.

Monday

Why is this volume full?

Answered byCapacity, growth and file types per share, on a schedule.
Tuesday

Who deleted that file?

Answered byThe audit trail, with user, path and timestamp.
Wednesday

What can we archive?

Answered byHot and cold data, so the answer is not a guess.
Thursday

Who can open this share?

Answered byEffective permissions, including broken inheritance.
Friday

Can you restore just this folder?

Answered bySingle-file restore from the snapshot you already have.
10 PB+
of unstructured data, in four out of ten enterprises.
30 %
of the IT budget goes on storage at more than half of them.
85 %
expect that spend to rise again this year.

What changes on the Monday after.

Installed in 1–2 hours
No agent on the filer, no change to the data path, no maintenance-window argument.
The capacity report builds itself
Hot, cold, growth and file types per share, on a schedule, delivered automatically.
Every file operation on record
Who opened, changed, renamed or deleted which file. Searchable, not reconstructed.
Permission insight
Folder rights by level, broken inheritance and share access — the audit answer without the scripts.
Restore a folder, not a weekend
Single-file restore scoped to what one blocked account changed.
One console for the estate
ONTAP, Dell, Windows and Microsoft 365 in one landscape tree.

And the night you hope not to have.

The same file-operation stream that answers the capacity question is the one that catches an encryption run — in seconds, by behavior, without an agent on a single client.
