Varonis is pulling the plug on on-prem. ProLion isn’t.

The account is blocked. The business keeps running.

6,000+ known ransomware extensions and patterns, plus a behavior baseline per user. When activity matches, the responsible account is cut off from the data automatically — only that one.

Why your other tools do not catch this.

An attacker with valid credentials looks like a normal user to a firewall and to an endpoint tool. Backups are a target themselves, and they do not prevent data theft. The file-operation stream is where the attack is visible first.

  • If a user started encrypting a share right now, how long until you noticed?
  • Which files would already be hit by then?
  • Can you stop one account without stopping everyone else?
  • Would you see an encryption pattern nobody has published yet?

What it does.

Blocklist
Ransomware extensions and file patterns, maintained by ProLion, recognized and blocked the moment they appear.
Pattern analyzer
Mass encryption, renaming and deletion caught in real time — including from ransomware nobody has published yet.
User blocking
The suspicious account is cut off from the data, immediately or after a delay you configure.
Activity zones
Each user’s normal activity is learned; a suspicious user is restricted to it and everything else is blocked. Part of DataGovernance.
Your team hears about it
Syslog, mail, ServiceNow, Slack and Teams — the event arrives where your team already works.
Delayed blocking
For the cases where an immediate block would hurt more than it helps.

Let’s solve your data challenges.

Connect with our engineers to find the right approach for your infrastructure.

Data-native, by design.

Detection runs on the file system’s own file-operation stream, so there is no scan to wait for and nothing to install on a client. 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.

Talk to an engineer who knows your data.

Four fields, and somebody who knows ONTAP, PowerScale and what FPolicy does. Not a qualification call.

Four fields. No hidden newsletter.
