ShareFile Virus Strictness explained

ShareFile Virus Strictness

When using the SFAntivirus scanning option within your On-premises StorageZone, you have the option to use ShareFile Virus Strictness.

What is it?

Virus Strictness is a method of authorizing access to your ShareFile data depending on the outcome of the SFAntivirus scan. 

You don’t need to switch it on within the ShareFile Control Plane or ask Citrix Support if they can enable it, Virus Strictness is enabled by default for On-premises and Citrix Cloud StorageZones. The only requirement is that you have the SFAntivirus option in place for the On-premises StorageZone.

Virus Strictness Levels

There are three levels to choose from. These are:

0: warn only when trying to send/download infected file
1: block sending/downloading infected files
2: block sending/download infected AND unscanned files, will also show icon next to unscanned files

Level 0 is the default. 

How does it work?

When you use the SFAntivirus option to have your On-premises data scanned periodically, and not use an On-Access virusscan on the location of your ShareFiles’ network location, Antivirus information on the scanned files is reported back to the ShareFile Control Plane.

If the file is free of viruses, nothing happens and users are able to use it. However, if a virus is being detected the file is flagged. Depending on the Strictness Level of your choosing a warning about the file is being shown or access to the file is being denied.

Remember that if you choose to go for Level 2, users are only able to use the uploaded file after the next scheduled SFAntivirus task has run. You can switch to Level 1 or 2 by requesting Citrix Support for the change.

If the data are stored on the Citrix Cloud, Antivirus scans are run by Citrix where Virus Strictness will take action.

I hope this article gives you some insight on this feature.
