+3Hi,
We need a way to stop dummy eicar malware files being downloaded from online in Chrome, Edge and Safari.
It looks like Jamf Protect or Jamf Radar can not do this. It can only stop the files being executed after they have been downloaded to the Macbook. Is there a way we can implement download restrictions using Jamf Pro?
thanks
+25@ssrai20 Jamf Pro does not have any built-in capabilities for restricting downloads. You could use it to install a tool if you find, or write, one to do that, but it's not going to do it by itself.
+5To prevent common Malwares I'm using a combination of EA, Smart Group and Script.
For example Mackeeper :
The EA :
#!/bin/bash

result=()

exitA smart group is populated with "YES" and then a script to remove then is executed.

+26JAMFs products all operate on the device level. EDR clients are responsive by nature, to prevent the file from getting to the device you need a network security tool. A network security tool can inspect traffic in flight, and quarantine traffic with malicious or undesired content.
