Overview
Saner CVEM allows administrators to attach Pre-Scripts and Post-Scripts during patch deployment to perform custom actions before and after patch installation.
This provides flexibility for automating tasks like stopping services, backing up files, or restarting applications after patching.

Steps to Add Pre-Script and Post-Script

Go to Patch Management (PM) from the left navigation bar.

Here, you’ll see the list of patches detected across your endpoints.

Patch Name, Version, and Release Date
From the left panel, select Remediation Scripts to access the script upload section.
4. Upload Pre-Script and Post-Script
Under Remediation Scripts, upload your desired files:
Pre-Script: Executes before the patch is installed.
Post-Script: Executes after successful patch installation.
Saner CVEM supports the following file formats:
| Operating System | Supported Formats |
