Overview

Qualys SSL Report Grading for PRTG is a custom PowerShell script that queries the Qualys SSL Labs Service and allows you to grade a (public) web property's SSL Settings

Installation

  • Copy the *.ps1 and *.psm1 files to the PRTG Network Monitor\Custom Sensors\EXEXML folder on your Probe(s) where you want to use the Sensor from.

  • Copy the *.ovl files to the PRTG Network Monitor\lookups\custom folder on your Probe(s) where you want to use the Sensor from.

  • Create a new Sensor of type EXE/script Advanced (Make sure you use Advanced!)

  • Give the Sensor an appropriate Name (e.g. SSL Grade)

  • Select QualysSSLReport.ps1 in EXE/Script

  • Use -ServerName %host as a parameter, which uses the hostname of the parent device, or specify a name directly using e.g. -ServerName microsoft.com

  • It's a good idea to set a Mutex to not overwhelm the Qualys API or get throttled when you have multiple sensors with this type. Use e.g. michelz.prtg.qualys.mutex as value

  • Set the timeout to an appropriate value (it's not uncommon that this scan takes 10 minutes - so we recommend at least 600 seconds)

  • Set the scanning interval to something very low, like 6 hours. We don't want to overwhelm the Qualys API or get throttled. The result also doesn't change often. Use at least 1 hour.
