I previously wrote about processing .Nessus files using Posh-NVS. I found my needs to be a little different from what that project provides, so I decided to take a crack at my own script for reading .Nessus files. Unlike Posh-NVS, it has no modules to install and my Convert-Nessus.ps1 adds the host information onto the line with the vulnerability data. Although it creates a larger file, it is nice to have the IP Address, OS, MAC addresses, and NETBIOS Name in the same line for the file. Update: Convert-Nessus4.ps1 adds a GUI to select what properties you want in the output.
