I like that this is able to scan my files/apps without me having any knowledge of what it's doing behind-the scenes! This also has some great reporting features which helps organize your findings by severity level or type so they can be easily found later when needed.
It doesn't always pick up all issues but once these are fixed we're notified immediately allowing us time make sure there aren’t more problems being overlooked elsewhere within our infrastructure. If anything else were improved upon then maybe adding one specific function would help with finding solutions faster after an issue was identified? We've been using both MOSS 2007 & SharePoint 2013 along side other servers such as Windows File Servers / Web Applications etc..
