I used to use this software everyday in my job as an IT admin, it's very easy to install and configure with our network antivirus products (Eg Kaspersky). We had problems when we moved from Windows Server 2008 R2 or 2012 server/workstation OSes to newer versions of windows 8 / 10 that did not support these older AVs. The customer service is also amazing! They are always willing to assist you until they get everything working again. This program works great even if your firewall blocks some ports in order to allow viruses through them. It does have its limitations but there isn't anything major about this product at all. If you're looking into purchasing any security programs make sure you check out their free trial version first so that you can see how well the application fits within your environment before making any final decisions. You should be.
