Hi aaa_9116,
Yes, the Norton Business Suite is a Comcast offered Product and is in fact Norton Internet Security Online. Following is a post I made in Feb 2013on the Comcast Forums:
If you read that post and follow the here. you will be taken to the Comcst Business Page. Once there follow the link to Visit Cloud Software Marketplace on lower right of that page. Click on the Go to Upware Marketplace button on the popup.
Then click on the Norton Icon and you will finally end up on this page:
https://upware.comcast.com/apps/4352#!overview
From there you can gather the information you desire. Specifically the Editions and Pricing Tab on that page will tell you about the options in regards to licenses.
I have no answers as to why Comcast changed from the N 360 cloned version to this version of Norton - but can venture a guess that it had something to do with Norton Security Suite not having an online capablilty.
Anymore info your need would have to come from Comcast or Upward Marketing.
