Licensing Background Information: The campus (OIT) purchased 3,700 Sophos Anti-Virus (SAV) licenses back in August 2010. The specifics were 3,700 on-campus licenses (and up to 3,700 licenses for use on off campus staff computers) for 3 years for $15,000. So, the cost per seat is $1.35 per person per year. These licenses will expire August of 2013. OIT picked up the entire cost of the purchase at that time.
Non-Managed Systems Server Background: Around seven years ago, a standalone server was created to provide "unmanaged" access to anti-virus and adware signature updates from a central Sophos server that OIT managed. The idea was that local computer support could provide configuration for the anti-virus product on users desktops and really only needed access to engine and signature updates. So, it was decided to provide department-level credentials to user groups on campus to allow them access them updates from the central signature server. However, this unmanaged server is, now, coming to the end of its useful life. Further, this server is now providing services that are redundant to other anti-virus services being provided on a "managed" basis for the campus from within OIT.
Managed Systems Server Background: With the creation of the Windows Services Group (WSG) in 2010, certain specific commodity services were identified between the Help Desk, Desktop Support and Windows Services Group that should be combined into a single instance on campus so that redundancies could be reduced and a more comprehensive product expertise could be introduced to those services that may not have been possible previously. A central Sophos Enterprise Console instance was brought up for WSG and the central instance that Desktop Support was managing was decommissioned after the client base was moved over from their instance of Sophos Enterprise Console to the WSG version. However, the "unmanaged" version of the Sophos server and the Sophos server instance that is being managed in the Instructional Labs area of OIT still continued to provide service to their respective clients.
