I'm the one who started this thread, and this is the first chance I have had to read since it began. What a lot of strong opinions!
What originally made me ask the question are:
I do not like the web filtering we get from CLEO. It is very restrictive on a number of sites that staff really want to use (YouTube for instance) and inadequate for things that need restricting (flash games for instance). To address the second part of the issue, we bought a SmoothWall Network Guardian so we could have control over what is blocked, but this is an industrial-strength web filter which means we don't need CLEO's.
I do not like having to do security in CLEO's way. I want to serve my own content on my own web server. If I was a Systems Manager in the "real" world I would open up which ports I want and off I go, but with CLEO (whom we pay to provide US with a service) I have fill in a request form, tell them what I want it for, and then only get a reverse proxy allocation. It's as if I work for them, instead of the other way around.
I have a router, I've done a CCNA, I have lots of experience, I have VPN-capable switches, I configure firewalls, I use Group Policies... I've got the skills, but not the freedom.
Anyway, the question I originally asked was if anybody has switched, and what their experiences were. Any takers on that question?
