Webmail Lockdown


We are looking for a solution to allow us to restrict users from uploading attachments to webmail (For example hotmail, gmail and so on). We are currently using Sophos Web Appliance which has a fucntion call web applicaiton control, however it only supports a small list of webmail sites. There is also a Korean product called Waterwall which will allow us to do exactly that, but its over $300 per pc (at over 150 onsite computers it's quite costly) So ideally we are looking for something more cost effective?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

We solve it this way:

Let them use RemoteApp browsers. That means, they are not connecting to the internet from their own computer but from a remote server. It looks like local, but it isn't. Consequence: you can tune that remote server so that it is totally isolated, no file access possible, no attachment upload, nothing.
Very cost effective, we use it. You need to buy a server license and enough rdp licenses, will be less than 100USD per seat in total.
