I'm an advocate of AV at the gateway, mail server and desktop. In fact, I'd argue that if a virus gets as far as the desktop, something went wrong. Here is an option, if cost is your problem: 1. At the gateway, you can use DNS blacklists like Spamcop to drop connection from "known bad" sources. This will remove most bad traffic. (This can also be done at the mail server, of course.) 2. Exchange 2003's own spam filter is pretty good, and free (and is essentially what they use for Hotmail, so it has millions of users "giving feedback"). 3. AntiVirus on the Exchange server will take out a LOT of "virus" messages in times of outbreak, which fill users' mailboxes. Between the three, you should have a pretty decent "free" AS solution.

Am getting ready to run install a complete email system (Exchange server) for approximatley 175 users. For antivirus we are currently running Trend company wide and it has served us well. We currently have no spyware solution to filter web traffic. My plan is to purchase Norton 8200 Antivirus & Antispam firewall (applicance) and to put Trend Scanmail for exchange on our server. Figured that that might be overkill int the antivrus department and here is why: Clients-Trend Micro Exchange Server - Scan Mail for Exchange Gateway Solution - Norton 8200 Spam-Virus Firewall. What I was thinking of doing was just puttting regular antivirus client on Exchange and using the saved money to purchase an anitspyware appliance from Barracuda Networks. I would think that two layers of virus protection (gateway, client) would be fine and three layers (gatway, email server, client) may be a bit much for a small-medium environment. In my last exchange deployment several years ago I had it set up with regular cleint on exchange server and a gatway solution. Of course years ago things were a bit different. Any opinions would be much apprecaited. --------------------------------------------------------------------------- EARN A MASTER OF SCIENCE IN INFORMATION ASSURANCE - ONLINE The Norwich University program offers unparalleled Infosec management education and the case study affords you unmatched consulting experience.
