Which is more desirable for server-side virus protection for emails? A hardware appliance or software app.?
We bought Exchange Server and will be deploying it soon. We just need to decide on virus protection for our incoming emails. The two contenders so far are the Barracuda Spam Firewall 200 and GFi MailSecurity. We have about 80 users.
To me, the advantages of each seem to be as follows:
GFi MailSecurity is primarily designed specifically for virus scanning and comes with 2 good virus-scanning engines (and we already have a Bayesian spam filter that does well for us, so we do not necessarily *need* spam filtering).
The Barracuda costs less initially, costs less per year to maintain the updates, and does not take up resources on any server.
To me, the cons of each seem to be as follows:
GFi is a little more expensive.
Barracuda seems designed primarily to filter spam and scans for viruses as a secondary objective. (It is a Spam Firewall).
If suggesting a different product altogether, just remember we are on a budget–and that is why you do not already see Trendmicro listed.
