Pricing that is competitive, excellent technical support, and email security
They do a better job of distinguishing between what's real and what's not than most of the other solutions we've tried. They are very easy to use. We don't have as many problems with email security. They have some areas that could be improved. For example, we also use Zix email Encryption for email encryption, which was clunky and could be improved, but the email security itself has been excellent.

Cons

"It needs to make sure that the application is up to date with new attacks. They should also send us the demo or introductions for their new incoming features."
"Technical support is no longer as good as it once was."
"Email security checks contain a small number of false positives."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"It would be great if Kaspersky could do what Sophos does for us. However, we love having these two different technologies doing the same thing. Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"I have only made contact via email, and it is a little slow. I would give customer service a rating of six or seven. Improving Spanish support would greatly benefit users."
"The solution is not 100 percent stable and that can use improvement."
"The biggest problem in the solution is related to its license renewal since it is pretty hard in Kaspersky to find out the procedure to renew a license."
"The stability of Kaspersky Security for Mail Server is okay, not so much of an issue."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
 

Pricing and Cost Advice
