We're now using SpamTitan Plus. When we receive an email containing a link, it's checked before it gets to our employees. That's the best feature.
SpamTitan's cloud is the first point where our emails are filtered and then they are delivered to us.
In the past, spam emails were hammering our Exchange Server constantly. But now, it's going to the private cloud first and everything is filtered. The only things that are delivered are what should be delivered. All the spam is stopped on the private cloud.
Another benefit of SpamTitan Plus is the protection from emails that can damage your organization. We had a case before we had SpamTitan, where somebody clicked on an email and as a result, all our files were blocked and the attackers were asking us for money. Since deploying SpamTitan, we haven't had that issue.
