Enhances web security with a single pane of glass and flexible deployment
I don't see any need for improvement; one of the really good things about iboss as a company is that they listen to customer feedback. I have suggested enhancements, and they are responsive, making changes for the better, and they do a lot of testing. To improve iboss, although we haven't used it, we considered the VPN solution that comes with the highest tier licensing, which includes DLP and various other add-ons. We prefer using another product which automatically logs you back onto your network when turning on your PC. With iboss, the connection is manual, which doesn't meet our needs. Additionally, sizing can be tricky because, although the initial recommendations may seem adequate, actual usage may require more gateways than anticipated.

Email Security Engineer at Logic Infosecurity
Experience high detection and user-friendly policies with reliable email security implementation
The system is not user-friendly because you have to create policies that are mapped in a dictionary. As an IT engineer, I understand how it works, but explaining it to another IT person can be difficult. Having more user-friendly dashboards would improve the work experience. In Mimecast Email Security, checking policies in the dictionary or gateway is very complicated, and not everyone understands this process. If you examine the Check Point portal, it's user-friendly with easily accessible tabs that anyone can explore. With Mimecast Email Security, making changes might impact existing mailboxes. The portal is complicated compared to Check Point's user-friendly interface.
