Featured Reviews

It gives clients peace of mind and helps them educate their users about threats
A few years ago, our team found the implementation to be somewhat challenging. It has gotten easier as we've grown more experienced. The difficulty depends on the expertise of the person doing it. I don't work with Mimecast every day, so it might be more difficult for me than it is for one of my techs who regularly does Mimecast implementations. It requires some specific in-depth product knowledge and an understanding of email solutions. The deployment time varies. In South Africa, it depends on who you use to deploy it. If you use one of Mimecast's local partners, it can take up to two weeks because of their process. However, it's only about four to eight hours of work. After deployment, there isn't much maintenance aside from supporting and educating your customers. Users require constant education on how to use the Mimecast client and release an email that has been blocked.
NaveedAli - PeerSpot reviewer
Provides good identity proxy features, but sandboxing and spam control features could be improved
Sophos gives you a feature set to manage your on-premises firewall on the cloud. I just integrated my on-premises firewall into the cloud, and I can manage the tool through the cloud as well if needed. I recommend using Sophos Email as a proxy. For email gateways, I advise choosing mature products with rich feature sets, like Trend Micro or CrowdStrike. The solution's integration with other tools is very simple. I easily integrated Sophos Email with my Active Directory. My organization needs a WAF with a limited feature set, which we use through Sophos. Purchasing additional WAF will be costly, but I get sandboxing and WAF features free of cost with Sophos, which is included in the license. Overall, I rate the solution a seven out of ten.
