Clearswift's MIMEsweeper Email Appliance is a rack-mountable hardware device that secures inbound and outbound messages. The features available in the appliance include anti-malware, anti-spam, content filtering (including smart identifiers to help prevent data leakage), anti-phishing and many others.
Setup and configuration of the tool was very easy. We had the device up and running within minutes and found the overall interface to be attractive and professional looking.
When reviewing email content management, we look for many defense-in-depth features and this appliance definitely delivered. Overall, it includes one of the largest ranges of user-friendly feature sets that we've seen. Several configuration items are linear, which helps administrators understand what policy or configuration they are applying and to which groups or users.
The solution integrates with directory services and secures messages by using a combination of techniques. This includes network-based integrity via reputation and sender validation, but also content management, including anti-malware and smart identifiers. A few pre-built identifiers can be applied to filter messages for special data strings, such as credit card and Social Security numbers. The appliance also has several enterprise management features, such as automated report scheduling, backup and restoration capabilities, audit logs and more. Navigating around the interface did take a slight learning curve, but after consulting the documentation we were quickly acclimated to many of the administrative tasks.
Documentation is thorough, extensive and is available on the appliance interface, as well as offline.
Several support packages are available, including basic phone and email support, which is included with the cost of the solution. The website contains a dedicated support page for its customers.
