O2 Security's SifoML S200 is a hardware-based appliance for managing and securing email content. The device is available in various hard disk size configurations and offers anti-malware, anti-spam, anti-phishing and many other features.

Installation of the product is easy. We had the device up and running within our test environment in just a few minutes. One small item we noted was that the device contains two URL paths. One is for administration of the device, but a second is used for reporting purposes.

The interface for the administrator side of the device is fairly easy to navigate and use. All of the features are configured on the left-hand side of the page, with the middle portion of the interface sorted in a tabular format. From a performance perspective, we noticed that the device consumed a large amount of memory.

The appliance has all of the features one would expect: anti-malware, anti-spam, anti-phishing and a compliance module for customizing content analysis based on attachments, sizes, volume and other items.

The solution does not come with any pre-defined dictionary templates or rules that can be activated out of the box. From an administrator perspective, backup and restoration, automated reporting and other tasks are easy to configure and perform. However, we're not sure why the appliance contains two URL paths since neither is accessible from the other.  

Documentation is adequate, although a bit on the short side. Most functionality is explained throughout the different help files.

O2 Security offers email- and phone-based support via eight hours a day/five days a week and 24/7 options. The website has a customer portal that contains documentation and other useful items.

The cost is a little on the high side given the customizations that administrators will have to do since the appliance does not ship with pre-built dictionaries and templates for content filtering.
