Data loss prevention comes of age

Much of the configuration work had been done prior to McAfee shipping the products. Our part of the DLP setup consisted of wiring up all four of the DLP appliances, including giving the NDLP Monitor device a network tap connection (which we chose to place between registry cleaner reviews our DMZ and its gateway), giving the technicians IP addresses to use for all of the services, and helping them to integrate their product into our Active Directory setup.
We had the opportunity to get a more hands-on impression of the installation of Sophos' software, and were very pleased. The ES1100 appliance came with a very easy to digest quick start guide. This gave us the information we best registry cleaner needed to initially connect to the device and initiate the configuration wizard.
This wizard was one of the best we've seen. It was well designed, provided helpful information at each step, and did a number of checks to verify proper configuration (even testing to make sure its network connections weren't cross-wired). The only issue we ran into was that, in our isolated environment, we didn't have a connection to the Internet. The product needs to be able to connect back to Sophos to test its connectivity and download a large (200MB) license file. We were able to get around this using a proxy server.
Sophos also gives the administrator the option to relay status information about the ES1100's health back to Sophos. The administrator can elect to receive notifications if a critical or non-critical error (or both) is detected. This proactive support could stave off a major service interruption, but the exact criteria for these alerts are not defined so it's hard to say for sure.
Installation of the Sophos Enterprise Console was also quite easy (though it too requires an Internet connection for activation and updating). The only issue here was that the _updatemanager, which must be run before the software can be deployed to clients, does not yet support Windows registry cleaner Server 2008 R2. We sidestepped this issue by running it in Windows XP compatibility mode, and Sophos has advised us that the next version of the software will support 2008 R2.
Rollout of the client to endpoints is eased by the ability to synchronize the client list with Active Directory, and automatically deploy the software to new computers. One issue we ran into was that the updater uses a Windows file share to fetch updates, so firewall rulesets and share permissions will need to be configured accordingly.
Existing Sophos customers will be pleased to know that the DLP software makes use of the existing Sophos client software, so adding DLP is only a matter of rolling out additional rules. Sophos uses the same engine for both antivirus and DLP.
