Get a grip on communications slips
Code Green, InBoxer, MessageGate, and Palisade compete to prevent costly data loss
The archive option is especially important. First, MessageGate decides if e-mail should be retained. If so, Archive Categorization tags messages with information you configure, such as department codes or litigation holds. At this point, messages are sent to a designated spot (such as a Microsoft Exchange Journal folder), where the e-mail is archived as part of standard backup procedures. I was initially concerned that adding the meta information changes the message so it might not meet the evidence requirements of the Rules of Civil Procedure. Upon further examination, however, I've changed my view. Although MessageGate does add metadata to the x-header of the message to indicate how it is archived, I could see nothing that indicated the message itself was altered in any way.
MessageGate Enterprise Email Governance provides very effective e-mail management and control. It lets you educate users with informative messages when policies are broken -- and actively handle some problems on the spot, such as inserting disclaimers into messages. The system also takes a more proactive stance whenever necessary, such as blocking message transmissions that are out of bounds.
Although the system doesn't have the elaborate data registration of other solutions, policies can cover most compliance needs; they worked accurately in my testing. MessageGate also has some of the most sophisticated categorization for message archiving. However, this solution doesn't provide for monitoring of Web mail, instant messaging, or other forms of network traffic.
Palisade PacketSure 5.5

New to version 5.5 is SMTP e-mail analysis, plus options to block or encrypt the e-mail when violations are detected. Also, Palisade Systems added lexicons of common words and phrases used in the health care and financial industries, which improves detection accuracy. And the Web user interface was reorganized, making setup and configuration easier.
The PacketSure appliance, similar to other solutions, quickly connects to a network port or tap. I used the latter method to fully test the system as an e-mail proxy so messages could be blocked or encrypted.
Rather than specific policies, PacketSure ships with a long list of default rule sets and file analysis enabled; these range from monitoring HTTP file transfers and trapping file-sharing application to checks of instant messaging and Web-based mail. I tweaked various rules with a Web form, such as blocking Hotmail when files over a certain size were encountered. If you want to make more global changes, the Rules Wizard saves time. For instance, I selected the main Instant Message category (which covers all the major IM clients and protocols), allowed communications, and in the final step selected the type of content analysis to apply.
