Get a grip on communications slips
Code Green, InBoxer, MessageGate, and Palisade compete to prevent costly data loss
Beyond the system's general multi-step identification algorithms, you can match specific data, such as structured information, in databases. The process isn't as extensive as I'd like; for instance, PacketSure does not crawl document repositories. Still, this feature ensured that my test list of client account numbers was available for matching. I liked Version 5.5's recognition of private health care information -- a feature that's turned on with a single checkbox.
The ERE (Extended Regular Expression) function recognized Social Security numbers, and it can be customized to look for other types of structured data. Moreover, the Web Filter function contains approximately 14 million Web sites (organized by category) that you can block, monitor, or ignore.
The overall Web interface, while certainly functional and generally easy to navigate, could still use some improvement. For instance, lists of rules and reports are especially long, which sometimes makes it hard to find specific information.
In running through my test scripts (Outlook IMAP E-mail, Hotmail, MSN Messenger, and FTP), PacketSure did a very good job logging, blocking, or allowing communications based on rules. In addition to recognizing risky message content, the system correctly analyzed different files types for private content, including Microsoft Office documents, AutoCAD drawings, and MP3 audio files.
When a violation occurs, PacketSure notifies the sender and (optionally) an administrator. On the presentation side, 60 predefined reports can be customized as needed and saved. I created a query that displayed matches by several rule names and had PacketSure e-mail me this report each day. However, I would like to see a search function to find particular incidents.
As I delved into online versions of different reports, the software showed specifics of each security problem, including the content of attachments that triggered the incident. Yet performing these steps did involve opening different windows and PacketSure lacks the formal workflow of Code Green Networks. Other reports provide summary and trend charts so you can track how your compliance efforts are going along with the underlying details that may be required for compliance audits.
The PacketSure network appliance holds several advantages, including visibility into everything going over your network and the ability to eliminate unwanted protocols and applications. This system helps protect private data by monitoring for several types of information and blocks where appropriate. Therefore, it's appropriate for complying with many government regulations and keeping intellectual property secure. Still, compared to other products, it doesn't have the same level of resolution functions and forensics.
This roundup showcased the many facets of data loss prevention. For clamping down on badly behaved applications or protocols, Palisade PacketSure's got you covered. InBoxer and MessageGate focus on e-mail governance with a vengeance. Yet it was the all-around protection and performance of Code Green Networks' Content Inspection Appliance that nudged it ahead.
