Despite the efforts to keep Web intruders out with network perimeter security solutions, hackers still gain access to even the best protected corporate and government Web servers, exploiting these opportunities to vandalize Web sites, crash servers, corrupt transactions, and wreak havoc. The problem is many of these solutions were never designed to defend Web-based attacks, nor do they limit the public damage if and when hackers get in, a highly probable event. Gilian’s G-Server offers a solution that guarantees absolute Web application and content integrity.

Gilian’s G-Server is the first and only appliance designed to keep fraudulent information and corrupted transactions from ever being published on your Web site. Guaranteed. Based on revolutionary ExitControl™ technology, the G-Server scrutinizes, in real-time, every object leaving the Web server, assuring all content—static or dynamic—as well as all Web applications are authentic and unaltered. Any misrepresented data is seamlessly replaced with authentic, original content. As a result, even if hackers get in, you can be certain your Web audience will only see what you intend them to see. No downtime and no need to post “Site Unavailable” messages. All attacks are neutralized leaving your reputation, liability and credibility safe and sound.

Two-Way, Comprehensive Web Site Content
and Application Protection
Up until now, no product could protect and monitor incoming HTTP and HTTPS traffic, and also validate that applications and pages are being published only by authorized persons. Two unique G-Server features, G-AppPROTECT and G-AppWATCH, meet this need by examining all HTTP and HTTPS requests to ensure legitimacy, as well as preventing Web applications from executing corrupted transactions. So, not only does the G-Server protect your Web server from publishing unauthorized, altered or fraudulent information, it serves as a multi-function Port 80 and Port 443 protection appliance that quickly and efficiently authenticates incoming HTTP and HTTPS requests. This vital capability prevents virtually all “Code Red” and “Nimda” style attacks from ever reaching the Web server to do their damage.

Scalable Web Site Protection
When it comes to Web site integrity, one size does not fit all. Which is why Gilian offers two G-Server models designed to accommodate a full range of Web server protection performance needs: G-Server 200R and G-Server 200XL. So regardless of your industry or your requirements, the G-Server offers the performance level that is right for your organization.

How It Works
Authorized publishers of your Web site’s content create digital signatures for all new or revised Web objects—such as HTML pages, GIF files, or JPEG files—and store these on the G-Server. Located in your DMZ, at the exit point to your Web server, the G-Server intercepts all content traveling to and from the Web server, verifying its authenticity with digital signatures. Only approved content is allowed to be published.

• When the digital signatures match (authentic content) the data is immediately sent to the user.

• When the digital signature fails to match due to altered data, the content is automatically replaced with a backup of authentic content, which is stored on the G-Server, and forwarded to the user.

Administrators are instantly alerted to any discrepancy via phone, pager or email. As a result, they can take immediate action or address the problem at a later time given that the G-Server is providing continuous 24x7 protection. The G-Server is also IP invisible, so hackers cannot detect or attack the system on the network. Instead, they’re left frustrated, unable to determine why your site is impenetrable. Users receive original data, oblivious to any breach and with no significant delay. In addition, the G-Server’s log files enable you to track down issues and pinpoint the exact files that were changed, at what time, and, in most cases, by whom.
