GIS Sentinel Spam Firewall

Freedom from SPAM, freedom from e-mail born viruses, it's enough to make you do flips!

Global Internet Services, Inc. is proud to introduce the "GIS Sentinel Spam Firewall" service. A free spam and virus scanning service using the Barracuda Networks Spam Firewall appliances.

Mail is directed to our Sentinel Spam Firewall server before it reaches your mail server. Once Sentinel scans the message for all currently known virus & trojan file attachments, it then tests against an entire battery of SPAM identification rules. Depending on the score your mail receives from this process, your message is forwarded on to the original recipient in its' original format, quarantines for further analysis by you or has the Subject line tagged with identifiable text stating we've found a virus or what appears to be spam.

The GIS Sentinel Spam Firewall design leverages open source virus and spam solutions in conjunction with ten defense layers:

• Denial of service and security protection
• IP block list
• Rate control
• Virus check with archive decompression
• Barracuda virus check
• User-specified rules
• Spam fingerprint check
• Intention analysis
• Bayesian analysis
• Rule-based scoring

The methods and techniques used by the GIS Sentinel Spam Firewall are constantly updated (via hourly signature updates), to keep up with changes that spammers and virus writers are constantly making.
