Global Technology Associates’ GB-2000, GB-2000e & GB-2000X Firewall Appliances provide powerful enterprise-level security with comprehensive features, including support for Mail Sentinel anti-spam and Mail Sentinel anti-virus, that are easy to implement and support in most corporate network environments.
Email spam and computer viruses can bring your network to a halt. Lost time means lost profits. Mail Sentinel anti-spam and anti-virus fortify your gateway defenses by filtering spam and viruses entering through the firewall’s email proxy. GTA licensed the technology from market leading companies such as Mailshell’s SpamScore technology that executes more than 300,000 checks to determine if a message is spam; and Kaspersky Labs who are noted for their exceptional detection rates and responsiveness to virus attacks. There’s no additional sofware to install or learn, simply enter the subscription activation code on your GTA firewall, and confi ure using the GNAT Box OS web or windows interface.
GTA firewall products combine a proprietary operating system - GNAT Box OS - and hardware into one-easy-to-install, dedicated firewall appliance. Offering multi-layered features, network administrators can choose from a simple plug-andplay implementation or customize most feature settings for a more flexible implementation. GTA firewalls combine both standard and advanced features into one easy-to-use appliance.

The GB-2000, GB-2000e & GB-2000X enhance your perimeter network security with optional features like H2A – High Availability, Surf Sentinel 2.0 Content Filtering and Mail Sentinel anti-spam and Mail Sentinel Anti- Virus.
