So, how does it work? GB-OS hides your internal network from unauthorised users. The network address translation system also offers stateful packet inspection and advanced routing. Resilient threat management locks down intruding networks while simultaneously protecting resources. This threat management consolidates IPS (Intrusion Prevention System) with Mail Proxy, web content filtering and anti-spam and anti-virus options.


Available products include:

  • Hardware Firewalls – GB300, GB-850, GB-2600
  • Software Firewalls – GB-Ware
  • Enhancement Options
  • Web Content Filtering
  • Secure Remote Access
  • Mail Proxy/Anti-Spam
  • Intrusion Prevention

What Makes GTA Different?


Unlike most firewalls, the GB-OS is easy to use and can be implemented across all GTW firewall systems. It also provides users with transparent network access to external and private service networks for IP protocols (TCP, UDP, and ICMP) applications.


Additionally, GB-OS supports Dynamic Gateway Architecture with WAN failover, along with advanced routing protocols such as OSPF, BGP, and RIP.


Finally, Mobile IPSec VPN Client, PPTP, L2TP and the GTA SSL Browser and SSL Client provide convenient remote access. Laptops and mobile devices such as iPhones and Android-powered phones are all easily and seamlessly protected.
