Upgrade a GTA Product

GTA releases new version of our firewall operation system - GB-OS to provide our customers with new features and/or address identified issues. GTA recommends always running the most current GB-OS version available for your firewall to ensure the highest level of security.

To determine the most current version available for your firewall, check your firewall information in the GTA On-Line Support Center. If you have not yet registered your product, please complete the product registration.

If your product is eligible for an upgrade, you may download the runtime through the GTA On-Line Support Center. For detailed information on upgrading your GTA Firewall, please review the documents below.

Please note: If you are upgrading a GTA Firewall to GB-OS 4.0 from either GB-0S version 3.4.x or 3.5.x, it is first necessary to upgrade to GB-OS version 3.7.x, prior to upgrading to GB-OS 4.0.
