Country Blocking

GB-OS 6.2 features more granular network control with the addition of country blocking. Administrators can now allow or deny access based upon IP address country codes. With configuration selections including countries and regions, organizations can easily fine-tune the level of country blocking needed while maintaining access for those allowed. Administrators can also choose to use a country code whitelist. This whitelist will override existing country block settings. Automatic updates for the country IP database make's firewall management easier and ensures up-to-date country IP identification. The country IP database automatic updates require a valid support contract.

Viewing country data and managing country blocks is simple and intuitive with GB-OS monitoring and reporting features. Firewall administrators can now filter active connections by country to view current activity. In the security policies monitoring section, a counter tracks the number of allowed/denied country blocks for instant feedback and aides in the management of security polices. Reports are also available displaying allowed and denied inbound and outbound connection data by country. The customizable reports, available in daily to yearly time frames, provide valuable insight in a concise format for organizations of all sizes.


GTA has improved and expanded the integrated reporting features in GB-OS 6.2. New report types, graphical data displays and more configuration controls provide system administrators with accurate and easy-to-read data on network activity. New features for GB-OS 6.2 include the ability to save report data to USB devices, the display of usernames versus IP addresses in reports, and the ability to individually turn on or off reporting and logging data for the Mail Proxy and Content Filtering options. These feature improvements provide more user-friendly reports for easier firewall management.

Administrators can generate reports containing all vital information and networking trends for each firewall. Network traffic, VPN traffic as well as data from GTA's Content Filtering service and the Mail Proxy Anti-Spam and Anti-Virus options are available for easy viewing and review. Report options also allow administrators to designate the time-frame for the included data - from the past 24 hours, 7 days, 30 days or even the past year. Reports are available for instant download or can be scheduled. Scheduling reports makes monitoring firewalls easier and more consistent, with reports emailed at the designated time. Historical Statistic graphs are fully customizable, allowing administrators to choose the graph colors that fit a companies needs - whether for easier printing, sharing, or on-screen display.
