Because the operating margins of small- and medium-size businesses are so slim, these operations can't afford downtime. To improve business continuity for these SMBs, Untangle Inc. developed the open-source Next Generation (NG) Firewall, which is now in version 10.1. NG Firewall is a next-generation platform for deploying network-based applications. The platform unites these applications around a common GUI, database and reporting. NG Firewall's applications inspect network traffic simultaneously, greatly reducing the resource requirements of each individual application. The new version 10.1 now provides high availability via virtual router redundancy protocol (VRRP). It allows organizations to deploy multiple Untangle servers as hot or cold backups, and in the event of a system failure, one of the backup servers will take over. Network users will continue to have uninterrupted access to the Internet, minimizing the impact of an outage.
