Elfiq Networks is recognized for its innovative and refreshing approach link balancing. Through extensive research and development, a better method of balancing has been conceived enabling a true inline business continuity appliance which will keep your organization running, even if the unit loses power. That is what we like to call "Building Smarter Networks".

This approach based on handling link management at Layer-2 of the OSI model combined with Elfiq’s exclusive feature set enables benefits for any organization requiring management of multiple telecommunications circuits. Through this integration the Primary Link concept was developed to bring integration into existing networks into a new level of simplicity and efficiency.


Benefits of this approach include

  • Lowest implementation costs: the Elfiq Link Balancer does not require changes to the gateway infrastructure to operate such as firewall reconfiguration or adjustment to the firewall rules offering a simpler and safer implementation.
  • Lightning-fast throughput: with the Layer-2 approach, the Elfiq products deliver wire-speed performance, enabling organizations to fully utilize the bandwidth they implemented.
  • Maximum equipment uptime: Elfiq Link Balancers are the only products offering both high-availability (failover) and LAN Failsafe technology. LAN Failsafe enables the Elfiq Link Balancer to bridge the primary ISP link with the firewall or other gateway should it lose power, preventing communication losses due to equipment and electric issues.
  • Maximum uptime: Elfiq Networks' Link Balancer is the only product which does not require customers to migrate DNS zone management when using local DNS servers onto the link balancer, preventing costly modifications and preventing additional points of failure.
  • ISP Flexibility: Elfiq Link Balancers can handle any type of ISP link such as T1, E2, DS3, cable modem, DSL, fiber, point to point wireless, WiMAX, 3G mobile links, satellites and much more. Private links such as MPLS, LAN extensions, private fiber and other can also be used with the Elfiq products.
