About Us

Established in 1997, Network Critical is a United Kingdom based company with global reach providing traffic visibility for enterprise, carrier and government networks. Our products allow organizations to safely connect monitoring, security and performance tools.


The complete line of visibility solutions offered by Network Critical is different from traditional tapping technologies. Our products make a copy of a network’s traffic, they isolate themselves from the live network and are able to collect all traffic passing through the network without introducing latency. This reduces the risk of network downtime, while ensuring the network is fully visible. The result is that all traffic is seen without impacting the flow of traffic along the live network.

Our Vision

The engineers and developers at Network Critical continue to work on their vision of network visibility for the future. New network architectures and infrastructures such as Network Function Virtualization (NFV), Software Defined Networks (SDN) and others will require new visibility strategies and technologies. As carriers prepare for the 4G to 5G transition and enterprise networks wrestle with BYOD, information security and far flung cloud architectures, Network Critical will be there with visibility solutions. We are committed to continuing our legacy of providing innovative, reliable and cost effective visibility solutions for networks today and into the future.
