Network Critical was established in 1997 by Alastair Hartrup to fulfil a market need for a better way to access network data traffic. Today, Network Critical is the leader in Access Technology Solutions, with award-winning, innovative products designed for the compliance era.

A global company, Network Critical leads the network monitoring industry with constant innovation and unique modular design. Our technology ensures 100% continuous network visibility and ZERO packet loss. Our products eliminate any concerns of downtime while adapting to the configuration of your network and scaling alongside growth.

Network visibility control

As the leading Access Technology Solutions provider, Network Critical is the only company bringing network access to the enterprise level. Conventional tapping is no longer a practical way to manage complex network systems. Network Critical pioneered true modular design by introducing the first modular chassis system to the market and offers smarter ways to access network infrastructures through dedicated chassis & module-based systems with features that support today’s many different monitoring needs. Only by ensuring 100% network visibility can IT leaders and practitioners deliver next-generation availability. By integrating flexibility into an enterprise-based system, Network Critical’s solutions offer the best of both worlds: reliability with the ability to make changes easily and economically.

Network Critical provides a broad range of network packet broker (NPB) solutions, a radical new approach that provides granular visibility into network activity. Network packet broker technologies intelligently direct the right traffic to the relevant network tools helping to optimise performance, compliance and deliver improved security insights. The result is vastly improved visibility right across the network. And for the ultimate in flexibility, our solutions are modular and scale to dynamically accommodate growth. This creates a highly efficient monitoring access environment that’s perfectly attuned to next-generation data demands whilst increasing ROI and reducing CapEx.

The complete line of Access Technology Solutions offered by Network Critical differs from traditional tapping technologies. Because the 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 network downtime while ensuring the network is fully compliant. The result is that all traffic is seen without affecting the flow of traffic along the live network.

From strength to strength

Having grown from a small start-up company to a successful organisation in only a few years, the company expanded in 2005, opening a second office in Buffalo, NY to handle all sales and operations for the United States, Canada, Mexico and South America. In 2007, the company continued to grow by adding another office in Amsterdam, the Netherlands, which services Eastern Europe and Asia. The basis for this rapid growth has been the company’s strength as a channel-driven company. By building partnerships with companies that offer complementary products, Network Critical is able to service the global market efficiently.

Network Critical is extremely committed to educating the information technology market about the fundamental need for accurate and reliable network traffic access. By travelling and speaking with global leaders as well as publishing articles about the subject, executives from Network Critical are spreading the word about the importance of using carrier grade technologies to access network information. Today, in the compliance era, it’s imperative that all information is easily accessible and accurately collected. With Network Critical’s products, a company can feel at ease that all its network’s accessing needs are supported.
