The SmartNA-XL chassis offers four 1/10G slots to integrate a wide variety of Passive, Active or Bypass TAP modules that safely connect tools while protecting network reliability and availability. In addition, a rear slot for a another 1/10G module that allows connection to high speed optical networks or tool farms, and stacking of SmartNA-XL units for scalability.

Advanced features such as aggregation, filtering, load balancing and port mapping reduce planning, configuration and tool management time. Information is the lifeblood of modern business. Network Critical’s SmartNA-XL enables organizations to manage the flow of information securely, efficiently and reliably.



Aggregate SPAN/TAP traffic feeds across multiple network links, filtering, optimizing and feeding the combined traffic to connected security and monitoring tools for further analysis

Identify traffic based on signature or patterns across any part of the packet - or corresponding to application sessions - and forward to security appliances, increasing their efficacy and performance.


Distribute traffic among multiple ports based on a variety of options: hashing, bandwidth, cumulative traffic, packet rate, connections, and more.

“Continuous monitoring is critical to digitization and automation of our many monitoring systems. Being able to monitor remote sites from a single location keeps our systems up to date without having a large staff running around in trucks.”


Senior Project Manager, Refining Operations


“In addition to monitoring control systems, we have security tools that understand our traffic patterns and look for anomalies that might signal malware or viruses attempting to embed in our systems. Unauthorized manipulation of our monitoring systems can have serious safety and production consequences. Network Critical TAP’s help us manage security without impacting network traffic.”
