Network analyzers (also known as sniffers) are hardware or software applications that can intercept, inspect and collect data traffic passing along a network for further analysis. These types of devices are used to analyze network problems, detect intrusion attempts, monitor network usage, gather and report network statistics and many other applications.

Why do you need to use an Access Technology Solution with your Network Analyzer?
Gaining access to 100% of network traffic is essential for successful network analysis. SPAN ports may not provide 100% of network traffic if they are over-subscribed or they may not be available for use when necessary. It may also be necessary to monitor multiple network segments simultaneously and aggregate the data to your network analysis tools or to replicate the data to more than one network tool at the same time.
Network Critical Solutions for Network Analyzers
The problems associated with installing a network analysis tool can all be solved by implementing a Network Critical Access Solution into your network infrastructure. Breakout TAPs provide easy single segment monitoring while the Aggregating and Regenerating TAPs allow for the combination for different network segments as well as the ability to copy your data traffic to several network tools at the same time. The Smart Network Access System allows you the ability to do all of these things in a high density environment and the flexibility to adjust to the changing needs of your datacenter.
