SonicWALL NetFlow support was introduced in SonicOS 5.8. Some benefits include network planning and monitoring, application and user monitoring, security analysis and more. Read more »

Palo Alto Networks NetFlow support is coming soon and we’ll be one of the first vendors to support it in our NetFlow Analyzer.  The team at Palo Alto Networks not only supports traditional NetFlow, but they also support deep packet analysis to identify actual applications such as Skype, BitTorrent, Webex and more.  Many netflow analysis tools mistakenly identify this traffic as HTTP (TCP 80).  Cisco NetFlow NBAR is a similar technology which makes network traffic monitoring much more informative especially when trying to perform root cause analysis. This feature is not in the Cisco ASA NetFlow export.
