Team Cymru has a netflow analyzer that matches your netflow data to known 'bad IPs'. http://www.team-cymru.org/Flow-Sonar.html Thanks, Scott Thanks, Scott On 3/12/18 7:24 PM, [email protected] wrote: > Howdy! > > Checking out various Netflow tools and wanted to see what others are using? > > Kentik is cool.
