Re: netflow in the core used for surveillance

Hi, all. Re: last week's thread on the Vice article - I can only speak for Kentik, and *we* don't resell or give 3rd party access to NetFlow data from our hundreds of customers. And never have. But there is definitely interest out there. We do get approached about it periodically and always

Re: netflow in the core used for surveillance
