Hello I have some sites that I monitor with this wonderful product, and I wanted to know since I will be back hauling data from my various sites back to my network, will this data be encrypted? I don't want to move these data packets and or Netflow Security Event Loggs over the internet un encrypted. Is there a way to fix this or is there something that I am missing?

Only Flexible Netflow allows netflow traffic that originates at the router to be encrypted over a IPSec VPN, normal Netflow traffic cannot be encrypted. What you could do is set up a remote probe in the same network segment as the router and have the router send the flows directly to that remote probe internally without sending the information over the internet. The traffic between our Core and the Remote Probes is encrypted so that shouldn't be a worry.

Thank you, taking into account that I will be dealing solely with Cisco ASA 5500 series Firewalls, I will only be dealing with "Netflow Security Event Logging". That being said I found another post on your Knowledge Base that Directly ties into this.
