So, just to raise the bar…I had someone once tell me they encrypted everything since they
were using IPsec.  Since I only trust configurations, lo and behold the configuration was
IPsec AH.  As exercise to reader….determine why using IPsec does not automagically equate to
encrypted traffic.  

This was only 2 years ago while doing a security assessment for someone.

I greatly dislike the term 'VPN'…..always have and always will.   Marketechture is awesome!
