Howdy, y’all, and welcome to The Cyber Ranch Podcast!  That’s Jon Green, an experienced CISO but also an experienced CTO.  Jon is currently the CSO and CTO at HPE’s Aruba.  He’s also a DefCon goon and a Team8 Villager.  He’s done the marketing engineer side, the network engineer side…  Quite a storied past.  We are thrilled to be talking with him about the differences between CSO/CISO and CTO.  Jon, thank you so much for joining us at the ‘Ranch! Tell us about your early career, did you start in security or as a technologist? What are the key priorities for someone with a CTO title?  As someone who has held both CTO and CSO titles, how does the pressure to deliver revenue impacting products differ from the pressure cyber leaders face? What does it feel like to be on the receiving end of security requirements which are often developed in the abstract or for the general case? When you are assessing future trends and technology shifts, what are the different lenses you use to make the security evaluation vs the more functional and integration-oriented evaluation? What is something you have learned which surprised you?  What do you wish other CSOs understood better?  What is a piece of advice… You’ve been involved in Defcon and other cyber events for many years, what changes have you seen during that time? Y'all be good now!
