"I agree with Gartner on this. Our enterprise has been using Cisco FW for over 10 years, we have been moving to Palo Alto (replacing Cisco) over the past two years, as fast as possible. There is no comparison between the two. In my opinion, Cisco stopped innovating in Security a long time ago and there current story of bolting on a smart blade to a 15 year old stateful FW didn't cut it for us (previous experineces with this approach was not good). Cisco lost our IPS business years ago for the same reason. lack of innovation and effectiveness."
