In reply to Frank D'Agostino.

Thank you for this post. I will be very happy to host you in Africa Frank and of course we are already working closely with our customers in Africa to help them address their real word DC security problems. Segmentation is a great start for good security but unfortunately not a complete strategy, it will be reckless for any information security professional to claim otherwise.
I am very glad there are customers using micro segmentation strategies in their virtualized data centers, this will help them to understand the value but also the limitations of a virtual segmentation only approach to security and sooner or later will realize that a wholistic strategy including purpose built hardware is indeed beneficial and also required to enable business while protecting against todays threat landscape.
