Over the last decade, the modern data center has changed dramatically, raising a host of new security challenges. Having evolved into dynamic, complex environments with exceptionally high traffic rates, the typical enterprise data center has become increasingly hard to protect against advanced threats and malicious attacks from the outside. And while the number of external threats measure in the millions, attackers only need to succeed once to cause significant damage and loss. Simply put, there is a significant disconnect that exists between the tools we have to protect the data center, and the advancing rate of sophistication in terms of the threats we are facing. As such, a fundamentally new approach for securing the data center is required.
