Your IT environment has evolved significantly over the past decade, expanding from a centralized data center approach to a more cloud and mobile-centric model. Attackers have adjusted their tactics along the way, shifting their focus from servers in your data center to your users and web browsers, and developing cyber-attacks that elude traditional signature-based security methods Unfortunately, enterprises have largely failed to keep pace with these changes, continuing to use dated methods to thwart attacks, and appliance-based security infrastructure to protect an increasingly cloud and mobile centric workplace. As a result, despite costly on-premise internet security solutions, many enterprises find vulnerabilities in their current infrastructure.
