Palo URL Filtering for PA-500 for High Availability - subscription license renewal (1 year) - 1 device in HA pair

Stand-alone URL filtering solution is insufficient control mechanisms because it is easily bypassed with external proxies (PHproxy, CGIproxy), circumventors (Tor, UltraSurf, Hamachi) and remote desktop access tools (GoToMyPC, RDP, SSH). Controlling users' application activity requires a multi-faceted approach that implements policies to control web activity and the applications that are commonly used to bypass traditional security mechanisms.

Palo Alto networks firewalls identify and control applications, irrespective of port, protocol, encryption (SSL or SSH) or evasive characteristic. Once identified, the application identity, not the port or protocol, becomes the basis of all security policies, resulting in the restoration of application control. Acting as the perfect complement to policy-based application control is a URL filtering database that securely enables web usage. By addressing the lack of visibility and control from both the application and website perspective, organizations are safeguarded from a full spectrum of legal, regulatory, productivity and resource utilization risks.
