Not only are web applications vulnerable to attack, they are attractive targets for hackers because they often have direct connectivity with one or more databases containing sensitive customer and company information. Protecting these applications with solutions that simply inspect application traffic to identify known attack signatures is insufficient. Threats against web applications are often devised specifically for a target application, making threat identification by network-level security devices (e.g., intrusion protection systems and network firewalls) impossible—leaving web applications exposed to a myriad of known and zero-day exploits. NetScaler Application Firewall comprehensively addresses the challenge of delivering centralized application- layer security for all web applications and web services.

Citrix NetScaler Application Firewall is a comprehensive ICSA certified web application security solution that blocks known and unknown attacks against web and web services applications. NetScaler Application Firewall enforces a positive security model that permits only correct application behavior, without relying on attack signatures. It analyzes all bi-directional traffic, including SSL-encrypted communication, to protect against a broad range of security threats without any modification to applications. It is also a leading ADC solution capable of providing over 12 Gbps of application security throughput to meet the needs of even the largest networks today.
