NetScaler Application Firewall™ protects Web applications from the growing number of application-layer attacks and prevents the loss of valuable corporate and customer data. In addition to proven attack defenses, the NetScaler Application Firewall aids in compliance with information security regulations, such as PCI-DSS.

Fastest Web App Firewall Available
Application Firewall delivers the industry’s highest performing Web application security solution, capable of protecting Web servers without degrading throughput or application response times. The NetScaler Application Firewall delivers multi-gigabit security performance that meets the needs of any enterprise or datacenter installation.

Positive Security Model
The Application Firewall implements a positive security model to block all application-layer attacks without requiring signatures. Web application behavior deviating from the positive security model is treated as potentially malicious and blocked.By understanding good application behavior, the positive security model is the only proven approach delivering protection against zero-day attacks.

Automatic Learning Engine
In addition to delivering out-of-the-box protection against all web-based threats, Application Firewall provides the ability to tailor security policies for any application, including those using client-side javascript. Citrix NetScaler’s Learning Engine can automatically learn the behavior of an application and generate human-readable policy recommendations. The security manager can then selectively apply recommendations to strengthen a security policy and to enable permissible application behavior.
