Positive Security Model

Citrix Application Firewall's security technology implements a positive security model based on HTTP industry standards and best coding practices for HTML. 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 does not require attack signatures or pattern matching techniques to detect and block attacks. It is the only proven approach delivering zero day protection against unpublished exploits.

Adaptive Learning Engine

Citrix's third generation Adaptive Learning Engine can automatically learn the behavior of an application and generate human‑readable policy recommendations.
