ACCELERATED APPLICATION PERFORMANCE
Citrix NetScaler accelerates web application performance by up to five times by leveraging multiple acceleration technologies and innovative TCP optimizations. Citrix® AppCompress™ and Citrix® AppCache® deliver highly efficient data compression and caching of static and dynamic content to speed application responses. NetScaler TCP optimizations overcome the issues caused by high latency and congested network links and are transparent to clients and servers, accelerating the delivery of any enterprise or web-based application while requiring little or no configuration. Real-time and historical page-level monitoring of end-user performance experience is provided by Citrix EdgeSight® for NetScaler.

COMPREHENSIVE APPLICATION SECURITY
NetScaler protects web applications from application-layer attacks, helping to prevent the theft and leakage of valuable corporate and customer data. Patented Citrix® Request Switching® enables NetScaler to proxy legitimate client requests and block illegitimate requests, and includes high-performance, built-in defenses against denial of service (DoS) attacks. Legitimate surges in application traffic that would otherwise overwhelm application servers are automatically handled with configurable Surge Protection and Priority Queuing features.

INCREASED APPLICATION AVAILABILITY
To help ensure application availability, NetScaler delivers fine-grained direction of client requests to ensure optimal distribution of traffic. In addition to Layer 4 information (protocol and port number), traffic management policies for TCP applications can be based upon any application-layer content. Administrators can granularly segment application traffic based upon information contained within an HTTP request body or TCP payload, as well as L4-7 header information such as URL, application data type or cookie. Numerous load-balancing algorithms and extensive server health checks provide greater application availability by ensuring client requests are directed only to correctly behaving servers.

REDUCED DEPLOYMENT AND OPERATING COSTS
Citrix NetScaler cuts application delivery costs by reducing the number of required servers and by optimizing usage of available network bandwidth. The intuitive AppExpert Visual Policy Builder enables application delivery policies to be created without the need for coding complex programs or scripts. In addition, NetScaler reduces ongoing operational expenses by consolidating multiple capabilities in a single solution. For managing multiple NetScaler appliances, the separately available NetScaler Command Center provides centralized administration of system configuration, event management, performance management and SSL certificate administration.

Citrix NetScaler is available in three different software editions and four different appliance platforms, providing choice of application functionality and required system scalability.

Citrix NetScaler Platinum Edition provides a web application delivery solution that reduces data center costs and accelerates application performance, while providing end-to-end visibility of application performance and advanced application security.

Citrix NetScaler Enterprise Edition provides web application acceleration and advanced L4-7 traffic management, enabling enterprises to increase Web application performance and availability and reduce data center costs.

Citrix NetScaler Standard Edition provides small and medium enterprises comprehensive L4-7 traffic management, enabling increased web application availability.
