The Citrix® NetScaler® family offers a rich set of features ensuring fast, secure web app delivery that you can count on:
Intelligent Server Load Balancing and Content Switching — Citrix NetScaler provides the industry’s most comprehensive Layer 4-7 traffic management. Deployed in front of application servers, 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 or TCP request’s body, as well as L4-7 header information such as URL, application data type or cookie.
Application Acceleration — Citrix NetScaler accelerates web application performance by up to five times by leveraging multiple acceleration technologies and innovative TCP optimizations. AppCompress and AppCache deliver highly efficient data compression and caching of static and dynamic content to speed application responses. NetScaler TCP optimizations offers network management solutions that overcome the issues caused by high latency and congested network links and are transparent to clients and servers. This is done by accelerating the application 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.
SSL Acceleration — NetScaler integrates hardware-based SSL acceleration to offload the compute-intensive processes of SSL connection setup and bulk encryption from Web servers. SSL acceleration reduces CPU utilization on servers, freeing server resources for other tasks. SSL acceleration is automatically enhanced by TCP optimizations and is fully integrated with the AppCompress option.
Web Application Firewall — Citrix Application Firewall offers web application security from the growing number of application-layer attacks, including buffer overflow exploits, SQL injection attempts, cross-site scripting attacks and more. In addition to proven attack defenses, the NetScaler Application Firewall module provides identity theft protection by securing confidential corporate information and sensitive customer data.
Global Server Load Balancing — Global Server Load Balancing delivers global traffic management for multi-site enterprises and service providers as a comprehensive solution for global load balancing and disaster recovery.
Access Gateway Enterprise Edition -– NetScaler integrates the complete SSL VPN functionality of Citrix Access Gateway™, Enterprise Edition and Citrix SmartAccess. With Access Gateway users have easy-to use, secure access to the applications they need to be productive. And you have peace of mind, knowing the SmartAccess technology in Access Gateway ensures only authorized users have access to critical business resources.
Powerful Policy Engine and Intuitive Management Capabilities — 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 managed with either a Web-based graphical user interface (GUI) or a powerful command-line interface (CLI).
