Features and Benefits
-
BENEFIT
FEATURE
Lower TCO - TCP offload, buffering and session reuse to remove repetitive network and compute processing from the servers
- SSL offload to offload expensive SSL processing from servers
- In-memory content caching to store static and dynamic content, freeing servers from repeatedly generating the same content over and over
- Multi-level content compression to reduce content on the wire by up to five times, minimizing bandwidth consumption and data congestion
Application acceleration - TCP optimizations to accelerate the performance of all TCP communications, especially over high-latency or highly congested network links
- Multi-level content compression to reduce data prior to transmission to users, reducing the amount of data traversing the network and the number of network round trips
- In-memory content caching to instantaneously serve frequently requested static and dynamic content
Application security - Citrix Application Firewall to protect HTML and XML web applications and services from both known and unknown application layer attacks
- L4 DoS protection to help ensure applications stay up even in the face of highly sophisticated network-layer denial-of-service attacks
- L7 DoS protection to help ensure applications stay up even in the face of highly sophisticated application-layer denial-of-service attacks
- Content filtering and rewrite to improve security and simplify change management by controlling access, redirecting users and changing or obfuscating application responses
Application availability - L4 load balancing featuring comprehensive health checks, session persistence mechanisms and load balancing algorithms to ensure traffic is always sent to the most appropriate server
- L7 content switching on any TCP header or payload value to direct traffic based upon application-level information, enabling further optimization of back-end resources
- Global Server Load Balancing to enhance disaster recovery by transparently redirecting users to alternate data centers in the event of an outage or interruption
- AppExpert rate controls to granularly dedicate resources to users, user groups, and specific applications by triggering NetScaler policies based either upon load from a requestor or to an application resource
All-in-one virtual appliance - Virtual appliance supports VMware ESX/ESXi, Citrix XenServer and Microsoft Hyper-V
- AppExpert Visual Policy Builder to keep policy development simple and policies supportable by eliminating complex scripts or programs from all NetScaler policies
- AppExpert service callouts for integrating logic in external applications within NetScaler policies, making NetScaler polices extremely extensible
- AppExpert templates to encapsulate the entire NetScaler configuration necessary for today's complex web applications, simplifying initial rollout and streamlining management
- Role-based administration to granularly segment administrative privilege
- Configuration wizards for simplifying the setup of load balancing, GSLB, and using NetScaler for XenApp, XenDesktop and other key applications
