Key Features & Benefits


Offload compute-intensive SSL transactions from the server, preserving resources for applications. In addition, optimisation features such as caching, compression, and TCP pooling enable faster application delivery and ensure scalability.


Using health and performance checks, the ADC distributes traffic for efficient use of server resources and employs server failover for high availability. Global Server Load Balancing allows redundancy across multiple sites enhancing availability and speeding disaster recovery.


Content routing and content rewrites enable full control of application traffic and customised application delivery based on users, regions, and/or devices. Client controls gives administrators the ability to throttle requests to ensure application availability even during periods of heavy traffic.


Integrates Active Directory or any other RADIUS or LDAP-compatible authentication services. Combined with the strong access control capabilities, administrators can provide granular control over user/group access to resources. This ensures that only authorised users will be able to reach applications.


Industry-leading security helps organisations secure critical applications. Protecting against OWASP Top 10 attacks such as SQL Injection, Cross-site Scripting (XSS), and Cross-site Request Forgery (CSRF). Granular controls over the number of requests helps protect against rate-based attacks like DoS or DDoS. 


Our Load Balancing ADC technology also provides outbound content inspection for Data Loss Prevention (DLP). It prevents data leakage by either masking or blocking responses containing sensitive information such as credit card numbers or any other custom data patterns.
