The Citrix ADC product line optimizes application delivery over the Internet and private networks. The ADC solution is an Application Delivery Controller that accelerates application performance, increases their availability through advanced L4-7 load balancing, protects mission-critical applications from attacks, and reduces server costs by offloading computationally demanding tasks. All these capabilities are combined in a single, integrated device to increase performance while reducing total cost of ownership.
In environments where application performance directly translates to user experience and business results, Citrix ADC plays a critical role. Every millisecond of delay in e-commerce page loading can mean lost conversions. Every transaction system downtime generates financial and reputational losses. ADC minimizes these risks through intelligent network traffic management.
Citrix ADC is deployed in front of web, application, and database servers. It combines fast L4-7 load balancing and content switching with application acceleration, data compression, static and dynamic content caching, SSL acceleration, network optimization, application performance monitoring, and robust application security through a web application firewall (WAF).
Layer 7 load balancing enables traffic routing based on HTTP request content – headers, cookies, or URL parameters. This allows directing different user types to dedicated servers, A/B testing, or rolling deployments without service interruption.
The built-in Web Application Firewall (WAF) protects against OWASP Top 10 attacks, including SQL injection, cross-site scripting (XSS), and session attacks. Application-level DDoS protection complements network security, blocking attacks exploiting HTTP protocols.
Citrix ADC is available as a hardware appliance, virtual machine, and cloud service, enabling consistent application delivery policies across hybrid and multi-cloud environments.
