Application Delivery and Security at Enterprise Scale

NetScaler has spent two decades in front of the world's most demanding applications, and today operates as an application delivery and security business of Cloud Software Group. The platform combines load balancing, traffic management, SSL/TLS offloading, and dynamic scaling with a security layer that includes a web application firewall, API protection, bot mitigation, and zero trust network access.

Its defining architectural claim is consistency: one codebase across every form factor — hardware appliances, virtual machines, containers, and bare metal — so applications behave the same whether they run on-premises, in the cloud, or in hybrid environments.

NetScaler serves large enterprises, including more than 90 percent of the Fortune 500, where application availability, performance, and layered application security have to hold up at global scale.
