Watch how F5 customers can now simply use BIG-IP APM to consolidate access control in a central location, keeping infrastructure administration concerns to a minimum. With BIG-IP solutions, customers enjoy the flexibility and scalability needed to extend Citrix applications to both local and remote users without changing local XenApp deployments or requiring STA to provide secure remote access to applications. In a local Citrix XenApp environment where traditional client devices connect directly to the LAN, Citrix Web Interface servers handle user authentication and authorization. Adding remote users and mobile devices would typically require reconfiguring existing Web Interface servers, or adding and administering additional Web Interface instances to handle remote access. In either case, customers would need to deploy a Citrix Access Gateway solution and manage the Citrix Secure Ticket Authority (STA) service to provide authentication and grant user access.
