Integrates load balancing efficiently within existing technology environments
FortiADC provides load-balancing capabilities needed for integration with other Fortinet platforms. It allows for the creation of virtual IPs and applying various algorithms for traffic management. Although it offers fewer algorithms than competing platforms like F5, its capability to manage load balancing makes it valuable. The security features depend on the environment, relying on firewalls like FortiGate.
