Proxy Authentication: Definition
Proxy authentication is the method a provider uses to verify that a customer is allowed to route traffic through its proxies. The two common approaches are username-and-password credentials and IP allowlisting, where a customer's own address is pre-approved. Authentication prevents unauthorized use of purchased proxy resources.
Related terms: Allowlist, Ip Address, Endpoint, Backconnect Proxy.
