What is web proxy authentication?

Web proxy authentication is a security mechanism that requires users to verify their identity before accessing the internet through a proxy server. It helps organizations control and monitor web traffic by restricting access based on user credentials, IP addresses, or authentication tokens.

This ensures that only authorized users can use the proxy, enhancing security, preventing unauthorized access, and enabling compliance with network policies. Common authentication methods include basic authentication (username and password), NTLM, Kerberos, and OAuth, depending on the level of security required.
