What is a proxy server?

Anonymous proxies are servers that conceal the client’s IP address, allowing access to resources blocked by firewalls or IP address bans. They could be utilized to increase privacy or as a defense against cyber attacks. This added security is also beneficial when used with a secure web gateway or other email security tools. You can factor in the amount of traffic that a network or specific computers can handle, its level of safety, or both when filtering traffic in this way.

The proxy server exists in a physical data center, and the user’s requests are routed through how does a proxy work that server. A proxy server is a system or router that provides a gateway between users and the internet. Therefore, it helps prevent cyber attackers from entering a private network.
