Proxy servers play a crucial role in network security, providing strong support and protection for network security, from hiding user identities, protecting servers from attacks, to improving network browsing speed and efficiency. Its main functions are reflected in the following aspects.

Hide real IP addresses

Proxy servers can help users hide their real IP addresses, thereby protecting their privacy. When users access network resources through proxy servers, the target server cannot directly obtain the user's real IP address, reducing the risk of users being located, tracked, or attacked.

Bypass access restrictions

Some websites or services may impose access restrictions on specific IP addresses or geographic locations. By using a proxy server, users can change their exit IP address to appear to come from another region or country, thereby bypassing these restrictions and obtaining the necessary access permissions.

Preventing DDoS attacks

Distributed Denial of Service (DDoS) attacks often flood target servers with a large amount of malicious traffic. By setting up a reverse proxy server, traffic can be filtered and monitored on the proxy server, thereby reducing the burden on the target server and preventing malicious attacks.

Content filtering and blocking

Proxy servers can be used to filter, review, or block specific types of content, such as malware, advertisements, or malicious content. This helps to protect the internal network from malicious content and improve the network security of employees or users.

Isolate internal and external networks

A proxy server can act as an isolation layer between the internal and external networks, preventing external users from directly accessing the internal server. This helps to reduce the risk of external attackers invading and improve the security of the internal network.

Logging and auditing

The proxy server can record access logs, including user access behavior, request and response content, etc. These logs can be used for security audits to help monitor and identify potential threats or abnormal activities.
