Cyber Security

A proxy server acts as an intermediary between the user and the internet, forwarding requests on the user's behalf and hiding the user's own address.

Web requests go to the proxy, which then fetches the pages and passes them back, so the destination server sees the proxy's address rather than the user's. A proxy can filter traffic to block access to undesirable or malicious sites, hide the user's IP address for privacy, and cache frequently requested pages to speed up access. It can also absorb some attack traffic before it reaches the real server, helping to protect against attacks such as DDoS.
