A proxy server sits between your device and the internet, forwarding your requests and returning the responses. It can filter traffic, hide your IP, cache content, or enforce policy. See our overview for defenders for a deeper dive.
Proxies help control and protect traffic at scale - from basic privacy to content filtering and access control.
Your request goes to the proxy, not directly to the site.
The proxy applies rules, logs, or cache checks, then forwards the request.
The destination replies to the proxy, which returns data to you.
Extras can include authentication, URL filtering, and malware checks.
A proxy is not end-to-end encryption - traffic can be inspected at the proxy.
Free or unknown proxies may harvest data; choose reputable providers.
Pick a trusted provider with HTTPS support and a clear no-logs policy.
Configure per app or system-wide and test with a known site.
Require authentication and restrict who can access the proxy.
Pair with TLS or a VPN for sensitive work.
