Proxy Types Explained

Proxy Types Explained

Not all proxies work the same way. Understanding the different types helps you pick the right one for your needs.

Forward vs Reverse Proxies

A forward proxy sits in front of the client. It forwards your requests outward to the internet, hiding your identity from destination servers. This is what most people mean when they say "proxy."

A reverse proxy sits in front of a web server. It receives incoming requests from the internet and distributes them to backend servers. Reverse proxies are used for load balancing, SSL termination, and caching. You interact with reverse proxies constantly without knowing it — most large websites use them.

Anonymity Levels

Proxies are also classified by how much information they reveal about you:

• Transparent proxies — Pass your real IP address in the X-Forwarded-For header. They offer no anonymity and are mainly used for caching or content filtering.
• Anonymous proxies — Identify themselves as proxies but do not reveal your real IP. Websites know you are using a proxy, but cannot trace the connection back to you.
• Elite (high-anonymity) proxies — Do not identify as proxies at all. No forwarding headers are sent. The destination server sees only the proxy's IP, with no indication a proxy is in use.

For maximum privacy, elite proxies are the clear choice. You can verify your proxy's anonymity level using our proxy checker tool.
