Proxy Firewalls
A proxy firewall serves as an intermediate device between internal and external systems communicating over the Internet. It protects a network by forwarding requests from the original client and masking it as its own. Proxy means to serve as a substitute and, accordingly, that is the role it plays. It substitutes for the client that is sending the request.

When a client sends a request to access a web page, the message is intersected by the proxy server. The proxy forwards the message to the web server, pretending to be the client. Doing so hides the client’s identification and geolocation, protecting it from any restrictions and potential attacks. The web server then responds and gives the proxy the requested information, which is passed on to the client.

| Advantages | Disadvantages | Protection Level | Who is it for: |
| – Protect systems by preventing contact with other networks.– Ensure user anonymity.
– Unlock geolocational restrictions. |
– May reduce performance.– Need additional configuration to ensure overall encryption.
– Not compatible with all network protocols. |
– Offer good network protection if configured well. | – Used for web applications to secure the server from malicious users.– Utilized by users to ensure network anonymity and for bypassing online restrictions. |
