Proxies function as a method to facilitate or manage complex requests and supports a more layer of security, privacy, and structure to encapsulation. Proxy servers have the potential to cover the true integrity of the requester from the recourse server.

Hardware proxies lie between the network and the internet from where they get, assess, send, and forward requests. Software proxies influence to be accommodated by a provider or exist in the cloud.
