Proxy is a system or router that provides a gateway between users and the internet. It helps prevent cyber attackers from entering a private network¹. It is referred to as an “intermediary” because it goes between end-users and the web pages they visit online.
Proxy servers provide a valuable layer of security for your computer. They can be set up as web filters or firewalls, protecting your computer from internet threats like malware. This extra security is also valuable when coupled with a secure web gateway or other email security products.
