In my opinion, the best features Squid Proxy Cache Server offers are that it is open-source, well-known, well-documented, has great performance, and has many plugins and features embedded, including the security capabilities. You can limit traffic, reduce traffic, scan traffic, and create whitelisting of websites or blacklisting of websites, such as mature content or whatever is not allowed in your company or project needs. Additionally, there are different models to authenticate through Squid Proxy Cache Server with a database and create solutions bound to the username. You can actually grant access for a specific user by their specific credentials. Squid Proxy Cache Server has positively impacted my organization by reducing the cost of internet providing traffic, speeding up the connection, and speeding up the loading for the developers. For another project, one of the products was built on Squid Proxy Cache Server fully. Traffic was reduced by approximately thirty to forty percent when comparing caching and without caching through Squid Proxy Cache Server, so it dramatically reduced the cost.
