Description
Network traffic can be "tapped" from the outside. For example, you can find out how many computers are surfing the internet, and where to. This may provide a potential attacker with important information for a future attack. In addition, several users may often visit the same page, maybe even one that has a lot of content with big files. This is yet another aspect that can be improved with a proxy server.

Customer Benefit
In a company with internet access, the proxy server is always linked with a gateway server or a firewall connecting the corporate network to the internet. The proxy server plays the part of a go-between, for example between a user's workstation and the server on the internet. This setup provides the company with additional security: from the outside, a potential hacker can only see that a single computer, that is, the proxy server, is accessing the internet. For the user, on the other hand, the proxy is invisible. Plus, a proxy server makes it easier to administer and control internet access. It also has a caching function which allows you to cache the content of a frequently visited homepage.

Scope of Services
It goes without saying that an existing firewall with proxy functionalities will be used to your advantage. Often, however, the capacity of these firewalls is not sufficient to handle more complex applications, especially for HTTP protocols. For that reason, we prefer to use the following open source products as proxy software for HTTP protocols:
Squid Web Proxy Cache - An HTTP proxy that for a certain period caches the transferred data according to different criteria. If the same data is requested again, it only provides the locally cached data, leading in many cases to less bandwidth usage and reducing the response times experienced by users.
