CacheGuard Web Gateway Appliance embeds a Web Proxy.

CacheGuard forwarding Web ProxyWeb Proxy - CacheGuard Proxy

Because your PC or any other devices that you regularly use to connect to the Web are vulnerable, you expose yourself to severe threats whenever you directly connect to the Web. But there is no need to panic if you implement a Web proxy. CacheGuard Web Proxy acts as an intermediary facility between you the Web and hence addresses threats when you connect to the Web.

CacheGuard Forwarding Proxy can be implemented transparently in your networks without the need to configure your connected devices to use it as a Web proxy. As soon as CacheGuard Forwarding Proxy is placed on the path to the Web, it transparently intercepts Web traffic and play its role as a Web proxy. In this way, users navigate safely the Web without having to worry about connectivity issues.

CacheGuard Web Gateway is not just a Forwarding Proxy but it is a Firewall, a Gateway Antivirus, a Reverse Proxy, a WAF, a URL Guard, a Traffic Shaper, a Web Cache, a Web Compressor, an SSL Mediator/Inspector and much more.

Active Web Proxy

CacheGuard Forwarding Proxy does not act just as a passive intermediary between connected devices and the Web but it has also the capability to actively process the Web traffic by filtering, caching, compressing and shaping the Web traffic in order to deliver Secure and Optimized Web traffic to users. With the caching and compressing you can save your network bandwidth usage while the filtering allows you to block all attempts to access malicious or unwanted contents coming from the Web even in an encrypted form.

Web Caching
Compared to the cache of a Web browser which is only accessible by an individual, the caching feature of CacheGuard Forwarding Proxy is particularly interesting because it allows you to share the same cache among all connected users. Sharing the same Web cache between multiple users allows you to save your network bandwidth by delivering cached objects to users instead of getting them from the Web.
Web Access Authentication
Associated with an LDAP or AD server, CacheGuard Forwarding Proxy allows you to authenticate users before granting them access to the Web. The association of CacheGuard Authentication and CacheGuard URL Filtering makes it possible to build sophisticated URL Filtering policies.

Powered by Squid

CacheGuard Forwarding proxy integrates the very well-known Squid proxy. It supports HTTP, HTTPS and FTP at the server side while clients connect using HTTP(S). If you are familiar with Linux (or BSD), firewalls, complex configuration files, all tools around Squid (like SquidGuard, ICAP/ECAP, and many others) and have the time and patience to configure all those tools to match your requirements in terms of capacity and performance, you can probably implement your Web Proxy using directly Squid. Otherwise you can implement CacheGuard Web Gateway in a few minutes and start securing your network straight away.
