Web Proxy Caching & Compressing

CacheGuard Web Gateway appliance embeds a Web proxy.

CacheGuard Web ProxyWeb Proxy - CacheGuard Proxy

Whenever you directly connect your personal computers or other connected devices to the Web, you expose yourself to severe threats that can terribly harm your activities. CacheGuard Web proxy acts as an intermediary facility between your connected devices and the Web and allows you to don’t expose your vulnerable devices to the Web.

CacheGuard Web proxy can be implemented transparently in your networks without the need to configure your connected devices to use it as a proxy. As soon as CacheGuard is placed in the path of passing Web traffic, it can transparently intercept Web traffic and play its role as a Web proxy.

With CacheGuard you navigate the Web safely and smoothly.

Active Web Proxy

CacheGuard not only acts as an intermediary between connected devices and the Web but it has also the capability to do it actively by filtering, caching, compressing and shaping the Web traffic in order to deliver secure and optimized Web traffic. 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.

Compared to a Web cache on a personal computer which is only accessible by an individual, the caching feature of CacheGuard is particularly interesting because it allows you to share the same cache among all connected devices. 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.

Associated with an LDAP or AD server, CacheGuard also allows you to authenticate users in order to grant or deny their access to the Web. The Authentication feature of CacheGuard coupled with its URL filtering feature make it possible to build sophisticated URL filtering and access management policies.

See the Gateway Antivirus and URL Filtering pages for further information on how CacheGuard can filter the Web traffic content.

Powered by Squid

CacheGuard Web proxy is based on Squid which is the most famous Open Source proxy cache used around the globe. This proxy supports HTTP, HTTPS and FTP at the server side while clients connect using HTTP and HTTPS. 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 develop your Web Gateway yourself. Otherwise you can use an Off-the-Shelf solution like CacheGuard.

At CacheGuard Technologies Ltd. we have more than 15 years of experiences with Open Source technologies like Squid. We spent more than 25.000 hours to design and develop our solutions in order to allow you to build your own Web Gateway in 15 minutes. Our solutions are highly integrated and allow you to concentrate on your core business while we deal with all issues around complex technologies on which CacheGuard is based on.
