Foxy: Filtering Proxy

Foxy is a filtering web proxy.

It acts as a middleman between the users browsers and the Internet.

All through traffic is inspected, categorized, counted, and may be

modified, redirected, or blocked, if neccessary.

Foxy is not just another “internet filter           ”,

“popup blocker 
  
 
  
 
  
 
  
 
  
 
 ”,

“porn stopper











”,

“form filler 
  
  
  
  
  ”,

etc.

It can do it all, and much, much more.

Blocks popups, banners, cookies, scripts, applets, objects, various media types,

deanimates GIF images, spoofs request headers

Foxy has all the features common to web filtering software

but it goes the extra mile.

For example, its easy to block JavaScript, but it

completely breaks many sites that use scripts in all their links.

Unlike other web filters, in many cases Foxy can convert

scripted links to regular links when blocking JavaScript, which

preserves functionality of many de-scripted web sites.

Protects your kids from porn

Foxy analyzes web pages on the fly consulting user-defined

dictionaries and blocks access to sites containing objectionable

content.

Thousands of new sites appear every day. Most commercial

blockers rely on static domain lists. The user has to pay for

subscription to keep up with the constantly changing Internet.

Vendors usually claim that domain lists are “manually

categorized 
  
  
  
  
  
 ”, etc. Actually, domain databases are

produced by automated crawlers configured with categorized

dictionaries.

Foxy does it on the fly. All known and yet unknown sources

of objectionable content can be easily blocked. Its up to

the user to decide what kind of content should be blocked

and how sensitive the matching should be. For more details

please see filter documentation.

Static categorization by domain list is also available.

May be used, for example, to prevent your employees from

accessing the web anonymosly via public CGI proxies.

Efficiently blocks server-side spyware

Server-side spyware (a.k.a. “web analytics technologies

 


 


 


 


 


”)

is the nastiest thing on the web.

Its invisible, but it can track your steps across

multiple sites and easily gets past firewalls,

cookie blocking, etc. Almost every commercial web site uses

this technology today. E.g. open page source of cnn.com,

mapquest.com, or almost anything else and look for something like

SiteCatalyst, RedSheriff, WebSideStory, Nielsen//NetRatings,

Vibrant Media, Google Analytics, or Tacoda.

Foxy recognizes malicious code fragments from those sources embedded

in host pages by unique signatures and deletes them on the fly.
