2. Web Proxy Data Sheet
Blocking Web Proxies
The combination of proprietary signatures and deep packet inspection allows Proxy Blocker to identify and block all Web
proxies regardless of port, protocol or application to ensure network security and compliance. The chart below outlines
some of the many types of Web proxies, and how they typically work when bypassing filtering and firewall policies.
DeepNines Proxy Blocker technology eliminates all of these proxy types and more.
Type Description Blocked by
DeepNines
Anonymous Proxies Anonymous proxies are the most common type of Web proxy and therefore
easiest to block. These are generally URL-based and offer an embedded
feature that allows users to bypass the network through an interface on
the website.
Circumventors Circumventor software can be placed on a home (or any out-of-network)
computer, and it will return a URL that acts as a proxy and can be used
to connect back to that computer for anonymous browsing. These URLS
are dynamic and easily changed if ever discovered and blocked.
Tor Network The Tor network is a network of virtual tunnels that creates an indirect
connection to the Internet by having the desired connection to hop
through all of the computers on the Tor network before reaching its final
destination, therefore disguising the browsing session and circumventing
filtering policies.
Browser Proxies Browser proxies are a more complex version of anonymous proxies that
provide the option of selecting different types of encoding to further hide
the connection.
SSL Proxies SSL (or encrypted) proxies form a secure connection (HTTPS) which can
only be detected and stopped by recognizing the proxy connection before
the three-way handshake is completed and the secure tunnel is formed.
Google Proxies Google can be used as a proxy by either choosing the option to translate
Google Mobile the website into another language, or show content as it would appear on a
mobile device, both of which allow for unrestricted Web browsing that all
appears to come from Google and therefore circumvents filtering policies.
Transparent Proxies Transparent proxies work when a user changes his/her browser settings to
search through a proxy. Thousands of free IP addresses are available online
and can be easily added to any browser. These IP addresses are constantly
changing and therefore very difficult to detect and stop as thousands of
new IPs are published daily. DeepNines_WebProxy_0909
