Deepnines Proxy Blocker Detect And Eliminate Security Bypass

DeepNines Proxy Blocker detects and eliminates Web-based proxies that circumvent network security and filtering solutions: By identifying; reporting and preventing Web proxies in real-time; Proxy Blocker protects against users bypassing content filtering; security policies and malware detection across all ports and protocols: By preventing unauthorized access to the Web; users cannot access online content and applications using the over 200 ports and the variety of protocols that consume bandwidth; violate security policies; and open vulnerabilities in the network.

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:

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.

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 can be used as a proxy by either choosing the option to translate 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 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.
