    -<note important>Our filtering solution helps the operator to save on development and support of a solution of his own. It has several advantages over a proxy server. Additionally, the operator gets the platform that enables him to save resources and get an income by providing new value added services.</note> 
    - 
    -Required components: 
    -  - [[en:dpi:dpi_components:platform:start|Deep Traffic Analysis Platform (DPI)]] 
    - 
    -Advantages: 
    -  - Easy to use: 
    -    - all rules are applied at one place: on DPI platform; 
    -    - the platform loads and applies rules from lists by itself. 
    -  - Productivity: 
    -    - the list includes up to 4 billion URL. Its representation in memory is compressed; 
    -    - provides filtering of up to 2 million URL per second on one CPU kernel; 
    -    - traffic capacity up to 40 Gb per second per one CPU; 
    -    - unlimited scaling by simple installation of additional servers; 
    -    - propagation delay is less than 30 μs. 
    -  - Functionality: 
    -    - http and https support. Other protocols can be added; 
    -    - filtering for HTTP proxy is supported (including Opera Turbo/Mini); 
    -    - the software can consider or ignore the port number (i.e. block http://www.example.com и http://www.example.com:8080 together or separately); 
    -    - does not depend on IP address changes; 
    -    - redirection instead of blocking is supported for http; 
    -    - incapsulation of VLAN, QinQ, MPLS is supported; 
    -    - support of asymmetric traffic routes, including processing of outbound traffic only; 
    -    - support of mirrored traffic; 
    -    - provides many other useful capabilities, unlike dedicated filtering solutions. 
    -  - "Four nine's" reliability: 
    -    - works 24×7 with no breaks and service delays; 
    -    - uptime of the systems already installed is many months; 
    -    - the Bypass mode is supported to calm the operator. 
    -  - Cost saving: 
    -    - DPI runs on a general purpose computer; 
    -    - support costs are almost zero - everything is automated; 
    -    - no need to waste money and time to develop and support own solution; 
    -    - a proxy hardware would cost much more to achieve the similar traffic capacity.
