+<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|Deep Traffic Analysis Platform (DPI)]]
+Advantages:
+**1) Easy to use:**
+  * all rules are applied at one place: on DPI platform;
+  * the platform loads and applies rules from lists by itself.
+**2) Productivity:**
+  * the list includes up to 4 billion URL records. Its representation in memory is compressed;
+  * up to 65000 web-lists;
+  * traffic capacity up to 400 Gbpds per one CPU;
+  * unlimited scaling by simple installation of additional servers;
+  * propagation delay is less than 30 μs.
+**3) Functionality:**
+  * HTTP/HTTPS/QUIC protocols are supported for web filtering;
+  * URL for HTTP, SNI/CN for HTTPS/QUIC protocols;
+  * HTTP and HTTPS/QUIC traffic regardless of the service port being used;
+  * 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 and 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;
+  * analysis of out-of-order packets (with transmission sequence violations).
+**4) "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.
+**5) 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.
