Filtering by the Russian Internet Blacklist

In order to comply with Federal Laws FZ-114 and FZ-139, an operator has to block websites that are included in government blacklists for containing illegal information and to restrict access to illegal web resources.

VAS Experts DPI cuts down on the extra costs of developing and maintaining an in-house solution.

The platform is easy to integrate into your infrastructure, supporting flexible scaling and filtering traffic without affecting user experience.

VAS Experts DPI has proven to be an efficient solution that hundreds of operators in the Russian Federation use to filter websites by the Russian Internet Blacklist.

VAS Experts DPI has successfully passed testing by Roskomnadzor between September 13, 2017 and October 13, 2017. The testing results are available on the Roskomnadzor official website or can be requested from ITGLOBAL.COM managers.

VAS Experts DPI can be used to restrict access to Internet resources in compliance with the traffic filtering requirements of Federal Laws FZ-114, FZ-139, FZ-149, FZ-187 and FZ-398, Roskomnadzor blacklist and the Federal List of Extremist Materials of the Ministry of Justice.
