The legislation requires to restrict access to websites offering VPNs and similar proxy services that do not comply with the demand of the relevant state authorities to block internet websites, which contain information prohibited for dissemination in the Russian Federation. In 2017 the Law on Information was updated to include measures aimed at restricting the use of the information-telecommunication networks and information resources (internet websites, information systems, computer programmes) that procure access to the information networks/resources blocked on the territory of the RF. As from 2019, communication operators and/or owners of technological networks with autonomous system number are mandated to install special technological equipment that automatically blocks Internet websites access to which is restricted on the territory of the RF. An operator providing access to the Internet is also obliged to install in its communications network technical means to counter threats to the stability, security and integrity of the functioning of the Internet and the public communications network on the territory of the Russian Federation.See also official website of the Federal Supervisory Service in the sphere of communications, information technologies and mass media, https://rkn.gov.ru/mass-communications/p753/.
