Users of public services are advised to install browsers that support the Russian communication security certificate, such as Yandex.Browser and Atom, for better access to the portal and other sites, the Ministry of Digital Affairs said.

"Some sites may not open now. This is due to problems in the work of certification centers that check the security and reliability of Internet resources. In order to have access to all sites and necessary online services, including public services, we recommend installing browsers that support Russian certificate," the ministry said in a message sent to users of the State Services.

It clarifies that "now such functionality is available, for example, in Yandex.Browser or Atom."

The Atom browser was developed by Mail.ru Group (now VK), it is a browser with VK Connect synchronization.

On March 4, the Ministry of Digital Transformation announced that regulations would soon be adopted to regulate the work of the national certification center for the free issuance of TLS certificates to Russian legal entities, which will help users maintain secure access to sites that have had their TLS revoked. TLS (Transport Layer Security) is a cryptographic protocol for organizing secure communications on the Internet.

The department clarified that it will be possible to obtain a TLS certificate on the State Services portal in a completely remote mode. All browsers and operating systems will have to support the operation of TLS certificates on sites that receive them, and a complete list of domains for which certificates have been issued can be seen on the State Services portal.

Google and Firefox are expected to block SSL enabled access to key government and banks sites by manipulating certification centers and revoking certificates.
