Many users have noticed that websites of banks, online stores, and government services now show a warning 'Connection is not secure'. The reason is that the foreign certificate authority GlobalSign revoked SSL certificates for Russian companies. In response, companies are switching to certificates from the National Certification Center (NCC) of the Ministry of Digital Development. However, popular browsers like Chrome, Safari, Firefox, and Edge do not trust these certificates, so they consider the connection insecure and block access.
Problems arise when paying for goods and services, working with electronic document management, and participating in government procurement. For example, Lamoda's website displayed a warning about possible issues with card payments, and provider Xline reported failures when opening the payment module. Similar warnings appeared on the websites of RZD-Zdorovye sanatoriums and the industrial equipment store 'Mobile Cutting'.
The solution is to use a browser that supports Russian certificates. For instance, Yandex Browser for organizations works correctly with NCC, and websites open without errors. You can also use mobile apps of services, which often bypass this issue.
If you encounter such a situation, try updating your browser or switching to a domestic one. This will help avoid failures when paying and working with important services.
