Employees of the SyncWeb.ru cloud provider advised us and provided a service for issuing Sectigo PositiveSSL Wildcard (DV) SSL certificates for our publishings:
Moreover, we were provided with assistance in installing SSL certificates, as well as recommendations for configuring nginx on servers.
In particular, based on the results of the SSL Server Test from Qualys, Inc., employees SyncWeb.ru suggested to disable TLS 1.0 and 1.1 protocols because they do not support modern cryptographic algorithms. After these works and repeated testing, our publishings received the maximum rating of A+.
We were completely satisfied with our partnership with the SyncWeb.ru company, if you are currently interested in choosing a certificate and issuing it, I recommend SyncWeb.ru.
