Which SSL Certificates Are Compatible with .RU Domains

NiceNIC's current support guidance states that only GlobalSign SSL certificates are compatible with .RU domains. Select a GlobalSign product for the exact .RU hostname instead of ordering another certificate brand.

If you're looking to install an SSL certificate for your .RU domain, it's important to know that only GlobalSign SSL certificates are compatible with .RU domains. Other SSL certificates may not be supported due to specific registry policies for .RU domains.


How to Get a GlobalSign SSL Certificate for Your .RU Domain
You can easily proceed with purchasing a GlobalSign SSL certificate for your .RU domain through NiceNIC.

  • Simply visit the NiceNIC SSL product page and select GlobalSign SSL when ordering the certificate.


  • After your order is successfully placed, please visit the SSL section in our Help Center, where we will guide you through the SSL installation process.

Frequently Asked Questions
Can I use a non-GlobalSign certificate for a .RU domain through NiceNIC?

The current NiceNIC support page says no. Choose GlobalSign unless NiceNIC Support confirms that the compatibility policy has changed.
Does GlobalSign compatibility guarantee issuance?
No. The order must still satisfy hostname, validation and certificate-authority requirements.
