    • For financial and payment enterprises, EV SSL certificates are recommended.
    • For general enterprises, OV SSL certificates and SSL certificates with a higher trust level are recommended.

    How do I choose a certificate provider?

    Choose an appropriate certificate provider based on each SSL certificate’s browser compatibility test report and your enterprise’s business requirements.
    For more information, see Browser Compatibility Test Report.

    How do I choose a certificate based on the number of supported domain names?

    Tencent Cloud provides the following 4 types of domain names:

    • Single-domain SSL certificate: only one domain name can be bound. This can be a second-level domain name like tencent.com, or a third-level domain name like example.tencent.com. However, binding all sub-domain names under a second-level domain name is not supported. Up to 100 levels of domain name are supported.
    • Multi-domain name: a single certificate can be bound to multiple domain names, subject to the maximum number of supported domain names stated on Tencent Cloud's official website.
    • Wildcard domain name: only 1 wildcard domain name with only 1 wildcard can be bound, such as *.tencent.com and *.example.tencent.com (up to 100 levels). A wildcard domain name with multiple wildcards like *.*.tencent.com is not supported.
    • Multi-wildcard domain name: multiple wildcard domain names with each containing only 1 wildcard can be bound, such as *.tencent.com and *.example.tencent.com (up to 100 levels). A wildcard domain name with multiple wildcards like *.*.tencent.com is not supported.
