Ordering for more years will save you a lot of money! You can order TLS certificates for up to 6 years. You will receive the renewed follow-up certificate every year.
Save time. One order and payment = less administration.
The longer the validity of the order, the higher the savings due to the decreasing annual price.
You will receive the following one-year certificate automatically and on time, you just exchange it on the server.
Recommended certificate use
通配符 SSL 又叫泛域名证书,可以保护一个域名以及该域名所有的二级或者三级子域名,不限制子域名数量,且添加新的子域名无须重新审核和另外付费,节约了大量的时间和金钱成本。例如,一个单独的通配符证书就可以保护 certbase.com、blog.certbase.com 和 store.certbase.com。通配符证书可以保护通用域名和您在提交申请时指定的级别下的所有子域。只需在通用域名左侧的子域区域添加星号 (*) 即可。适用对象主要为银行、保险、金融机构、电子商务网站、大型企业等。
