泛域名
泛域名证书又名通配符证书是SSL证书中的其中一种形式，一般会以通配符的形式(如：*.domain.com)来指定证书所要保护的域名。
OV证书和DV证书都会有通配符的域名形式提供，而EV证书一般没有通配符的证书形式。
1.配置灵活方便
由于采用了通配符的形式对域名进行配置，那么对于拥有多个二级域名的网站是一件非常便利的事情。只要申请一张通配符证书，就能用于所有的二级域名网站中。而且如果以后需要继续增加二级域名，也不需要再去申请购买证书，只需继续使用原有的证书就可以，对于网站管理者来说确实是非常的方便。
2.性价比高
一般而言，通配符证书是会比单域名证书会贵上不少，但是假如按每个二级域名的证书价格摊分下来，那其实证书单价是及其的低。当然这要看你的二级域名数量总数有多少而定。但如今互联网时代，很多公司企业他们都会用户多个二级域名。对于这些企业而言，通配符证书无疑是一种高性价比的SSL证书。
