You can choose your desired name followed by company name.
For example: sz.ruckuswireless.com
If you are going to buy a wild card cert then you just need the company name.
For example: *ruckuswireless.com
Note: Make sure to add DNS entry for the domain name you select or FQDN of the device.
If you have a CA signed wildcard certificate already, you can use it with SZ without buying a new one.
Please refer the article from here
, which explains how to create CSR and import the cert on SZ controller.
