Freshservice offers a default wildcard SSL for all users who have a support portal on a freshservice.com domain. This can be used as long as you continue to use the default Freshservice URL you signed up with (for example, yourcompany.freshservice.com). However, the default SSL does not work when you have pointed a custom domain name to your help desk portal (for example, helpdesk.yourcompany.com).
In this case, you will have to configure a custom SSL certificate provided by Freshservice with your domain name. For this, you will need access to your domain control panel in order to add a DNS record to your custom domain. If you are on the Estate plan, you can request an SSL certificate from Freshservice without any additional charges.
Setting up custom SSL on your support portal:
If your account has more than one workspace, navigate to Admin > Global Settings > Account Settings > Service Desk Security.

Note: The custom SSL certificate will only work as long as your support URL and the URL you mentioned while submitting a request are the same. In case you reconfigure your Freshservice to point to a different domain, your connection will no longer be secure.
