Hi everyone,
In case you're not aware, it is not possible to put your Confluence or Jira behind a custom domain.
In my industry, sending a customer https://somethingtheydontrecognize.net/xyz rather than https://xyz.mycompany.com/ is a guaranteed way of creating confusion and damaging our customer relationships.
For this reason, my team has built a product called https://customdomainer.co/ — it's a way of customizing the URL of a Confluence/Jira site with your company's domain.
For example, you could use customDomainer to change https://yourcompany.atlassian.net/wiki/spaces/ to https://wiki.yourcompany.com/.
You can get started here: https://customdomainer.co/
