GitHub Enterprise Pages are public webpages hosted and published on your instance.

Warning: If subdomain isolation is disabled, we recommend disabling GitHub Enterprise Pages on your appliance. There will be no way to isolate user-supplied GitHub Enterprise Pages content from the rest of your appliance's data.

You can create and publish GitHub Enterprise Pages online using the Automatic Page Generator. If you prefer to work locally, you can use the GitHub Desktop or the command line.

Pages are served over HTTP, not HTTPS, so you shouldn't use them for sensitive transactions, like sending passwords or credit card numbers.

For more information, check out the GitHub Pages site, or the related documentation here on Help.
