 Custom Domain is a fully-managed service that enables you to configure a first-party subdomain over HTTPS.  You can then track event requests through your own domain (for example, `cdp.mydomain.com`), instead of the default (`segment.com`). Tracking events through your own domain allows for more secure and complete first-party data collection by reclaiming first-party data lost to browser controls. With a more complete view of your customer behaviors, you can build more robust profiles for greater attribution and ROAS.
