# Setting up HTTPS with a Custom Domain

Using HTTPs with your FlashEdge distribution is easy and free, you just need to create and validate a TLS/SSL certificate for your FlashEdge CDN zone. For this, you need to have access to your custom domain DNS records (example.com). Every certificate automatically validates and adds any subdomain, like [www.example.com](http://www.example.com), api.example.com, or to be precise, \*.example.com, but it also works for lower-level subdomains.

{% hint style="info" %}
Certificates are provided by Amazon and are issued by the certificate authority recognized by Internet browsers. You can use them securely for any type of website/application that is also accessible via the public Internet.
