The Sites Dashboard enables you to add or update custom domains and SSL certificates for a site. To ensure domains resolve correctly and direct traffic to the site, you must also configure these domains with your DNS provider.

Note

The terms Transport Layer Security (TLS) and Secure Sockets Layer (SSL) are often used interchangeably. For consistency, Acquia documentation and the user interface generally refer to SSL. Acquia supports newer versions of TLS.

Adding a custom domain
----------------------

Important

If you use custom domains, you must install and activate an SSL certificate for the customer domain.

The following error message displays if the SSL certificate is not uploaded to the Acquia Source custom domain:

`Requested host does not match any Subject Alternative Names (SANs) on TLS certificate [eb705b55a9f4eae35aeb8d36c296b5903629cd18bc0fb6b] in use with this connection.`

To add a custom domain for a site:

1.  Log in to Acquia Source to open the Sites Dashboard.
    
2.  On the **Sites** tab, locate the site to which you want to add a domain.
3.  Click the title of the site.
4.  In the left navigation, click **Domains & SSL**.
5.  Click **Add Domain**.
6.  In the **Enter Domain** field, add the domain name.
7.  Click **Add**.
8.  Click **Done**.
9.  Click **View DNS information**.
10.  Copy the DNS records from the table and provide them to your DNS provider. 
11.  Manually update your DNS records with the records copied from Acquia Source.
     
     Note
     
     When you clone an Acquia Source site, the custom domain and SSL certificate details do not carry over to the cloned site. You must set these details for each site.
     

Adding an SSL certificate
-------------------------

SSL enables an application to use the HTTPS secure web protocol to securely communicate with users online. 

Acquia recommends implementing an SSL certificate to:

*   Ensure that domains follow standard internet security protocols
*   Protect visitors on domains

To use SSL:

*   You must purchase an SSL certificate from a Certificate Authority (CA) or SSL certificate vendor, and upload it to Acquia Source. Acquia is not a CA or SSL certificate vendor.
*   Sites must have an SSL certificate installed and activated.
*   The certificate must include coverage for necessary domains.
*   Acquia Source customers can activate more than one SSL certificate for each site.
