+# Certificates in Azure Container Apps
+
+You can add digital security certificates to secure custom DNS names in Azure Container Apps to support secure communication among your apps.
+
+## Options
+
+The following table lists the options available to add certificates in Container Apps:
+
+| Option | Description |
+|---|---|
+| [Create a free Azure Container Apps managed certificate](./custom-domains-managed-certificates.md) | A private certificate that's free of charge and easy to use if you just need to secure your custom domain in Container Apps. |
+| Import a certificate from Key Vault | Useful if you use [Azure Key Vault](../key-vault/index.yml) to manage your [PKCS12 certificates](https://wikipedia.org/wiki/PKCS_12). |
+| [Upload a private certificate](./custom-domains-certificates.md) | You can upload a private certificate if you already have one. |
+
