# Enable auto-renewal of TLS certificates

This is done in two places:

* Separately for each Web DDoS instance in [Instances / TLS Settings / Enable Auto-Renewal TLS Certificate](/product-guides/web-ddos/interface/instances/tls-settings.md#enable-auto-renewal-tls-certificate).
* Separately for each Secure CDN instance in [Instances / Enable Auto-Renewal TLS Certificate](/product-guides/secure-cdn/interface/instances.md#enable-auto-renewal-tls-certificate).
