-## API Shield
-
-To use API Shield to protect your API or web application, you must do the following:
-
-1. Use Cloudflare’s fully hosted public key infrastructure (PKI) to [create a client certificate](/ssl/client-certificates/create-a-client-certificate/).
-
-2. [Configure your mobile app or IoT device](/ssl/client-certificates/configure-your-mobile-app-or-iot-device/) to use your Cloudflare-issued client certificate.
-
-3. [Enable mTLS](/ssl/client-certificates/enable-mtls/) for the hosts you wish to protect with API Shield.
-
-4. Create WAF custom rules that [require API requests to present a valid client certificate](/api-shield/security/mtls/configure/).

-## Workers
+## Scope
 
-To authenticate Workers requests using mTLS:
 
-1. Use Cloudflare’s fully hosted public key infrastructure (PKI) to [create a client certificate](/ssl/client-certificates/create-a-client-certificate/).
-2. Create and use an [mTLS binding](/workers/runtime-apis/bindings/mtls/) to authenticate Workers connections.
