-Azure Container Apps supports environment level network encryption using mutual transport layer security (mTLS). When end-to-end encryption is required, mTLS will encrypt data transmitted between applications within an environment. It can also verify that the caller of an application exists within the environment. However, it is unable to distinguish which specific application is making the call as the same TLS certificate is used for all applications within the environment, so authentication for individual applications is not supported.
+Azure Container Apps supports environment level network encryption using mutual transport layer security (mTLS). When end-to-end encryption is required, mTLS will encrypt data transmitted between applications within an environment. Applications within a Container Apps Environment are automatically authenticated. However, Container Apps currently does not support authorization for access control between applications using the built-in mTLS.
 
 When your apps are communicating with a client outside of the environment, two-way authentication with mTLS is supported, to learn more see [configure client certificates](client-certificate-authorization.md).
