title: How can I check whether mutual TLS is enabled for a service?
weight: 11
---
The `istioctl` tool provides an option for this purpose. You can do:
{{< text bash >}}
$ istioctl authn tls-check $CLIENT_POD httpbin.default.svc.cluster.local
HOST:PORT STATUS SERVER CLIENT AUTHN POLICY DESTINATION RULE
httpbin.default.svc.cluster.local:8000 OK mTLS mTLS default/ default/istio-system
{{< /text >}}
Where `$CLIENT_POD` is the ID of one of the client service's pods.
Refer to [Verify mutual TLS configuration](/docs/tasks/security/mutual-tls/#verify-mutual-tls-configuration) for more information.
