# cf.tls\_client\_auth.cert\_revoked

`cf.tls_client_auth.cert_revoked` Boolean

Indicates whether the request presented a valid but revoked client certificate.

When `true`, the [`cf.tls_client_auth.cert_verified`](https://developers.cloudflare.com/ruleset-engine/rules-language/fields/reference/cf.tls_client_auth.cert_verified/) field is also `true`.

This field is only filled in if the request includes a client certificate for [mTLS authentication](https://developers.cloudflare.com/ssl/client-certificates/enable-mtls/).
