Stop communication between the agent and ITOM cloud services by removing an Agent Client Collector certificate. For example, there might be a security breach due to which you want to stop communication by revoking the agent's
certificate.

## Before you begin

Role required: agent_client_collector_admin

## Procedure

1. Navigate to AllAgent Client CollectorAgents.
2. Select the agent for which you want to revoke the certificate.
3. Select the Revoke Agent Certificate button.
4. Select the reason for certificate revocation.  
   For a list and explanation of the available revocation reasons, see [Agent Client Collector certificate revocation reasons](https://servicenow-prod.fluidtopics.net/h8iiEwHbl5Fk8yTjszu50A "The following table lists and describes the possible reasons for revoking an Agent Client Collector certificate to stop communication between the agent and ITOM cloud services.").
5. Select OK.  
   The agent's certificate is revoked and the ITOM cloud services layer has its certificate revocation list (CRL) updated.
