What is the default TCP port for CyberArk CPM communication?

The default TCP port for CyberArk's Central Policy Manager (CPM) communication is TCP/1858. This port is specifically designated for securing communication between the CPM and other components of the CyberArk environment, such as the Vault and the Password Vault Web Access (PVWA). Using a dedicated port for CPM communication helps to ensure that the interactions between these components are managed more securely and reduces the likelihood of port conflicts with other services that may be running on common ports like 80 or 443, which are typically used for web traffic.

The selection of this specific port is part of CyberArk's configuration to facilitate efficient management and communication of privileged accounts and credentials across the organization's network environment. It is essential for users to be aware of this default setting for proper network configuration and troubleshooting within the CyberArk infrastructure.
