The basic network requirements to deploy a CyberArk Privilege Management Central Policy Manager (CPM) server include Port 1858 to the Privilege Cloud Vault service backend and Port 443 to the Privilege Cloud Portal. Port 1858 is necessary for communication with the CyberArk Vault, facilitating essential interactions like password retrieval and updates. Port 443 is required for secure web traffic to and from the Privilege Cloud Portal, ensuring that all management tasks performed through the web interface are secure and encrypted. These ports must be properly configured to allow for the efficient and secure operation of the CPM within the Privilege Cloud infrastructure.
