What Ports Does McAfee ePolicy Orchestrator (ePO) Use?
McAfee ePolicy Orchestrator (ePO) utilizes several specific ports to facilitate communication for its various operations, including agent-server interaction, database connectivity, and integration with directory services. These ports are crucial for the proper functioning and management of your endpoint security environment.Default ePO Communication Ports
The following table outlines the default ports commonly used by the ePO server for its outbound and inbound communication:| Port | Protocol | Traffic Direction | Common Use/Purpose |
|---|---|---|---|
| 389 | TCP | Outbound from ePO server | LDAP: Used for standard Lightweight Directory Access Protocol communication, often for authenticating users and synchronizing with directory services like Active Directory. |
| 443 | TCP | Inbound/Outbound to/from ePO server | HTTPS: This is a primary port for secure web access to the ePO console and for encrypted communication between ePO agents on client systems and the ePO server. |
| 636 | TCP | Outbound from ePO server | LDAPS: Used for secure LDAP communication (LDAP over SSL/TLS), providing encrypted authentication and synchronization with directory services, enhancing security. |
| 1433 | TCP | Outbound from ePO server | SQL Database: Essential for the ePO server to communicate with its SQL database, where all policy, event, and system information is stored. |
These ports are fundamental for ePO's functionality, enabling it to manage endpoints, enforce policies, and collect data across your network. Proper configuration and allowance of these ports in firewalls and network devices are vital for a healthy ePO deployment.
