Sophos RMS
Sophos Remote Management System (RMS) is a proprietary communication channel utilized by Sophos security products for centralized management and command relay between managed endpoints and the Sophos Enterprise Console. This port facilitates the distribution of security policies, event notifications, and status updates, enabling administrators to efficiently oversee endpoint protection across enterprise networks..
Sophos Remote Management System (RMS) is a closed communication subsystem included with Sophos security products, primarily used to maintain a secure and reliable management channel. It typically operates over TCP port 8193 by establishing persistent outbound connections from endpoints to the Sophos Enterprise Console or Management Server.
RMS helps deliver policy changes, client software updates, event data, and security alerts from clients to the management platform. Behind the scenes, RMS relies on a message relay architecture that supports environments with Distributed Management, allowing scalable control of large and segmented networks. The protocol involved is proprietary and optimized for efficient, real-time data exchange, though it does not typically use built-in encryption.
This port is generally opened internally within enterprise networks to facilitate Sophos endpoint communications with their management servers but might be exposed externally in some remote management scenarios, which requires careful firewall configuration and monitoring.
