Technical Details

what runs on :6325

The service uses TCP and provides a management/control interface for Double-Take deployments; it is distinct from the service's replication data path. The application protocol is proprietary, and reliable public details about its handshake, framing, or default encryption are limited, so do not infer those properties from the port alone. A listener on 6325 is most plausibly a host running Double-Take software rather than a general-purpose operating-system service.

security overview

Treat this as a management interface: restrict access to trusted management hosts and private network paths, and do not expose it directly to the internet. A reachable management service may let an attacker who can authenticate interact with replication or recovery configuration; the proprietary protocol and limited public security detail are reasons to avoid assuming that traffic is encrypted or safe to expose.
