Technical Details

what runs on :44445

This is the Acronis Backup Gateway's TCP service port, used for backup-agent communication with the gateway. The traffic is Acronis-specific rather than a standard HTTP service; public documentation does not establish a general-purpose framing or handshake that can be identified from the port alone. Acronis backup communications are designed to be encrypted in transit, but do not infer a particular TLS handshake or cipher suite solely from the port number.

security overview

The service handles backup traffic and should be reachable only by the Acronis agents and networks that need to use the gateway. Restrict access with firewall rules and keep the Acronis software updated; an exposed listener is not evidence of a known vulnerability, but it does expose a sensitive backup service. Avoid treating it as a general-purpose service or opening it to the internet without a deployment requirement.
