Registered to LANDesk (now Ivanti) Management Suite for remote control of managed desktops.
IANA registered 9535 as mngsuite, "Management Suite Remote Control", in 2010 on behalf of LANDesk. It belongs to the endpoint-management agent that ships with LANDesk / Ivanti Endpoint Manager, alongside the agent's other ports in the 9593-9595 range. Nmap's service table still calls it man, an older name for the same listener. On a scan it means a managed Windows desktop or server with the vendor agent installed, not a general-purpose service you can talk to.
Do not expose
This is a remote-control plane for whole workstations. It belongs on a management VLAN reachable only from the management server, never on a public interface.
