Port 2087 is primarily used for secure access to WebHost Manager (WHM), a popular web hosting control panel component of cPanel. This SSL-enabled port facilitates encrypted management of server and hosting configurations, allowing administrators to handle server tasks safely over HTTPS. It plays a crucial role in secure server administration in hosting environments where protecting credentials and sensitive operations is essential.

Which one is on your host

ask the machine, not the registry

The registry says what 2087 is registered to. What is listening on it right now is decided by the host, and only the host can be asked. Each of these prints the process behind the socket.

linux
ss -ltnp | grep ':2087\b'
macos
lsof -nP -iTCP:2087 -sTCP:LISTEN
windows
netstat -ano | findstr :2087

On Linux and Windows the process name comes back with the socket; on macOS lsof needs sudo to name a process that isn't yours. Match what it prints against the 2 entries above.

A port number is not a service. Anything may listen on 2087 — what you actually met is decided by the host, not the registry. If a service is missing here, it belongs in the registry.
