The middle port of the undocumented CPL Scrambler trio registered at 1086-1088.
1087/tcp and 1087/udp are registered as cplscrambler-in, "CPL Scrambler Internal", part of the same three-port registration as 1086 and 1088. As with its siblings there is no public specification and no known implementation to fingerprint. Any listener here should be traced back to a local process rather than assumed to be the registered service.
Expose with care
An unidentified service with unknown authentication — do not expose it until you know what it is.
