As someone so aptly called it a Fortress of Solitude, that is exactly what it is!
Nicole Corp asserts that all animal visitors are welcome because they are cool. People, however, will be subject to stricter visitation rules. The lead engineer/founder of Nicole Corp will also develop a high powered weapon to be attached to the space station to ensure that anything requiring destruction can be done as efficiently as possible.
Also, don't try and visit the Fortress of Solitude because you weren't cool enough to be invited up. Nicole Corp employs a fleet of SR-71 fighter jets to shoot you down before you even get close to the edge of the atmosphere! These planes are capable of Mach 3+! That's twice of the speed of sound to those non-engineers.
Menacing isn't it? That is one of the Nicole Corp core values.
