Looks like the regular symbols of a Masonic Lodge [1] so probably part of Free Masonry. I did work once for an affiliated organization and it was full of symbols and stuff like what you see there.
Other than the login, there's a quite interesting Code of Conduct. Name of company/org is just missing and it describes things like using electronic time cards and equal employment opportunity, which is kind of funny if it actually is freemasonry related (I think they would be one sex only)
