Procyon Security Group was registered as a General Partnership in the Province of British Columbia in March 2003. The Group takes its name from Procyon (PRO•see•on), the primary star in the constellation Canis Minor and the eighth brightest star in the sky. Proycon, meaning "ahead of the dog" in Greek, was used by sailors in ancient times as a navigational aid. From early autumn, it rises in the east well before Sirius and is one of the brightest stars in the Northern Hemisphere.
