No Dark Corners is a new approach to defending institutions and infrastructure.  Building on Oscar Newman's Defensible Space and George Kelling's Fixing Broken Windows, No Dark Corners theory promotes a comparable sense of ownership to improve security on the job, as these other works did for housing and community applications. 

No Dark Corners is the title of an award winning master's thesis written by Nick Catrantzos in the Homeland Security graduate curriculum offered through the Naval Postgraduate School, Monterey, California.  It is also the title of a journal article published in the May 2010 edition of Homeland Security Affairs (, and the subtitle of the 2012 textbook, Managing the Insider Threat: No Dark Corners.

Catrantzos once worked for a discreet arm of public service and has divided some 30 years of intelligence and security experience between the public and private sectors.  Most recently, he has taught homeland security and emergency management after having focused on protecting critical infrastructure and institutions against terrorist threats.  A line and staff manager troubleshooting for underperforming organizations, building new ones, or representing others as a geographically separated factotum, Nick spent many years managing adverse consequences. 

Now he concentrates on preventing them.
