Why Citadel Intelligence?

Citadel Intelligence Was Founded on A Simple Principal

Citadel Intelligence Corporation was founded in 2004 by retired police officer, Greg Douglass in response to the tragedy of 9/11. Security had taken on a whole new meaning and an immediate need for increased security measures had arisen. The need for higher security standards and protocols came with the realization that the safety of companies and their employees was no longer something that could be taken for granted. Businesses which had not previously thought seriously about security, realized that they also were vulnerable. Citadel Intelligence was founded for the sole purpose to meet the security demands of our changing world and do it better than anyone else! The standard security practices of yesterday are now obsolete! Every business has its unique and individual security needs and safety concerns, and security today means protection from threats that is flexible, reliable and cost effective.
