Welcome to Colorado Security Alarm

Colorado Security Alarm has been serving business and residents of the Metro Denver Area since 1980 with only one goal.  Be totally focused on quality and integrity, not on mass marketing or high pressure sales.  Every system we design and install is custom tailored to fit your requirements, never a “one size fits all” mentality.

Most of our business is from referrals and word of mouth and we strive to keep it that way.  What other companies do you know of that try to do that?

Contact us today and we’ll set up your personalized quote and make sure you get exactly what you were looking for.  Safety and security are our business.

SPECIAL NOTE:  Sales people are going around the area indicating that “Colorado Security Alarm was sold six months ago, we’d like to sell you a new alarm!”   This is a blatant lie and we’re here and have been since 1980, as usual watching out for your safety!
