Colorado Data Security & Breach Notification Law

Colorado law requires businesses that maintain personal information of Colorado residents to protect it with reasonable security, dispose of it securely, and notify affected residents within 30 days of determining a breach occurred, with notice to the Attorney General when 500 or more residents are affected. Vail Valley IT implements the security, logging and response planning that keep valley businesses on the right side of those rules.

Who Colorado law applies to

  • Any business or government entity that maintains, owns or licenses personal information of Colorado residents
  • Larger data controllers under the Colorado Privacy Act (generally 100,000+ consumers, or 25,000+ with data sales)

What Colorado law means for a small business

Colorado’s data security law (C.R.S. § 6-1-713 through 6-1-716) applies regardless of industry. It covers personal information such as Social Security numbers, driver’s license numbers, financial account numbers with access codes, online login credentials and certain medical and biometric data.

The 30-day notification window is one of the shortest in the country, which makes preparation essential. Encryption matters too: encrypted data is generally treated differently if the key was not also compromised.

Frequently asked questions

How long does a Colorado business have to report a data breach?

Affected Colorado residents must be notified no later than 30 days after the business determines a security breach occurred. If 500 or more Colorado residents are affected, the Colorado Attorney General must also be notified within 30 days.

Does the Colorado Privacy Act apply to small businesses?

Usually not. The Colorado Privacy Act generally applies to controllers that process data of 100,000 or more Colorado consumers a year, or 25,000 or more while deriving revenue from selling data. The separate data security and breach law applies to businesses of every size.
