Colorado Investigator & Security Company Market Value Report.

Key findings

Colorado statewide market-size indicators

These figures are best read as a market-map signal. They show how many good-standing Colorado business entities use terms that commonly describe investigation, detective, security, guard, or patrol services.

Colorado security industry market value

The strongest public monetary baseline is the U.S. Census Bureau's 2022 Economic Census for NAICS 5616, investigation and security services. That dataset reports Colorado revenue, payroll, establishment, firm, and employment totals by industry code. These are historical receipts reported through the Economic Census, not a current-year forecast and not a count of licensed active operators.

Projection scenarios

Denver Security Review does not present these scenarios as an official forecast. They are simple growth-rate scenarios applied to the 2022 Economic Census baseline to show the scale of the category if Colorado investigation and security services grow at modest, moderate, or faster annual rates.

The important buyer-facing interpretation is that Colorado security and investigation is not a small informal market. It is a billion-dollar professional-services category with a large labor base, meaningful payroll, and many registered entities competing for trust-sensitive work.

2026 relevance update

The 2022 Economic Census remains the strongest public revenue baseline because sales and receipts are not published every year at the same industry detail. To make the report current for 2026 readers, Denver Security Review layers in newer official labor and employer datasets that show how the market looked after the 2022 revenue year.

May 2025 occupation wage indicators

These layers should not be merged into a single exact market-size number. The datasets measure different things: business revenue, employer establishments, covered employment and wages, occupations, and registered entity names. Read together, they make the 2026 conclusion stronger: Colorado's security and investigation market is large, labor-intensive, and still active after the 2022 revenue baseline year.

Denver and city concentration

For Denver businesses, the data suggests a crowded provider market. A large pool of entity-name matches does not automatically mean a large pool of mature, well-documented, properly supervised providers. That distinction is why review criteria should examine authority, documentation, confidentiality, supervision, and reporting quality.

Entity profile and term segmentation

Entity type and naming patterns help separate market signal from market noise. LLCs dominate both categories, which is expected for smaller professional services firms, regional providers, and owner-operated agencies.

Formation-year trend

Formation year is not the same as operational start date or current activity, but it does show when matched entities entered the public business registry. The recent security-related increase is notable and should be read alongside buyer diligence, not as a quality indicator by itself.

Methodology and limits

The primary source was the Colorado public business entity dataset. Denver Security Review filtered for good-standing entities with a Colorado principal state, then counted entity names matching terms commonly associated with private investigation and security-provider work.

This is not the same as a license registry. Some entities may be inactive in practice, may provide adjacent consulting or technology services, may operate under names that do not include these terms, or may provide services outside the buyer's intended scope. Colorado also does not provide a single clean statewide active private investigator list suitable for claiming an exact current operator total.

Security-industry regulation is also changing and contested. Colorado General Assembly materials for 2025 security-guard legislation show a proposed statewide regulatory structure, but the bill was lost and should not be mistaken for a current statewide list of active providers.

What this means for businesses

The practical takeaway is not simply that Colorado has many investigation and security-related business entities. The stronger takeaway is that buyers need a disciplined comparison process. Businesses should ask for clear documentation of authority, service scope, confidentiality controls, supervision practices, incident or case reporting, evidence handling, and client communication standards before selecting a provider.
