Connecticut Private Security and Private Investigation Licensing Guide

How Licensing Works in Connecticut

Connecticut regulates both private security and private detective services through DESPP’s Special Licensing and Firearms Unit (SLFU) under Chapter 534 of the Connecticut General Statutes.

For private security services, Connecticut is agency-centered. Companies providing security services are licensed through SLFU, and individuals performing security officer duties must obtain the required SLFU-issued identification card associated with security officer training and certification. SLFU’s published guidance describes an approved training course process tied to issuance of the Security Officer Training Certification Identification Card.

Private detective services are governed under the same chapter but follow a distinct track. Connecticut licenses private detectives and private detective agencies under Chapter 534. Where investigative employees are used, SLFU guidance indicates that employer-issued identification cards may be required for investigators or agents working under a licensee, with specific content prescribed by the commissioner.

Operationally, Connecticut should be treated as a centralized state regime where both company-level licensing (for security firms and detective agencies) and the appropriate personnel identification or authorization requirements must be satisfied before regulated services are performed.

Operational Notes for Multi-State Firms

Connecticut’s security and detective services are administered through SLFU under a single statutory chapter, but the compliance pathways differ by service line. Firms should plan for company licensing (where applicable) plus role-specific personnel authorization, including security officer ID card requirements and any investigator identification card requirements tied to detective licensing.
