Checking a guard or a security company in Connecticut

This page is for whoever is doing the checking — a client, a property manager, a company vetting a subcontractor. It tells you what a guard and a guard company are supposed to hold in Connecticut, and walks you to CT Dept. of Emergency Services & Public Protection, Special Licensing and Firearms Unit’s own records to confirm it.

tessura is not a Connecticut agency and issues nothing. Every link below goes to the regulator, and the regulator’s answer is the one that counts.

Check the guard

Connecticut issues a credential to the guard, so you can check the person in front of you.

What they should hold

Every guard working a postSecurity Officer Identification Card (Guard Card)8 hrs of training · renews every 5 years
If they carry a firearmArmed Security Officer Firearms Endorsement (Blue Card)renews every 5 years

Armed work: Armed officers (21+) need a separate firearms endorsement with a state-approved course and an 8-hour annual refresher and qualification.

How to check it

  1. Ask the guard to show the physical Security Officer Training Certification Identification Card issued by DESPP SLFU, and note the name and card number. These cards run five years unless suspended or revoked.
  2. Ask the security company for its Connecticut private security company licence number, and ask it to confirm the guard is registered to that licence with SLFU — under C.G.S. 29-161q the employer is legally responsible for making sure the officer holds a card before registering them.
  3. If the guard will be armed, ask separately for the Security Officer Firearms Permit ('blue card'); the training certification card alone does not cover a firearm.
  4. Email DESPP.SLFU@ct.gov or call (860) 685-8046 with the guard's name and card number and ask SLFU to confirm the card is current and not suspended or revoked — do not use the state's eLicense site, which does not carry these records.
  5. Confirm with SLFU that the card's expiry is in the future and that the guard's registration under this particular employer is active, since registration is employer-specific even though the card is not.
Why there is no link to click

Connecticut does certify and register individual security officers through DESPP SLFU, but there is no public online lookup for them. I loaded the state's eLicense License Lookup (elicense.ct.gov/lookup/licenselookup.aspx) and searched its full credential-type dropdown: there is no Security Officer, Security Guard, Private Security or Private Detective entry (the only close match in the list is 'State Marshal'). eLicense covers Consumer Protection, Public Health, Agriculture and similar agencies, not DESPP special licensing. Verification is therefore by phone or email to SLFU.

Check the company

Connecticut Department of Emergency Services and Public Protection, Special Licensing and Firearms Unit licenses the firm itself here. This is the check most people skip, and it is usually the more important of the two.

What the firm must holdSecurity Service Agency LicenseIssued by Connecticut Department of Emergency Services and Public Protection, Special Licensing and Firearms Unit

How to check it

  1. Ask the company for the exact legal name on its licence and its Security Service Agency License number. A company that cannot produce a number for a licence it claims to hold has told you something.
  2. Open the Connecticut Department of Emergency Services and Public Protection, Special Licensing and Firearms Unit lookup and search for that name.
  3. Search the legal name, not the name on the uniform or the invoice. Brand names, DBAs, and the name on the truck are often not the licensed entity.
  4. Read the status and the expiry date, not just the presence of a record. An expired or suspended licence still returns a result.
  5. If nothing comes up, ask which entity holds the licence and in which state, then check that name. If the answer does not resolve, treat the licence as unconfirmed and call Connecticut Department of Emergency Services and Public Protection, Special Licensing and Firearms Unit before signing.

Ask for insurance properly

A licence says the state let them operate. Insurance is what stands between you and a claim, and it is the easier of the two to fake — a certificate is only true on the day it was printed.

Connecticut requires it by law

General liability of at least $300,000, filed before the licence issues and again at every two-year renewal.

Bond: $10,000 surety bond in favour of the state, posted with the Commissioner of Emergency Services and Public Protection and verified at each renewal.

The duty to report a change in insurance status within 30 days sits on the licensee, not the insurer — the party with the least reason to speak up. The bond, by contrast, is posted directly with the Commissioner.

If it lapses: Failing to notify the Commissioner within 30 days is itself a violation, but in practice detection is renewal-driven on a two-year cycle.

Conn. Gen. Stat. §29-161l(b) — https://www.cga.ct.gov/2025/pub/chap_534.htm

A certificate of insurance (COI) that names your business as an additional insured, not just the certificate holderCertificate holder means you were mailed a copy. Additional insured means their policy actually answers for you if you are pulled into a claim.
General liability, and workers’ compensation at your state’s statutory limitsIf a guard is hurt on your property and the company carries no workers’ comp, the claim tends to land on you. Ask for commercial auto too if they run patrol vehicles.
The policy number and the effective and expiry dates, on a certificate dated within the last monthAn undated or months-old certificate is the single most common tell. The dates let you ask the insurer about the right policy.
The name, agency, and direct phone number of the broker who issued it — then call themThe broker can confirm the policy is in force today. The certificate PDF cannot, and a forged or stale one looks identical to a real one.
A contract term requiring written notice to you before the policy is cancelled or non-renewedStandard certificates promise notice to the insured, not to you. Putting the duty on the company in the contract is what makes a mid-term cancellation a breach.
A fresh certificate part-way through the term, not only at signingRe-asking at 60 or 90 days costs you an email and defeats the whole get-the-COI-then-drop-it pattern.

tessura does not verify anyone’s insurance and has no access to insurers’ records. This is guidance for doing it yourself, not a statement about any company on this site. It is also not legal advice — for a contract of any size, have your own counsel or broker set the limits.

Where this comes from

Connecticut requirements last reviewed August 28, 2026. Some details on this state are still pending a second check against the primary source. Rules change — the regulator’s page is authoritative if it disagrees with ours.
