Hiring security in Maryland? Here's who regulates it, what a company and its guards must be licensed to hold, how armed guards are permitted, and how to verify a license yourself in minutes.
Hiring a security company in Maryland? Confirming its license is the single most important check you can make — it's what tells you the provider is lawful, insured, and accountable, and it shields you from the negligent-hiring liability that comes with putting an unvetted, uninsured operation on your property. This guide covers who regulates security in Maryland, what a company and its guards must hold, how armed work is permitted, and exactly how to verify a license yourself.
In Maryland, security is regulated by Maryland State Police. A company must hold a Security Guard Agency License, and guards hold a security guard certification. Verify a license through Maryland State Police — Licensing Division.
What makes Maryland different
In Maryland the armed credential is a general Handgun Wear and Carry Permit rather than a security-specific firearm license, and there's no public self-service lookup — verify agency status with the State Police Licensing Division.
Maryland's armed credential is unusual: rather than a security-specific firearm license, an armed guard relies on the state's general Handgun Wear and Carry Permit — but security personnel face a heavier live-fire standard than ordinary applicants, qualifying with at least 50 rounds at a 70% score (versus 25 rounds for civilians). There's also no public self-service lookup, so you verify agency status directly with the Maryland State Police Licensing Division rather than a website. On the company side, agencies with five or more guards must carry $1,000,000 in general liability (and $500,000 for smaller firms) — one of the higher insurance floors in the country.
Who regulates security in Maryland
Private security in Maryland is regulated at the state level by the Maryland State Police, Licensing Division. A legitimate firm holds a Security Guard Agency License from Maryland State Police, meaning it has cleared the state's ownership, background-check, insurance, and record-keeping requirements. That license number is the first thing to confirm — ask for it in writing and verify it yourself on Maryland State Police — Licensing Division rather than trusting a certificate on the wall. The licensing authority can also suspend or revoke a license for misconduct, so a live status check tells you not just whether a firm is licensed, but whether it's in good standing.
What each security credential authorizes in Maryland
"Licensed" alone doesn't tell you what an officer is actually cleared to do — Maryland uses more than one credential, and they aren't interchangeable. Here's what each one authorizes:
| Credential | What it authorizes |
|---|---|
| Security Guard Agency License | Legally operate a company that provides guards for hire in Maryland (Bus. Occ. & Prof. Title 19, Subtitle 3); required of the business, issued by the MSP Licensing Division |
| Security Guard Certification | Work as an unarmed guard; requires 12 hours of initial training approved by the Maryland Police Training and Standards Commission, a background check, and employment by/application through a licensed agency; valid 3 years, renewed with 8 hours of MPCTC-approved continuing training |
| Security Guard Certification + Handgun Wear and Carry Permit | Work as an armed guard; the guard must hold both credentials and pass the 50-round Practical Police Course, and the agency must keep a valid handgun permit on file (COMAR 29.04.01) |
| Special Police Officer (SPO) Commission | Police-like arrest/detention power, but only on the specific property described in the commission; requires an 80-hour initial course, Livescan/FBI background check, Governor's commission on MSP recommendation, and — since SB 455 (2025) — can be sought through a licensed Security Guard Agency for its clients' property |
Guards and training
Individual officers in Maryland generally must hold a security guard certification, and the state requires training as set by the agency (confirm current state requirements). A valid company license doesn't guarantee every officer on the roster is credentialed and trained, so confirm the guards actually assigned to your site hold current registrations — verifying the company and the people are two separate checks.
Armed guards and firearms in Maryland
Arming a guard in Maryland takes more than the base credential: an armed officer needs a Handgun Wear and Carry Permit for armed work, with a minimum age of 21. Armed coverage also raises your exposure — a firearms incident can reach the client through vicarious-liability and negligent-hiring theories, and standard general-liability policies often exclude firearms — so confirm the specific armed credential (not just the base registration) and the firm's firearms coverage, and reserve armed posts for a documented threat. Our armed vs. unarmed guide covers the decision in depth, and you can compare armed security services directly.
Maryland does not issue a security-specific firearm license; armed guards must hold the same Handgun Wear and Carry Permit the Maryland State Police issues to any civilian, obtained through the MSP Licensing Portal. Because it is a general carry permit, it does not restrict the guard to concealed carry only — open or concealed carry on duty is a matter of employer/post policy rather than a statutory distinction. Applicants who list a security role must qualify on the tougher Practical Police Course (at least 50 rounds, no farther than 25 yards, 70% minimum) rather than the shorter civilian Basic Practical Handgun Course. The initial permit runs until the last day of the holder's birth month two years after issuance; renewals then run three years each, requiring an 8-hour refresher firearms course (versus the 16-hour initial course). Batons, OC spray, and handcuffs carry no separate state permit, though many agencies require in-house certification; under the Maryland State Police security guard regulations (COMAR 29.04.01) an agency may not allow an employee to be armed without a valid handgun permit on file.
| On-duty carry | Open or concealed — the Wear and Carry Permit itself does not mandate one mode; employer/post policy typically decides |
| Armed permit | Handgun Wear and Carry Permit (general MSP civilian carry permit, not security-exclusive) — security applicants must pass the harder 50-round Practical Police Course |
| Requalification | 8-hour refresher firearms course at each renewal: first renewal after 2 years, then every 3 years thereafter (no separate annual state-mandated live-fire requirement) |
| Other weapons | No state permit required for baton, OC spray, handcuffs, or tasers/stun guns; employer policy governs |
What security guards can and can't do in Maryland
Ordinary certified Maryland security guards have no special arrest power beyond what any private citizen holds — Title 19 grants certified guards no arrest authority. Under Maryland common law a private person may arrest for a felony committed in their presence (or a completed felony with probable cause), but for a misdemeanor only if it amounts to a breach of the peace committed in their presence. Retail guards instead rely on the merchant's privilege (Cts. & Jud. Proc. § 5-402), which immunizes a merchant or its agent from civil liability (false imprisonment, false arrest, slander, malicious prosecution) for detaining a person when there is probable cause to believe they committed theft of the merchant's property from the premises — it is a civil-immunity shield, not an arrest power. Guards seeking real arrest authority on assigned property must instead be commissioned as a Special Police Officer (Public Safety §§ 3-301 to 3-316) by the Governor on the recommendation of the Maryland State Police, which since 2025's SB 455 can now run through a licensed Security Guard Agency on behalf of its clients' property. SPOs get police-like arrest power strictly on the described property after an 80-hour course, a Livescan/FBI background check, and a 3-year commission renewed with 12 hours of in-service training.
How to verify a security license in Maryland
Verification takes only a few minutes and is the check that protects you:
- Get the license number in writing from the provider — don't accept a logo or a verbal claim.
- Open the official source — Maryland State Police — Licensing Division, not a third-party directory.
- Confirm the record is active, unexpired, matches the exact legal business name and address, and shows no disciplinary action.
- Verify the officers — confirm each holds a current security guard certification, plus the armed credential for any armed post.
- Confirm insurance and subcontracting — request a current certificate of insurance and confirm it meets or exceeds $1,000,000 general liability for agencies with 5 or more guards ($500,000 for smaller agencies), plus workers' compensation, and ask in writing whether any of your posts will be subcontracted to another firm.
Re-verify at renewal. Renewal in Maryland: every two years. A credential can also be suspended between renewals, so a check isn't one-and-done — re-check at renewal time and before signing a new contract.

Misdemeanor. Providing security guards for hire without a Security Guard Agency License (Bus. Occ. & Prof. § 19-601) is a misdemeanor under § 19-607, punishable by a fine of up to $1,000 and/or up to 1 year imprisonment; the Secretary may additionally levy administrative fines up to $5,000 per violation (capped at $10,000 per 2-year license term) for violations of §§ 19-313 and 19-408. (Md. Code, Bus. Occ. & Prof. §§ 19-601, 19-607). And the exposure isn't only the provider's — an operator who puts an unlicensed, uninsured guard on site inherits the negligent-hiring liability, which is exactly what a two-minute license check prevents.
