Security guard services is a high-volume category in both corporate supplier diversity and federally funded contracting. Large corporations with campus security needs, hospitals, transit systems, and airports all contract for security services and often have supplier diversity spending goals. The credential you need depends on which market you are pursuing.
NAICS 561612 (Security Guards and Patrol Services) is the primary code for companies providing guard services. If your firm also provides alarm monitoring or investigation services, additional codes apply (561621 for security systems services, 561611 for investigation services). This guide focuses on 561612 but the certification logic applies across the security services category.
Two certifications, two markets
NMSDC MBE certification is the credential for corporate supplier diversity programs. Fortune 500 companies, hospitals, universities, and large commercial real estate operators source security services from MBE firms to meet internal diversity spend targets. NMSDC certification is what their procurement teams look for.
DOT DBE certification is the credential for federally funded project work. Transit agencies, airports, and port authorities that receive federal transportation funding use security services and set DBE participation goals on those contracts. If your security firm wants to work at an FTA-funded transit system or an FAA-funded airport, DBE certification is what matters.
Both certifications require minority or disadvantaged ownership of at least 51% and genuine owner control. The document requirements are similar. Many security firms pursue both simultaneously, though each certification is managed separately.
Security-specific licensing requirements
Security guard companies face licensing requirements that most other service businesses do not. Before applying for either certification, your firm's licenses must be in order.
State licensing: Every state with a significant security industry regulates security guard companies. Requirements vary substantially:
- California: Requires a PPO (Private Patrol Operator) license from the Bureau of Security and Investigative Services (BSIS). Owners or qualifying managers must pass a background check and written exam.
- Texas: Requires a Security Services Company license from the Texas Department of Public Safety. Individual guards require guard cards.
- New York: Requires a Security Guard Company license from the Department of State.
- Florida: Requires a Class B license from the Florida Department of Agriculture and Consumer Services for security guard agencies.
Most states require that guards carry guard cards (individual registration), have completed specified training hours (typically 8–16 hours of pre-assignment training plus additional in-service hours), and pass background checks.
Operating without the required state license exposes your firm to fines and contract termination. Certifying agencies — both NMSDC councils and state DOT UCP offices — do not audit your licensing directly, but corporate clients and government agencies will conduct their own compliance checks before awarding contracts.
Armed security additional requirements: If your firm provides armed guards, the licensing requirements are significantly more stringent. States typically require additional training, separate licensing, and firearms qualification. Federal facilities contracting for armed guard services requires compliance with the Federal Property Act and often additional DHS or GSA requirements.
NMSDC MBE certification for security firms
The NMSDC process for a security guard company follows the standard MBE application structure. Specific documentation relevant to a security firm:
Business licenses: State security guard agency license, county/city business licenses, any specialized licenses for armed services or event security.
Insurance certificates: General liability (typically $1–5 million per occurrence for contract security), workers' compensation, commercial auto, and potentially professional liability if you provide security consulting.
Employee documentation: Guard card copies or training certificates are sometimes requested to demonstrate your workforce is licensed. Certifying agencies want to confirm your firm has actual qualified employees, not just a paper business.
Operational evidence: Sample guard service contracts, post orders (instructions for guards at specific client sites), schedules, and uniform samples are all evidence of a functioning security operation.
The site visit: NMSDC requires an on-site inspection. For a security firm, this means having a real office where your operations are managed. If you primarily manage from a home office, have documentation of your management systems: scheduling software, guard tracking applications, incident report systems.
The minority owner control question in security services mirrors the janitorial and cleaning industry. The minority owner does not need to personally stand guard at posts. They must make the real management decisions: client pricing, contract terms, staffing levels, quality assurance.
DOT DBE certification for security firms
Transit systems, airports, and port authorities that receive federal funding use security services and apply DBE goals to those contracts. The DBE process for a security firm is submitted to the state DOT's Unified Certification Program (UCP), but the relevant contracting agencies are often the transit authority or airport authority, not the highway department.
Personal net worth limit: $2.047 million excluding home equity and equity in the DBE firm. Annual gross receipts cap: $30.72 million three-year average. SBA size standard for 561612: $25 million in average annual receipts.
The same armed vs. unarmed distinction matters in DBE certification. Many transit and airport security contracts require armed officers, which means your licensing must specifically cover armed services in the relevant state.
A site visit is standard for DBE certification. The certifying agency will review your state security license, your office and operational infrastructure, and the disadvantaged owner's documentation of management control.
What contracts look like
Corporate contracts (MBE): Large office complexes, corporate campuses, data centers, hospitals, and retail chains source security services. Contract values range from $50K per year for a small office to $10M+ per year for a large multi-facility corporate account. Banks and financial institutions are active purchasers of MBE security services because they have formal supplier diversity programs with quantitative goals.
Transit security (DBE): Transit agencies — Metropolitan Transit Authority (New York), LA Metro, Chicago Transit Authority, MARTA (Atlanta) — all use security services and set DBE goals. Contract types include uniformed guard presence at stations, fare enforcement, and special event security. Individual station security contracts run $500K–$3M per year. System-wide contracts are larger but typically split into smaller lots accessible to DBE firms.
Airport security (DBE): FAA-funded airport projects and airport operators contract for non-TSA security services including perimeter security, access control monitoring, and checkpoint support. Major airports (Atlanta's Hartsfield-Jackson, O'Hare, LAX) maintain active DBE programs and specifically seek minority-owned security firms.
A concrete example: The Washington Metropolitan Area Transit Authority (WMATA) sets DBE participation goals on service contracts funded by FTA grants. WMATA's security contracts for Metro stations and rail facilities appear in their DBE procurement opportunities. DBE security firms have worked as certified participants on WMATA contracts in the $1M–$5M range for station security services.
Federal government security (not DBE/MBE): Federal agency security contracts — guarding federal buildings, courthouses, or military installations — are governed by the GSA's Federal Protective Service contracting framework. These are not DBE or MBE contracts; they are competed under Federal Acquisition Regulations with 8(a), HUBZone, or SDVOSB set-aside options. If you hold an SBA certification, these are a separate market worth exploring.
Pursuing both MBE and DBE
The administrative process for both certifications is similar enough that gathering documents for one largely prepares you for the other. Create a certification folder with:
- Three years of personal and business tax returns
- Personal financial statement
- Business ownership documents (operating agreement, articles of organization)
- State security guard agency license
- Insurance certificates
- Employee/guard records
- Sample client contracts
Submit to NMSDC through your regional council and to your state DOT UCP simultaneously. The SBA has reciprocity rules with some state DBE programs, but NMSDC certification does not directly satisfy DBE requirements or vice versa — they are separate credentials for separate markets.
How to apply
For NMSDC MBE: 1. Find your regional council at nmsdc.org/councils 2. Verify your state security guard agency license is current 3. Prepare ownership documents, tax returns, and insurance certificates 4. Submit through the NMSDC council portal and pay the application fee
For DOT DBE: 1. Find your state UCP office at transportation.gov/civil-rights/disadvantaged-business-enterprise 2. Complete the state application form with the same document package 3. Contact your target transit or airport authority's small business office after certification — many maintain their own DBE vendor lists separate from the state DOT directory 4. For federal building security contracts, separately explore 8(a), HUBZone, or SDVOSB options through certify.sba.gov
