The short answer
If you need someone to stock shelves, run a front desk, or cover a warehouse shift, a general staffing agency is the right tool. If you need someone whose job is to protect people or property, deter theft, control access, or respond to an incident, you are almost certainly in regulated territory, and in most states that work can only be furnished by a licensed security agency.
The distinction is not a branding preference. Most states define the regulated activity around the act of furnishing guards. California's Private Patrol Operator statute, for example, reaches any person or company that agrees to furnish a watchman, guard, patrolperson, or similar person to protect persons or property. Read plainly, that language does not care whether the business calls itself a security company, a staffing firm, or a labor broker. If it supplies guards for hire, the licensing regime applies. Requirements vary meaningfully state to state, and the state regulator is the authority on your specific situation, but the general shape holds nearly everywhere.
The practical consequence is that sourcing guards through a general temp agency usually means one of three things: the agency actually holds a security license and is simply marketed as staffing, the workers are not really doing security work, or someone is operating outside the licensing regime. Only the first two are comfortable places to be.

What each model actually is
General staffing agency
A staffing agency is a labor intermediary. It recruits, screens, payrolls, and places workers into client sites across many industries: light industrial, clerical, hospitality, logistics, events. Its core competencies are volume recruiting, payroll administration, and fast fill times. It bills a wage plus a markup, typically somewhere in the 35 to 60 percent range depending on market and volume, and the worker remains the agency's W-2 employee.
What the staffing model is built to absorb is employment administration: payroll taxes, workers' compensation, unemployment, and the recruiting cycle. What it is generally not built to absorb is the specialized regulatory and insurance burden that attaches to protective work.
Licensed security agency
A security agency is a regulated operator. In most states it must hold a company-level license (called a Private Patrol Operator license, a security agency license, a private security business license, or a similar name depending on jurisdiction) that is separate from and in addition to the individual registrations its officers carry. Qualifying for that company license commonly involves a documented experience requirement for the qualifying agent, a criminal history check through state and federal channels, a written examination on the state's private security statute, and proof of insurance and bonding at levels the state sets.
That agency then employs officers who each hold their own state-issued registration, obtained through a background check, fingerprinting, and a required training curriculum. Armed work sits behind an additional and separate firearms permit, usually with its own training hours and periodic requalification.
The gap between the two models is not effort or good intent. It is a body of law that only one of them is structured to satisfy.
Head-to-head comparison
| Factor | General staffing agency | Licensed security agency |
|---|---|---|
| Company-level state license to furnish guards | Typically not held | Required in most states |
| Individual worker credential | General employment eligibility | State-issued guard registration or guard card |
| Pre-assignment training | Client orientation, safety basics | State-mandated curriculum, commonly 8 to 40+ hours |
| Armed capability | Not available | Available with separate firearms permit and requalification |
| Insurance written for protective work | Rarely; assault and battery and use-of-force exclusions are common | Written for security class, with the relevant endorsements |
| Workers' comp classification | Light industrial or clerical class codes | Security guard class code, priced for the exposure |
| Use-of-force policy and post orders | Generally none | Standard operating requirement |
| Incident reporting and documentation | Ad hoc | Formal reports, patrol logs, chain of custody |
| Supervision after placement | Placement ends the relationship | Field supervisor, on-call escalation |
| Who absorbs an incident | Ambiguous, and often falls back on you | Agency's security-specific coverage responds first |
| Best fit | Non-protective labor, front desk, greeters, event ushers | Access control, patrol, deterrence, loss prevention, armed posts |
The row that matters most in a dispute is the insurance row. The rest of the table describes process. That one describes who pays.
Why the licensing question is not a technicality
Training and authority are not the same as presence
A licensed officer's training curriculum covers powers to detain and the limits of them, use-of-force standards, evidence and report writing, emergency response, and the legal boundaries of a private citizen acting in a protective capacity. Those are the exact decision points where an untrained worker gets a business sued: an over-aggressive detention, a physical intervention that should never have happened, a hands-on escort that becomes an assault claim.
A temp with no security training placed on a post is not merely less effective. They are being asked to make legal judgment calls they were never equipped to make, in a role that carries authority they do not formally have.
Insurance is written by class, and security is its own class
General liability policies for staffing firms are underwritten against the exposures of the industries they serve. Security work carries a distinct and difficult risk profile, which is why carriers writing it commonly attach assault and battery, use-of-force, restraint, and weapons exclusions unless a specific endorsement is bought. Claim denials in this space frequently trace to exactly that: an exclusion nobody read, or operations that were misrepresented to the carrier when the policy was bound.
Translated to your situation: a certificate of insurance from a staffing agency is not evidence that the specific event you fear is covered. The question worth asking is narrower than "are you insured." It is whether the policy responds to an assault and battery claim arising from security operations, and whether furnishing guards is a declared operation on the policy. Confirm coverage in writing rather than by handshake.
Negligent hiring and negligent security land on the property owner
Premises liability claims after an incident typically allege that the property owner failed to provide adequate security, or hired security that was unqualified, undertrained, or unsupervised. Plaintiffs' counsel will ask what credential the person on post held, what training they received, who supervised them, and what post orders governed their conduct. Sourcing that person through a channel with no answers to those questions is not a neutral choice, and the exposure does not stop at the vendor. Our guide on why licensed guards matter walks through how that plays out.
Where a staffing agency genuinely is the right call
This is not an argument that staffing agencies are bad. It is an argument about scope. There are real roles adjacent to security that are not security work, and paying licensed-officer rates for them is a waste of money.
- •Greeters, ushers, and ticket scanners at an event, where the job is wayfinding and hospitality, not deterrence or ejection
- •Front-desk receptionists who log visitors and issue badges but do not control access decisions or respond to incidents
- •Parking attendants and traffic directors handling flow rather than enforcement
- •Fire watch and safety observers where the state does not classify the role as private security, which is worth confirming, because several states do
- •Crowd-facing customer service at a venue where a separate licensed team handles the actual security posture
The failure mode is not hiring a temp. It is hiring a temp and then quietly expanding the role: asking the greeter to remove someone, asking the receptionist to confront a shoplifter, asking the parking attendant to detain. The job description at booking is not what a jury looks at. What the person was actually doing when the incident happened is.
If your scope creeps toward protection, deterrence, detention, or response, the role has changed classes and should be staffed accordingly. Our services overview breaks down which post types fall on which side of that line.
The cost comparison is closer than buyers expect
The intuition that a temp agency is dramatically cheaper usually does not survive an apples-to-apples comparison.
A staffing agency's bill rate is a wage plus a markup covering payroll taxes, workers' compensation, unemployment, and profit. A security agency's bill rate covers the same stack, plus guard licensing and registration fees, the mandated training hours, uniforms and equipment, security-class workers' compensation (among the highest-rated occupational classes in the country), security-specific general liability with the necessary endorsements, field supervision, and the compliance overhead of maintaining a company license in good standing.
The security rate is higher. It is not higher by the margin most buyers assume, because the staffing markup is already carrying a meaningful load, and because the security agency is spreading its compliance cost across a specialized book rather than bolting it onto a generalist one. In a metro where the underlying wage is the same, the difference between the two bill rates is often a modest number of dollars per hour.
Against that spread, you are buying a credentialed worker, a training record, security-class insurance, documented post orders, and an incident-response chain. That is a small premium for the only version of the arrangement that survives a deposition. See the security guard cost guide for what drives rates by post type and region.
Related but different: in-house, contract, and marketplace
Staffing agency versus security agency is a question about who is lawfully permitted to furnish the officer. That is separate from the question of whether you employ guards directly or contract them, which is an economics and control question covered in in-house vs. contract security guards.
Worth noting: many states treat proprietary in-house guards differently from contract guards, sometimes with a lighter registration path or a separate employer registration, on the theory that the employer is not in the business of furnishing guards to others. That asymmetry is one reason buyers get confused. It does not create a workaround. Routing guards through a general staffing agency is not the same as employing them yourself, and it does not inherit the proprietary treatment. Confirm the applicable rule with your state regulator before assuming either path.
Calvis sits in a third position. It is a marketplace, not a security agency and not a staffing firm. You describe the coverage you need and Calvis matches you with independently licensed local security agencies that have been vetted, then lets you compare them on rate and credentials in one place. The officers are employed and licensed by those agencies, and each agency's license is attributed to it through its state regulator. Every guard placed through Calvis holds a current state registration for the work being performed, verified before the shift rather than after an incident.
What to ask before you book, either way
Whether you are talking to a staffing firm that claims it can supply guards or a security agency you have not worked with, the same short list separates a real answer from a confident one.
- •What is your company-level license number for furnishing security officers in this state, and what is the issuing board? Then verify it yourself through the regulator's public lookup. Do not accept a screenshot.
- •Will the specific officer assigned to my site hold a current individual guard registration, and can I see it before the shift? Agency licensure and individual registration are two different things, and both matter.
- •Does your general liability policy list furnishing security services as a declared operation, and does it respond to assault and battery claims arising from that work? Ask for the endorsement, not the certificate.
- •What workers' compensation class code are these workers rated under? A security post staffed under a clerical class code is a problem waiting for its first injury.
- •Who supervises the officer once they are on site, and what is the escalation path at 2 a.m.? Placement is not supervision.
- •What post orders and use-of-force policy will govern their conduct, and who writes them?
If a vendor cannot answer the first three quickly and in writing, that is the answer. Our guide on how to vet a security guard company expands each of these into the documents you should actually collect.
The decision, compressed
Ask one question: is the person's purpose to protect people or property?
If no, a staffing agency is efficient and appropriate, and you should keep the role scoped so it stays that way in practice, not just on paper.
If yes, you need a licensed security agency, an officer with a current state registration, insurance underwritten for protective work, and supervision after placement. The premium over a temp rate is smaller than the exposure it retires, and it is the only structure that holds up when someone asks, after the fact, who that person on your property was and what qualified them to be there.
Licensing rules, training hours, and armed requirements vary substantially by state and change over time. Treat everything here as a general framework and confirm the specifics with your state's private security regulator or your own counsel before you staff a post.
