Calvis vs Walden Security: the short answer
Walden Security is a family- and privately-owned contract security company founded in Chattanooga, Tennessee in 1990 by Michael S. and Amy Walden. He had served seven years in the Navy before joining the Chattanooga Police Department in patrol and narcotics; she was a CPD dispatcher. From that start the company has grown to over 8,000 employees working across 49 states, the District of Columbia, and four U.S. territories, and it describes itself as the nation's largest privately-held, U.S.-owned security company. It is still headquartered in Chattanooga and still family owned.
Calvis is not a competitor to Walden in the ordinary sense, because Calvis is not a security company at all. Calvis is a marketplace that connects buyers with independently licensed local security agencies. It does not employ officers and it is not the security provider. You describe the coverage you need, compare vetted local agencies on published flat hourly rates, and book without signing an annual agreement.
So the useful question is not which company is better. It is which model matches the job. A federal courthouse post, a utility campus, or a multi-state institutional program is a contract-guarding problem, and Walden is purpose-built for it. A two-week gap after a termination, a Saturday event, a construction phase, or a single lobby post you want priced before a salesperson gets involved is a marketplace problem.

Who Walden Security actually is
Walden grew organically from a two-person, locally owned operation into national scope, rather than through the roll-up acquisitions that assembled most of the industry's largest names. That history is visible in the company today: same city, same family ownership, and an unusually formalized investment in its own quality and training apparatus.
The published service line is broad. Armed and unarmed officers, court security, mobile patrol, off-duty police officers, school security, concierge security, EMT-credentialed security, a special emergency response team, mobile surveillance trailers, event-based monitoring, remote access control, and live video monitoring all appear in its own materials. The industries it lists are just as telling: commercial real estate, education, banks and financial institutions, healthcare, government, logistics and warehousing, utilities, public transportation, hospitality and retail, manufacturing, residential, and arts and recreation. Those are sites with permanent posts, written post orders, and multi-year budgets.
Where Walden is genuinely strong
Federal contracting is the standout, and a marketplace does not replicate it. Metropolitan Security Services, Inc., doing business as Walden Security, was awarded seven U.S. Marshals Service contracts worth a combined $1.93 billion, announced in August 2023, to staff court security officers across the 2nd, 6th, 7th, and 9th through 12th federal judicial circuits. Court security officer work under the USMS program is not ordinary guarding. Officers screen everyone entering a federal courthouse, protect the building perimeter, and provide heightened coverage around sensitive trials, and the staffing pipeline runs through federal background investigation, medical and fitness standards, and clearance requirements that take months to satisfy. Building and sustaining that pipeline at circuit scale is a genuine competency, and it is one Calvis does not have and is not trying to acquire.
WBENC certification is an auditable qualification, not a marketing line. Walden is nationally certified as a Women's Business Enterprise by the Women's Business Enterprise National Council, and describes itself as the nation's largest WBENC-certified WBE specializing in security services. If your organization carries supplier-diversity spend targets, or your solicitation scores diverse-supplier participation, that certification can decide an award entirely independent of price or service quality. Very few security vendors operating at national scale can offer it.
Quality systems are formalized and third-party certified. Walden operates an ISO 9001:2015 certified quality management system and carries an ISNetworld Grade A safety rating. For institutional buyers who have to document vendor quality controls to an auditor, an insurer, or a regulator, a third-party-certified management system is a concrete answer rather than an assurance in a proposal.
Training is a sustained investment. The company has been recognized with Training magazine's APEX Award for eight consecutive years and holds a 5 Star Employer designation in the VETS Indexes Employer Awards. Awards are not outcomes, but eight straight years indicates a real curriculum organization rather than a slide in a pitch deck. Public employee sentiment tracks with it: at the time of writing, Walden's Glassdoor rating sits around 4.5 out of 5 across roughly 500 reviews, which is well above the norm for contract guarding. Worth noting in the same breath is that officer-level compensation scores materially lower than the company average in those same reviews, which is an industry-wide pattern rather than a Walden-specific one.
Licensing is published, not merely asserted. Walden lists its active security agency license numbers across 31 states and the District of Columbia. Publishing license numbers so a buyer can check them with the issuing regulator is exactly the behavior you want from any agency, and most do not do it.
Where buyers hit friction
Pricing is quoted, never published. Like every enterprise contract guarding firm, Walden prices per contract after a sales process. There is no rate card. Two buyers in the same metro can pay materially different bill rates for comparable unarmed coverage depending on contract size, term length, site risk, and how well they negotiated. If you want the number before you invest weeks in a sales cycle, that model does not accommodate you.
Contracts are the product. National contract guarding runs on annual or multi-year agreements, frequently with auto-renewal clauses and notice windows that are easy to miss. That structure is appropriate for a permanent post and badly matched to a seasonal, project-based, or uncertain need. Most buyers discover this the first time they try to scale coverage down mid-term.
The federal apparatus is overhead a small commercial buyer funds but never uses. Everything that makes Walden formidable on a USMS solicitation — the compliance infrastructure, the clearance pipeline, the certified quality management system, the contract administration layer — has to be carried by the company's cost structure. For a federal courthouse that is precisely what you are buying. For a single retail location that wants overnight coverage for three months, you are paying a share of an apparatus that contributes nothing to your post.
Short and sudden engagements are not the target. A firm optimized for multi-year institutional and government programs is structurally not optimized for a one-weekend event or a two-week fill-in. You can often get it done, but the timeline and the terms will reflect what the business was built for.
What Calvis is, and what it is not
Calvis is a marketplace, not a security agency. It does not employ officers. It connects buyers with independently licensed local security agencies that have been vetted before they can appear, then lets you compare them side by side on rate and credentials.
You see the rate before the sales call. Each agency's flat hourly rate is visible up front and priced by post type, so unarmed, armed, mobile patrol, and specialized coverage each carry their own published number. No discovery call stands between you and the price.
You compare several qualified agencies at once. Rather than running a serial vendor process — one proposal, one negotiation, repeat — you see multiple vetted local options for the same post together. That is ordinary comparison shopping, which the enterprise contracting model structurally does not offer.
There is no annual minimum to begin. Book a single shift, a weekend, an event, a construction phase, or ongoing recurring coverage. Contract length matches the actual job rather than a vendor's default term.
Vetting happens before the guard arrives. Agency licenses and individual guard registrations are verified against state databases as a condition of an agency appearing on the marketplace, and every guard placed through Calvis holds a current state license issued to them and their employing agency. You can review credentials and GPS-verified patrol records in your dashboard. Licensing always attaches to the agency and the officer, never to Calvis.
The honest limit, stated plainly: Calvis cannot bid a federal solicitation, does not hold facility clearances, and is not built to replace a national master services agreement covering hundreds of sites under one invoice with a dedicated corporate program manager. Those are exactly the things Walden exists to do.

Head-to-head: how the two models compare
| Factor | Walden Security | Calvis marketplace |
|---|---|---|
| What it is | National contract security company that employs its own officers | Marketplace connecting you to independently licensed local agencies |
| Founded / ownership | 1990, family and privately owned, Chattanooga TN | Marketplace operator; agencies are independently owned |
| Scale | Over 8,000 employees across 49 states, DC, and four U.S. territories | Network of vetted local agencies, compared per metro |
| Federal contracting | Yes; nearly $2B in USMS court security officer contracts | No; not a federal prime contractor |
| Supplier diversity | Nationally certified WBENC Women's Business Enterprise | Depends on the individual agency you select |
| Quality certification | ISO 9001:2015 certified QMS, ISNetworld Grade A | Agency-level vetting and credential verification |
| Pricing visibility | Quote-based, negotiated per contract, not published | Flat hourly rates published up front, by post type |
| Contract minimum | Typically annual or multi-year with auto-renewal | None required to start |
| Vendor choice | One vendor, one proposal | Multiple vetted agencies compared side by side |
| Speed to first shift | Sales cycle, contracting, then mobilization | Fast; agencies with local bench respond directly |
| Best fit | Federal and institutional programs, permanent posts, multi-site | Single sites, events, projects, seasonal and short-notice coverage |
| Credential visibility | On request during onboarding | Guard licenses and patrol records visible in dashboard before arrival |
Read down that table and the split is clean. Walden optimizes for depth, compliance, and continuity on long-horizon, high-requirement sites. Calvis optimizes for choice, price transparency, and speed on coverage that is short, sudden, or simply does not justify an annual agreement.
The federal question: where Walden simply wins
This deserves its own section because it is the one place the comparison is not close.
Federal guarding is a distinct market with its own rules. You need a registered entity with the right NAICS codes, past performance the contracting officer can verify, Service Contract Act wage compliance, officers who can pass federal background investigation and in many cases hold clearances, and the administrative capacity to survive a protest. Walden has all of it and has demonstrated it at circuit scale under the U.S. Marshals Service court security officer program.
A marketplace does not do that work and should not pretend it can. If your requirement arrives with a solicitation number, if the site is a federal facility, or if your scope references clearance-holding officers or an SCA wage determination, you are shopping for a federal prime contractor, and Walden belongs on that list. Our guide to federal government contract security guard services covers what that procurement path actually involves and what disqualifies a vendor early.
Where this matters for buyers who are not federal: the same capability is priced into every contract Walden signs. That is not a criticism of the company, it is how cost structures work. It just means a small commercial buyer should ask honestly whether they are buying the capability or subsidizing it.
Pricing: the real difference
We will not publish an invented hourly figure for Walden, because the company does not publish one and any number you find quoted online is somebody's guess. What can be stated accurately is how the two pricing models behave.
Contract guarding bills at a negotiated rate covering officer wages, payroll burden, insurance, supervision, compliance infrastructure, and corporate overhead, and that rate is fixed for the term. Your leverage exists at negotiation time and effectively nowhere else. Larger contracts get better rates, which means a single-site buyer gains nothing from the vendor's national scale while still funding its share of the overhead.
Marketplace pricing inverts that. Because agencies compete for the same posted job and rates are visible before booking, price discovery happens up front rather than behind a sales process. For a single-site buyer this usually removes the national-overhead premium entirely, since you are contracting with a local agency carrying far less corporate structure.
For a fuller breakdown of what actually drives an hourly guard rate, see our security guard cost guide and the direct national versus on-demand cost comparison. If you are weighing scale against locality more broadly, national versus local security guard companies covers that trade-off in detail.
Speed to coverage
This is where the two models diverge most sharply, and it is frequently the deciding factor.
Standing up a Walden post involves a sales cycle, a proposal, contract negotiation, and then mobilization: recruiting or reassigning officers, writing post orders, running background checks, and onboarding. On a federal contract that timeline is measured in months and every step of it is load-bearing. For a permanent commercial post it is entirely reasonable, and the front-loaded work is what makes the program good.
If your need is measured in days, that same process is a mismatch. Marketplace coverage moves faster because local agencies with an existing bench respond to a posted job directly, with no contracting phase in between to compress. The gap is widest on same-week and last-minute requirements — see emergency and short-notice security and our guide to same-day emergency security guards.
Licensing and compliance
Every state licenses security agencies and individual officers through regulators such as BSIS in California, DPS in Texas, and equivalent boards elsewhere. That license always sits with the agency and the individual officer, never with a broker or a marketplace.
With a national firm you are trusting one corporate compliance department. With Walden that trust is better supported than most, because the company publishes its state license numbers rather than asking you to take a certificate at face value, and its quality management system is externally certified. On the Calvis marketplace, agency licenses and individual guard registrations are verified against state databases before an agency can appear, and you can review each officer's credentials in the dashboard before the shift begins. Calvis only partners with licensed agencies; it does not hold or claim a guarding license itself.
If you are evaluating any agency outside a marketplace, our guide on how to vet a security guard company covers the checks that actually matter, starting with confirming the agency license through the state regulator directly.
Which one should you choose
Choose Walden Security if:
Your requirement is federal, or is likely to become federal. You need officers who can pass federal background investigation or hold clearances. You are staffing permanent posts at fixed institutional sites — utilities, hospitals, courthouses, corporate campuses, transit systems — with multi-year budgets. You have supplier-diversity spend targets that a WBENC-certified vendor helps you meet. You have to document vendor quality controls to an auditor or insurer and want a third-party-certified management system behind the answer. You are running multiple sites across states and want one accountable vendor under one agreement. In every one of those cases, a marketplace is the wrong instrument and we would tell you so.
Choose Calvis if:
Your need is a single site, an event, a construction phase, a seasonal window, or short-notice coverage. You want to see the hourly rate before entering a sales process. You do not want an annual contract with auto-renewal for coverage you may not need in six months. You want to compare several vetted local agencies rather than evaluate one proposal in isolation. You want guard credentials and patrol records visible in a dashboard rather than requested by email. For an office or mixed-use property specifically, see commercial security; for ongoing fixed-site programs, contract security services.
If you are genuinely between the two
Run both. Contract the national firm for the long-horizon, high-requirement portion of your coverage and price the variable portion through the marketplace. Buyers with a permanent core post plus fluctuating overflow needs frequently end up here, and it is usually cheaper than sizing one long-term contract to peak demand and paying for that peak year-round. For a wider field of options, see our best security companies roundup, and if you are weighing hiring directly instead, in-house versus contract security covers that math.
