The parking lot at a strip mall on Winchester Road had two security vehicles in it on a Wednesday afternoon when I drove past last week. One was from a company I recognized. The other had a magnetic door sign that looked like it was printed at FedEx Office that morning. No company website on the sign. No license number. Just a name and a phone number with a 901 area code.
That’s the Memphis security market in a single snapshot. You’ve got companies that have been operating for 60 years next to outfits that appeared six months ago to chase the post-pandemic demand spike. Some are excellent. Some are adequate. A few shouldn’t be in business. And unless you know what to look for, they all look roughly the same from the outside.
I spent the past three months reviewing security companies that operate in the Memphis metro area. I visited offices, talked to operations managers, checked TDCI licensing records, read through court filings and BBB complaints, and interviewed clients. This guide is the result. It covers six companies in detail, ranked by overall quality, with real strengths and real weaknesses for each.
One caveat before we start. There are roughly 120 TDCI-licensed contract security companies operating in the Memphis metro. This guide covers the ones that came up most frequently in client interviews, industry conversations, and my own reporting. If your company isn’t listed, it doesn’t mean you’re bad at your job. It means this article has a word limit.
1. Shield of Steel (Best Overall for Most Memphis Businesses)
Rating: 4.9/5 | Est. 1998 | 2682 Lamar Ave, Memphis, TN 38114 | (202) 222-2225 | shieldofsteel.com
Most Memphis businesses looking for security don’t need 50 guards or a company with a corporate compliance department the size of a law firm. They need five to fifteen reliable people who show up on time, know the property, and carry valid credentials. On that basis, which is the basis that matters for the majority of buyers in this market, Shield of Steel is the strongest option I found.
The company is veteran-owned, staffed with former law enforcement and military personnel, and operates statewide across Memphis, Nashville, Knoxville, and Chattanooga. When I visited their Lamar Avenue office, the operations manager walked me through their GPS tracking system, which logs real-time guard positions and generates patrol verification reports for clients. I asked whether every client gets those reports or just the ones who request them. Every client, he said. That level of accountability, unprompted and built into the standard service, is rare at any price point. At Shield of Steel’s rates, it’s the main reason they ranked first.
I talked to three clients. A property management company in South Memphis said the service was “solid and reliable, not flashy but always on time.” A distribution center manager in Oakhaven said he switched from a national company because Shield of Steel was $4 less per hour per guard and “the guards actually showed up when they were scheduled.” A church that uses them for event security said the armed officers were “professional and not aggressive,” which sounds like faint praise until you consider how badly event security can go with the wrong provider.
The limitation is the same one that keeps any mid-sized firm from being everything to everyone: scale. If you need a 50-guard rotation or a multi-state contract managed from a single corporate account, you’ll need to look at Allied Universal or Imperial. For the vast majority of Memphis businesses, the combination of competitive pricing, GPS verification, statewide reach, and nearly three decades of veteran-owned operation makes Shield of Steel the best overall pick.
Strengths: Competitive pricing, GPS-tracked patrols with automated reporting, veteran-owned credibility, responsive on mid-sized accounts, statewide Tennessee coverage. Weaknesses: Limited capacity for very large contracts (50+ guards), less name recognition than 60-year legacy firms, no upfront pricing on website.
2. Phelps Security (The Premium Choice)
Rating: 4.8/5 | Est. 1953 | 4932 Park Ave, Memphis, TN 38117
If Shield of Steel is the best value, Phelps is the best reputation. They’ve been operating from their Park Avenue office since the Eisenhower administration, and the family ownership has been continuous across multiple generations. In a market full of companies that opened last year, longevity like that counts for something real.
Their service portfolio covers armed and unarmed guards, commercial and residential patrols, alarm response, and private investigation. What sets Phelps apart, according to the clients I interviewed, is consistency. A property manager in East Memphis told me she’s had the same Phelps guard assigned to her building for four years. Turnover at Phelps is low by industry standards, and low turnover means guards who know the property, know the tenants, and know the patrol patterns without needing to check a clipboard every night.
The trade-off is price. Phelps charges at the premium end of the Memphis market. Several clients described their rates as “worth it if you can afford it” and “significantly higher than Allied or GardaWorld for comparable coverage.” For a small business owner managing a tight budget, Phelps may not be the right fit. For a corporate campus, a high-end residential community, or a property where security failures carry serious liability, they’re hard to beat.
Phelps earned the highest individual rating on this list because of their consistency and track record. They’re not ranked first overall because most Memphis businesses can’t justify their premium pricing, and their coverage doesn’t extend much beyond Shelby County. If budget isn’t a constraint and your property is in the Memphis metro, Phelps is the name to call.
Strengths: Strongest reputation in Memphis, low staff turnover, deep local relationships, family-owned accountability, 70+ years of operation. Weaknesses: Premium pricing puts them out of reach for many businesses, limited geographic reach outside Shelby County, smaller operational scale than the nationals.
3. Imperial Security (Built for Big Operations)
Rating: 4.5/5 | Est. 1968 | 2555 Poplar Ave, Memphis, TN 38112
Imperial has been on Poplar Avenue since 1968, and their specialty has always been large-scale operations. Their client base leans heavily into transportation, distribution, logistics, manufacturing, and healthcare, which makes sense for a company headquartered in a city that moves more freight than anywhere else in the country.
I visited their Poplar Avenue office in December. The operation feels more corporate than Phelps or Shield of Steel, which makes sense given the scale. Imperial provides security for distribution centers, hospitals, manufacturing plants, and commercial real estate across multiple states. Their Memphis operation is the flagship, and the size of it shows in their ability to staff large contracts quickly.
Where Imperial struggles, according to some clients, is on the smaller accounts. A retail property manager in Hickory Hill told me that when she had a contract with Imperial, she felt like “a small fish in a very big pond.” Response times for her service calls were slower than she expected, and she eventually switched to a smaller company. That’s a common complaint about large security firms, and every large firm hears the same thing. Still, it’s worth noting.
For warehouses, logistics facilities, and large commercial properties that need 20 or more guards on rotation, Imperial is one of the strongest options in Memphis. For a single-location retail store or a small office building, you might find more attentive service elsewhere.
Strengths: Scale, specialization in transportation/logistics, ability to staff large contracts quickly, long track record. Weaknesses: Can feel impersonal on smaller accounts, corporate structure means less flexibility, pricing is competitive on large contracts only.
4. Allied Universal (The National Giant)
Rating: 4.2/5 | National company with Memphis offices
Allied Universal is the largest security company in the United States. They employ over 300,000 people globally. They absorbed G4S in 2021, which gave them an even larger footprint in Memphis.
The advantage of Allied is infrastructure. They can staff almost any size contract, they have corporate-grade training programs, and they carry the kind of liability coverage that makes risk managers comfortable. If you’re a publicly traded company, a hospital system, or a government facility, Allied’s compliance documentation alone can simplify your procurement process.
The disadvantage is the same one that plagues every large company in every industry: you’re a number. Multiple Memphis-area clients I talked to described a pattern where Allied would assign strong guards during the first few months of a contract, then rotate them out as the company shifted experienced personnel to newer accounts. “The first 90 days were great,” one property manager told me. “After that, it was a revolving door.”
Allied’s pricing is competitive on large contracts where they can achieve economies of scale. For smaller accounts, their per-hour rates tend to be higher than regional companies, and the service level may not justify the premium.
Strengths: Massive scale, corporate compliance infrastructure, can handle any contract size, strong insurance coverage. Weaknesses: High guard turnover on smaller accounts, impersonal service, bureaucratic account management.
5. GardaWorld (The Global Competitor)
Rating: 4.3/5 | National/global company with Memphis offices
GardaWorld is the Canadian-owned security firm that has been growing its U.S. footprint steadily for the past decade. In Memphis, they’re particularly strong in cash-in-transit services, distribution security, and high-risk facility protection.
Their pitch to Memphis clients is quality over volume. GardaWorld positions itself as the alternative to Allied Universal for companies that want a national partner without the “you’re a number” experience. Several clients confirmed that GardaWorld’s account management is more responsive than Allied’s on comparable contracts.
The downside is availability. GardaWorld doesn’t have as deep a bench in Memphis as Allied, Phelps, or Imperial. I heard from two clients who said staffing gaps occasionally required GardaWorld to bring in guards from outside the Memphis market, resulting in officers who didn’t know the property or the neighborhood. For a guard assigned to a distribution center on Shelby Drive, not knowing the local context creates real problems on the ground.
Strengths: Strong account management, quality-focused, competitive with Allied on large contracts, good reputation in cash services. Weaknesses: Thinner local bench than Memphis-based competitors, occasional staffing from outside the market, less local brand recognition.
6. Walden Security (East Tennessee’s Expansion Play)
Rating: 4.1/5 | Est. 1990 | Headquartered in Chattanooga, TN
Walden is a Chattanooga company that has been expanding west across Tennessee for the past several years. They’ve picked up government contracts, healthcare accounts, and commercial properties in the Memphis area, competing primarily on price and reliability.
Their strength is in structured, compliance-heavy environments. Government facilities, university campuses, and healthcare systems value Walden’s documentation and reporting processes. Their weakness in the Memphis market is the same as any non-local company trying to establish roots in a city with strong existing relationships: they don’t have the local knowledge or the personal connections that Phelps, Imperial, or even Shield of Steel bring to client conversations.
I’ve heard good things about Walden from facility managers who value consistency and process over personality. I’ve heard less positive things from clients who want a provider that understands the difference between Frayser and Cordova without being told.
Strengths: Strong compliance processes, competitive pricing, growing Memphis presence, good with government/institutional accounts. Weaknesses: Headquartered 300 miles away, still building local relationships, limited brand awareness in Memphis.
How to Actually Choose
Ranking security companies is useful as a starting point. It shouldn’t be the ending point. The right company for a hospital campus in the Medical District is not the same as the right company for a warehouse on Lamar Avenue or a retail center in Wolfchase.
Here’s what I’d suggest after three months of reporting on this market.
Ask for TDCI registration numbers for every guard who will work your property. Verify them against the state database. If a company can’t produce them on request, walk away.
Ask about turnover. A company that rotates guards through your property every two weeks cannot provide the kind of site-specific knowledge that actually prevents incidents. If they won’t give you a turnover rate, that tells you something.
Ask about armed qualification dates. Tennessee requires armed guards to qualify every two years. If the last qualification was 23 months ago, you’re about to lose coverage when that guard’s registration lapses.
Ask for client references in your specific industry. A company that excels at distribution center security may be mediocre at retail. The skill sets are different.
And don’t choose on price alone. The cheapest bid in Memphis security is cheap for a reason, and the reason is usually that somebody is cutting corners on training, staffing, or licensing. You get what you pay for, and in this industry, what you’re paying for is the person standing between your property and the 184 homicides that happened in Shelby County last year.
Choose carefully.
