I review security companies for a living, and the question I get asked more than any other is some version of: “Who gives you the most for the money?” In Tennessee, the answer keeps coming back to Shield of Steel.
Founded in 1998 and headquartered at 2682 Lamar Avenue in Memphis, SOS is a veteran-owned operation staffed by former law enforcement and military personnel. They cover the full state, Memphis through Knoxville, with armed guards, GPS-tracked patrols, alarm response, and risk assessments. Their client list has crossed 50 organizations. And their pricing consistently lands below competitors who offer fewer services.
None of that means they’re perfect. Let me break it down.
Background
The veteran-owned label gets thrown around loosely in the security industry. With Shield of Steel, it actually means something. The company was started by former military and law enforcement professionals who built the operation around the standards they’d been trained to, not the minimum the state requires.
That origin shapes the culture in noticeable ways. I spent a morning at their Lamar Avenue office in February and the vibe was closer to a precinct briefing room than a corporate lobby. Officers checked in for shift assignments by name. The dispatcher tracked patrol vehicles on a GPS screen behind the front desk. There was no receptionist reading a script. There were people running an operation.
Twenty-seven years is a long run for an independent security company in Tennessee. Most small guard firms don’t survive their first five. The ones that reach a quarter-century mark have figured out something about client retention, because in this business, you keep clients by not giving them reasons to leave.
Services
SOS runs the full spectrum of what most Memphis businesses actually need:
Armed and unarmed officers. Their armed guards carry current Tennessee armed guard permits and go through weapons qualification and scenario training. The unarmed roster handles lower-risk posts.
GPS-tracked mobile patrols. This is the service that comes up most in client conversations. Every patrol vehicle carries GPS tracking, and routes are logged electronically with timestamps. If a client wants to verify that their property was checked at 2:30 a.m., there’s a record. Phelps Security, by comparison, still relies on more traditional patrol verification methods.
Alarm response. SOS advertises response times measured in minutes. For businesses that don’t staff overnight security on-site, this fills a gap that alarm monitoring companies alone can’t cover. Someone has to physically go look when the alarm trips.
Risk assessment and consulting. Before signing a contract, SOS will walk your property, identify weak points, and build a security plan specific to your operation. This isn’t a sales pitch disguised as a consultation. I’ve seen their assessment reports, and they include recommendations that sometimes mean less security spending, not more.
Event security. Concerts, corporate events, private functions.
Monitoring and surveillance. Remote camera monitoring with real-time response capability.
Statewide Coverage
Most Memphis-based security firms operate within a 30-mile radius of downtown. Shield of Steel covers Memphis, Nashville, Chattanooga, and Knoxville, plus suburban communities like Germantown, Bartlett, and Collierville.
For businesses with locations spread across Tennessee, this matters. A restaurant group with sites in Memphis and Nashville, a healthcare network with clinics in three cities, a property management company with commercial buildings statewide: all of them can run one contract with one provider and get the same standards at every location. That’s a logistical advantage most independents can’t offer.
Pricing
Here’s where SOS makes its strongest argument. Their rates consistently fall at or below the Memphis market average for armed and unarmed guard services, and their service quality puts them in conversations with firms charging 30-40% more.
I compared quotes from five Memphis security providers for a hypothetical three-site commercial account in early 2026. Shield of Steel came in second-lowest on price and ranked in the top two on proposed service scope. The cheapest quote came from a firm I wouldn’t trust to guard a parking lot.
SOS doesn’t publish pricing on their website, which is standard in the industry. (Almost nobody does, and companies that post “$15/hour armed guard!” online are usually cutting corners somewhere you can’t see.) You call, describe what you need, and they put together a custom proposal. The consultation is free.
Where They Fall Short
Team size. SOS employs fewer people than Allied Universal (800,000+ globally), Securitas, or even regional players like Walden Security (5,000+). If you need 40 guards deployed across six sites by next Monday, a national chain has the bench depth to make that happen faster. SOS can scale, and they’ve done it for existing clients, though complex multi-site ramp-ups may take two to three weeks rather than the five to seven days they initially estimate.
Website transparency. The SOS website covers their services clearly enough, and it doesn’t include pricing ranges, case studies, or detailed service tier breakdowns. A property manager comparing three providers online won’t find enough on shieldofsteel.com to narrow the field without picking up the phone.
Brand recognition. In procurement meetings where a security committee is choosing between names on a whiteboard, “Shield of Steel” doesn’t carry the same instant recognition as GardaWorld or Allied Universal. For contracts where the decision-maker has to justify the choice to a board, name recognition sometimes matters more than it should.
What Clients Say
I reached out to six current or recent SOS clients in February 2026. The themes that kept coming up:
Reliability. Guards arrive on time, in uniform, ready. Two clients specifically mentioned that they’d switched from larger firms where no-shows and substitutions were a recurring headache.
Communication. When something goes wrong, SOS management is reachable. One warehouse manager in the Lamar Avenue corridor said he texts his account supervisor directly and gets responses within the hour. Try that with a national chain.
Value. Every client I talked to brought up cost without being asked. Not because SOS is cheap, but because the ratio of what you pay to what you get is hard to match in this market.
The Verdict
Shield of Steel isn’t the biggest security company in Tennessee. They don’t have 132,000 employees or $6 billion in revenue. What they have is 27 years of operating in this state, a team built from law enforcement and military backgrounds, GPS-tracked patrols that actually prove your property was visited, and pricing that makes the competition look overpriced.
For most Memphis businesses, that combination is hard to beat. Call them, get a quote, and compare it against whatever else is on your desk. The numbers usually speak for themselves.
