The best security agency in Houston, TX is the one you can check before you sign. Reliable Guard & Patrol Service is licensed by the Texas Department of Public Safety under license B07315701, active since 2018, run by a team with 20 years on Houston posts. We staff about 150 licensed armed and unarmed officers at commercial sites across the metro. Every patrol is GPS-tracked and written up as a report you receive. There is no long-term contract, and we hand you a certificate of insurance the same day.
What makes the best security agency in Houston, and what does not
Star ratings do not tell you whether the officer at your gate is licensed, trained, or writing anything down. Five things do. The review-count lists that rank on this search skip every one of them.
Here is the standard we would use if we were the ones hiring a guard company. Run any Houston agency, including us, through it.
What to check | How to check it yourself | Why it decides the job |
Current state license | Search the company on the Texas DPS public license portal and read the license status, not the number alone. | A lapsed or missing license puts the liability and insurance exposure on you, the client. |
Right officer level for the risk | Ask whether the post calls for a non-commissioned (Level II) or commissioned (Level III) officer, and why. | Paying for armed coverage you do not need wastes money. Missing it on a cash or high-value post is worse. |
Proof the patrol happened | Ask to see the GPS tour log and a sample incident report before you sign. | A guard with no record is a guard you cannot defend later. |
Insurance that pays | Ask for a certificate of insurance and confirm the coverage meets the state minimums for a licensed company. | If an officer’s action puts you in a claim, the policy is what stands between you and the loss. |
A specialty that fits your site | Ask what kind of sites the company actually works. A firm that does everything rarely does yours well. | Construction, warehouse, and retail each fail differently. The officer should already know how. |
How to verify a Houston security company’s license yourself
You do not have to take any company’s word for its license, ours included. The Texas Department of Public Safety runs a public search, and it takes about two minutes. Do this before the first shift, not after the first incident.
- Open the Texas Online Private Security (TOPS) public license search, run by the Texas DPS Private Security Program.
- Search by company name or by license number. For us, enter B07315701 or search “Reliable Guard and Patrol Service.”
- Read the status. Confirm the license is current and free of open disciplinary issues. A number on its own is not enough.
- For armed posts, ask the company to confirm the assigned officer holds an active Level III commission. We give names on request.
Texas takes this seriously on its end too. DPS accepts and investigates complaints against licensed companies and can suspend or revoke a license for cause, and it files charges against people who work unlicensed. That enforcement record is public, which is the whole point: a real agency has nothing to hide from the portal, and a buyer who checks it removes most of the risk in one step.
Armed or unarmed: which your site actually needs
Most commercial posts in Houston are unarmed, and that is the honest answer even though armed bills for more. Deterrence and documentation handle the large majority of commercial loss, which is theft, trespass, and vandalism, not armed confrontation. Here is the line we draw with clients.
Unarmed (Level II) fits when | Armed (Level III) is worth it when |
After-hours patrol of construction sites, warehouses, vacant buildings, and offices. | The site handles cash on hand or high-value, easily resold assets. |
Access control, visitor checks, and observe-and-report. | There is a history of violent incidents at the location. |
Loss prevention at retail where the risk is shrink, not violence. | There is a credible, specific threat against people or property. |
Plenty of sites run unarmed patrol with a clear escalation plan and never need more. If you are not sure which way your post falls, that is exactly what the walkthrough is for. Compare our armed security guards and unarmed security officers side by side.

What a licensed Texas guard can legally do
A security officer in Texas has a private citizen’s authority, not police powers. That is the single fact that decides whether a stopped incident helps you or turns into a lawsuit against your property. What you pay a good agency for is an officer trained to use that limited authority correctly and to document it.
Under the Texas Code of Criminal Procedure Article 14.01, any person, including a security officer, may make a warrantless arrest only when a felony or a breach of the public peace happens in their presence or view. For theft, Article 18.16 lets any person recover property they have reasonable grounds to believe is stolen and hold the person while doing it. A detained person is turned over to police without delay. The officer does not file charges, transport, or jail anyone, and force is limited to what is reasonable under the same rules that apply to any citizen.
Being armed does not widen that authority. A Level III commissioned officer may carry a firearm on a high-risk post, but the legal limits are identical to an unarmed officer’s. The difference is deterrence and the response option, not extra power. An officer who oversteps creates liability for the property owner, so training, clear post orders, and a written record are what keep a stop defensible. If you want the fuller version, our guide on how a guard’s authority differs from police walks through it.

Proof every patrol happened, not a promise
The thing clients worry about most is whether the guard actually patrols or parks and scrolls. We answer that with a record you can pull up. Every officer runs a GPS guard-tour system with checkpoint scans, documented rounds, real-time incident reports, and supervisor check-ins. You see the activity on paper, and so does your insurer if it ever matters.
The entries below are representative incidents from our Houston patrol logs, with client names and exact addresses removed. They are the reason a documented officer on site beats a camera nobody is watching.
Copper wire, recovered. On a scheduled 3:30 a.m. round at a construction site, the officer found a storage container forced open and a person pulling out rolls of copper wire. He called police, held visual contact from a safe distance, and fed updates to dispatch. Responding officers made the arrest. The copper went back to site management, and the incident report went to the client the same shift.
Vacant building, entry prevented. Two people were prying at a boarded rear window of a vacant commercial building around 1:45 a.m. The officer called dispatch and police, kept watch from cover, and ran the patrol vehicle’s lights. Both left before getting in. A later check found minor damage to the window covering and no entry. The officer secured the site and notified the owner. Small thing, except it wasn’t, because the next visit could have been a fire or a squatter.
Warehouse dock, no loss. After hours at a distribution warehouse, an unauthorized vehicle sat near the loading docks while a person tried a secured storage area by the dock doors. The officer called dispatch and the site supervisor, identified himself, and directed the person off the restricted area. The person left. A dock-and-gate check came back clean: no forced entry, no damage, nothing missing.
Every one of these was GPS-logged and written up. That record is the point. It is what holds up with an insurer or in a dispute later, and it is what a review star can never show you.
The 6-point standard every officer clears before a post
Every officer clears the same six checks before a post, on every site, no matter the client. This is what turns “reliable” from an adjective into something you can audit.
- DPS license verification. Active Texas DPS registration is confirmed for the level the post requires, before deployment.
- Fingerprint background check. Full criminal background screening with fingerprint-based checks consistent with state requirements.
- Drug testing. Pre-assignment testing, no exceptions, armed or unarmed.
- Interview to standard. An in-person interview against company conduct and presentation standards, beyond the license check.
- Verified references. We contact and confirm references. We verify history, we do not assume it.
- Recurring training. Unarmed officers complete Level II training. Armed officers re-qualify on firearm proficiency and continuing education at each two-year license renewal.
Who we are not for
We would rather tell you now than take a job we do not run well. Reliable Guard & Patrol Service is commercial-only. We staff construction sites, warehouses, buildings, vacant properties, retail and shopping centers, offices, and hotels. Those posts are the whole business, which is why our officers already know them.
We do not take residential, HOA, or event work, and we do not run K-9, fire watch, alarm response, or parking enforcement. If that is what you need, we are the wrong call, and a specialist in those will serve you better. If your site is commercial, it is what we do all day.
Frequently Asked Questions
Do you require a long-term contract?
No. We bill weekly, month-to-month, short-term, or long-term, set to the job. The idea that you must sign for a year is a myth.
How fast can you start?
In most cases we deploy the same day. We start with a call, a free proposal, and a site assessment where it helps, then we put an officer on the post.
Are you licensed, and how do I verify it?
Yes. We hold Texas DPS company license B07315701. Search it yourself on the DPS public portal by that number or by “Reliable Guard and Patrol Service” and confirm the status is active.
What’s the difference between armed and unarmed officers?
An unarmed (Level II) officer patrols, controls access, and observes and reports. An armed (Level III) officer does all of that with a firearm for high-risk, cash, or high-value posts. Being armed does not change the officer’s legal authority, only the deterrence and response option.
Do you offer event security, fire watch, K-9, or residential service?
No. We are commercial-only and do not run events, fire watch, K-9, alarm response, parking enforcement, residential, or HOA work.
Are your officers background-checked?
Yes. Every officer clears fingerprint-based background screening, drug testing, license verification, an interview, and reference checks before a post.
Do you have Spanish-speaking officers?
Yes. We staff bilingual officers across the metro, and clients call this out most on overnight coverage.
How do you prove the patrols actually happen?
GPS guard-tour tracking with checkpoint scans, documented rounds, real-time incident reports, and supervisor check-ins. You get the record on paper, and your insurer can see it too.
