Searching for the best security services companies in Houston, TX usually turns up the same mix: national brands, review-stuffed listings, and alarm sellers sharing the page with actual guard companies. This guide separates the manned-guard market from the noise. It shows you how to verify a company’s Texas license and officer level, what the state’s own complaint data says, and the questions that separate a documented officer from a drive-by. Reliable Guard & Patrol Service Inc. is a licensed Houston guard company (Texas DPS B07315701).
How to choose the best security company in Houston
The best security company for a Houston commercial site is the one that can prove three things before an officer starts: an active Texas Department of Public Safety license at the right level for your risk, coverage you can verify (GPS-logged patrols and written incident reports, not a promise), and a certificate of insurance in your name. Match the officer type to the actual threat, unarmed for deterrence and observe-and-report, armed for cash handling or a specific violent-threat history. Check the license yourself on the Texas TOPS portal, ask for the certificate of insurance the same day, and read the company’s complaint history before you sign. A company that shows you the paperwork without being pushed is usually the one worth hiring.
What "best" actually means in Houston’s security market
Houston’s security results blend three different businesses into one list. National firms bring scale and a large personnel pool. Local and regional guard companies compete on response time and knowing the post. And alarm and camera sellers show up in the same searches, often carrying the biggest review counts on the page. That last part trips up buyers. A five-star company with thousands of reviews may be rated for alarm sales and installs, not for how its officers perform on an overnight commercial post. Review volume measures how many customers a company has billed, not whether a guard showed up and did the job.
For a commercial site, the useful filter is narrower. You’re hiring a licensed officer to stand a post, document what happens, and hold up later with an insurer or in a dispute. That’s a different purchase than a home alarm. Judge it on license, officer level, proof of work, insurance, and whether the company actually staffs your type of site. The rest is packaging.
The license check most buyers skip and the numbers behind it
Everyone says to check the license. Fewer people actually do it, and fewer still know what it does and does not tell you. A license confirms a company met a bar to operate. It does not confirm the company stays clean.
The Texas Department of Public Safety regulates private security under Occupations Code Chapter 1702. Its Regulatory Services Division takes in around 700 private security complaints a year. In the FY2023 regulatory report, the division logged 789 complaints and referred 207 for disciplinary action. When investigators actually look into a complaint, they find a violation about 30% of the time, against roughly 10% on routine inspections. Most of those complaints come from other security companies, not the public, which tells you the people watching this industry closest are its own competitors.
So verify the license, then go one step further. You can check any Houston company in a few minutes:
- Open the Texas DPS Private Security public license search (TOPS), run by the Department of Public Safety.
- Search the company name or license number. For us, that’s Reliable Guard & Patrol Service, license B07315701.
- Confirm the license is active and free of open issues.
- For an armed post, confirm the officer holds an active Level III commission.
A lapsed or missing license is your liability and insurance problem as the client, not just the company’s.

Texas officer levels, in plain terms
Texas licenses security officers by level, and the level should match your post.
- Level II, non-commissioned: unarmed officers. A state training course and test are required.
- Level III, commissioned: armed officers. A minimum of 45 hours of training plus firearm proficiency, and armed officers requalify with 6 hours of continuing education at each two-year renewal.
- Level IV, personal protection: close protection, with an added 15-hour minimum on top of Level III. We do not staff this.
Ask which level a company will post at your site, and for armed coverage, ask to confirm the individual officer’s Level III commission. Both officer types work inside the same legal limits, covered next.

What a Texas security officer can and cannot legally do
A licensed security officer in Texas has the authority of a private citizen, not the powers of a police officer. What you pay for is an officer trained to use that limited authority correctly and to document it, so a stopped incident holds up afterward.
Under Texas law, any person, including a security officer, may make a warrantless arrest only when a felony or an offense against the public peace happens in their presence or view (Code of Criminal Procedure Article 14.01). For theft, Texas also lets any person recover stolen property and hold the suspect when there’s reasonable ground to believe the property was stolen, as long as the seizure is made openly and handled without delay (Article 18.16). A detained person is turned over to police promptly. A security officer does not file charges, transport, or jail anyone, and force is limited to what’s reasonable under the Texas Penal Code.
Carrying a firearm does not widen that authority. A Level III commissioned officer has the same arrest limits as an unarmed officer. The difference is deterrence and the response option on a high-risk post, not extra legal power. This matters to you because an officer who oversteps creates liability for the property owner, not only for the company. Training, clear post orders, and a written record are what keep a stop defensible.
Armed or unarmed: which your site needs
Most commercial posts are unarmed, and that’s the right call more often than not. Unarmed officers handle deterrence, access control, visitor checks, and observe-and-report work at construction sites, warehouses, vacant buildings, offices, and retail. The risk at those sites is theft, trespass, and vandalism, not armed confrontation.
Armed officers make sense when the site has cash on hand, high-value or easily resold assets, a history of violent incidents, or a specific named threat. Armed coverage costs more per hour, so many sites run unarmed patrol with a clear escalation plan instead. A company that pushes armed officers for every post is selling, not assessing. For most Houston commercial sites the honest answer is unarmed deterrence with documentation, and armed only where the risk profile calls for it.
Proof beats promises: how to know the patrols actually happen
The gap between a real security service and a drive-by is documentation. Ask any company how you’ll know an officer was on site and doing the work. The answer should be specific.
At Reliable Guard & Patrol Service, every patrol is GPS-tracked with a guard-tour system, rounds are documented, incidents are written up as reports the client receives, and supervisors run check-ins. You see the activity, not a promise. That record is the point. It’s what holds up with an insurer or in a dispute later.
This is what stopping a loss looks like. The entries below come from our patrol logs, with client names and addresses removed.
- Construction site. A pickup circled the site around 2 a.m., then stopped near a gated entrance while the occupants studied the access points. The officer switched on the patrol vehicle’s emergency lights and moved toward the gate. The truck left. He logged the vehicle description and notified site management. No property lost.
- Construction site. Two people carried materials toward the perimeter fence in an unlit corner of the lot. The officer lit the area with a spotlight and gave a verbal challenge. Both dropped the materials and ran. An inventory check came back complete.
- Construction site. On a scheduled round, the officer found a storage container forced open and someone pulling out rolls of copper wire. He called police, kept visual contact from a safe distance, and fed updates to dispatch. Responding officers made an arrest. The copper went back to site management.
- Vacant building. Two people were prying at a boarded rear window. 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.
- Distribution warehouse. After hours, an unauthorized vehicle sat near the loading docks while someone 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 found no forced entry and nothing missing.
Every one of these was GPS-logged and written up as an incident report the client received. Cameras record what already happened. A documented officer on site is what keeps it from finishing.
The 6-point officer standard behind every post
Guard reliability is the thing clients worry about most, so here’s the bar every officer clears before deployment. No officer works a post until all six are done.
- DPS license verification. Active Texas DPS registration confirmed for the level the post requires.
- Fingerprint background check. Full criminal screening, with fingerprint-based checks consistent with state requirements.
- Drug testing. Pre-assignment, armed or unarmed, no exceptions.
- Interview to standard. An in-person interview against conduct and presentation standards, not just a license check.
- Verified references. References contacted and confirmed. We verify history, we don’t assume it.
- Recurring training. Unarmed officers complete Level II training; armed officers requalify on firearm proficiency and complete 6 hours of continuing education at each two-year renewal.
Turnover runs high across the contract-security industry, which is exactly why the checklist is fixed and applied the same way to every officer, on every site.
Who we’re not the right fit for
We only do commercial security, and being clear about that saves everyone time. We staff two officer types, armed and unarmed, across construction sites, warehouses, buildings, vacant properties, retail and shopping centers, and similar commercial posts.
We do not take residential or HOA work, and we do not staff event security, K-9, fire watch, alarm response, or parking enforcement. If that’s what you need, a company built for it will serve you better. Commercial posts are the whole business here, which is why our officers know them.
Frequently Asked Questions
Do you require a long-term contract?
No. Terms are weekly, month-to-month, short-term, or long-term, set to the job. No year-long signature required.
How fast can you start?
In most cases the same day. First call, free proposal, a site assessment when the post needs it, then deployment.
Are you licensed, and how do I verify it?
Yes, Texas DPS license B07315701. Search “Reliable Guard & Patrol Service” or that number on the Texas TOPS public portal and confirm the status is active.
What’s the difference between armed and unarmed officers?
Unarmed officers handle deterrence, access control, and observe-and-report. Armed Level III officers add a firearm for higher-risk or cash-handling posts. Both work inside the same citizen-authority limits.
Do you offer event security, fire watch, K-9, or residential service?
No. We handle commercial posts only, armed and unarmed.
Are your officers background-checked?
Yes. Fingerprint background check, drug testing, license verification, an interview to standard, and verified references, all before deployment.
Do you have Spanish-speaking officers?
Yes. Bilingual English and Spanish officers work across the metro, which helps most on overnight coverage.
How do you prove the patrols actually happen?
GPS guard-tour tracking, documented rounds, written incident reports you receive, and supervisor check-ins. You see the activity, not a promise.
