Best Penetration Testing Companies in Houston (2026)

I run operations at Uprite, and a few times a month somebody forwards me the same email. An insurer, a bank or a big customer wants proof of a recent penetration test, and the person who got it has no idea who to call. If that’s you, start with our page on penetration testing in Houston, which explains what the work involves. This page is about the next question. Who should actually do it?

I budgeted an afternoon. It ran long. When I asked Google, its AI answer named a firm I couldn’t find any Houston office for, and it called another one Houston-based even though that company’s own contact page lists Illinois and Mexico. Not great. So on 5 November 2026 I threw the AI answers out and we started over. We ran 5 Google searches, pulled the Houston map listings for cybersecurity firms, and went through the websites of 25 IT and security companies that show up for Houston, looking for an actual penetration testing page. Ten had one. One more had a section on a broader page. The rest just blog about it.

First, where we sit. We sell managed IT and security, and we also run penetration tests ourselves, quoted by scope. So yes, we’re on our own list. We finish first. I’d rather show you the math than ask you to trust it. You’ll see the hole in our score straight away, a zero for tester credentials, because our pages don’t name our testers or their certifications yet. Every re-run of the numbers is further down, including the ones where we lose.

How did we score Houston penetration testing companies?

Testing depth carries 30% of the score. That took some thought. It’s what you’re paying for. I’ve read a lot of reports. The range is enormous. Some firms run a scanner, export the results and send it over as a “penetration test.” Others spend a week chaining three small weaknesses into a path to your file server and hand you screenshots of every step. Both call it pen testing on their homepage. Before you sign, the only clue you get is what each firm is willing to write down about its method, its report and its retest, so that’s what I read.

Each firm had to clear 2 gates first. It needed a real Houston presence, meaning a street address on its own website or a Houston-area Google listing at a street address. And its own site had to sell penetration testing on a page or a named section, not just mention it in a blog post. Eight made it, plus us.

Reviews only get 8%. I did that on purpose. Testers don’t collect Google reviews the way a help desk does, because a client who just got told their network is wide open rarely runs off to leave five stars. Two of the nine ranked firms have no reviews at all and one has a single review. If I’d leaned on stars, the busiest managed IT shop would have won, and that says nothing about who’s good at breaking in.

The rules were blunt. They cut both ways. A certification only counted if the firm lists it for its own people. A retest only counted if it’s in writing. If something wasn’t on the firm’s own pages, it got zero, even when I suspected it was true. That cost several firms points. I say where.

Houston penetration testing companies at a glance

The 9 best penetration testing companies in Houston, ranked

1. Uprite Services, the test and the fixes from one team

Yes, we ranked ourselves first. I know how that looks. So here’s the math. Our Houston pen testing page lists the 6 kinds of test we run, external, internal, web apps, Microsoft 365 and cloud, phishing, and physical and wireless, and it says plainly that a person does the work, not a scanner. That’s most of our 8 out of 10 for testing depth. We lost the rest because the page cites NIST SP 800-115 as a definition rather than saying we follow it, and it never describes an executive summary.

Most points come from elsewhere. Our two Houston Google profiles have 75 reviews between them at a combined 4.72, 63 on Westheimer and 12 on Space Center Boulevard, and we’ve been at this since 1999. We publish a ballpark, typically several thousand dollars quoted by scope, which none of the other eight do. Our free network assessment gives you a device inventory and a ranked list of problems before anyone pays a tester. After the test, each finding goes to a named owner and we rescan after every fix. Ongoing vulnerability scanning comes with our MSSP Security Focus plan, from $40 per user per month.

Now the weak spot. Credentials scored zero. Our pages don’t name the people who run tests or list their certifications, and under my own rules that’s zero, same as four of the other firms. Our testing page also went live on 5 November, so it has no track record of its own. A rescan isn’t a full retest either. Ask what one costs. And alliant makes a point on its own page that I can’t argue with, which is that whoever runs your network shouldn’t be the one grading it. If we manage your IT and also test it, ask us how we keep the two apart.

Pick us if you want one team to scope the test, run it and fix what it finds. If you want a tester with no stake in your network at all, Texas Cyber Solutions or Weaver are the next calls.

2. Texas Cyber Solutions, the method on paper

I’ll admit I didn’t expect Texas Cyber Solutions to come this close. It’s the youngest firm here by a mile. The site says it has served Texas since 2024, and the domain was registered that November, so when I opened its Houston page I was braced for a brochure. Instead I got the most complete description of a test that anybody in town publishes.

It lists 6 kinds of work, external and internal networks, web apps and APIs, cloud, phishing and red teaming. It names NIST SP 800-115 for planning and OWASP for application testing. And there’s one line I’d frame if I could, where it says scanner results are not treated as confirmed findings. You’d be amazed how many reports I’ve seen that are a scanner export with a logo pasted on top. The page also says what you get at the end, an executive summary, the technical findings, remediation recommendations and a record of what was in scope, and that it’ll retest after you fix things. I can hold a vendor to that. Most pages don’t give me anything to hold.

David Taxer, the founder, has a real bio. He spoke at HouSecCon in 2024 about using open-source research to unravel a life insurance fraud ring. Not a pen test, sure. But that kind of digging is half of what a good tester does in the first week.

The gaps are obvious. I couldn’t find one certification listed for whoever does the testing, and the address stops at Houston and a zip code. The Google profile is a service-area listing with 6 reviews. They’ll tell you what to fix but they won’t fix it for you. And two years isn’t much. If I were buying, I’d ask for the tester’s résumé and a redacted sample report before signing anything.

3. Weaver, the certified bench

Weaver is the opposite story. It’s a big audit, tax and advisory firm, and its own site calls the Post Oak Parkway office its headquarters, three floors at the top of the building. You aren’t hiring a pen-test boutique here. You’re hiring the cyber group inside an accounting firm, and that comes with real upside and one catch.

The upside is people. Weaver’s cybersecurity page says its team holds the OSCP and GIAC Penetration Tester certifications, plus CEH, CISSP, CISM and a PCI Qualified Security Assessor credential, which is the deepest list of offensive and audit credentials published by any firm we scored in Houston this year. Trip Hillman, a partner in the cybersecurity services group, has his own page with GPEN and QSA among roughly nine certifications, 12-plus years of evaluating security for clients, and a sideline teaching security auditing classes. If you’ve got a PCI assessor or an audit committee to satisfy, I don’t know a stronger bench in town. Weaver also sits 28th on INSIDE Public Accounting’s Top 100 firms list.

The catch is the page. Pen testing gets one section of a long services page covering networks, web apps, APIs, wireless and phishing, and it never says how they test, what the report looks like or whether a retest is included. Their 3 Google reviews are on an accounting-firm listing, which tells me nothing about the cyber team, and Hillman’s page links to Dallas. Here’s the funny part, though. Shuffle the weights at random and Weaver finishes ahead of Texas Cyber Solutions far more often than not, which I get into further down. If you want auditors and testers under one engagement letter, call them first.

4. alliant Cybersecurity, the test with a scan attached

alliant sells what it calls a VAPT, which is a vulnerability assessment and a penetration test bought together. They’re at 3009 Post Oak Boulevard, Suite 1500, and they pitch themselves as a vendor-agnostic consultancy for mid-sized companies.

I liked two things. The first is that they name real offensive certifications for their engineers, GIAC Certified Penetration Tester, Web Application Penetration Tester and Exploit Researcher and Advanced Penetration Tester, plus GCIA and CEH. Those aren’t easy to get. The second is that dark web scans, social engineering and retesting come inside the bundle, so the follow-up isn’t a surprise invoice later. They also tie the work to the FTC Safeguards Rule, PCI, HIPAA, FISMA, NIST SP 800-171 and ISO 27001, which means the report should be easier to hand to an auditor, an insurer or a customer’s security questionnaire without rewriting it.

Then there’s a line on their page I keep thinking about. It says that unlike a managed services provider or internal IT, they give you an unbiased read of your situation. That’s us, exactly. I felt that one. It’s also fair. It’s why I tell clients to keep the tester and the team running their network apart, even when both work for us.

The deliverable held them back. I couldn’t tell from the page what the report contains, and the method is a short list of steps with no framework behind it. Google shows 2 reviews, the domain dates to 2018, and the only phone number I found is toll-free. A mid-sized company that wants the scan, the test and the retest priced as one project should put them on the list.

5. Red Trident, for plants and control rooms

Most of the firms here test office networks. Red Trident tests the gear that runs refineries, pipelines and power plants. It was founded in 2014, it’s on Park Ten Place in the Energy Corridor, and every page on its site is about industrial control systems and operational technology.

Its testing page was the second-best I read. Also the most practical. They prefer to be on site for live production, they keep remote work for external scope and follow-up, and they schedule active exploitation in windows agreed with shift supervisors so testing never competes with safety systems. They also say plainly that patching often isn’t possible on a control network, which anyone who has worked a plant floor already knows and most IT vendors forget. The report is described properly too, with strategic recommendations for people, process and technology and technical details on each finding, including steps to replicate. You send your fixes back and get a revised report showing which attack paths are closed. There’s no price. They do list what drives it, from the number of sites and network zones to the testing windows you can give them.

So why fifth? Zero Google reviews, no named testers and no certifications on the pages I read, although the site says its people have spoken at DEF CON, Black Hat and the SANS ICS Summit. And they’re the wrong call for a law office with a file server and Microsoft 365. If you run a Ship Channel terminal or a midstream operation, though, I can’t think of a more specific firm in Houston.

6. DYOPATH, the tester that keeps running

DYOPATH confused me at first. There’s a Houston Google listing on the Northwest Freeway with 5.0 stars from 11 reviews, and a Houston service page. But its own contact page lists an office in Oakbrook Terrace, Illinois, another in Monterrey, Mexico, and no Houston street address. One of Google’s AI answers calls it Houston-based. Its own site doesn’t. I scored the site.

What makes DYOPATH interesting is the pairing. There’s a human-led Penetration Assessment, where they name Nessus, WebInspect and Metasploit among their tools and promise a boardroom-quality report with technical detail for your IT people. Then there’s an autonomous penetration test that keeps probing web apps, networks, cloud and APIs between engagements and checks whether flaws are actually exploitable. If your environment changes every month, that second piece is worth asking about. They name HIPAA, PCI DSS, SOC 2, ISO 27001, NIST and CIS on their assessment page, and they made CRN’s MSP 500 Elite 150 list in 2024.

Credentials sank them. The pages say “certified penetration testing experts” and then don’t name a single certification or a single testing lead. Zero points. I’d also want to know how much of the price is the automated test and how much is a person spending a week inside my network. Those aren’t the same thing.

7. Techcess, the network-only option

Techcess CyberSecurity Group works out of 6110 Clarkson Lane in Spring Branch and mostly sells managed security, a 24/7 security operations center, endpoint protection and monthly vulnerability reports for small and mid-sized businesses. Testing is on request. Their page covers internal and external network tests and walks through the stages, from profiling a company’s people and gathering intelligence to vulnerability analysis, exploitation and post-exploitation, with both manual and automated testing.

That’s a decent outline. It stops at the network. I didn’t see web app, cloud or phishing tests, the report isn’t described, and no certifications or names appear. The page also keeps saying “the platform” does each step, which left me wondering how much is a person and how much is software. I’d ask. One Google review, a 2018 domain and a toll-free number round it out. If you already use Techcess for monitoring and your insurer wants a yearly network test, it’s a reasonable fit.

8. GB Tech, the old hand with a short page

GB Tech goes back to 1986, when Gale and Jean Burkett started it, and it built its name on NASA and aerospace work. It has offices on Space Park Drive near Clear Lake, on Saint James Place in Uptown and on Market Street in Galveston, and nobody else on this list can point to roots that run that deep into Houston.

The testing page is short. It talks about simulated attacks on networks and locations and stops there, with no test types, no method and no report. One bit of advice on it is genuinely good. They tell you to run a vulnerability assessment and fix what it finds before paying for a penetration test, so the tester spends time on the hard problems. I’d say the same. No Google reviews on the Uptown listing and no testers named put them eighth, just ahead of NGNSYS on the unrounded score.

9. NGNSYS, the strongest review count among the testers

NGNSYS lists 2200 Post Oak Boulevard, Suite 1000, and has a 5.0 Google rating across 24 reviews, the most of any firm here after us. Its Houston penetration testing page promises thorough evidence and detailed analysis of each issue. They also build software and run managed IT, so they can fix what they find, and right now there’s an offer of a free security scan with 25% off the first 12 months of service.

Past that, little to score. The page names no test types, no method, no report contents and no testers, and the company’s About page still reads like unfinished template copy. Lots of good firms have thin websites. Don’t write them off. Just ask for a sample report and the certifications of whoever will run your test.

Not sure yet whether you need a test or a scan? Our guide to penetration testing vs vulnerability scanning will help you work out which one you need first. The Houston guide to choosing a scan or a test adds Harris County context.

What should a Houston business expect from a penetration test?

The federal government’s own guide, NIST SP 800-115, splits security testing into planning, execution and post-execution, and I use it as a checklist when I read a proposal for a client. NIST’s control catalog, SP 800-53, keeps penetration testing and vulnerability scanning in separate controls, CA-8 and RA-5. Different jobs. Price them that way.

Sometimes it’s mandatory. The FTC’s Safeguards Rule, at 16 CFR 314.4(d)(2), tells covered financial businesses, a group that includes tax preparers, mortgage brokers and auto dealers, that without effective continuous monitoring they must run a penetration test every year and vulnerability assessments at least every six months. Take card payments and PCI DSS joins the party. Insurers ask too.

The risk is local. When we went through the Texas Attorney General’s data breach list we counted 73 notices from Houston-area organizations in the year to 21 September 2026. Of the 60 that gave both dates, the median gap between a breach starting and somebody noticing was 59 days, and two in three ran past a month. That gap is what a good test is supposed to shrink. Attackers mostly walk through known holes, which is why CISA keeps a running Known Exploited Vulnerabilities catalog of flaws already being used in the wild. Any tester should check you against it. That’s the floor.

And the price? We publish a ballpark, typically several thousand dollars, and none of the other eight firms publishes anything, so every real number starts with a scoping call. Red Trident and Texas Cyber Solutions at least explain what moves it, mostly how many systems, sites and applications are in scope and how much retesting you want. Our guide to what a penetration test costs in Houston covers that in detail. For the bigger security budget, our Houston cybersecurity cost guide breaks it down by the rules your industry answers to.

How do you choose a penetration testing company in Houston?

Who will actually run the test?

Get names and certifications. OSCP, GPEN, GWAPT and GXPN all make you prove it hands-on. CEH is broader and easier to earn. If a firm won’t say who’s testing, or hands the work to a subcontractor, find out before you sign, because the person on the résumé they showed you and the person inside your network on testing day aren’t always the same. Weaver and alliant list real offensive credentials. Seven of the nine, us included, list none on the pages I read.

What exactly is in scope?

An external test only looks at what the internet can see. An internal test assumes somebody’s already inside. Web apps, cloud accounts, phishing and plant-floor systems are each separate work with separate prices. A first test usually covers the outside, the inside or both. Write down what’s off limits too, and who gets the phone call if something breaks mid-test.

Can we see a sample report?

Any serious tester has a redacted one. Ask for it. You want an executive summary your leadership can read, technical findings with steps to reproduce them, and fixes ranked by risk. Texas Cyber Solutions and Red Trident describe their reports on their own sites. Everybody else, ask.

Is a retest included?

Without a retest you’re guessing whether your fixes worked. Texas Cyber Solutions, alliant and Red Trident put retesting in writing. For the rest, ask whether it’s included, how long you get to fix things first, and what it costs if it isn’t. After the first test, how often you should pen test in Houston depends on the rules you answer to.

Who fixes what the test finds?

Projects die here. The report shows up. It lists 40 findings. Nobody owns them. Some testers advise on fixes, some do the work, some leave it all to you. If your IT is outsourced, get your provider and the tester on the same kickoff call. A fix plan with owners and dates beats a thick report every time.

How sure are we about first place?

We don’t win them all. Drop testing depth completely and Weaver wins at 6.96, with us second. Drop tenure and Texas Cyber Solutions edges us, 6.89 to 6.83. Give every rival 3 extra credential points and 2 more for after-the-report support, and Texas Cyber Solutions leads 7.25 to 7.15. And if you read our own testing page at its strictest, we fall to 6.55, still first, or to 5.95 at the very harshest, which is second.

I kept the 30% because the testing is what you’re paying for, and a firm that explains its method in public is easier to hold accountable when something goes sideways. If a deep certified bench matters more to you than anything else, call Weaver.

Which firms didn’t make the list?

A few names pop up in Houston searches and AI answers but didn’t clear the gates. CustomIS has a Houston penetration testing page, but its headquarters is in Arlington and I found no Houston office. Redpoint Cybersecurity runs near-identical testing pages for Houston, Indianapolis, Chicago and Charlotte, with no Houston address or map listing. Broadleaf Group has a Houston testing page with a toll-free number and no Houston address I could find. Triad InfoSec in Katy, which has 16 strong reviews, is really a governance and compliance advisory firm. It lists penetration testing as one capability, but I couldn’t find a page dedicated to it.

Then there are the managed IT firms with great local reputations. IronEdge, Aldridge, Centre Technologies, Meriplex, Truewater, Cyber One, CITOC, Preactive and Xvand are all well regarded, and several show up in our ranking of Houston cybersecurity companies. None of them sells penetration testing on a page of its own. So none qualified. That’s not a knock. It’s a different job.

So who should you call?

Want the test, the fix list and the rescan from one team? That’s us. If you want the clearest written method and a promised retest from an independent tester, start with Texas Cyber Solutions. If you need certified testers and PCI or audit experience, Weaver is the safer pick, and under random weightings it beats Texas Cyber Solutions far more often than not. If your risk lives on a plant floor or in a control room, call Red Trident. If your systems change all the time, ask DYOPATH about pairing a human test with its automated one.

Not sure you need a test yet? Fair enough. A lot of the requests forwarded to me are really asking for a vulnerability scan, and a lot of businesses buying a test haven’t fixed what a scan would already find. Our cybersecurity services in Houston start with that groundwork.
