Best Penetration Testing Companies in San Antonio (2026)

We searched “best penetration testing companies San Antonio” and a few close variants in early November. Most of the results were national top-ten lists written by the vendors on them, plus a few local pages with no scoring a buyer could check, and hardly any told a San Antonio buyer who actually keeps testers in the city. That was the gap. So we built a score and printed the math.

This is our website, and we sell penetration testing, which gives us a stake in the result, so every weight, every factor score and every re-run is published below for anyone to check, and a few of the re-runs put another firm in front of us, which is why we kept those rows in the table.

Why San Antonio Companies Ask for a Penetration Test

It usually starts with a request nobody planned for. A cyber insurance renewal adds a question. A bigger customer sends a security questionnaire with a line asking for the date of your last test. A defense prime wants evidence before it passes a contract down. Each one uses the same two words, and almost nobody defines them. Not so fast.

The federal guide helps. NIST Special Publication 800-115 treats penetration testing as authorized evaluators trying to defeat a system’s protections the way a real attacker would. That’s a person, working from a written scope. Scope is everything. A scan is software running down a list. It finds possibilities. Plenty of buyers pay for the first when the second would have answered the question, and our guide to penetration testing versus vulnerability scanning sorts out which is which before you sign anything.

Attackers don’t need to be clever. CISA keeps a public catalog of known exploited vulnerabilities, and the entries are flaws that already have names and patches. A tester’s job is to find the ones still sitting on your network. Plenty are.

San Antonio adds its own pressure. Joint Base San Antonio anchors a defense supply chain, so suppliers answer to contract clauses. Health systems and clinics hold patient charts. Those need protecting. Tax preparers and mortgage brokers fall under the FTC Safeguards Rule, and its testing requirement in 16 CFR 314.4 asks for continuous monitoring or an annual penetration test plus vulnerability assessments every six months. Anyone taking cards answers to PCI DSS, which wants a test each year too. The list keeps growing.

Hiring is the other route, and it’s expensive. Salaries tell the story. The Bureau of Labor Statistics counts 1,350 information security analysts in the San Antonio-New Braunfels metro for May 2025. Their median pay is $122,560 and their mean is $125,830, which makes that the closest government category to an in-house tester. Most small companies can’t carry a salary like that for one annual test, so they buy by the engagement, and that works fine as long as the scope is written down before the work starts.

Texas adds a deadline. A breach that touches 250 or more Texans has to be reported to the Texas Attorney General within 30 days, and that report goes faster when you already know what a tester found last spring.

If you’re still working out whether you need a test at all, begin with our cybersecurity risk assessment in San Antonio. It costs less and it tells you what to scope. Start there.

How We Ranked These San Antonio Penetration Testing Companies

Seven criteria, each scored from 0 to 10, make up the Proof Path Score once they are weighted. The evidence is all public, meaning each firm’s own testing pages, its team pages where they existed, and its Google listing where we could find one. Nobody paid to be here. No firm handed us numbers. Spot an error and we’ll correct the score along with the sentence.

We applied two gates first. The firm’s base had to be in the San Antonio metro, meaning a street address here, a listing here, or its own statement that it is based here. Its own site also had to sell penetration testing on a page or a labeled service section, because a blog post about testing proves nothing about who does the work. We checked twenty firms by name. Six cleared both gates. Six isn’t many. Fourteen did not, and the reasons are in a section below.

We fixed the weights before we scored anyone. No tuning afterward. Test depth carries the most because it’s the thing you’re buying. That seemed obvious. A firm with no Google record we could find earns zero on that criterion, which is a real cost, and we test it below. Tenure counts from the founding year a firm states, or from its domain registration when it states none.

Three things cost us. We publish no tester names or certifications, so we earn nothing on credentials. Our penetration testing page is written for Houston and says we perform the test ourselves, and we haven’t written a San Antonio version. And our SOC 2 report is a Type 1, which scores below a Type 2. Two criteria help us, since tenure gives us full marks because of a 1999 start and our Google record is strong at 4.9 across 43 reviews, which together lift our total well above where our testing page alone would put it.

Read that table twice. It matters. A buyer who cares most about the tester should call Sheepdog or Open Security before us. A buyer who wants a vendor with roots should call Computer Solutions or 7tech. And our lead rests partly on a test depth score we earned from a Houston page. Cut it hard enough and we lose first place. We say so.

A note on method. A score can only reflect what a firm publishes, so a firm that tests very well but writes three sentences about it loses out to one that documents a full process. We’d reward the documenters, though not everyone will. A quiet firm can still deserve a call. Quiet isn’t bad.

Google ratings are from Apify Google Maps pulls dated November 3, 2026. We could not run a fresh pull for this article, so treat those counts as early November figures. They may have moved. Each firm’s pages were read on November 12 and 13, 2026, and anything we couldn’t confirm is marked in the text. Look for the flags.

The 6 Best Penetration Testing Companies in San Antonio at a Glance

The 6 Best Penetration Testing Companies in San Antonio (2026)

1. Uprite Services, testing, scanning and a fix list from one firm

Uprite is a managed IT and security company. We opened in 1999 and serve Texas businesses from offices in Houston, Southeast Houston, San Antonio and Dallas. We employ about 42 people. The San Antonio office sits at 11831 Radium Street. Its Google profile reads 4.9 stars on 43 reviews, and it’s the only one we have in the metro, so no weaker profile pulls the average down.

Our testing page says plainly that we perform the test ourselves. We quote each one by scope as its own project, and a stand-alone test typically costs several thousand dollars. Four things move the quote, which are the number of internet-facing systems, whether the tester starts outside or inside, whether custom web apps are in scope, and whether a retest is in the price. The page lists six target types, which are external network, internal network, web apps, Microsoft 365 and cloud, phishing, and physical and wireless, and you can read it at penetration testing in Houston. We haven’t written a San Antonio version yet. That’s a gap.

• We scan first. Recurring vulnerability scans come with our security monitoring plan from $40 per user per month, so the known flaws get fixed before anyone bills test hours to find them.
• Our network assessment costs nothing. It’s read-only, and you keep the report whether or not you hire us.
• Findings are ranked by what an attacker could reach, handed to a named owner and tracked until someone closes them. After each fix we rescan and give you a written record for your insurer or customer.
• A 120-day satisfaction guarantee backs our managed plans.

The weak spots are real, and the score shows them. We publish no tester names and no certifications. That’s why we earn nothing on credentials. It stings. If we already run your IT, you should ask how the testing stays honest, because a provider grading its own homework deserves that question and you shouldn’t simply take our word that we’re fair about it. Our SOC 2 report is a Type 1 from 2023, which tests how controls are designed at one moment and not how they run over months. We’re headquartered in Houston, so we earn only part of the local presence credit. A retest isn’t promised in writing either, which is why we told you to ask about it above.

Recognition helped. Not by much. Channel Futures has named us to its MSP 501 list seven years running, most recently at No. 264 in 2026.

We fit a San Antonio company that has an insurer, regulator or customer asking for a test and wants one firm to scan, test and help close the findings. A software shop that needs deep application testing from a named senior engineer fits us less well. We’ll say so on the first call. Honesty saves time.

2. 7tech, the local firm that promises scheduled retests

7tech is headquartered at 2544 MacArthur View. Its Google listing shows 5.0 stars across 113 reviews, a record only Computer Solutions beats. That’s a strong record. Neal Juern started the company in 2012, and its testing page says it brings 13 years of experience and a 97.4% customer satisfaction rating.

The firm sells network penetration testing on a page of its own and says the tests are led by experts in its private US-based security operations center, covering internal, external and cloud layers and checking lateral movement and privilege escalation. A scan step uses automated and manual tools and produces an inventory mapped to compliance standards. Reporting comes as an executive summary and a plain-language debrief. The page says it schedules retests and tracks trends so you can confirm remediation worked.

Compliance is its strongest angle. The page shows it. The page names NIST, CMMC, HIPAA and the FTC Safeguards Rule, and it offers evidence packages for audits. That fits the manufacturers, nonprofits and defense suppliers the firm says it serves.

Points were lost in three places. The page names no testers and no certifications. It posts no price. That cost points. And two claims, that its tests are proven to reduce risk by 50% and that 80% of issues are resolved the same day, come with no source we could find, so we gave them no credit. At 14 years it’s also younger than three other firms on this list. Age isn’t everything.

7tech suits a company that wants a nearby firm with a security operations center and a written retest. It suits a buyer who wants a named tester or a posted price less well.

3. Open Security, senior operators and a continuous testing platform

Open Security says it was founded in 2016 and is headquartered in San Antonio. Its site shows no street address. That matters here. A business directory lists one in the 78253 ZIP code, which we mark [VERIFY], and we could not find a Google rating, so it earned nothing on that criterion. The firm is veteran-owned, its chief executive is a Marine Corps veteran, and it works with clients across the United States.

Its testing pages go further than any other firm’s here. It has separate pages for network testing, application and software pipeline testing, manufacturing and operational technology testing, and red, purple and ransomware exercises. The network page describes a five-step engagement that tests the internet edge, walks the inside from an agreed foothold, and delivers one risk-ranked story instead of two reports. It says senior operators do the testing, not junior analysts rerunning scanner output. It also promises to stay through retest on both sides of the perimeter.

The team is public. That helped. Matt Toussain is its chief information officer, a SANS instructor who authored the SANS SEC460 course. Bryce Zuccaro, a principal security engineer, co-instructed it and has served on the DEF CON Red Team Village. Those talks and bios earned credit even though the site lists no offensive certifications. The firm also runs Aludra, its own continuous testing platform, and says it responds in under four business hours. That’s quick.

The costs are a missing price, a missing Google record, a 2016 start and no street address on its own pages. Its industry pages lean toward healthcare, manufacturing, banking and critical infrastructure.

Open Security suits a manufacturer with plant systems, a software team that ships often, or any buyer who wants to meet the people who will do the testing. If a posted price decides it for you, look at the next firm.

4. Sheepdog Cyber Defense, a posted price and six named certifications

Sheepdog is a veteran-owned firm founded in 2022 and based in Bulverde and Spring Branch, in the Hill Country north of the city. It publishes no street address and no phone number, and we found no Google rating, so it earned little on local presence and nothing on Google. It passed our first gate on its own statement that it serves San Antonio from the Hill Country. That’s a thin pass.

What it publishes, it publishes clearly. Credit where due. The firm lists the certifications it holds, which are CRTO, PNPT, GWAPT, eCPPTv2, PWPA and CEH. It sells external, internal and web application tests, red teaming and physical site reviews. Web tests follow the OWASP Top 10, and the site says every finding is verified manually. Reports include proof of concept, steps to reproduce, CVSS ratings, evidence and an executive summary.

Price is where it leads. We checked every page. External testing starts at $2,500 for a small organization, internal from $3,500, a web application from $2,500 and red teaming from $15,000. The site gives timelines of one to three weeks for most tests, and it offers a retest that typically takes three to five days, and it names PCI DSS, HIPAA, SOC 2, NIST CSF and ISO 27001 as the standards its tests support.

It scored low because it is four years old, names no staff and gives no street address. Nobody on the team has a public bio. We looked. That’s the gap between a firm you can verify and a firm you have to take on faith.

Sheepdog suits a small company that wants a certified tester and a number it can budget before the first call. It fits a Hill Country or north Bexar County business especially well. It suits a buyer who needs a firm with a long public record less well.

5. Hi-Tex Solutions, testing next to a local managed IT firm

Hi-Tex has an office at 4040 Broadway and another in Selma. Its Google listing shows 4.9 stars across 40 reviews. The record is solid. The testing page says the firm has more than 20 years of experience and counts 65 clients. Those are its figures.

Its page lays out the work in plain terms. External testing looks at exposed services, firewall behavior, VPN access and cloud entry points. Internal testing checks segmentation and how far one stolen account can travel. An identity review covers Microsoft 365 and Entra ID permissions, and a hardening review covers firewall rules, switch configurations and wireless access, while the reporting is built so leadership, internal IT and compliance staff can each use it and the page names HIPAA and NIST.

The page says nothing about a retest and offers no price beyond a quote request. It names no testers or certifications. That limits trust. The recognition we found was thin as well. We checked.

Hi-Tex suits a company that already buys managed IT locally and wants the same relationship to cover testing. It suits a buyer who needs proof of the tester’s qualifications less well.

6. Computer Solutions, a San Antonio name with an identity-focused test plan

Computer Solutions is headquartered at 14410 Wurzbach Parkway and says it has served customers for more than 40 years. Its Google listing shows 5.0 stars across 116 reviews, the largest local record on this list. The firm holds cooperative purchasing contracts through OMNIA Partners, GSA and NCPA, which matters to public-sector buyers. That counts.

Its penetration testing page, dated May 29, 2026, lists five test types. They are external, an Active Directory password audit, a Microsoft Entra ID test, internal network and cloud. The process runs in five steps, from kickoff and a discovery meeting through tool deployment to the tests themselves and a readout, and the tests run in a set order that starts outside, moves to the password audit and Entra ID, and finishes inside the network. Remediation plans are written for IT, governance and executive readers.

Points were lost because the page doesn’t say the testing is manual, names no testers or frameworks, and posts no price. It also doesn’t mention a retest. That’s a common gap. The firm does point to ongoing monitoring and remediation services, which earned partial credit.

Computer Solutions suits a buyer who wants a long-established local firm, a Microsoft-heavy environment tested and a cooperative contract vehicle. It suits a buyer who wants named testers less well.

Firms We Checked That Didn’t Make the List

Fourteen firms failed a gate. That’s most of them. Some of these firms do strong work. Some are excellent. Missing a gate only means there’s no page a buyer can read.

Some firms advertise San Antonio without an office here. GuardsArm has a San Antonio testing page, but the only U.S. office it lists is in Austin. Plurilock’s San Antonio pages name no office. Broadleaf Group sells a rapid internal test and lists a Houston address. Infonaligy has a New Braunfels listing, but its San Antonio page names no test types. Texas Pen Testers announced a San Antonio expansion from a Dallas dateline.

Two firms we could not score. Here is why. Weaver, a Houston accounting and advisory firm, lists GPEN and OSCP among its credentials, but we couldn’t confirm a San Antonio office address. Fortra, which absorbed the San Antonio firm Digital Defense, has a San Antonio Google listing at 3.6 stars across 9 reviews, but its site returned an error to our reader, so we left it unscored. We’d rather say that.

The rest are managed IT firms whose sites sell testing as a blog post or not at all. SecureTech, Bridgehead IT and TechSage Solutions each have articles about penetration testing and no service page. IPSecure has no testing page. Aldridge sells assessments and vulnerability scans. Centre Technologies sells managed vulnerability scanning. IronEdge Group lists no testing service. Nothing to score. Any of them could pass in a later round if it publishes the page. The door stays open.

How to Choose a Penetration Testing Company in San Antonio

Begin with why you’re buying. Everything follows from that. An insurer’s form, a customer questionnaire and a contract clause want different things, and the paperwork you need decides the scope. Ask whoever is requiring the test what they will accept before you collect quotes.

Buyers here tend to sort into four groups.

• A small company answering an insurer or a customer should compare Sheepdog, Uprite and 7tech, because all three describe a defined scope and a report.
• A manufacturer with plant systems or a software team that ships weekly should call Open Security first.
• A public-sector or healthcare buyer with a local-vendor preference should call Computer Solutions or Hi-Tex.
• A company that already has a security team and wants a second opinion should ask for named testers and read their credentials.

Bring five questions to the first call.

• Who will do the testing, and can I see their certifications?
• Is a retest in the price, and is that written down?
• Which systems will you test, and which are off limits?
• What does the report contain, and can I see a sample with names removed?
• What happens if you find something serious at 11 p.m.?

Write the answers down and compare them side by side. Differences show up fast.

Order matters for cost. Inventory what you own, scan it, fix what turns up, and only then pay for a test, so the tester’s hours go to the harder problems and not to the unpatched firewall that a free inventory would have caught.

Our Verdict

On our own scoring, Uprite Services comes out first. We fit best when you want one firm to scan, test and help you close what the report finds. We earned that on our Google record, our tenure and our after-the-report work, and we lost points on credentials, on a testing page that is still written for Houston, and on a SOC 2 Type 1. Those losses are real. We aren’t hiding them. Our lead over 7tech is 0.70 points, and it disappears if you cut our test depth score to 5. Our lead is thin.

If you want to meet senior operators and test operational technology, call Open Security. If you want a certified tester and a posted price, call Sheepdog. If a long local record matters most, call 7tech or Computer Solutions. Whoever you hire, get the scope, the retest and the report format into the contract. Verbal promises fade.
