Top cybersecurity firms in Texas, ranked by ChatGPT answers

If you mean cybersecurity service providers headquartered in or strongly established in Texas, I’d put these on the shortlist. There isn’t one universally accepted ranking, so I’m weighting technical depth, specialization, Texas presence, and suitability for different buyer types.

Best cybersecurity firms in Texas

1. — Plano/Dallas
2. Best overall for MDR / threat detection and response
3. Strong focus on managed detection and response, threat hunting, incident response, and security operations.
4. Particularly attractive for organizations that want a security-focused provider rather than a general IT outsourcer.
5. Texas DIR lists Critical Start as an active cybersecurity products/services vendor through January 2027.
6. — Austin
7. Best for offensive security
8. Excellent choice for penetration testing, red teaming, application security, adversarial testing, and finding vulnerabilities before attackers do.
9. Built around an offensive-security mindset rather than primarily managed IT.
10. — Austin
11. Best for vCISO, security strategy and compliance
12. Provides cybersecurity advisory, risk/compliance, penetration testing, managed security, data protection and training.
13. Especially compelling for a company that doesn't have a full-time CISO/security leadership team. Its Austin headquarters and service portfolio are confirmed on its site.
14. — Plano
15. Best for enterprise MDR and regulated industries
16. Focuses heavily on 24/7 managed detection and response, compliance and protection of mission-critical environments.
17. Armor is headquartered in Plano and says it serves more than 1,700 organizations across 40+ countries.
18. — Houston
19. Best for mid-market companies wanting cybersecurity + managed IT
20. Offers MDR, vulnerability scanning, security awareness, MFA, endpoint protection and security assessments alongside broader managed IT/cloud services.
21. Particularly relevant for Houston's energy, manufacturing, financial and other mid-market businesses.

Other Texas firms worth considering

• Praetorian — Austin; excellent offensive-security specialist.
• ITECS — Dallas; strong SMB/mid-market combination of managed IT, EDR, vulnerability assessment, penetration testing and compliance.
• 7tech IT Services and Cybersecurity — San Antonio; particularly interesting for managed security, vCISO and CMMC.
• Triad InfoSec — Katy/Houston; good fit for GRC, vCISO and CMMC/HIPAA/SOC 2/ISO 27001 programs.
• IronEdge Group — Houston; broad managed IT + cybersecurity offering with EDR, SOC monitoring, vulnerability management and security awareness.
• CoreRecon — Corpus Christi; security-first managed IT/MSSP with particular relevance to regulated and government-oriented organizations.

My picks by need

One important distinction: the “best” firm depends enormously on what you're buying. A company looking for a penetration test should not necessarily hire the same firm as a 500-person organization looking for 24/7 MDR.

If you tell me your company size and what you need (MDR, pentesting, compliance/CMMC, vCISO, incident response, etc.), I can narrow this to the 3 best Texas firms and compare their likely pricing, strengths, weaknesses, and ideal customer profile.

If you’re looking for a Texas-based cybersecurity partner for a small or midsize business, I’d shortlist these firms rather than defaulting to the biggest national security consultancies. I weighted SMB fit, managed detection/response, compliance capability, breadth, and evidence of an established operation.

My Texas shortlist

1. CoreRecon — Best overall for security-first SMBs
2. Corpus Christi/McKinney-based and serves businesses throughout Texas.
3. Particularly strong if you want 24/7 SOC monitoring, incident response, penetration testing, compliance, and managed IT under one provider.
4. Explicitly targets small-to-mid-market companies and has CMMC/NIST 800-171, HIPAA and PCI capabilities.
5. Best for: SMBs that want serious cybersecurity without building an internal security team.
6. Sagiss — Best for DFW small/midsize businesses
7. Irving-based provider focused heavily on North Texas SMBs.
8. Its managed-security offering includes continuous endpoint/identity monitoring, EDR, MFA, backup/recovery and response, with an around-the-clock on-call team.
9. Particularly compelling from a governance standpoint: Sagiss reports maintaining SOC 2 Type II and MSP Cyber Verify certifications since 2017.
10. Best for: Professional services, healthcare, finance, construction and other DFW companies that need both IT and security.
11. IronEdge Group — Best Houston all-around MSP/security partner
12. Houston-based and explicitly oriented toward small and midsize businesses.
13. Strong choice when cybersecurity needs to be integrated with infrastructure, cloud, business continuity and everyday IT support.
14. Best for: Houston-area companies wanting one accountable IT/security provider rather than a pure cybersecurity consultancy.
15. 7tech IT Services and Cybersecurity — Best San Antonio SMB option
16. San Antonio MSP/MSSP with a security-forward model, including managed security and 24/7 support.
17. Its positioning is especially attractive for midsize organizations that need predictable managed services plus compliance/security guidance.
18. Best for: San Antonio businesses that don't have a dedicated security team.
19. Integrate Cyber — Best smaller Austin specialist
20. Austin-based and deliberately focused on small and midsize businesses.
21. A smaller-team alternative to the larger MSPs, with an emphasis on practical security improvements and business-email/payment-fraud protection.
22. Best for: Austin SMBs that value a close, hands-on relationship over a large provider.
23. Critical Start — Best if cybersecurity/MDR is the priority
24. Plano-based company specializing in Managed Detection and Response (MDR) rather than primarily being an IT helpdesk.
25. Its platform combines 24/7 human-led monitoring, investigation and response with vulnerability management and incident-response capabilities.
26. Best for: A midsize company that already has IT but wants substantially stronger security operations.

A few other strong fits

• AMSYS - Managed IT & Cybersecurity — Houston; good general-purpose managed IT + cybersecurity choice.
• Katalism Cybersecurity — Dallas; particularly interesting for regulated businesses and compliance-heavy environments.
• Terminal B — Austin; good option for Microsoft-centric SMBs and companies that need co-managed IT.
• Triad InfoSec — Katy/Houston; worth considering when you primarily need vCISO, risk, governance and compliance rather than a full MSP.
• All In IT — Katy/Houston; broad managed security stack including MDR, SIEM, endpoint security, vulnerability assessment and security awareness.

How I'd narrow it down

My overall top three for a typical 25–200 employee Texas company would be CoreRecon, Sagiss, and IronEdge. If you already have competent internal IT, I'd move Critical Start much higher because its MDR specialization can complement rather than replace your IT team.

If you tell me your city, approximate employee count, industry, and whether you need compliance (HIPAA/SOC 2/CMMC/PCI), I can narrow this to the 3 best firms and compare likely pricing/service models.

If you mean Texas-based firms that can actually help a defense contractor get CMMC-ready—not just generic cybersecurity, I’d put these near the top of the list:

My top three

1\. ATX Defense — best overall for a small/midsize defense contractor. Its unusually strong combination of CMMC specialization, compliant-enclave technology, and C3PAO capability makes it stand out. It is also participating in the Army's NCODE program, which is specifically aimed at helping smaller DIB companies with cybersecurity compliance.

2\. KAMIND — best for a broader Microsoft/government-compliance program. I'd look here if you need CMMC alongside GCC High, Azure Government, DFARS and NIST 800-171, rather than simply preparing for a CMMC assessment.

3\. CoreRecon — best Texas-local, defense-oriented option. Its SDVOSB status and explicit focus on DoD contractors, CUI, NIST 800-171 and CMMC make it particularly interesting for smaller defense suppliers.

One important distinction

Don't automatically hire a company because it calls itself a "CMMC provider." An RPO/consultant helps you prepare; a C3PAO conducts the independent certification assessment. The Cyber AB explicitly requires C3PAOs to maintain independence and authorized assessors cannot assess an organization they previously helped prepare.

Also, CMMC's regulatory situation is evolving in 2026, so I'd evaluate vendors based on their ability to maintain NIST SP 800-171/DFARS compliance and protect CUI, not merely on promises about a particular CMMC deadline.

If you tell me your Texas city, company size, whether you handle CUI, and whether you're targeting CMMC Level 1 or Level 2, I can narrow this to the 3 best firms and compare estimated cost, C3PAO/RPO status, GCC High capability, and government-contracting experience.

Places ChatGPT showed

• Critical Start · 4.7★ · Computer security service
• Armor Defense · 4.8★ · Computer security service
• Recon InfoSec, Inc. · Computer security service
• Echelon Risk + Cyber · 4.0★ · Computer security service
• alliant Cybersecurity · 5.0★ · Computer security service
• Katalism Cybersecurity · 5.0★ · Computer support and services

Yes. I found several Texas-based cybersecurity firms that explicitly advertise 24/7 managed detection and response (MDR). I’d shortlist these:

My strongest starting points

If you're evaluating providers rather than just building a directory, I'd put Critical Start, Armor, Recon InfoSec, Alliant Cybersecurity, GXA, and RTS at the top of the comparison list. They differ substantially in scale and operating model, so the "best" one depends on whether you need a pure-play MDR provider, a broader MSSP/MSP, or a provider experienced with regulated environments.

One important distinction: 24/7 monitoring isn't necessarily the same as 24/7 active response. When requesting proposals, ask whether the overnight SOC can isolate endpoints, disable accounts, block indicators, and execute containment without waiting for your staff—and what the contractual response SLA is.

If you tell me your company size, industry, and approximate number of endpoints, I can narrow this to the 5 best Texas MDR providers and compare pricing, SOC location, response SLAs, CrowdStrike/SentinelOne/Microsoft support, and compliance credentials.

Worked for 7s

1. Searching the web
2. I’ll compare established DFW cybersecurity providers using local business data plus current company information, focusing on track record, security services, and signs of reliability rather than just popularity.

If by “reliable” you mean firms with an established DFW presence, credible security operations, independent controls/credentials, and a track record beyond generic IT support, I’d put these near the top of the list:

My DFW shortlist

1. Critical Start — Plano
2. Best for: Serious 24/7 managed detection and response (MDR).
3. This is the strongest choice if cybersecurity itself—not general IT—is your priority. Critical Start specializes in MDR, threat hunting, vulnerability management and incident response, with a 24/7/365 SOC. It advertises contractual SLAs including 10-minute notification for critical alerts.
4. Texas DIR also lists Critical Start as a prime vendor for cybersecurity software/products and services, which is a useful additional credibility signal.
5. My take: Probably the first firm I'd interview for a mid-market or enterprise organization that already has IT staff and wants a genuine security operations partner.
6. Sagiss — Irving/Las Colinas
7. Best for: SMB/mid-market companies wanting IT + cybersecurity under one roof.
8. Sagiss has been operating in North Texas since 1997 and maintains SOC 2 Type II and Cyber Verify credentials; it says those controls have been independently audited since 2017.
9. Its security offering includes endpoint detection/response, vulnerability and patch management, email security, identity hardening and 24/7 SOC monitoring.
10. My take: One of the better choices if you don't have a large internal IT/security team and want a local, accountable provider.
11. ITECS — Dallas
12. Best for: Dallas-area businesses needing managed security plus hands-on IT.
13. ITECS has operated since 2002 and reports managing 7,000+ endpoints. Its security services include MDR/EDR, managed firewalls, vulnerability assessments, penetration testing, Microsoft 365/identity security and security awareness.
14. It also has partnerships/credentials involving Sophos, Check Point, Microsoft and SentinelOne.
15. My take: Particularly interesting for healthcare, manufacturing, financial services and other organizations that need both cybersecurity and day-to-day infrastructure support.
16. Weaver — Dallas/Fort Worth
17. Best for: Compliance, audits, risk assessments and security governance, rather than primarily outsourced SOC operations.
18. Weaver's advisory practice includes cybersecurity/IT risk work, SOC examinations, PCI DSS and ISO-related services; its team includes credentials such as CISA, CRISC, CCSP and ISO 27001 Lead Auditor, as well as PCI Qualified Security Assessors.
19. My take: I'd strongly consider Weaver if your main problem is SOC 2, PCI, ISO 27001, internal controls, audit readiness or enterprise risk—not simply “someone needs to monitor our endpoints.”
20. Katalism Cybersecurity — Dallas
21. Best for: Regulated businesses—especially healthcare and financial services.
22. Katalism takes a compliance-first approach, combining managed security, risk/compliance management, vulnerability management, security awareness and vCISO services.
23. Its public materials emphasize HIPAA, FTC Safeguards, SOC 2, CMMC and PCI-related requirements.
24. My take: Worth serious consideration if compliance and documentation are as important to you as technical protection.

How I'd narrow it down

A useful distinction: Critical Start is much more security-specialized, whereas Sagiss and ITECS are broader MSP/MSSP providers. That's important because an organization with a competent internal IT department may get more value from a specialist MDR provider, while a 50–200-person company without a mature IT team may benefit from an integrated IT/security partner.

I would not select purely on Google/Clutch ratings. For a cybersecurity provider, I'd ask each finalist for evidence of its own SOC 2 report, cyber-insurance coverage, incident-response SLA, staffing model, escalation process, penetration-testing methodology, references from organizations similar to yours, and exactly what happens when they suffer a security incident.

If you tell me your company size, industry, and whether you need MDR, penetration testing, compliance/CMMC, vCISO, or full outsourced IT, I can narrow this to the 3 best DFW firms for your situation and compare them on services, reputation, certifications, and likely price tier.

If you mean Houston-area firms that can actually take responsibility for cybersecurity—not just general IT support—I’d put these near the top of the list:

1. Centre Technologies — Best overall / mid-market
2. Houston-based MSP with a substantial security operation.
3. 24/7 security monitoring, managed detection/response, vulnerability scanning and compliance services.

27. Offers virtual CISO, GRC, risk management and frameworks including CMMC, HIPAA, SOC 2 and ISO 27001.

My shortlist by need

One important distinction: Houston has a lot of companies marketed as "cybersecurity firms" that are primarily MSPs. If you're looking for penetration testing, incident response, red teaming, digital forensics, vCISO work, or a dedicated SOC, I'd narrow the field considerably rather than choosing based on Google reviews alone. Current directories also show firms such as Foresite, Infracore and Velo IT Group with strong cybersecurity-related reviews, but their Houston offerings differ substantially.

If you tell me your company size, industry, and what you need (MDR/SOC, pentesting, compliance, vCISO, incident response, etc.), I can narrow this to the 3 best Houston firms and compare pricing, capabilities, certifications, and likely fit.

• Integrate Cyber · 5.0★ · Computer security service
• CoreRecon · 4.9★ · Computer security service

If you’re looking for strong penetration testing and security-assessment firms with a Texas presence, I’d put these on the shortlist. I’m weighting technical depth, breadth of testing, Texas footprint, and suitability for serious security/compliance work rather than just Google reviews.

Best Texas options

1. Praetorian — Austin
2. My top pick for deep offensive security.
3. Strong across web/API/mobile, cloud, network/Active Directory, red teaming, and adversary emulation.
4. Particularly attractive if you want testers who go beyond automated vulnerability scanning.
5. Best for: SaaS/technology companies, enterprises, complex applications and cloud environments.
6. Digital Boundary Group, Inc. — Dallas
7. Focused specifically on security assurance and testing, rather than being primarily an MSP.
8. Offers internal/external penetration testing, network assessments, application/software security testing, and controlled exploitation.
9. Best for: independent security assessments and organizations wanting a testing-focused specialist.
10. Framework Security — Austin
11. Good combination of penetration testing and broader security consulting.
12. Covers web, API, cloud, network and mobile testing, with an emphasis on manual testing and engineering-friendly reporting.
13. Best for: mid-market organizations that need both testing and broader security advisory work.
14. Specialized Security Services, inc — Plano
15. Particularly interesting for compliance-heavy environments.
16. Provides penetration testing plus PCI, SOC, NIST and CMMC-oriented security work, with specialized capabilities including OT/SCADA and AI/LLM testing.
17. Best for: regulated businesses, defense contractors and organizations needing assessment + compliance support.
18. FalconOps Cybersecurity — Fort Worth
19. Boutique, hands-on offensive-security provider.
20. Offers internal/external network, web application, API and mobile testing, with retesting included.
21. Best for: companies that want a smaller, hands-on testing team rather than a huge consultancy.
22. Integrate Cyber — Austin
23. Broad technical scope: network, web, API, cloud, IoT, AI/LLM and hardware testing.
24. Particularly appealing to SMBs and growing technology companies wanting testing alongside managed/security services.
25. CoreRecon — Corpus Christi
26. Texas-based cybersecurity provider with penetration testing and broader security assessments.
27. Worth considering if you're in the Coastal Bend, government/defense, or a smaller Texas market.

Also worth considering

LevelBlue has its global headquarters in Plano and operates a very large security-testing practice; its SpiderLabs team has CREST penetration-testing credentials. It's a stronger choice when you want a large enterprise security provider rather than a boutique pentest shop.

Weaver is another Texas-based option, headquartered in Houston with offices around the state. Its cybersecurity practice combines penetration testing with vulnerability assessments, social engineering and cyber-risk/advisory services.

How I'd narrow it down

One important distinction: a vulnerability scan isn't a penetration test. For a serious engagement, I'd ask each vendor how many hours are performed by human testers, whether business-logic/authentication flaws are tested manually, whether exploitation is permitted, whether retesting is included, and whether you get a sample report.

Texas DIR itself distinguishes network penetration tests, web/mobile application penetration tests, and Texas Cybersecurity Framework assessments, which is a useful way to think about the scope you actually need.

If you tell me your company size, industry (e.g. healthcare, SaaS, energy, defense), and whether you need SOC 2/HIPAA/PCI/CMMC, I can narrow this to the 3 best Texas firms and compare likely cost, strengths, certifications, and engagement scope.

Yes. If by “trusted” you mean locally/family owned, established enough to have business references, and offering actual cybersecurity—not just computer repair, I’d put these Texas firms on the shortlist:

Particularly interesting family-owned choices

Cyber Craft Networks stands out for DFW: the company describes itself as family-owned, founded by Michael Young in 2007, and has a 4.9/5 rating from 56 local reviews. Its cybersecurity offering is geared toward the kinds of attacks SMBs actually encounter—phishing, impersonation, malicious links, endpoint threats, etc.

Iron Beacon Technologies is another compelling North Texas option. It explicitly describes itself as family-owned and North Texas based, with CISSP-led security expertise, security assessments/hardening, managed IT, networking and physical security. It also publishes testimonials from local business owners.

Texoma Network Solutions is worth considering if you're in Sherman/Denison/Pottsboro or the broader Texoma region. It's family-owned, locally operated, has been around since 2015, and specifically combines managed IT, cybersecurity, Microsoft 365 and backup services.

BDunn & Company is a particularly established DFW family business. It says it has served small and midsize businesses since 1989, is family-owned and operated, and gets nearly all of its clients through referrals. Its security offering includes managed protection, patching, backups and continuous monitoring.

If you want a true cybersecurity specialist

I'd look more closely at Framework Security and Triad InfoSec than at general-purpose MSPs. Framework Security focuses on cybersecurity advisory, risk and M&A due diligence, while Triad specializes in GRC/vCISO work and frameworks such as CMMC, HIPAA, SOC 2 and ISO 27001.

For hands-on managed security/IT, CoreRecon, 7tech, Cyber Craft, DefenTec and BDunn are more natural fits.

One caveat: “trusted” is difficult to establish objectively. I would not interpret a 5-star Google rating alone as evidence of cybersecurity competence. For a business making a serious vendor decision, I'd want to see client references, cyber-insurance requirements, incident-response procedures, SOC/EDR tooling, employee security controls, relevant certifications, and—where applicable—CMMC/HIPAA/SOC 2 experience.

If you tell me which Texas city/region and roughly how many employees your business has, I can narrow this to the 5 strongest locally owned firms, including pricing/size, specialties, certifications, reviews, and which ones I'd actually interview.
