Penetration Testing in Phoenix, AZ
Greater Phoenix has become one of the most strategically important industrial regions in the United States: TSMC's fabs in north Phoenix, Intel's Ocotillo campus and Microchip in Chandler, onsemi in Scottsdale and the equipment, chemical and materials suppliers that follow them, the large operations and servicing centres of American Express, Wells Fargo, JPMorgan Chase, Bank of America and Charles Schwab, Banner Health, HonorHealth and Mayo Clinic Arizona, Honeywell Aerospace and the defence contractors of Mesa and the East Valley, utilities such as Arizona Public Service and Salt River Project, and the software and e-commerce companies of Tempe and Scottsdale around Arizona State University. HackersHub runs manual offensive security engagements scoped to what these organisations actually face: state-aligned collection against process and design IP, ransomware against health systems, fraud against high-volume financial operations, and the HIPAA, PCI DSS, CMMC, SOC 2 and Arizona breach-law evidence that regulators and customers expect.
The Phoenix and Arizona threat landscape
The Phoenix threat model changed when leading-edge chip manufacturing arrived. A semiconductor fab holds process recipes, yield data and tool configurations that represent years of engineering, and its suppliers hold pieces of the same knowledge with far weaker defences. State-aligned groups collect against that supply chain through engineering workstations, file-transfer services, vendor remote-support paths into fab tools, and the identity systems that link a supplier to its customer. The industry has responded with SEMI E187, the cybersecurity specification for fab equipment, and with IEC 62443 practices for the operational networks around the tools, and testing has to respect the reality that a disrupted tool can scrap wafers worth more than most IT systems. Health systems carry the clinical-ransomware risk that defines US healthcare, and Arizona has one of the clearest public lessons in how those intrusions start: in 2016 a Phoenix-headquartered health system disclosed that attackers had first entered through the payment-card systems of its food and beverage outlets and moved from there to servers holding patient and insurance data, a breach that ultimately affected millions of people and led in 2023 to a federal HIPAA settlement in which regulators cited long-term, pervasive non-compliance with the Security Rule. The lesson, that a low-priority network segment can be the route to the most sensitive data, still holds in Phoenix engagements today. The banking and card operations centres of the Valley process large volumes of customer data and payments, which makes them targets for account-takeover fraud, insider misuse and attacks on contact-centre and back-office workflows. Utilities and the defence base add OT and controlled-information obligations. Arizona's breach law requires notice to affected individuals within 45 days of determining a breach, and notice to the Attorney General and the national consumer reporting agencies when more than 1,000 people are affected. Engagements in Phoenix routinely uncover vendor remote-access paths into manufacturing networks, flat segments where payment, building or guest systems touch clinical or corporate servers, contact-centre tooling with excessive data access, and service accounts shared across operations sites.

Industries we routinely engage in Phoenix
The Valley's economy is unusually concentrated; these are the sectors that make up most of our Arizona work.
Semiconductors & fab supply chain
Chip manufacturers in north Phoenix and Chandler, and the equipment, chemical, gas and materials suppliers around them. Engineering-network and IP-protection assessments, vendor remote-support path testing, identity and file-transfer reviews between supplier and customer, and passive-first OT assessments of fab and facility networks. Reporting aligned to SEMI E187 for fab equipment and IEC 62443 for operational networks, with export-control-aware handling under EAR.
Banking, card & financial operations
Operations, servicing and technology centres of national banks, card issuers and brokerages across Phoenix, Tempe and Chandler. Internal network and Active Directory testing, contact-centre and back-office application testing, privileged-access and insider-misuse scenarios, and segmentation testing of payment environments. Evidence mapped to PCI DSS v4.0.1 Requirement 11.4, the GLBA Safeguards Rule and FFIEC examination expectations. Card-data scoping is explained at /insights/pci-dss-penetration-testing/.
Healthcare systems
Integrated health systems, academic medical centres, specialty hospitals and the revenue-cycle and health-tech vendors serving them. Evidence for the Security Rule evaluation in 45 CFR 164.308(a)(8), segmentation testing between clinical, medical-device, guest and commercial networks, identity-led internal testing, and ransomware-readiness assessments of backup and recovery infrastructure. See /insights/hipaa-penetration-testing/ for scope guidance.
Aerospace & defence
Avionics, propulsion and defence-electronics manufacturers in Phoenix, Mesa and the East Valley, and their subcontractors. Testing of the environment in scope for controlled unclassified information, engineering and PLM segmentation, supplier access review and red team operations scoped against state-aligned tradecraft. Evidence aligned to CMMC 2.0 Level 2, NIST SP 800-171 Rev. 3 and DFARS 252.204-7012, with ITAR-aware handling.
Utilities & energy
Electric and water utilities, solar developers and the operators of large generation assets in central Arizona. External attack-surface and corporate-network testing, IT to OT boundary assessments, and passive-first review of control-system networks under explicit rules of engagement. Reporting that supports NERC CIP obligations for bulk electric system assets and AWWA cybersecurity guidance for water utilities.
Software, e-commerce & fintech
Software, online retail, automotive e-commerce and fintech companies in Tempe, Scottsdale and downtown Phoenix. Manual web-application and API penetration testing, cloud-configuration review, mobile-application testing against OWASP MASVS v2 and account-takeover resilience testing. Reports mapped to SOC 2 Trust Services Criteria. Auditor expectations: /insights/soc-2-penetration-testing/.
Compliance frameworks we report against
Phoenix organisations answer to an unusually mixed set of overseers: bank examiners, HHS, the Department of Defense, grid regulators and semiconductor customers that write their own supplier security clauses. Reports are structured so that each of those audiences can locate its own evidence directly: a management summary, technical findings with reproduction steps and CVSS scores, an attack-path narrative, and a remediation table tagged by the frameworks below.
- Arizona data breach notification law (A.R.S. 18-551 and 18-552): notice to affected individuals within 45 days, and to the Attorney General and national consumer reporting agencies when more than 1,000 people are affected
- HIPAA 45 CFR 164.308(a)(8) evaluation, read together with the 2023 federal enforcement emphasis on enterprise-wide risk analysis
- PCI DSS v4.0.1 Requirement 11.4 internal, external and segmentation testing for card operations centres
- GLBA Safeguards Rule (16 CFR Part 314) and FFIEC examination expectations for banking operations
- CMMC 2.0 Level 2, NIST SP 800-171 Rev. 3 and DFARS 252.204-7012 for the defence industrial base
- SEMI E187 cybersecurity of fab equipment and IEC 62443 for industrial and operational networks
- NERC CIP reliability standards for bulk electric system assets
- SEC material-incident disclosure under 8-K Item 1.05 for listed manufacturers and lenders
- SOC 2 CC7.1 / CC7.4 for Tempe and Scottsdale software vendors
- OWASP MASVS v2 for banking and automotive-retail apps

Why Phoenix organisations choose HackersHub
Phoenix is one of the US markets where on-site work matters most: fabs, plants, hospitals, utilities and bank operations centres keep their most sensitive systems on internal networks. HackersHub plans for that. Testers travel from Amsterdam to Phoenix, Chandler, Tempe, Scottsdale and Mesa for internal, wireless, OT and physical windows, and for multi-site programmes vetted US delivery partners extend the team under our rules of engagement and engagement lead. External, application, API and cloud testing continues remotely from the Netherlands in parallel. HackersHub was founded in the Netherlands in 2015, has completed more than 2,500 engagements, does not have an office in Arizona or anywhere else in the US, and plans its full-scale US market entry for the first quarter of 2027. Dutch and European semiconductor-equipment suppliers find that useful: the same firm can test their engineering environments in the Eindhoven region and their Arizona service operations. Michael van Mameren (OSCP) leads delivery, OSCP is the minimum for every tester, OSWE and CREST holders are on the team, and a retest of medium-and-above findings within 90 days is included. Clients give the work 4.9/5 across 127 reviews.
