Penetration Testing in Cleveland, OH
Greater Cleveland combines one of the largest health economies in the United States with a deep industrial and financial base: Cleveland Clinic, University Hospitals and MetroHealth in medicine, KeyBank's headquarters downtown and Progressive in the eastern suburbs, Sherwin-Williams, Parker Hannifin, Eaton and Lincoln Electric in manufacturing, Case Western Reserve University and NASA's Glenn Research Center in research, and the Federal Reserve Bank of Cleveland supervising the district's banks. HackersHub runs offensive security engagements scoped to the threat model these organisations face: ransomware against hospitals and public bodies, identity attacks on banking and insurance platforms, intrusions that cross from the office into plant-floor operational technology, and the evidence that the Ohio Data Protection Act, HIPAA, GLBA and federal research and defence contracts now require.
The Cleveland and Ohio threat landscape
Cleveland has seen at first hand what a ransomware attack does to a public organisation. In June 2024 the City of Cleveland closed City Hall and its satellite offices after what it first described as a cyber incident, later confirmed as ransomware, and services such as building and housing permits and payments were disrupted for weeks while the city worked with federal investigators and the Ohio National Guard's cyber unit. The pattern matches what we see across the region: an initial foothold through phishing, an exposed remote-access service or a compromised supplier, followed by quiet movement through Active Directory until the attacker controls enough of the estate to encrypt it. Health systems are the most attractive target in the metro. Academic medical centres run thousands of connected devices, clinical applications with long upgrade cycles and research networks that must stay open to collaborators, and any outage is measured in patient care. Banks and insurers face a different pressure: account-takeover campaigns, help-desk social engineering aimed at resetting multi-factor authentication, and API abuse against customer and agent platforms. The manufacturing base adds a third pattern. Coatings, motion-control, electrical and welding manufacturers run plants where programmable logic controllers, historians and engineering workstations were connected to the business network for reporting and remote support, often without the segmentation an attacker would have to defeat. Ohio has built a distinctive legal incentive around this: the Ohio Data Protection Act gives organisations an affirmative defence in data-breach tort claims if they maintain a written cybersecurity programme that reasonably conforms to a recognised framework such as the NIST Cybersecurity Framework or ISO 27001. Engagements in Cleveland routinely uncover clinical and research segments reachable from the corporate network, help-desk processes that reset authenticators on a phone call, flat paths from engineering workstations to production controllers, and remote-access appliances left unpatched long after a public advisory.

Industries we routinely engage in Cleveland
Where Cleveland engagements concentrate, and the attack paths each sector keeps presenting.
Academic medical centres & hospital systems
University Circle's academic medical campus, the county public hospital system, children's and specialty hospitals, and the physician groups and digital-health vendors that connect to them. We map how far a phished clinician account travels: into the electronic health record, onto imaging and infusion segments, toward backup consoles. Findings are written so the security officer can file them as the risk-analysis and technical-evaluation evidence HIPAA expects, and so the privacy team knows which systems would trigger Ohio's 45-day resident notice. Scope and cadence are covered in our HIPAA guide at /insights/hipaa-penetration-testing/.
Regional banking & financial services
Regional and community banks, wealth managers, payment processors and the fintech platforms that partner with them. External and internal penetration tests, identity and privileged-access assessments, help-desk and social-engineering testing aimed at multi-factor reset abuse, and manual testing of online banking, treasury and partner APIs. Evidence mapped to the FFIEC IT Examination Handbook expectations, the GLBA Safeguards Rule, SEC Regulation S-P and PCI DSS v4.0.1 Requirement 11.4.
Insurance & insurtech
Personal-lines and commercial insurers, agencies and the claims, policy and agent platforms behind them. Manual web-application and API penetration testing of quote, claims and agent portals, account-takeover and fraud-path analysis, cloud-configuration review, and evidence aligned to Ohio's insurance data security law based on the NAIC Insurance Data Security Model Law, overseen by the Ohio Department of Insurance.
Coatings, industrial & advanced manufacturing
Coatings and chemicals producers, motion-control and fluid-power manufacturers, electrical equipment makers, welding and metals companies, and their supplier networks across northeast Ohio. OT and ICS segmentation testing aligned to IEC 62443, assessments of engineering workstations, historians and vendor remote access, and red team scenarios that test whether an intrusion in the office can reach the plant floor.
Research, aerospace & defence supply chain
A private research university, a NASA field centre and the aerospace, propulsion and materials suppliers that bid on federal work around them. Campus networks are built for openness, which is why we test where research enclaves actually begin and end, how single sign-on federates with partner institutions, and whether controlled unclassified information stays inside the boundary a CMMC assessor will draw. Supplier readiness for DFARS 7012 and a CMMC Level 2 assessment is a frequent driver.
Public sector, utilities & SaaS
City and county government, regional transit and water authorities, municipal power, and the healthtech and B2B software companies near University Circle and the Flats. For public bodies the question after June 2024 is blunt: how quickly could an intruder reach domain admin and the backups, and would anyone notice? For software vendors the question comes from enterprise buyers who want an independent test of tenant isolation and APIs before signing, usually alongside a SOC 2 report; our guide at /insights/soc-2-penetration-testing/ explains what auditors look for.
Compliance frameworks we report against
Northeast Ohio clients rarely answer to one regulator. A health system reports to HHS and its research arm to federal sponsors; a bank faces examiners and the SEC at once. We therefore write one report with an executive summary, evidence-backed findings scored with CVSS, an attack narrative and a prioritised fix list, then add a cross-reference table so each finding points to the Ohio, federal or contractual control it affects. A retest of medium and higher findings within 90 days is part of every engagement.
- Ohio Data Protection Act (Ohio Revised Code Chapter 1354): affirmative defence in data-breach tort claims for organisations whose written cybersecurity programme reasonably conforms to a recognised framework such as the NIST Cybersecurity Framework, ISO 27001 or the CIS Critical Security Controls
- Ohio data breach notification law (Ohio Revised Code 1349.19): notice to affected Ohio residents in the most expedient time possible and no later than 45 days after discovery
- Ohio Department of Insurance oversight under Ohio Revised Code Chapter 3965, the state's version of the NAIC data security model for licensees

Why Cleveland organisations choose HackersHub
Northeast Ohio buyers tend to ask two things first: who exactly will test, and where are they based. The answer is direct. HackersHub is an offensive security firm headquartered in Amsterdam, founded in the Netherlands in 2015, with more than 2,500 engagements behind it and no office, address or staff in Ohio. Work that can be done over the internet, such as external perimeter, web application, API, cloud and identity testing, runs from the Netherlands. Work that needs physical presence, such as internal networks, Active Directory, wireless, clinical floors, plants and building access, is carried out by our testers travelling to Cleveland and, where a scope needs extra hands, by vetted US delivery partners working to our methodology. The minimum certification on the team is OSCP; OSWE and CREST holders handle application and advanced work, and Michael van Mameren (OSCP) leads engagements. Testing follows PTES, the OWASP testing guides and NIST SP 800-115, and calls are booked in Eastern time. We serve US clients today and are preparing a full US market entry for Q1 2027, which is why 20 qualifying US companies can receive a complimentary penetration test beforehand. Clients score our work 4.9/5 over 127 reviews.
