Penetration Testing in Plymouth, MI
Human-led penetration testing for Plymouth businesses and the systems they run on. Fixed price, audit-ready reports mapped to ISO 27001, and a free remediation retest.
What a penetration test is really for
CyberFortify runs manual web, API, network and cloud penetration tests for Plymouth organizations, with findings mapped to ISO 27001 and the other frameworks Michigan businesses answer to.
Security tooling tells you what is theoretically exposed. A penetration test tells you what a capable attacker would actually do with it. Organizations in Plymouth across Wayne County operate within Michigan’s economy of automotive and mobility, advanced manufacturing and healthcare, and the systems that run that work — the web apps, APIs, identity systems and cloud accounts that run day to day — are exactly what CyberFortify is engaged to test.
Businesses in Plymouth carry the same exposure as their larger peers elsewhere, often with leaner security teams. Broken access control, authorization logic that trusts the client, and segmentation that exists on a diagram but not in the routing table are the findings that recur — and the ones no scanner reports.
The threats facing Plymouth organizations
The threats that matter in Michigan track the work Plymouth organizations actually do — here is where compromise tends to start in the sectors that define the local economy.
Automotive and mobility
Automotive manufacturers, suppliers and dealer networks span plant-floor OT, connected-vehicle data and dealer systems holding customer finance information. ISO/SAE 21434 and UNECE R155 now set expectations for cybersecurity across the vehicle lifecycle and its supply chain.
We test the manufacturing environment and its IT boundary, the platforms and APIs handling connected-vehicle and customer data, and the dealer-facing systems where personal and financial information concentrates.
Manufacturing
Manufacturers increasingly run converged IT and operational-technology networks, where a phishing email that lands in the front office can end up on the plant floor. Downtime is measured in lost production, and ransomware operators know it — manufacturing is among the most-targeted sectors for exactly that reason.
We test the corporate network and the boundary between it and the OT environment, following the paths an attacker would use to move from email to ERP to the systems that control production, with safety and uptime treated as hard constraints.
Penetration testing services for Plymouth
Most engagements combine two or three of these, scoped to where a compromise would cost Plymouth the most.
Web Application Penetration Testing
Authenticated testing that finds what an attacker with a valid login could reach.
API Penetration Testing
Object-level authorization, token scope and mass assignment across your endpoints.
Network Penetration Testing
Perimeter exposure and internal domain compromise paths, mapped end to end.
OT & ICS Penetration Testing
IEC 62443-aligned assessment of the plant floor and its SCADA systems.
Cloud Penetration Testing
Over-broad IAM, exposed storage and escalation from one compromised workload.
Mobile Application Penetration Testing
iOS and Android against OWASP MASVS, client and backend both.
Evidence for the frameworks Michigan businesses answer to
Because Michigan’s economy runs on automotive and mobility, advanced manufacturing and healthcare, Plymouth organizations are most often held to these frameworks — a single engagement produces evidence for each.
How a Plymouth engagement runs
The same sequence every time, so the result is defensible.
Testing aligns to PTES and NIST SP 800-115, application work follows OWASP, and exploitation maps to MITRE ATT&CK. Automated tooling enumerates the surface; a named tester confirms every finding by hand.
Findings your team can fix and your auditor accepts
Every finding is reproducible, scored in context, and tied to the control it defeats.
The example alongside is illustrative — not from a client engagement — to show how each issue is documented and mapped to ISO 27001 and the standards Michigan organizations answer to.
| Ref | Finding | Severity | CVSS |
|---|---|---|---|
| F-01 | IDOR exposes cross-tenant records | Critical | 9.1 |
| F-02 | Over-privileged service account | High | 8.2 |
| F-03 | Session persists after reset | Medium | 5.4 |
| F-04 | Verbose error disclosure | Low | 3.1 |
What sets a Plymouth engagement with us apart
A scan-and-report vendor
Automated output rebadged as a test. Severities the tool assigned, findings you cannot reproduce, no real attempt at authorization logic or privilege escalation — and a report your assessor hands back. The retest is a new invoice.
CyberFortify
A named tester who works the target by hand, chains findings to prove real impact, and writes them so a Plymouth engineer can fix them and an auditor can accept them. Fixed price, same-day critical escalation, retest included.
Penetration testing in Plymouth, answered
Do you need to be on-site in Plymouth?
For the common cases, no. Anything reachable over the internet — web, API, cloud, external network — is tested remotely. On-site is reserved for internal, wireless and physical work, and we agree it and its cost during scoping.
How is pricing set for a Plymouth engagement?
There is no per-city rate; cost tracks the size of the engagement — how many apps, cloud accounts, hosts and roles are in scope. You get a fixed quote after scoping, usually the same hour, and it holds for the agreed work.
Will the report satisfy our auditor?
It is designed to. Each finding is reproducible, scored and tied to the control it breaks, which is what an assessor needs. For most Michigan businesses the relevant framework is ISO 27001, and we scope the engagement to it directly.
What do you focus on for Automotive organizations?
We test the manufacturing environment and its IT boundary, the platforms and APIs handling connected-vehicle and customer data, and the dealer-facing systems where personal and financial information concentrates. In a Plymouth engagement that usually starts with plant-floor ot exposure and works outward from there.
Can you sign our vendor security questionnaire?
Yes. We complete SIG, CAIQ and custom questionnaires and can join the vendor review call. For Plymouth companies selling into larger enterprises, a current test plus a completed questionnaire is usually what unblocks the deal.
How soon can a Plymouth engagement start?
Lead time is usually one to two weeks once scope is set, less if an audit or customer deadline is pressing. The scoping call is where we lock the price and the date.
