Penetration Testing in Chelsea, MI
Manual, exploit-driven security testing for organizations in Chelsea. Fixed price, audit-ready reports mapped to ISO 27001, and a free remediation retest.
Why a scan is not a penetration test
CyberFortify runs manual web, API, network and cloud penetration tests for Chelsea organizations, with findings mapped to ISO 27001 and the other frameworks Michigan businesses answer to.
The question that matters is not whether you have weaknesses. It is which of them a motivated attacker could string together, and how far. Organizations in Chelsea, part of Washtenaw County, operate within Michigan’s economy of automotive and mobility, advanced manufacturing and healthcare, and the systems that run that work — customer-facing applications, the APIs beneath them and the networks they sit on — are exactly what CyberFortify is engaged to test.
The organizations that call us in Chelsea are rarely testing because they want to. They are testing because an enterprise customer sent a security questionnaire, an auditor asked for evidence, or a cyber-insurance renewal now requires it. In every case the useful answer is the same: a manual test that produces findings an engineer can fix and an assessor can accept.
The threats facing Chelsea organizations
Risk in Michigan looks different by industry. For the sectors that anchor Chelsea, this is what attackers target and what our testing is built to find.
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 Chelsea
You rarely need all of these at once — we scope to the systems where a breach would hurt and start there.
Web Application Penetration Testing
Authenticated testing that finds what an attacker with a valid login could reach.
API Penetration Testing
The BOLA, token-lifetime and rate-limit flaws that break APIs in production.
Network Penetration Testing
External perimeter and internal Active Directory, tested the way an intruder moves.
OT & ICS Penetration Testing
Where a compromised business network reaches equipment that moves the physical world.
Cloud Penetration Testing
How far a single leaked key or workload gets in your cloud tenant.
Mobile Application Penetration Testing
Local storage, certificate pinning and the API behind the app.
Evidence for the frameworks Michigan businesses answer to
These are the frameworks that bite hardest for Chelsea businesses, given Michigan’s automotive and mobility, advanced manufacturing and healthcare. We scope one test to satisfy all of them at once.
How a Chelsea 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 Chelsea 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 Chelsea engineer can fix them and an auditor can accept them. Fixed price, same-day critical escalation, retest included.
Penetration testing in Chelsea, answered
Is testing done on-site in Chelsea or remotely?
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.
What should a Chelsea company budget for a test?
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?
That is what the report is built for. Findings come with reproduction, CVSS scores and an explicit mapping to the control they defeat — commonly ISO 27001 for Michigan organizations — so your auditor can accept them without translation.
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 Chelsea 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 Chelsea companies selling into larger enterprises, a current test plus a completed questionnaire is usually what unblocks the deal.
How quickly can you begin in Chelsea?
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.
