Penetration Testing in South Lyon, MI
Manual, exploit-driven security testing for organizations in South Lyon. 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 South Lyon organizations, with findings mapped to ISO 27001 and the other frameworks Michigan businesses answer to.
Knowing you have vulnerabilities is easy. Knowing which ones an attacker can actually exploit against you is the point of a real test. Organizations in South Lyon across Oakland County operate within Michigan’s economy of automotive and mobility, advanced manufacturing and healthcare, and the systems that run that work — customer portals, payment flows, internal networks and the cloud behind them — are exactly what CyberFortify is engaged to test.
When a South Lyon company is compromised, the entry point is rarely exotic. It is a reused password, an exposed admin panel, an API that trusts a client-supplied user id. A penetration test finds those the same way an attacker would — by trying, not by guessing from a report.
The threats facing South Lyon organizations
The threats that matter in Michigan track the work South Lyon 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 South Lyon
Most engagements combine two or three of these, scoped to where a compromise would cost South Lyon the most.
Web Application Penetration Testing
Every user role exercised for the authorization and logic flaws scanners miss.
API Penetration Testing
Object-level authorization, token scope and mass assignment across your endpoints.
Network Penetration Testing
Whether your segmentation holds once someone is already inside the network.
OT & ICS Penetration Testing
The IT/OT boundary, tested without putting operations at risk.
Cloud Penetration Testing
Configuration and identity review across AWS, Azure and Google Cloud.
Mobile Application Penetration Testing
Device-side controls and the server they are supposed to protect.
Evidence for the frameworks Michigan businesses answer to
Because Michigan’s economy runs on automotive and mobility, advanced manufacturing and healthcare, South Lyon organizations are most often held to these frameworks — a single engagement produces evidence for each.
How a South Lyon 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 South Lyon 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 South Lyon engineer can fix them and an auditor can accept them. Fixed price, same-day critical escalation, retest included.
Penetration testing in South Lyon, answered
Does the team have to travel to South Lyon?
Usually not. Web, API, cloud, mobile and external network testing is delivered remotely from our US-based team, which is how most South Lyon engagements run. Internal network, wireless and physical assessments are the cases where we come on-site, and travel is quoted up front.
What does a penetration test cost for a South Lyon business?
It depends on scope rather than where you are. We count applications, cloud accounts, hosts and distinct roles, then quote one fixed price after a short scoping call — typically within the hour, with no hourly meter afterward.
Will the report satisfy our auditor?
Yes. Every finding carries reproduction steps, CVSS v3.1 scoring and a control mapping, so an assessor can trace a requirement to the test that exercised it. For Michigan organizations that most often means ISO 27001, and we scope to the evidence your assessor expects.
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 South Lyon 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 South Lyon companies selling into larger enterprises, a current test plus a completed questionnaire is usually what unblocks the deal.
How quickly can you begin in South Lyon?
Most South Lyon engagements begin one to two weeks out, or faster against a hard deadline. A scoping call gets you a fixed price and a start date the same hour in most cases.
