CREST-accredited penetration testing Services
CREST-accredited penetration testing for the manufacturing sector
Modern manufacturing runs on two worlds that were never designed to meet: the corporate IT estate, and the operational technology on the factory floor. Attackers have worked out that where those worlds connect, a single foothold can stop a production line, expose years of design work, or turn a routine supplier payment into a six-figure loss.
The pressure is specific to your sector. Ransomware crews target manufacturers because downtime is unbearably expensive and the incentive to pay is high. Competitors and nation-state actors go after intellectual property, CAD and CAM files, formulations, tooling and process know-how that took you decades to build. Legacy PLCs, HMIs and SCADA systems that cannot simply be patched sit on networks that are often flatter and more exposed than anyone realises. And your customers, from OEMs to public-sector buyers, increasingly won’t award work without evidence that you’ve tested your defences.
Our penetration testing is built around that reality. Whether you’re testing to protect your IP, to keep production running, to satisfy an OEM’s supply-chain audit, or to meet an ISO 27001, Cyber Essentials, IEC 62443 or TISAX requirement, every engagement is scoped around your environment and the threats your operation actually faces.
You work directly with a qualified tester who understands that an unplanned outage on the plant floor is not an acceptable side effect of a security test, not a call centre and not an offshore checklist.
The full range of penetration testing for manufacturers
Different systems face different threats, so we don’t take a one-size-fits-all approach. Choose a single targeted assessment or combine services for full coverage across your attack surface, from the boardroom laptop to the shop-floor controller.

Not sure which test you need?
Most people searching “pen test” aren’t sure yet, and that’s normal. Pick the closest match, or talk it through directly with a tester. We can combine multiple testing types in a single project, and we often pair web app and network testing when a manufacturer wants to cover both the customer-facing and the internal side.
WHY TRUST CODESHIELD
Trusted & Independently verified.

Penetration testing for manufacturers of every shape and size
Manufacturers come to us because a single incident can halt output, leak years of R&D, or cost you a contract you’ve spent years winning. Our testing supports:
- Engineering, fabrication and machining firms: protecting design files, tooling data and the systems that keep the shop floor moving.
- Automotive and Tier 1/Tier 2 suppliers: meeting OEM security requirements and TISAX expectations before they cost you a place on the panel.
- Aerospace and defence manufacturers: securing controlled technical data and satisfying the security bar that comes with regulated and MOD-adjacent work.
- Food, drink and FMCG producers: defending high-throughput lines where even a short unplanned stoppage carries a serious cost.
- Pharmaceutical and medical device makers: protecting formulations, batch data and validated systems, and evidencing security for regulators and buyers.
- Industrial equipment and machinery builders: independent testing of the products you sell, ready for enterprise procurement and due diligence.
- Makers of connected and IoT products: testing the firmware, apps and cloud platforms your customers depend on.
- Multi-plant and multi-site operations: assessing larger internal networks, connected sites, remote access and OT segmentation across the business.
If your firm holds valuable IP, runs operational technology, moves large supplier payments, or sells products into regulated or enterprise markets, our penetration testing for manufacturers is built for you.
Meet your compliance requirements with confidence
Many manufacturers first come to us because a customer, insurer, auditor or standard requires an independent test. We make that requirement straightforward to satisfy, and turn a tick-box exercise into genuine security improvement.
You’ll receive a clear, audit-ready report that maps findings to what your framework actually asks for, with practical remediation advice to close the gaps, not just document them.

Our Values
What’s in your penetration testing report
The report is where a penetration test earns its value. A test is only as useful as the document that comes out of it, and ours are built to be read and acted on, not filed away. Every engagement ends with a clear, structured report that works for your technical team and your senior stakeholders alike.

When does a manufacturer need a penetration test?
Penetration testing isn’t a one-off box to tick. It’s something to build into the key moments of your operation. You should consider a test when:
Not sure which of these applies to your operation? A quick scoping conversation will tell you what you need, and, just as importantly, what you don’t.
LIVE REPORTING
Stay informed throughout your penetration test with real-time access to findings through our secure client portal.
Stay informed throughout your penetration test with real-time access to findings through our secure client portal.
As vulnerabilities are identified, they’re immediately available for your team to review, giving you complete visibility into the assessment as it progresses. Any High or Critical findings are communicated straight away via your agreed contact channels, so urgent risks are never left waiting until the final report.
Our collaborative approach also allows for interactive re-testing during the engagement. As fixes are implemented, our consultants can validate them in real time, helping to reduce outstanding vulnerabilities before testing is complete.
At the end of the engagement, your portal is updated with the final quality-assured report, providing a comprehensive record of the assessment, findings, remediation guidance and supporting evidence.

Penetration testing FAQs
Web app testing focuses on browser-based applications, while mobile app testing adds device-specific concerns such as insecure local data storage, binary protections, reverse engineering, and platform configuration, alongside testing the APIs and backend the app relies on.
Cloud providers secure the underlying infrastructure, but securing how you configure and use their services is your responsibility. Our testing focuses squarely on that customer side, where the vast majority of cloud breaches actually occur.
The cost depends on scope: the size and complexity of your network, the number of live hosts and sites, and whether you need internal testing, external testing, or both. Rather than quote a misleading flat rate, we scope every engagement individually so you only pay for testing that delivers real value. Get in touch for a tailored quote.
Wherever possible we test in a staging or non-production environment to avoid any disruption. If production testing is necessary, we agree all precautions with you during scoping to keep your application stable throughout.
Not necessarily. We can test with no access (black box), partial access (grey box), or full access to source code (white box). Grey and white box testing often uncover more, and we’ll help you choose the right approach during scoping.
Yes. Our support doesn’t end at the report. Once you’ve addressed the findings, we can retest to confirm the fixes are effective, giving you and your stakeholders verified assurance that the risks have been closed.
ISO 42001 is the international standard for AI management systems, and independent security testing helps evidence the controls it expects. Our testing and reporting map findings to relevant requirements, supporting your path to certification and demonstrating responsible AI governance.
