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.

  • Web Application Penetration Testing: We test the applications your customers and staff depend on, ordering and e-commerce portals, customer and supplier extranets, ERP and MES front ends and internal tools, for issues such as injection flaws, broken authentication and insecure business logic. Essential for any manufacturer taking orders, sharing designs or exposing production data through the browser.

  • Network Penetration Testing: We assess your internal and external infrastructure, servers, firewalls, remote access and site-to-site links, and we look hard at the boundary between your corporate IT and your operational technology. Weak or missing segmentation is how an attacker gets from a phished office account onto the network that runs your machines. Best suited to firms with in-house IT estates, connected sites or converged IT/OT networks.

  • Cloud Penetration Testing: We evaluate the cloud environments most manufacturers now rely on, Microsoft 365, Azure, AWS and Google Cloud, for the misconfigurations, excessive permissions and exposed services that lead to breaches of email, ERP data and document stores. Increasingly important as more of your ERP, quality and design systems move off-premise.

  • LLM / AI Penetration Testing: We test the AI and large language model tools manufacturers are adopting for design assistance, quality inspection, demand forecasting and maintenance, targeting the threats traditional testing misses: prompt injection, data leakage, model manipulation and insecure integrations. Increasingly relevant as you deploy AI features and work towards standards such as ISO 42001.

  • Social Engineering Testing: Your technology is only as strong as the people using it, and manufacturers are a prime target for phishing and invoice-redirection fraud, particularly around large supplier and capital payments. We test how your team stands up to phishing, pretexting and other human-focused attacks, then help you close the gaps with practical guidance.

  • Mobile Application Penetration Testing: We test iOS and Android applications for insecure data storage, weak encryption and API vulnerabilities, essential for any manufacturer offering customers or field engineers a mobile app.

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.

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.

  • Customer and OEM supply-chain audits: evidencing your security posture when a larger customer’s procurement or due-diligence process demands it, often the difference between winning and losing the work.

  • Cyber Essentials & Cyber Essentials Plus: hands-on assessment beyond the self-certified baseline, increasingly expected for supply-chain membership, public-sector and defence-adjacent contracts.

  • ISO 27001: independent testing to evidence your information security controls.

  • IEC 62443: testing aligned to the industrial automation and control systems standard, for firms securing OT environments to a recognised baseline.

  • TISAX: supporting the assessment automotive customers expect from their supply chain.

  • NIS Regulations: where your operation falls in scope as an operator of essential services, or where you supply customers who do.

  • UK GDPR & the Data Protection Act 2018: demonstrating appropriate technical measures for the employee, customer and commercial data you hold.

  • Professional indemnity & cyber insurance: satisfying the security questions insurers now ask before they renew or quote.

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.

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.

  • Executive summary: A plain-English overview of what we tested, what we found, and what it means for your business, written so a non-technical reader can understand your risk position in a couple of minutes.

  • Risk-prioritised findings: Every vulnerability and misconfiguration we identify, rated by severity and real-world impact, so you know exactly what to fix first. No noise, no padding, just the issues that matter, in the order they matter.

  • Technical detail and proof of concept: For each finding, a clear explanation of the issue, proof-of-concept evidence showing how it could be exploited, and everything your team needs to reproduce and verify it.

  • Benchmarking against best practice: Where relevant, findings are mapped against CIS benchmarks and cloud provider best practice, so you can see exactly where your configuration drifts from a secure baseline.

  • Practical remediation advice: Actionable, specific guidance on how to fix each finding, not generic best-practice statements, but steps tailored to your environment. This is the part clients tell us they value most.

  • Debrief and support: The report isn’t the end of the conversation. We walk your team through the findings in a debrief session, answer their questions, and stay on hand as you work through remediation.

Green technical background

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:

  • You’re launching a new customer portal, connected product or ordering system: test before it’s exposed to real customers and real attackers, not after.

  • You’re preparing for an ISO 27001, Cyber Essentials, IEC 62443 or TISAX assessment: these frameworks expect independent testing as part of certification.

  • A customer, OEM or insurer is asking for it: supply-chain audits and insurance renewals increasingly require evidence of penetration testing before anyone will proceed.

  • You’ve changed your infrastructure or shop floor: cloud migrations, new production lines, ERP or MES rollouts and IT/OT convergence projects can all introduce vulnerabilities that weren’t there before.

  • You’re merging with, acquiring or being acquired by another firm: understand the security posture of what you’re taking on, or reassure the people investing in you.

  • You’ve had a security incident or a near miss: verify the gap is closed and check for anything else an attacker may have reached.

  • It’s simply been a while: best practice is at least once a year. If you can’t remember your last test, you’re overdue.

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.

Penetration testing FAQs

What’s the difference between mobile app and web app penetration testing?2026-07-20T08:39:16+00:00

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.

How does the shared responsibility model affect testing?2026-07-27T07:27:38+00:00

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.

How much does network penetration testing cost?2026-07-27T08:41:24+00:00

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.

Do you test in production or a staging environment?2026-07-27T09:03:14+00:00

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.

Do you need our source code to test the app?2026-07-20T08:39:05+00:00

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.

Do you offer retesting after we fix the issues?2026-07-27T09:03:02+00:00

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.

How does AI penetration testing support ISO 42001 compliance?2026-07-27T10:41:48+00:00

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.
