Cyber Essentials for Manufacturing & Supply Chain
Larger manufacturers and public sector buyers are increasingly pushing security requirements down through their supply chains, so a smaller parts or components supplier can find certification suddenly becomes a condition of keeping an existing contract, not just winning a new one. Manufacturing has also seen a real rise in ransomware attacks that don't just steal data but physically halt production lines, causing direct financial loss measured in days of downtime rather than just a data breach cleanup. Where older factory equipment and modern office IT increasingly sit on the same network, a weakness on the office side can end up affecting production systems that were never designed with cyber security in mind.
Why it matters for manufacturing & supply chain
Larger manufacturers and public sector buyers are increasingly pushing security requirements down through their supply chains, so a smaller parts or components supplier can find certification suddenly becomes a condition of keeping an existing contract, not just winning a new one.

Where older factory equipment and modern office IT increasingly sit on the same network, a weakness on the office side can end up affecting production systems that were never designed with cyber security in mind.
This covers manufacturers and their suppliers of any size in a supply chain, particularly those supplying larger enterprise manufacturers, public sector buyers or defence-related programmes.
Common threats faced
- OT/IT network convergence risk
- IP and design theft
- Ransomware halting production
- Cascading supply chain requirements
Steps to get certified
A guided, hands-on path from scoping to certificate, no jargon, no guesswork.
Scoping
We agree the boundary of your assessment: a device, a network, or your whole organisation.
Self-Assessment
Complete a guided questionnaire against the five technical controls, with our support throughout.
Review
We check your submission and flag anything that needs addressing before it goes for formal assessment.
Certification
Your certificate is issued, backed by IASME/NCSC accreditation, valid for 12 months.

Manufacturing & Supply Chain questions
Yes, this has become increasingly common as larger manufacturers and public sector buyers try to reduce risk across their entire supply chain, not just their own direct systems. If a customer has made this a condition, it's worth confirming exactly what level they expect and by when, rather than assuming standard certification will always be sufficient.
Generally no, it focuses on the IT side of your business, such as office computers, servers, email and cloud accounts, rather than operational technology like production line controllers or factory sensors. Where your office IT and factory systems are connected on the same network, though, weaknesses on the office side can still create a route through to production, so the boundary is worth mapping carefully.
It reduces the risk of that data being accessed through common routes like weak passwords, unpatched software or poorly configured accounts, which are genuine ways design files get stolen. It isn't a specific intellectual property protection scheme on its own, so firms handling particularly sensitive designs sometimes add extra controls on top of what certification requires.
It depends on how your IT is structured across sites. Where systems, networks and accounts are centrally managed, you can often certify the whole organisation under one assessment, but where individual sites run genuinely separate IT setups, you may need to think about scope more carefully. It's worth mapping your actual network setup across sites before starting.
