NIS2 readiness for manufacturing and industrial suppliers
You make parts, assemble equipment, install systems or maintain plants for companies in energy, chemicals, food, medical devices, machinery or transport equipment. Several of those customers are now essential or important entities under the Cyberbeveiligingswet.
Manufacturing is itself an Annex II sector, so your larger customers are regulated, and their Article 21 duty to manage supply-chain security lands on you as a questionnaire, a contract clause, or both. Operational technology makes it sharper: a compromised supplier laptop plugged into a customer plant is the scenario their auditors describe first.
The five questions this sector gets
Each with what counts as evidence. A yes without an artefact scores nothing.
- Remote access to customer sitesWho at your company can reach a customer network or machine remotely, through what tool, with what authentication, and how access is removed when a technician leaves.
- Laptops and USB media on siteEncrypted devices, up-to-date patching, antivirus, and a rule for removable media. Customers increasingly ask for a written policy and a sample device report.
- Drawings, specifications and customer dataWhere files live, who can open them, backups with a tested restore, and what happens to a customer's data when the contract ends.
- Email authenticationSPF, DKIM and DMARC, because invoice fraud against suppliers is the most common incident customers in this sector report.
- Incident contact and timingA named person, a monitored address, and how fast you will tell the customer if you are hit, because their own 24-hour early-warning clock may depend on it.
Four things to have before the next questionnaire
Cheap, mostly visible from outside, and present in nearly every questionnaire. The rest goes into a dated plan with an owner per item.
- Email authentication and MFA on email and remote-access tools
- A device baseline: encryption, patching and a list of who has what
- A one-page incident process with the customer notification step
- A supplier list of your own, because they will ask about your sub-contractors
NIS2 supplier-readiness assessment
10 working days, fixed scope, written deliverables.
External reconnaissance, authenticated configuration review, email and domain authentication, cloud and hosting posture, and a staff phishing baseline. You receive a written report, a remediation plan ordered by risk, and an evidence pack mapped to the NIS2 themes your customer is asking about.
- External attack-surface report
- Email authentication
- Server and cloud hardening
- Web security headers
- Remediation plan
