In 2026, the NIS2 Directive represents a concrete benchmark for European manufacturing SMEs in managing cybersecurity.
The regulatory framework is now clearly defined, and the operational implications are evident: companies are required to structure their digital security approach in a solid and organized way.
In recent years, many industrial SMEs have made a significant leap forward: connected machinery, integrated ERPs, remote maintenance, suppliers and customers linked to corporate systems.
Digitalization has spread extensively, bringing efficiency, speed, and competitiveness — but it has also expanded the attack surface. And this is precisely where change must begin: with the awareness that digital security and operational continuity are now two sides of the same strategy.
Let’s address the questions we hear most frequently:
- Does my manufacturing SME fall within the scope of NIS2?
- What does adopting “state-of-the-art” security measures actually mean under NIS2?
- What documents and evidence of NIS2 compliance must we be able to demonstrate?
Companies Subject to NIS2
NIS2 significantly expands the number of organizations involved compared to the previous regulation. For manufacturing SMEs, however, it is not only about revenue figures or headcount — although exceeding 50 employees or €10 million in turnover is already a first indicator.
The central issue is your role within the supply chain. If your products or components serve strategic sectors such as energy, transport, digital infrastructure, or medical devices, it is highly likely that your organization is part of an ecosystem considered critical.
And even when the direct obligation is not immediate, pressure still comes from the supply chain. Increasingly, large industrial groups are requiring concrete cybersecurity guarantees from suppliers: audits, questionnaires, and specific contractual clauses. In this context, NIS2 compliance is not just a regulatory requirement — it becomes a competitive requirement.
What “State of the Art” Really Means
One of the most cited expressions in NIS2 is “state of the art.” There is nothing futuristic or experimental about it. It simply means demonstrating that you have adopted measures that are adequate and proportionate to your real risks.
In 2026, for a manufacturing SME, this translates into very concrete actions: protecting critical access with multi-factor authentication, managing vulnerabilities in a structured way, maintaining effective and tested backups, and controlling supplier access to corporate systems.
In a production environment where modern machinery coexists with legacy systems, the issue becomes even more sensitive. This is not only about cybersecurity in a narrow sense, but about operational continuity. A ransomware attack does not only block servers and files — it can halt production lines, delay deliveries, and compromise commercial relationships, with significant consequences for trust and reputation.
For this reason, resilience becomes a 360-degree business issue.
How to Demonstrate Compliance During an Audit or Review
A decisive element in the application of NIS2 is demonstrability.
Adopting security measures is only part of the journey. It is equally essential to produce precise and up-to-date evidence proving that those measures have been effectively implemented, monitored, and integrated into business processes. The quality of documentation and the ability to provide it quickly are concrete indicators of organizational maturity.
This translates into formally approved policies, updated risk assessments, backup logs, patching reports, incident tracking, and documented training activities. Every element must be consistent, traceable, and easily retrievable.
In the event of an audit, a client request, or a competent authority review, the speed and clarity of your response become integral to your company’s solidity and reflect your real governance capabilities.
The Role of Management
NIS2 introduces a major cultural shift: cybersecurity is a responsibility of top management.
This is a significant mindset change that should not be underestimated. Historically, cybersecurity has been perceived as a purely technical matter and therefore delegated to the IT department.
Today, it can no longer be treated that way, because it is considered a structural component of corporate risk management. That is why executive leadership must be involved, supervise the measures adopted, approve security policies, and ensure adequate resources.
In the manufacturing context, an unstructured or superficial approach can translate into unexpected production stoppages, delivery delays, and operational costs that are difficult to absorb.
From Obligation to Opportunity
When approached correctly, NIS2 can become an opportunity to strengthen the organization’s digital maturity. Greater risk control, lower probability of production downtime, stronger positioning in B2B negotiations, and increased trust across the supply chain.
In manufacturing, in 2026, the NIS2 challenge is played out through operational choices that keep production running: remote assistance, OT networks, spare parts, and suppliers.
Practical Examples
A typical first example is remote maintenance: “always-on” VPN access for the line manufacturer or system integrator becomes a highway for attackers if there are no named accounts, MFA, and a controlled jump server. From there, the real risk is lateral movement from IT systems (email/ERP) to OT environments, up to supervisory systems and HMIs.
The second example concerns vulnerability management on components that are often “difficult to patch” (MES servers, historians, line PCs). In manufacturing, exploited vulnerabilities are the leading technical cause of ransomware attacks (32%), followed by malicious emails (23%). When an attack occurs, the difference between a short and a prolonged downtime lies in recovery capability.
A third, highly relevant example in supply chains: core customers are increasingly requesting evidence regarding supply chain security and incident response (who accesses the network, with which privileges, how access is revoked, how incidents are tracked). The Directive imposes risk management measures and strict notification obligations (early warning within 24 hours, notification within 72 hours, and final report).
The First Step Toward Structured Compliance
Effectively addressing NIS2 first requires a clear understanding of your current exposure level and maturity. Without an objective snapshot of the situation, any intervention risks being fragmented or disproportionate.
For manufacturing SMEs, the most solid path begins with a structured assessment: identifying priorities, evaluating real gaps, and defining actions consistent with the operational context.
A conscious evaluation today helps avoid emergency interventions tomorrow and allows security to be progressively and sustainably integrated into business processes.
