Most EU member states have now transposed the NIS2 Directive. Its supply-chain rules reach Turkish IT, software and industrial suppliers through contracts and questionnaires.
Editorially structured from the original publication.The report in brief.
The NIS2 Directive, Directive (EU) 2022/2555, requires medium and large organisations in 18 sectors, from energy and transport to manufacturing of electronics, machinery and vehicles, to manage cybersecurity risk, including risk in their supply chain. The transposition deadline was 17 October 2024. Most member states missed it, but by spring 2026 a large majority had adopted national laws; Germany’s took effect on 6 December 2025. Article 21 makes supply-chain security one of the minimum measures. EU entities must take into account the vulnerabilities of each direct supplier and the quality of their products and security practices. In practice they do this through questionnaires, contract clauses, audit rights and incident notification duties placed on suppliers. For a Turkish software house, managed service provider or supplier of connected industrial equipment, NIS2 is rarely a direct legal duty. It is a sales condition. The supplier that can show one credible security evidence pack, and commit to realistic incident notification, keeps the contract; the one that answers each questionnaire from scratch spends time and still looks risky.

Answer once, credibly
For a Turkish software house, managed service provider or supplier of connected industrial equipment, NIS2 is rarely a direct legal duty. It is a sales condition. The supplier that can show one credible security evidence pack, and commit to realistic incident notification, keeps the contract; the one that answers each questionnaire from scratch spends time and still looks risky.
