Threats, regulation and security best practices for businesses in Luxembourg.
A Luxembourg SME is not targeted because it is interesting, but because it is reachable. Most incidents come down to opportunism: phishing, ransomware, payment fraud.
This section treats security as a management constraint, not a technical speciality. It follows regulation: the NIS2 directive widens the range of entities subject to security obligations, and many companies are discovering they fall inside it.
NIS2 compliance is not declared, it is evidenced through documents. Since 3 August, the ILR has published the templates for those documents: they show precisely what is expected.
It documents the threats actually seen in the country, rather than the global catalogue of possible attacks.
It sets out where to start and in what order: verified backups, stronger authentication, a written response plan. Expensive measures come afterwards, once the basics hold.
Compliance and actual security do not overlap. A company can tick every box in a framework and still be exposed to payment fraud; the reverse happens too. Articles keep the two apart.
Incidents are reported when they are documented, with what was made public and what was not. No company is named as a victim without a verifiable source.
