Coen Hagedoorn Bouwgroep

Coen Hagedoorn Bouwgroep operates as a maintenance contractor primarily serving housing corporations within the Netherlands. The company's core business involves the upkeep and renovation of residential properties, managing physical infrastructure on behalf of property owners. A significant aspect of its service delivery includes handling administrative and tenant-related data for its housing corporation clients, which inherently involves processing personal information such as contact details. This operational model positions the firm as an intermediary in the Dutch housing sector, responsible for both physical maintenance tasks and the associated data management required for tenant communication and service coordination. Its work directly supports the maintenance of housing stock for corporate landlords, placing it within the broader construction and property services industry.

In June 2023, the company experienced a significant ransomware attack that resulted in unauthorized access to its IT systems. This security incident potentially compromised the confidentiality of data it managed, specifically a customer database containing tenant names, phone numbers, and email addresses. Following the attack, Coen Hagedoorn Bouwgroep reported the breach to the Dutch data protection authority, acknowledging the risk to personal data even after initially stating the chance of an actual leak was very small. The incident's impact extended beyond the initial system intrusion, as the stolen tenant information was subsequently used by the attackers to send phishing emails, demonstrating a direct misuse of the compromised data. This event highlights the company's role as a processor of sensitive tenant information and the regulatory obligations associated with that responsibility within the Netherlands.
