OSG Hengelo

OSG Hengelo is a scholengemeenschap based in the Netherlands, with its headquarters located in the country. As a school community, it provides secondary education to a diverse student body, offering various educational tracks such as vmbo, havo, and vwo programmes. The organisation serves approximately 2500 students and staff, indicating a moderate size within the Dutch secondary education sector. Its core activity revolves around delivering curriculum instruction, supporting student development, and facilitating access to learning resources. Being a scholengemeenschap, OSG Hengelo operates as a collaborative entity that may encompass multiple school locations under a unified governance structure. This structure enables shared services and coordinated educational offerings across its constituent institutions.

In May 2023, OSG Hengelo experienced a ransomware attack that encrypted its servers and disrupted essential ICT services, including WiFi, printers, and telephone systems, affecting the ability of students and staff to work online and access digital resources. A subsequent ransomware incident occurred on June 13, 2023, during which the organisation engaged in negotiations with the attackers and ultimately reached a deal to restore services. Following both incidents, recovery efforts gradually reinstated WiFi and printer functionality for users. The attacks prompted ongoing investigations by IT experts to determine the scope of data compromise and the origins of the threats. No explicit information about ownership or parent‑subsidiary relationships is provided in the available sources. The organisation remains active in providing educational services while continuing to address cybersecurity resilience.
