ROC Mondriaan

ROC Mondriaan is an educational institution based in The Hague, Netherlands, providing vocational education and training. The organization serves a significant community of students and employees, operating within the Dutch regional education sector. Its core mission involves delivering structured learning programs and associated educational services to its enrolled student body. The institution's operational footprint is centered on its primary location in The Hague, where it manages academic and administrative functions. The scale of its activities is indicated by the broad impact of a major cyber incident that disrupted access for its entire operational community, affecting both personnel and learners. This event underscores the institution's role as a substantial provider of vocational education within its local market.

In August 2021, ROC Mondriaan experienced a severe cyber attack that caused widespread system outages, completely preventing employees and students from accessing files and data. The attack resulted in significant operational disruption, with no interim access to affected systems during the recovery period. In response, the institution initiated a formal forensic investigation to determine the breach's scope and secure evidence, while engaging experts to restore systems responsibly. ROC Mondriaan reported the incident to the Dutch data protection authority, acknowledging the potential for unauthorized access to personal or sensitive information. Officials did not confirm whether ransomware was specifically involved. The institution's handling of the incident demonstrates a structured approach to cybersecurity breaches, including regulatory compliance and a focus on methodical system restoration over rapid but potentially insecure recovery.
