Vestas discovered a cyber security incident during 19 November 2021 and has since then together with external partners worked around the clock to contain the situation and re-establish the integrity of its IT systems. The company’s preliminary findings indicate that the incident has impacted parts of Vestas’ internal IT infrastructure and that data has been compromised. At this stage, the work and investigation are still ongoing.However, there is no indication that the incident has impacted third party operations, including customer and supply chain operations. Vestas’ manufacturing, construction and service teams have been able to continue operations, although several operational IT systems have been shut down as a precaution. Vestas has already initiated a gradual and controlled reopening of all IT systems.
