Organizations should invest in classroom-based user awareness training to comply with NIS 2 directives because it ensures that all employees, especially those in critical roles, have a thorough understanding of cybersecurity risks and best practices. This type of training fosters a strong security culture, making it less likely for human error to lead to breaches or non-compliance with NIS 2 requirements. By prioritizing this investment, organizations not only comply with regulatory obligations but also enhance their overall security posture and resilience against cyber threats.
