ISO 9001:2015

ISO 9001:2015 and Cybersecurity/IT


Origin and Development


ISO 9001:2015 is a quality management system standard developed by the International Organization for Standardization (ISO), a global federation of national standards bodies. However, it's important to clarify that ISO 9001:2015 is not specifically a cybersecurity or IT certification—it's a general quality management standard applicable to any organization regardless of industry. The standard was released in 2015 as the fifth revision of ISO 9001, which was first published in 1987. For cybersecurity specifically, ISO created ISO/IEC 27001, which is the actual information security management system standard.


Industry Value and Importance


ISO 9001:2015 is valued across industries because it demonstrates an organization's commitment to consistent quality management, customer satisfaction, and continuous improvement. When applied to IT and cybersecurity contexts, it helps organizations establish systematic processes for service delivery and quality assurance. However, for cybersecurity-specific certification, organizations typically pursue ISO/IEC 27001, which directly addresses information security controls, risk management, and data protection. Both certifications are internationally recognized and often required for government contracts, enterprise partnerships, and demonstrating due diligence to customers and stakeholders.
