What is the Difference Between ISO 9001 and ISO 27001?

🆚 Go to Comparative Table 🆚

ISO 9001 and ISO 27001 are two different standards that address different aspects of an organization's management system. Here are the key differences between the two:

  1. Purpose: ISO 9001 is a quality management standard, focusing on ensuring that an organization has a system in place to provide products or services that meet customer and regulatory requirements. ISO 27001, on the other hand, is an information security management standard, designed to help businesses deploy appropriate security controls to protect their information.
  2. Operational Planning and Control: While both standards require organizations to define and control processes, ISO 9001 focuses on operational planning and control for quality management, whereas ISO 27001 focuses on establishing information security controls.
  3. Certification Requirements: ISO 27001 requires organizations to implement policies and controls and provide evidence for audits, while ISO 9001 only requires organizations to define the controls.
  4. Resource Assignment: ISO 9001 does not allow resources responsible for knowledge, infrastructure, and product conformities to be tasked with other compliance duties, while ISO 27001 allows the same resource to be assigned multiple responsibilities.

Despite these differences, both ISO 9001 and ISO 27001 share some similarities, such as requiring organizations to map their internal and external aspects for compliance and involving parties relevant to the respective management systems.

Achieving both certifications can provide a competitive advantage, as it demonstrates an organization's commitment to providing better customer satisfaction and complying with various regulations.
