What is the difference between ISO 9001 and ISO 27001?

ISO standards are internationally recognised guidelines that help organisations improve their processes and systems.

Two of the most popular standards are ISO 9001 and ISO 27001. While both are management system standards, they focus on different aspects of your business.

Quality and information security are crucial for any modern business. ISO 9001 helps you manage quality and customer satisfaction, while ISO 27001 focuses on information security.

Understanding the core function of these standards and their differences is essential if you’re considering certification for your organisation, and that’s what this blog is all about.

ISO 9001: Quality Management System

ISO 9001 is all about quality management. Its purpose is to help you consistently meet customer requirements, enhance customer satisfaction and business performance, and provide a sound basis for sustainable development activities. It’s based on the following seven quality management principles:

  • Customer focus emphasises understanding and meeting customer requirements, striving to exceed customer expectations and maintaining strong customer relationships.
  • Leadership highlights the importance of establishing unity of purpose and direction within an organisation, creating an environment where people are fully engaged in achieving quality objectives.
  • Engagement of people recognises that competent, empowered and engaged people at all levels of an organisation are essential to enhance its capability to create and deliver value.
  • Process approach involves managing activities and resources as interrelated processes that function as a coherent system, leading to more consistent and predictable results.
  • Improvement stresses the importance of continual improvement of an organisation’s overall performance, products and services as an ongoing objective.
  • Evidence-based decision-making emphasises that decisions based on the analysis and evaluation of data and information are more likely to produce desired results.
  • Relationship management focuses on managing relationships with interested parties, such as suppliers, to optimise their impact on an organisation’s performance.

ISO 27001: Information Security Management System

ISO 27001 focuses on information security. It can help you protect your organisation’s information assets. ISO 27001 covers all types of information, whether digital (including cloud-based), paper-based or knowledge held by your employees. It’s based on three fundamental principles, known as the ‘CIA triad’:

  • Confidentiality ensures that information isn’t made available or disclosed to unauthorised individuals, entities or processes. It’s about protecting sensitive data from unauthorised access and maintaining privacy.
  • Integrity safeguards the accuracy and completeness of information and processing methods. It ensures that data can’t be modified in an unauthorised or undetected manner, maintaining its trustworthiness and consistency throughout its lifecycle.
  • Availability ensures that only authorised users have access to information and associated assets when required. It’s about making sure that data and systems are accessible and operational when needed, within agreed-upon parameters.

Additionally, ISO 27001 includes Annex A, a list of 93 security controls that you should strive to implement.

Key differences between ISO 9001 and ISO 27001

While both standards aim to improve your organisation’s management systems, they have several key differences. ISO 9001 focuses on quality management across your entire organisation, while ISO 27001 specifically targets information security.

ISO 9001 applies to all processes that affect product or service quality, while ISO 27001 is primarily concerned with information security processes and assets.

Both standards require risk assessment, but their approaches differ. ISO 9001 takes a broader view of risks and opportunities affecting quality objectives. ISO 27001 specifically focuses on information security risks, including cybersecurity and personal identifiable information (PII).

And as mentioned above, ISO 27001 includes Annex A with specific security controls, which isn’t present in ISO 9001. However, ISO 9001 has more detailed requirements around customer satisfaction and product or service delivery.

Similarities and overlaps

Despite their differences, ISO 9001 and ISO 27001 also share several similarities. Both standards follow the High-Level Structure – sometimes known as Annex SL – used by all modern ISO management system standards. It makes integration easier if you’re implementing multiple standards.

Both standards require involvement from your senior leadership and top management teams. Both require you to control documents and records.

Both standards require regular internal audits and management reviews to ensure the effectiveness of the management system. And both emphasise the need for ongoing improvement of the management system. These common elements mean that if you’ve implemented one standard, you’ve already laid some of the foundations required for the other.

Benefits of implementing both standards

Implementing both ISO 9001 and ISO 27001 can bring significant benefits to your organisation.

You can create a more robust and comprehensive management system by addressing both quality and information security. Demonstrating commitment to both can significantly boost customer trust.

Dual certification can set you apart from competitors who may only have one or neither certification. And an integrated approach can lead to more efficient processes and better overall business performance.

While it can initially be more expensive to implement multiple standards, doing them at the same time will save you money in the long run.

Strategies for implementing ISO 9001 and ISO 27001 together

ISO 9001 and ISO 27001 share common elements that make simultaneous implementation beneficial. The key to successfully implementing both standards lies in recognising their similarities. If your organisation is looking to implement more than one standard, we’d recommend you do them at the same time. It saves time and reduces duplication of work. For our clients, it would also save money, because we offer a discount on implementing more than one standard at a time.

Start with the elements common to both standards, such as document control and management review. Remember, the goal is to create a system that works for your organisation, not just to tick boxes for certification.
