Choosing Between ISO 9001 and ISO/IEC 27001? Here’s Why You Might Need Both

June 3, 2025

Today it's more important than ever to ensure the safety and security of your business. As businesses expand, global standards offer a way to achieve sustainable growth. Among the most popular of these standards are ISO 9001 and ISO/IEC 27001. 


Both standards contain similarities that aim to improve organizational management systems; however, they both serve distinct purposes. One focuses on quality management, the other on information security. In many cases, choosing one over the other is not the best answer. Understanding how these standards complement each other and how to apply both to maintain security will yield a much greater benefit to you and your business.

ISO 9001 vs ISO/IEC 27001 at a glance. ISO 9001 focuses on quality management, and strives for quality consistency. It can be applied to all industries. 9001 increases customer satisfaction through quality consistency. ISO/IEC 27001 focuses on information security, and strives for data confidentiality, integrity and availability. It is especially relevant for tech companies. 27001 gains customer trust through data security.

ISO 9001 – Quality Management Systems 

ISO 9001 is a globally recognized standard for quality management. It aims to help businesses of any size demonstrate their commitment to quality whilst maintaining a high level of performance, coupled with the expectation of meeting customer needs. Compliance with 9001 requires businesses to define, establish, maintain, and continuously improve a Quality Management System (QMS). 

Implementing ISO 9001 means your business is committed to delivering customer-focused, quality products or services. The standard focuses on: 

  • Customer satisfaction (e.g. building and maintaining various customer support channels or sending out customer satisfaction surveys).  
  • Process optimization (e.g. automating workflows to minimize delays and waste). 
  • Leadership alignment (e.g. communicating goals across departments).  
  • Evidence-based decision making (e.g. adjusting operations based on customer data and feedback).  
  • Risk-based thinking (e.g. conducting risk analyses and implementing respective safeguards). 

Businesses that adopt ISO 9001 gain a structured framework for evaluating and improving their processes. This allows businesses to improve the quality of their products while meeting compliance requirements across various industries. 

But what does ISO 9001 look like in reality? As an example, we’ll use a hypothetical food manufacturer that supplies supermarkets across the country. This company complies with ISO 9001 to standardize its quality control processes across its production line.  

Raw ingredients received from suppliers are inspected for quality and shipping/packaging integrity. During preparations, another inspection might be conducted to ensure safe and sanitary cooking conditions such as temperature requirements and cooking time for sensitive ingredients, alongside other safety checks such as allergen control. Once products are finished and packaged, a final inspection will be conducted to ensure products are clean and labelled correctly with properly sealed packaging.  

By conducting and properly documenting these inspections, this company adheres tightly to the guidelines set out by ISO 9001, enabling them to confidently ensure quality and safety across their entire production line. Not only does this maintain customer trust, but it also generates indispensable insights for potential improvement.  

This is just one example. ISO 9001 doesn’t just apply to food—it applies anywhere, to any type of business across any sector. Any business that is focused on building strong customer relationships while implementing repeatable, quality processes will find 9001 a useful tool for building a strong operational foundation that is both scalable and reliable. 

ISO/IEC 27001 – Information Security Management

 In contrast, ISO/IEC 27001 is the world’s most recognized standard for information security management systems (ISMS), defining what requirements an ISMS must meet. It provides risk-based guidance on identifying and mitigating information security risks, both from inside and outside of the organization. 


While ISO 9001 focuses on providing quality products and services, ISO/IEC 27001 focuses on maintaining and protecting what makes that quality possible. It looks to safeguard the data, infrastructure and internal systems of day-to-day business operations. 

The standard focuses on: 


  • Asset management (e.g. building and maintaining an inventory of all company software or accounts). 
  • Access control (e.g. Using user permissions to restrict access of data to specified personnel). 
  • Risk assessment and treatment (e.g. assessing the current ISMS and identifying vulnerabilities). 
  • Security incident response (e.g. setting up a specific response process for detecting, reporting, and responding to cybersecurity events). 
  • Compliance with legal, contractual, and regulatory obligations (e.g. ensuring that the company’s ISMS complies with any relevant regulatory requirements, such as the GDPR). 


ISO/IEC 27001 helps businesses protect their intellectual property, as well as client and partner data. It promotes a holistic approach to security; overseeing people, internal policies, and technology. Any ISMS implemented under the guidance of ISO/IEC 27001 is a reliable tool for cyber resilience, risk management and operational excellence. 


Let’s look at an example of ISO/IEC 27001 in action, just as we did for ISO 9001 in the last section. Imagine a financial services company that provides customers with loans. To properly analyze loan applications, this company would need to handle sensitive customer information such as income statements and identification documents. To comply with ISO/IEC 27001 and protect its customer data, the company has implemented an ISMS. 


How does the company’s ISMS work? First, the company uses data encryption and user permissions to ensure that only authorized personnel can view or manage a customer’s data. Second, the company enforces regular cybersecurity awareness training for all employees (e.g. training in safe data storage, password protection, and spotting scam emails). Third, the company’s cybersecurity team monitors unusual activities, logs security events, and manages event response procedures. All these processes are documented and reviewed for potential weaknesses. 

Which One is Right for You? 

The answer depends on many factors, including the sector your business primarily operates in, the expectations of your clients, and even your own business goals. However, due to business becoming increasingly more digital, many organizations find that adopting both standards provides a comprehensive model of governance that can deliver the right guidance and protection under any circumstances. 

A chart showing when you might need ISO 9001 vs ISO/IEC 27001. ISO 9001 focuses on quality control of products and processes. ISO/IEC 27001 focuses on handling sensitive data. Both certifications would give you a holistic governance model that values both operational quality and information security.

One of the biggest advantages of these two standards is how well they integrate with one another. Both share a common framework in terms of terminology and the elements of their respective management systems. 


This allows businesses to implement both standards in tandem, which can help to streamline audits and unify documentation and process control systems. It also allows leadership to monitor risk and performance across quality and security through a single, aligned governance model. 

Final Thoughts

In the modern world, customer expectations are high, and data threats are becoming more sophisticated every day. The pressure on businesses to meet the quality and security requirements to compete has never been higher. 


 ISO 9001 and ISO/IEC 27001 offer organizations a way to build trust and reduce risk in day-to-day operations. Building on the foundation these standards set, whether adopting one or both, sets the stage for sustainable growth that will provide a secure future for your business. These standards shape the way your business operates and will quickly become a strategic asset for those looking to compete in the modern world.
