ISO 27001 vs other cybersecurity frameworks

With cyber attacks happening every 36 seconds, businesses are looking for ways to combat cyber risks and keep their data safe – and they often turn to established frameworks and standards to guide their efforts. Two of the most well-known options are ISO 27001:2022 and the National Institute of Standards and Technology Cybersecurity Framework (NIST CSF). While both are valuable tools in strengthening cybersecurity, they differ in their scope, purpose, adoption, and application. Understanding these differences is essential for organisations to determine which framework best aligns with their needs and goals. In this article, we’ll compare the two and explain how they differ.

What is ISO 27001?

ISO 27001 is a globally recognised standard for information security management. Its goal is to help organisations establish, implement, maintain, and improve an Information Security Management System (ISMS). It addresses a wide range of information security challenges, making it adaptable for organisations across various industries.

What is the NIST Cybersecurity Framework?

Originally developed in the United States for federal agencies, the NIST CSF has gained global relevance due to its practicality and adaptability. It provides a flexible framework that helps businesses manage and minimise cybersecurity risks. While particularly valuable for businesses with specific regulatory requirements, it can also serve as a practical starting point for companies planning to transition to more formalised standards like ISO 27001.

ISO 27001 vs NIST Cybersecurity Framework

Scope and purpose:

ISO 27001 is an international standard that focuses on implementing an ISMS and achieving certification to demonstrate compliance. It provides a structured approach to identifying risks, implementing controls, and continuously improving information security processes. On the other hand, NIST CSF offers a set of guidelines and a flexible framework designed to help businesses manage and reduce cybersecurity risks. Unlike ISO 27001, it’s non-certifiable, making it more of a guide than a standard for formal compliance.

Adoption:

ISO 27001 is particularly useful for businesses that want to align with global security standards or demonstrate compliance to customers, partners, or regulators.  There are key processes that need to be applied throughout the business to achieve ISO 27001 certification, and these systems are required to be checked every couple of years if you want to remain certified. This provides comprehensive protection as the processes are embedded within the company’s security framework.

On the other hand, NIST CSF isn’t a formal standard, but acts more like a guide. Because it isn’t certified, it’s up to the discretion of the company implementing it to uphold the framework and make an active effort to improve and maintain it. There’s no official auditor to ensure everything is in place and up to scratch, and it can’t be certified.

Application:

ISO 27001 is best suited for businesses seeking certification to showcase their commitment to information security and compliance. It’s often adopted by businesses that aim to improve their security posture systematically while meeting customer or regulatory demands. Because it’s a certification, it can be used in your marketing materials and gives a competitive advantage when bidding for government tenders. In contrast, the NIST CSF is typically used by organisations looking for a more flexible framework as a guide to address specific cybersecurity risks. Unlike ISO 27001, NIST CSF doesn’t need to be certified, which means no leverage for marketing or competitive advantage. Both frameworks serve different audiences but share the same goal of strengthening security practices.

Can I have both ISO 27001 and NIST CSF?

Absolutely! Combining ISO 27001 and NIST CSF can create a powerful combination for organisations looking to improve their information security practices.

NIST acts as a guide for organisations beginning their cybersecurity journey. It provides a flexible framework to identify and manage risks, but lacks the formal structure and global recognition of ISO 27001.

If a company is already implementing the NIST CSF’s framework, they might find it easier to get certified in ISO 27001, as the two are based on similar functions. Many businesses integrate both frameworks to achieve a robust and comprehensive approach to information security.

ISO 27001 is the gold standard

Selecting the right cybersecurity framework depends on your organisation’s specific needs. Sectors like healthcare and finance often favour ISO 27001 for its emphasis on security management systems and its comprehensive approach. If you’re looking for an internationally recognised and comprehensive cybersecurity framework, ISO 27001 is the gold standard, and here’s why:

• It’s a globally recognised certification that builds trust with customers and stakeholders.
• It provides a structured framework for identifying and mitigating information security risks.
• It enhances a business’s ability to prevent, detect, and respond to cyber threats.
• It demonstrates compliance with international standards, fostering credibility and confidence.
• It reduces the likelihood of data breaches and their associated financial or reputational damage.
• It encourages a culture of continuous improvement in cybersecurity practices.
• It future-proofs organisations by addressing emerging security challenges proactively.
