When people first hear about ISO 27001, they often misunderstand what it involves. Here’s a look at some things ISO 27001 is not, to help clear up the confusion.
It’s Not About Specific Cyber Security Controls
Yes, ISO 27001 requires organisations to implement security controls, but it doesn’t dictate which technologies or solutions you must use.
27001 is not a standard that will tell you to install a specific brand of firewall or use a particular encryption protocol. What it does do is require you to assess risks and decide on the appropriate controls to manage those risks effectively.
The focus is on managing information security, not prescribing exact technical measures.
Your approach will vary depending on the size of your organisation, the nature of your data, and the specific threats you face.
It’s Not a ‘Do It Once and Forget About It’ Activity
Implementing ISO 27001 is not a one-off task. It’s designed around the concept of continuous improvement.
After achieving certification, the real work begins—monitoring, maintaining, and refining your security processes. Regular reviews, audits, and improvements are key to keeping your system relevant and effective.
ISO 27001 requires the ongoing management of risks and constantly adapting your controls to the changing threat landscape. This is why the standard involves annual internal audits and regular management reviews to ensure that your Information Security Management System (ISMS) stays effective and aligned with your organisation’s goals.
It’s Not About Achieving Perfection from Day One
There’s no expectation of an extremely mature, sophisticated information security process when you first implement ISO 27001.
The goal is not perfection—it’s about understanding your current position and improving over time.
A minimum level of control is necessary to get started, but what matters most is that you engage in regular reflection and refinement of your processes.
The standard encourages a cycle of improvement, which means that even organisations with fairly basic controls can achieve certification as long as they demonstrate a commitment to ongoing enhancement.
It Doesn’t Automatically Make You GDPR, HIPAA, or Other Compliance-Ready
While ISO 27001 can be a strong foundation for meeting various regulatory requirements like GDPR or HIPAA, certification doesn’t automatically make you compliant. They each have their own requirements, and ISO 27001 won’t cover everything.
For example, GDPR has specific rules about data processing, consent, and the rights of individuals that ISO 27001 does not address directly.
ISO 27001 helps you manage the security aspects of compliance by improving your information security practices, but additional measures will be necessary to meet the full scope of specific regulations.
It helps you consider and articulate the influences on your security, which GDPR or HIPAA may be, but it doesn’t specifically help you address these requirements.
So, What Is ISO 27001?
Now that we’ve clarified what ISO 27001 is not, let’s talk about what it actually is.
ISO 27001 is an internationally recognised standard for managing information security. At its core, it’s about creating and maintaining an Information Security Management System (ISMS), which helps you manage and reduce risks to your organisation’s information assets.
It’s a systematic approach that covers not only technical controls but also people, processes, and policies.
The standard is built around the Plan-Do-Check-Act cycle, which encourages continuous improvement. It involves risk assessments, defining security policies, implementing necessary controls, and ensuring the system remains effective through regular audits and reviews.
Ultimately, ISO 27001 is about managing risk in a structured, proactive way. It helps organisations of all sizes improve their information security posture and adapt to new challenges.
By getting certified, you demonstrate to clients, partners, and regulators that you take information security seriously and have a well-structured system to protect it. But remember, it’s an ongoing journey, not a destination.
