Implementing ISO27001:2022 can be a complex process — but it does not have to be if approached correctly. Below, we outline the key steps involved in successfully implementing ISO27001.
Implementing ISO27001 is a process that ranges from understanding the standard’s requirements to achieving certification. It is a strategic decision that can significantly enhance an organization’s information security, strengthen customer trust, and support compliance with legal and regulatory requirements.
Our guide will dive into this process, present the key steps, and help your organization navigate the implementation in a structured and secure way — leading to international recognition of your information security efforts.
ISO27001 is a globally recognized standard for managing information security. It enables organizations to safeguard sensitive data, manage risks effectively, and ensure compliance with regulatory obligations.
ISO — the International Organization for Standardization — is an independent, non-governmental body comprising 161 national standardization agencies.It drives the creation of globally relevant standards by enabling expert collaboration, supporting innovation, and addressing critical global issues
The number ‘27001’ refers to a set of specific standards and requirements for how an Information Security Management System (ISMS) should be implemented and maintained within an organization. ISO27001 is based on a risk-driven approach to managing information security, and the standards are designed to systematize security procedures and practices.
Most companies have fire and burglary alarms installed to prevent major operational threats — but data and information security should be treated with equal importance. When information security is lacking, not only are business clients put at risk, but a range of new regulations and directives now require data protection to avoid fines and legal consequences.
With an ISO27001 certification, your company gains a first-class management system that ensures top-level quality, security, and efficiency.
At the same time, an ISO27001 certificate helps promote international trade, with up to 85% of business clients viewing the certification as a mark of trust.
ISO27001 applies to a wide range of organizations, regardless of industry, that manage data and seek to safeguard against cybersecurity risks.
The certification not only helps meet regulatory requirements such as NIS2 and DORA, but also provides a structured approach to information security and risk management.
For many businesses, ISO27001 certification has become a client requirement — serving as a recognized benchmark for robust information security.
By implementing ISO27001, your company can demonstrate a strong commitment to information security, enhance customer trust, and reduce the risk of data breaches.
This can also lead to improved business opportunities and a competitive advantage in the market.
While the implementation of ISO27001 can appear complex, it is a crucial step toward safeguarding your company’s information assets and aligning with recognized cybersecurity standards. Our six-step framework supports the structured development and ongoing management of a robust Information Security Management System (ISMS).
The first step in implementing ISO27001 is to define the scope of the ISMS.
This step includes identifying all information assets requiring protection — including databases, servers, and applications — as well as the physical or digital locations where these assets are stored and processed. In addition, it is essential to define who has access to the information.
The next step is to conduct a risk assessment to identify potential risks to the types of information covered within the ISMS scope.
The process includes assessing both the probability and potential impact of threats such as cyberattacks, data breaches, and human errors. Following this analysis, suitable controls can be selected and applied to reduce the identified risks.
Based on the results of the risk assessment, a Risk Treatment Plan should be developed outlining the controls you will implement to mitigate the identified risks.
The plan should specify the actions to be taken, the responsible individuals, and the timeline for implementation.
The following phase involves executing the controls specified in the Risk Treatment Plan. These measures may range from deploying security tools and setting up access management systems to establishing formal security policies and operational procedures.
It is important to ensure that all employees are aware of the controls and understand their role in maintaining security.
After implementing the controls, the ISMS should be continuously monitored and periodically reviewed to verify its effectiveness and ensure ongoing compliance.
This may include internal audits, reviewing security logs, and analyzing incident reports. Any issues or weaknesses identified should be addressed through corrective actions.
As a final step, you may choose to pursue certification of your ISMS through an accredited certification body. This process includes an independent audit to confirm that your system complies with the ISO 27001 standard.
While certification is not mandatory, organizations can fully adhere to the standard without it. That said, certification serves as a strong signal of compliance and builds trust among clients, partners, and regulators.
If your company processes personal data, it is worth considering an extension of ISO27001 with ISO27701. This extension integrates a Privacy Information Management System (PIMS) into the existing ISMS (ISO27001 implementation).
ISO27701 is an extension of ISO27001 that adds a Privacy Information Management System (PIMS) for the protection of personal data and GDPR compliance.
ISO27701 is an extension of ISO27001 that adds a robust Privacy Information Management System (PIMS) for handling personal data. With ISO27701, the foundational security elements of ISO27001 are expanded to include specific data protection requirements — including those of the GDPR. This extension creates a strong and internationally recognized system for managing personal data.
An effective PIMS can support strong compliance with data protection regulations by simplifying the management of complex privacy requirements.
As a powerful extension to ISO27001, ISO27701 strengthens your organization’s capacity to safeguard personal data. Its structured framework supports more efficient and consistent alignment with GDPR requirements
ISO27701 implementation and certification clearly signal an organization’s dedication to data privacy, enhancing credibility and building trust with clients and stakeholders. The standard also improves risk governance by enabling systematic identification and mitigation of privacy-related risks.
Since ISO27701 builds directly on the foundation of ISO27001, it is a logical and easily integrated extension. For organizations that have implemented or are planning to implement ISO27001, adding ISO27701 is both seamless and highly beneficial.
This is because the implementation follows the same process as described above.
