A Guide to ISO 27001 Certification 

Securing ISO 27001 certification involves the formal acknowledgment by an independent and accredited certification body (CB) that an organisation's Information Security Management System (ISMS) adheres to the requirements of the Standard.  This Standard is globally recognised as a framework for establishing and sustaining effective information security practices. It offers guidelines and requirements organisations can follow to create and implement an ISMS, a systematic strategy for managing sensitive information and safeguarding it against unauthorised access, disclosure, alteration, and destruction. 

A Guide to ISO 27001 Certification 

To certify to ISO 27001, the organisation’s ISMS must be assessed by a certification body. This assessment evaluates the policies, processes, procedures, controls, and risk management practices which make up the ISMS. The certification body ensures that the organisation's ISMS aligns with the ISO 27001 standard and effectively mitigates information security risks. 

Following a successful assessment, the organisation is issued an ISO 27001 certificate. This certification serves as a guarantee to stakeholders, clients, and partners that the organisation has implemented a resilient information security management system and actively manages security risks. 

ISO 27001 certification not only boosts an organization's reputation but also fosters customer trust by demonstrating adherence to globally recognised information security standards. It establishes a framework for continual improvement, enabling the organisation to sustain and refine its information security practices over time to counter emerging threats and adapt to evolving business needs. 

When do you need to recertify to ISO 27001? 

ISO 27001 certification, issued by accredited Certification Bodies (CBs) like UKAS in the UK, typically remains valid for three years. However, throughout the three-year certification period, the selected CB conducts annual continuous assessment visits (CAVs) to confirm the ISMS's maintenance and effective operation. 

These CAVs are crucial to ensuring that the organization consistently meets ISO 27001 standard requirements and adequately addresses information security risks. If it is determined that the ISMS is not operating effectively or if there are significant non-conformities with the ISO 27001 standard, the certification body may instruct the organisation to implement corrective actions. Failure to address these issues within the specified timeframe could lead to the withdrawal or suspension of the certification. 

How do you achieve ISO 27001 certification?  

Upon completing its information security risk assessment, addressing remediation activities, and fully implementing the ISMS an organisation can pursue ISO 27001 certification by engaging a Certification Body (CB). The organisation must demonstrate the maturity and full operational status of its ISMS, having undergone a management review and internal audits within the continuous improvement cycle. 

A management review, led by top management, formally evaluates the ISMS's performance and effectiveness. This evaluation ensures alignment with business objectives, sufficient resourcing, and the capability to address information security risks. Internal audits, conducted by internal auditors or an independent team, assess the implementation and effectiveness of ISMS controls and processes, identifying any non-conformities or areas for improvement. Results from the management review and internal audits are used to evidence the ISMS’ effective function and adherance to ISO 27001 requirements. 

The ISO 27001 certification process has two main stages. In the first stage, the assessor conducts a documentation review, evaluating whether the organisation's processes, policies, and documentation align with ISO 27001 requirements. This assesses the organisation's readiness for the subsequent certification audit, scheduled 6-8 weeks later. The certification audit involves a comprehensive on-site assessment in which the assessor scrutinizes the ISMS implementation, including policies, processes, controls, and practices, seeking evidence of adherence to documented procedures. If all is in order, the assessor recommends the organisation for ISO 27001 certification. 

This recommendation stems from the assessor's determination that the organization has met ISO 27001 requirements and demonstrated compliance during the on-site assessment. The Certification Body then issues the certification, officially recognizing the organization's ISMS conformity to the ISO 27001 standard. It's worth noting that the process and timeline may vary depending on the specific Certification Body and their procedures. 

How much does it cost to certify to ISO 27001? 

The cost of ISO 27001 certification depends on the organisation's size, complexity, scope of certification, existing level of conformity, and available internal resources. Organisations can opt to pursue certification using their internal resources.  To do this, the individuals responsible for implementing and managing the ISMS must undergo training and possess a comprehensive understanding of ISO 27001 requirements. These individuals will need to conduct risk assessments, implement controls, develop policies and procedures, and prepare for the certification audit in line with ISO 27001 requirements. 

Alternatively, organisations may choose external expertise for their ISO 27001 certification project. Consultancy firms bring experience in guiding organisations through the certification process, and consultants can contribute specialised knowledge, assist in ISMS development and implementation, conduct internal audits, and offer guidance on achieving compliance with ISO 27001 requirements.  It’s important to select a trustworthy consultancy firm with a long history of successful certifications, such as URM.

The decision to use internal resources or engage consultancy support hinges on the organisation's specific circumstances. Ultimately, the overarching goal is to ensure the effective execution of the ISO 27001 certification project, leading to the establishment of a robust and compliant ISMS that aligns with ISO 27001 requirements.
