About the Customer
Our client is a leading energy provider in Europe. It operates in a highly regulated sector with critical infrastructure and sensitive customer data. The company is a large enterprise, and we have been working with it for over 8 years.
The Challenge
Operating in the highly regulated energy sector, the client faced increasing cybersecurity and resilience demands to protect their critical infrastructure and sensitive customer data.
They sought a partner to help them achieve ISO 27001 certification, which required a structured approach to establishing an Information Security Management System (ISMS), performing risk assessments, and ensuring compliance with the latest standard, and help them prepare to meet the requirements and activities needed to achieve ISO 22301 certification, which required a structured approach to establishing a Business Continuity Management System (BCMS).
Additionally, as their business expanded, they needed to extend the certification’s scope and later migrate to the updated version of the ISO standard, all while maintaining seamless operations.
The Solution
Devoteam Cyber Trust designed a phased approach to support the client at every stage.
ISO 27001 Implementation & Certification
The ISO 27001 implementation project encompassed several key phases and deliverables. Beginning with a detailed gap analysis to identify areas requiring improvement, Devoteam then developed and implemented essential policies, processes, and controls for the Information Security Management System (ISMS).
We conducted a comprehensive risk assessment, which informed the development of a targeted risk treatment plan. Throughout the implementation, training and support were provided to internal teams, helping to foster and maintain a security-first culture across the organisation. Devoteam then supported the client throughout the audit process to achieve certification within 12 months.
Post-Certification Support
We implemented Devoteam’s IntegrityGRC tool to enable effective compliance management and ensure certification maintenance year after year. Additionally, we delivered ongoing advisory services to support operational improvements and compliance reviews.
Scope Extension and Migration
Devoteam managed scope extension projects that incorporated additional business areas and geographies as their organisational needs evolved. Additionally, we provided support for the migration to the latest version of ISO 27001, ensuring comprehensive alignment with all updated requirements and standards.
Business Continuity
Devoteam led the revision of business impact analyses (BIAs) for key business processes, conducting multiple risk assessment iterations focused on critical operations while updating business continuity plans and crisis management protocols. We also ensured that all policies, processes, activities and test exercises within the business continuity system maintained strict compliance with ISO22301 standards and requirements.
The Result
Through this long-standing partnership, Devoteam Cyber Trust has enabled the client to:
- Achieve and maintain ISO 27001 certification for over 8 years.
- Enhance operational efficiency with the IntegrityGRC platform.
- Strengthen risk management practices.
- Build a scalable ISMS, supporting expansion and evolving business needs.
- Prepare and implement BCMS to achieve ISO22301 certification.
