This milestone underscores Clavister’s commitment to protecting sensitive data, ensuring the highest standards of security, and enabling trusted partnerships with customers and stakeholders across critical sectors such as public administration, telecom and defence.
 
“Achieving ISO 27001 certification is a major step forward in our strategy,” said John Vestberg, CEO of Clavister. “For many of our stakeholders, this certification is not just important – it is mandatory. By meeting this internationally recognised standard, we make it easier for future partners, prospects, and customers to assess and trust the quality of our ways of working.”
 
The certification process began in May 2024 and concluded with a comprehensive audit in May 2025 conducted by DNV, one of the world’s leading certification bodies. ISO/IEC 27001 is the globally accepted standard for establishing, implementing, maintaining, and continually improving an information security management system. Certification verifies that Clavister applies systematic risk management processes to safeguard data confidentiality, integrity, and availability.
 
“While this certification is an important achievement, it also marks the beginning of a continuous process,” added Vestberg. “We will maintain and evolve our management system with annual DNV audits to ensure we keep meeting the highest standards.”
 
Clavister’s ISO 27001 certificate is now available for stakeholders and partners upon request.
