Norway’s manufacturing and engineering sector operates where physical systems, software, and global supply chains intersect. Security leaders in this space are responsible not just for data protection, but for uptime, safety, intellectual property, and long-lived industrial systems that cannot be replaced overnight. The CISOs below stand out for their ability to operate inside that reality—where security must be engineered into operations, not layered on afterward.
Øyvind Sævareid Ellefsen — Chief Information Security Officer, Kongsberg Discovery
Øyvind Sævareid Ellefsen’s experience reflects a deep operator mindset shaped by decades of infrastructure, executive, and security leadership. As Chief Information Security Officer at Kongsberg Discovery, he builds on prior responsibility as Head of IT Security within the wider KONGSBERG group, combined with extensive hands-on experience as a chief technology officer, chief executive officer, and company owner. His background in datacenter operations, server and network design, and long-term system stewardship aligns closely with the realities of engineering-driven organizations, where resilience depends on how systems are built, maintained, and recovered—not just how policies are written.
John Arild A. Johansen — Chief Information Security Officer and Head of Security, reMarkable
John Arild A. Johansen brings experience from some of Norway’s highest-trust environments across payments, consulting, and product-led technology companies. Prior to leading security at reMarkable, he served as Chief Information Security Officer at Vipps and Sopra Steria Scandinavia, alongside earlier roles spanning security, privacy, and quality leadership. His experience reflects a balance that manufacturing and engineering-adjacent product companies increasingly need: strong governance and partner assurance without slowing innovation, product delivery, or customer growth.
Torgeir Sjursen — ICT Manager and Chief Information Security Officer, Jets Vacuum AS
Torgeir Sjursen’s experience represents the long-term operational security leadership that industrial organizations depend on. With decades of responsibility as ICT Manager and Chief Information Security Officer at Jets Vacuum AS, he operates close to the systems that keep production and delivery running. In engineering environments where technology lifecycles are measured in decades rather than quarters, this kind of continuity is critical—ensuring security decisions align with operational reality, legacy constraints, and business continuity requirements.
Marianne Mari Due — IT Operations and Security Chief Information Security Officer, HTS Hans Torgersen & Sønn AS
Marianne Mari Due’s experience is grounded in execution. Her role spans IT operations, information security, project leadership, and workforce enablement, reflecting the reality of security leadership in mid-sized industrial organizations. Rather than operating at arm’s length, her work focuses on making security practical—through daily operations, employee training, vendor coordination, and system reliability. This hands-on approach is especially valuable in manufacturing contexts, where secure behavior and operational discipline matter as much as formal controls.
Gjert Tronstad — Director of Cyber Security, Elkem ASA
Gjert Tronstad’s experience highlights the importance of identity, access, and foundational security capabilities in industrial enterprises. As Director of Cyber Security at Elkem, his background spans identity and access management, directory services, and long-term consulting in complex enterprise environments. Manufacturing organizations often rely on a mix of legacy systems, modern cloud platforms, and third-party access, making strong identity governance one of the most critical security controls. His career reflects a practical understanding of how security maturity is built through repeatable operations, reliable identity foundations, and controlled change.
Tom Remberg — Chief Information Security Officer, Bane NOR
Tom Remberg’s experience centers on aligning security with business strategy in large, infrastructure-heavy organizations. As Chief Information Security Officer at Bane NOR, his responsibilities include setting enterprise-wide security requirements, driving the strategic security roadmap, managing the security function, and advising leadership through a risk-based lens. His background in global security leadership, telecom governance, and strategic information security management positions him as a bridge between engineering realities and executive decision-making—an increasingly important role as infrastructure and manufacturing security becomes a board-level concern.
Espen Haagenrud — Senior Vice President and Chief Information Security Officer, TOMRA Systems ASA
Espen Haagenrud’s experience combines governance rigor with a strong focus on organizational behavior and accountability. As Chief Information Security Officer at TOMRA Systems ASA, he emphasizes resilience through understanding—recognizing that technology, process, and people are inseparable in security outcomes. His background in security governance, internal controls, and enterprise risk management supports global manufacturing operations where consistency, assurance, and cultural adoption are essential. This approach is particularly effective in organizations operating across regions, partners, and long-lived production environments.
Security leadership in manufacturing and engineering is becoming structural
Across these leaders, a common theme emerges: credibility comes from understanding how technology, operations, and business constraints interact over time. In Norway’s manufacturing and engineering industries, cybersecurity leadership is no longer just about protecting systems—it is about safeguarding production continuity, intellectual property, supply chain trust, and long-term operational resilience. The CISOs highlighted here stand out because their experience aligns directly with those demands, making security a durable part of how these organizations are built and run.
