Denmark’s energy and utility companies run power grids, water systems, and district heating that the country depends on every day, and with NIS2 raising the bar for critical infrastructure, their security leaders are under growing pressure. The four CISOs below protect energy groups and regional utilities, and their careers stretch from shipping offices to warships. One began as a shipping apprentice in 1984 handling bookings for lines including Maersk. Another spent nearly three decades in the US Navy, including building a command center to protect Iraq’s offshore oil terminals. A third led security for PwC across 33 countries before moving into energy, and a fourth taught algorithms at Aalborg University before becoming his hometown utility’s first CISO.
Nicholas Jancey – Group CISO & Head of IT Infrastructure (Interim), Andel
Nicholas Jancey started in IT support at PricewaterhouseCoopers and the Royal Danish Ministry of Finance, then worked as an information security consultant at NNIT and as corporate IS/IT compliance officer at Nycomed. Over seven years as information security manager at Carlsberg Group, he advised senior management, ran security operations center activities, and reviewed security in OT environments. He returned to PwC in 2018 as CISO of PwC Denmark, serving as deputy to the CIO, and later led territory CISOs across the Nordics, then 33 countries across the Nordics and Africa, as a member of PwC’s EMEA CISO leadership team. Jancey joined Andel as Group CISO in September 2025, responsible for cyber and information security across the group and its subsidiaries, and since March 2026 has also served as interim head of IT infrastructure.
Jacob Larsen – CISO, Aalborg Forsyning
Jacob Larsen taught algorithms and data structures as a teaching assistant at Aalborg University, then developed SAP payroll systems at KMD. He spent more than 14 years at Nykredit, moving from software consultant and senior developer to IT infrastructure architect, where he became the bank’s primary specialist for security assessments of cloud and outsourced solutions. Larsen became CISO of Aalborg Forsyning in February 2023, building its information security program by transforming an existing GDPR team into a GRC and IT/OT security team, developing governance for NIS2 readiness, and introducing cybersecurity reporting to executive management after educating the board and C-suite. He holds an MSc in computer science.
Ian Erdmann – CISO, SEAS-NVE
Ian Erdmann started as a shipping apprentice in 1984, handling bookings for lines including Maersk, and went on to build and lead the five-person IT department at shipping company Thor Jørgensen, representing the A.P. Møller group on the board of EDI Transport Danmark. He spent nine years as an information security consultant for Novo Nordisk and NNIT, performing more than 50 IT security risk analyses and leading NNIT’s BS 7799 certification. After managing IT risk at KPMG, he led corporate information security at Lundbeck and worked as a lead IT security specialist at DONG Energy. Erdmann has served as CISO of SEAS-NVE, the electricity grid and energy company, since April 2018. He holds CISSP, CISA, and CISM certifications.
Kristian Kearton – CISO, Kamstrup
Kristian Kearton enlisted in the US Navy as a quartermaster in 1990 and was a plank owner of the USS Ashland before becoming an officer. Over a long Navy career, he served as CISO for US Pacific Command’s networks, defending systems serving more than 3,000 users against nation-state attacks, and built a command and control center integrating radar, video, and communications to protect Iraq’s offshore oil terminals. He led the naval communication station in Rota, Spain, serving 18 sites in eight countries, and as director of global cyber operational risk assessment at Fleet Cyber Command led a team of 88 whose new inspection program helped mitigate a zero-day exploit two weeks before a nation-state deployed it. After leaving the Navy, he directed Ramboll’s global security operations center, cutting incident response time by 80%. Kearton became CISO of Kamstrup in May 2025, and also serves as chief strategy officer of KANO Cyber Institute.
Keeping the Grid Secure
These four leaders bring very different backgrounds to protecting Danish critical infrastructure. Jancey and Erdmann built long careers in corporate security across brewing, pharmaceuticals, and consulting, while Larsen moved from software development into security architecture. Kearton carried military cyber operations experience into Danish industry. Together they help keep the power, water, and heat flowing as threats to critical infrastructure grow.
