Northwave Announces Leadership Transition in Daily Operations

Utrecht, 26 March 2026

Northwave Cyber Security announces an evolution in its leadership structure as CEO Steven Dondorp hands over the day-to-day management of the organisation after more than 20 years leading the company’s operations.
 
Dondorp will remain Chief Executive Officer and Chair of the Board, focusing on strategic guidance, governance of the Board, and ownership of the company. Daily operations will now be guided by a strengthened executive leadership team consisting of the President, CFO, and COO. Northwave’s President, Petra Oldengarm, and CFO, Sander Roosendaal, were already serving on Northwave’s board. Now, COO Kevin Jonkers has joined the board to further reinforce operational leadership.
 
Within this structure, responsibilities previously held by the CEO will be distributed across the executive team:
 
  • President – business strategy and day-to-day leadership of the organisation
  • COO – operational management and execution of daily business
  • CFO – oversight, governance, and risk management
This transition reflects Northwave’s continued growth and natural evolution of its leadership structure as the company expands its presence and services across Europe.

President and COO become the public leadership of Northwave

Petra Oldengarm, President, and Kevin Jonkers, COO, who joined Northwave in September and August 2025 respectively, will represent the company externally with clients, partners, and the broader cyber security community.

Steven Dondorp emphasises this transition reflects the strong leadership already present within the organisation:

“Over the past two decades, Northwave has grown into a trusted cyber security partner for organisations in Europe. That success is the result of the exceptional people we have built this company with.

I have worked closely with Petra and Kevin for many years. They bring a wealth of experience and a strong commitment to making our digital world safer. I have complete confidence in them to lead Northwave into its next phase while maintaining the professionalism and values that define our organisation. I am proud to support them and the broader leadership team as CEO and Chair of the Board.”

Going forward, President Petra Oldengarm and COO Kevin Jonkers will serve as the primary contact points for external stakeholders and media.
