In her advisory role, Pretorius will provide strategic guidance to CyberOne’s executive team—supporting the evolution of its Microsoft partnership and the continued growth of Assure 365, CyberOne’s modular approach to delivering Microsoft Security. Built for flexibility and depth, Assure 365 enables organisations to adopt tailored Managed Services across identity, endpoints, data, infrastructure and threat protection.
“We are delighted to welcome Tracey,” said Dominic List, CEO of CyberOne. “Her global industry experience and expertise align perfectly with our vision of being a world leader in Microsoft-based MDR and will bring further improvements to being one step ahead of threat actors. Tracey’s involvement reflects our continued commitment to advancing our cyber strategy, deepening our security culture and delivering on our mission to be best-in-class Managed Services.”
“As the co-founder of Microsoft’s Women in Security (MWiS) initiative, Tracey also brings a unique ability to guide the next generation of cyber talent—particularly women—while mentoring CyberOne’s growing and diverse team, advancing our strategic direction and deepening our culture of resilience.”
“CyberOne is a dynamic and purpose-driven organisation at the forefront of Managed Security Services,” said Pretorius. “I’m delighted to support their continued success and growth. Building a cyber-first culture is vital and CyberOne’s commitment to the principles behind Microsoft’s Secure Future Initiative provides a strong foundation for what comes next.”
The advisory board addition builds on a period of strong momentum for CyberOne. The company holds Microsoft Solution Partner Designations in Security, Infrastructure (Azure) and Modern Work, along with Cloud Security and Threat Protection Advanced Specialisations. CyberOne is also an NCSC Assured Provider and a Level 2 Accredited Cyber Incident Response organisation, holding CREST certifications across Penetration Testing, SOC and Cyber Incident Response. CyberOne’s appointment of Pretorius reflects its evolving commitment as a strategic cyber security partner—combining 24x7 Managed Services with industry-recognised Consulting and Professional Services to help customers navigate an increasingly complex threat landscape.
Looking ahead, CyberOne will showcase its services, joining Microsoft on their stand at Infosecurity Europe, taking place 3–5 June 2025 at the ExCeL Centre in London. This major industry presence further underscores the strength of the CyberOne-Microsoft partnership and its vision for building a more secure digital future.
