BESIX is a leading Belgian construction group with operations in over 25 countries across five continents. Known for iconic projects like the Burj Khalifa, the company combines innovation and scale in everything it builds.

As BESIX accelerated its digital transformation, it recognized the growing importance of a modern and proactive cybersecurity strategy—especially in the face of increasing cloud adoption, hybrid work models, and regulatory pressure.

To support this journey, BESIX partnered with Resilient Security to strengthen its Microsoft security environment and lay the foundation for long-term cyber resilience.

A strategic shift in security

The collaboration began with a restructuring of BESIX’s identity and access environment. Together, we introduced a tiered access model, segmenting critical assets such as Active Directory and VMware to reduce risk and improve control.

From there, we deployed Microsoft’s cloud-native security capabilities to gain real-time visibility, enable proactive threat detection, and automate responses, making it possible to contain incidents quickly and efficiently.

Automation and smart triggers were key to reducing IT workload while increasing security effectiveness.

Resilient PROTECT in action

Through our managed security service Resilient PROTECT, BESIX benefits from an end-to-end cybersecurity framework that includes:

• 24/7 monitoring and detection

• Proactive risk management

• Support for NIS2 compliance and governance

• Continuous improvement and strategic advisory

Our close collaboration with BESIX’s internal IT team ensures that security becomes not just a protective layer, but a driver of operational resilience and efficiency.

Looking ahead

Today, BESIX is expanding this model to its broader group, applying the same level of security maturity to other business entities. The next step in our collaboration will focus on governance, ensuring BESIX stays ahead of future compliance requirements and continues to operate securely at scale.
