Career highlights

With a background spanning enterprise technology and cybersecurity, Xavier has spent much of his career working with organisations to solve complex business and security challenges.

At Cythera, he works across managed security, security technology, consulting and advisory services, supporting clients across areas including MDR and SOC, cloud and data security, identity, GRC, penetration testing, vulnerability management and emerging areas such as AI security.

Xavier is known for taking a considered, pragmatic approach to client relationships. He focuses on understanding the broader business problem rather than simply selling a product, bringing together Cythera’s technical specialists, services and technology partners to develop solutions that are commercially sensible and aligned to each organisation’s priorities.

Outside of work, Xavier is usually at the gym, out on a motorcycle, taking photos or finding another project to occupy his weekends.
