Your job

Security monitoring is only as strong as the insight it provides. As a Senior Cyber Security Specialist at VodafoneZiggo, you make sure our monitoring and logging capability delivers the quality and visibility our Cyber Security Incident Response Team needs. Within Technology and the CISO domain, you connect the Cyber Security Incident Response Team, internal technical teams and external security providers. Together, you set the direction, improve detection quality and close gaps in our monitoring. Cyber risks, new threats, business priorities and regulatory requirements become clear requirements and improvements. You also dive into logs, test solutions and run proof of concepts when needed. This is a strategic and governance-focused role with enough technical depth to challenge what we deliver and why.
