Endpoint Security Expert (Trellix, DLP and Drive Encryption) for NATO with security clearance

Endpoint Security Expert (Trellix, DLP and Drive Encryption) for NATO with security clearance Own the endpoint security stack end to end — Trellix across Windows and Linux, from threat prevention and DLP to the root cause nobody else got to the bottom of. Endpoint security is where a lot of good intentions meet a lot of real machines. A multinational defence organisation in Brussels needs someone who genuinely knows the Trellix product range and can run it across a mixed Windows and Linux estate — not just install it, but keep it healthy, tuned and understood. The role mixes engineering with service delivery: high availability matters, ITIL process matters, and so does the ability to take an alert nobody can explain and follow it to its root cause. What you would be doing Implement and manage the full range of Trellix products — threat prevention, application control, host firewall, data loss prevention, drive encryption and the rest — on Windows end user devices and on Windows and Linux servers. Deliver that service in a complex IT environment, following ITIL processes and keeping availability high. Analyse security events, logs, alerts and endpoint data exchange. Drive root cause analysis and problem solving on issues that do not resolve themselves. Document what you do and share the knowledge so the team is not dependent on one person. Take ownership of technical issues and see them through. What we are looking for Recent, hands-on experience implementing and managing the Trellix product range across Windows and Linux. Service delivery experience in a complex IT environment, working to ITIL processes. Strong root cause and problem-solving skills, and strong analytical skills generally. Strong documentation and knowledge-sharing habits. The ability to work independently and take ownership. Strong communication and coordination skills. The role is based in Brussels, Belgium, on site for most daily activity with a limited possibility of one day a week remote, from early November to the end of December 2026.
