# Firewall Administrator - Enterprise Next-Generation Firewall Operations for NATO with security clearance

- **Company:** WLG
- **Location:** Bergen, Belgium
- **Contract:** Permanent contract
- **Skills:** Cyber Security, Databases, Name Server, Data Logging, Scripting, Computer Network Technologies, System Availability, Firewalls (Computer Science)
- **Published:** August 25, 2026
- **Apply:** https://www.adzuna.be/details/5854640335

## About the Role

* Solid experience as a firewall administrator on next-generation platforms.
 * Good networking knowledge and familiarity with cyber security tooling.
 * Scripting for automation of routine administration.
 * The temperament for pro-active maintenance - the work is measured in what did not break.
 * Professional English, spoken and written.

## Description

This is the firewall estate itself, run centrally: installation, central management, policy, patching and the daily discipline of a queue with real response times against it. You would join a small security team in Mons as its firewall specialist.

It is a good job for someone who likes the platform side of security - where the answer to a repetitive task is a script, and where a rule change is documented before it is made.

What you would be doing

 * Build, install and configure next-generation firewalls, and bring them under central management with the right template and device group settings.
 * Configure high availability, time and name resolution settings, and keep software and threat signatures current through the maintenance windows.
 * Implement, verify and adapt firewall rulesets and policies as requirements change.
 * Work the ticket queue to the agreed response times - four hours for normal events, one hour for high and critical - across phone, mail and chat.
 * Keep logging and log forwarding correct so events reach the central database.
 * Write and maintain standard operating procedures and security documentation, and automate the recurring administration.
 * Troubleshoot with the network and platform teams, and support users on secure cross-domain exchange.
