Senior🎓
Top SchoolThomas Defise is an IT security technical lead based in Luxembourg with 8–9 years of hands-on experience securing cloud and financial environments. He leads engineering operations at Banking Circle, blending project and architecture oversight with practical DevSecOps, SRE and automation work to keep TCO low while increasing controls and ROI. His background spans SOC/EDR, vulnerability management, secure configuration and cloud security—he’s implemented Azure IaC patterns and contributed Terraform-based, security-focused changes to the popular Checkov project. Comfortable interfacing with CISOs and regulators, he translates requirements from frameworks like DORA and CSSF into achievable controls and SLOs. A co-founder and frequent tinkerer, he pairs a consultant’s client-facing discipline with a practitioner’s habit of building tests, scripts and repeatable automations. Colleagues describe him as a pragmatic threat-intelligence advocate who turns policy into measurable, operational security.
