SII Group Belgium Tech Stack

IT services and engineering consultancy with security and infrastructure focus

IT Services and IT Consulting Brussels, Vlaams-Brabant 51–200 employees Founded 1995 Privately Held

SII Group Belgium operates a traditional IT services business anchored in enterprise software (SharePoint, Office365), application development, and infrastructure—but the project list and hiring velocity reveal an active pivot toward security. Half of active engineering work centers on PKI, IAM/PAM, and SIEM deployment; the stack includes Kafka, Kubernetes, and MATLAB alongside legacy enterprise tools. Mid-to-senior engineering hiring (19 of 22 open roles) across security and infrastructure signals scaling depth rather than breadth.
