Gatzke Consulting Group

Gatzke Consulting Group advises building operators, technical building services planners, facility management and IT managers on building OT, technical building networks and information security. As building automation becomes increasingly networked with IT systems, new interfaces and security requirements emerge. The consultancy conducts a structured 'Building OT Check', assessing existing building automation, networks and IoT components, evaluating their security posture against standards such as BSI IT-Grundschutz and ISO/IEC 27001, and prioritizing practical, actionable measures. Their approach is described as independent, practice-oriented and understandable, bridging the gap between building technology and IT perspectives that are often planned and managed separately.
