Working Principles
Independent
No ties to vendors, system integrators or installers. Advisory solely in the client's interest – vendor-neutral and objective.
Integrated
Physical, technical and organizational security are designed as one system. No isolated measures, but Defense in Depth.
Pragmatic
No theory for theory's sake. Every recommendation is actionable, budgetable and tailored to the organization's reality.
Standards-based
Methodologically grounded in ISO 27001/27002/27005, BSI IT-Grundschutz, DIN EN, VdS and sector-specific standards – without bureaucratic overhead.
