Physical Security Assessment & Design for Critical Infrastructure

Our Assessment & Design Approach

Whether supporting an existing high-consequence facility or designing security architecture for new construction, GSS delivers structured, risk-informed assessment and design services.

Our approach evaluates physical, procedural, and technological controls to strengthen overall security posture. From comprehensive architecture assessments to ground-up system design, we develop integrated solutions aligned with regulatory expectations and operational realities.

Assessment

GSS conducts structured DBT-aligned vulnerability assessments across all security layers, from perimeter controls to internal target protection strategies, validating system performance, interdependencies, and response effectiveness.

Design

GSS designs security systems from the ground up based on validated threat assessments and Design Basis Threat (DBT) requirements.

We define what must be protected and then build layered physical, electronic, and procedural controls to support that objective. Our designs account for response capability, system integration, and regulatory expectations to ensure effective and sustainable protection.
