Security Assessment & Design

Every technology purchase and staffing decision downstream of a protective strategy is only as sound as the assessment it was built on. GSS establishes requirements first, in the direction the facility actually calls for.

OPERATIONAL CONTEXT

Every protective strategy starts with a direction of travel

For an existing facility, the assessment runs outside-in: it starts at the perimeter and moves inward the way an adversary would, evaluating detection, delay, and response as they are actually encountered rather than as they appear on a drawing.

For a facility still in design, the direction reverses. There is no perimeter to walk yet, so the assessment runs inside-out, starting from the vital areas and target sets that must be protected and working outward to size everything else — barriers, detection, response — to that requirement rather than retrofitting it later.

Both directions produce the same thing: a documented basis for what the site actually needs, established before a single sensor, barrier, or additional post is specified.

METHODOLOGY
01Requirements DefinitionProtection objectives established against Design Basis Threat capability and consequence criteria before any design decision is made.
02Outside-In AssessmentFor existing facilities: analysis begins at the perimeter and works inward, evaluating detection, delay, and response as an adversary would encounter them.
03Inside-Out DesignFor new build: analysis begins at the vital areas and target sets and works outward, sizing protective layers to what they must protect.
04Gap AnalysisMeasured performance compared against the protective strategy's actual requirements, not against assumption.
05Design Basis DocumentationFindings translated into a defensible basis for investment, staffing, and licensing decisions.
