About
Codee Ludbey leads Core42's research and advisory practice across protective security, counter-terrorism, and security design integration. Core42 translates threat and risk analysis into design decisions that project teams can act on — from concept to construction documentation.
His work spans three disciplines that rarely converge: criminology, urban design, and security engineering. That convergence is what built environment security requires — and what generalist security consulting rarely delivers. Codee holds the Certified Protection Professional (CPP) credential.
Codee is a PhD researcher at the University of Technology Sydney, School of Built Environment, conducting original research on how communities perceive and respond to security interventions in public space. His research has produced the tolerability curve framework — primary evidence on the threshold beyond which visible security stops reassuring communities and starts unsettling them. This work directly informs how Core42 calibrates security specifications for public realm and civic projects.

Research
Original research conducted through the University of Technology Sydney and Core42's advisory practice.
Protective Placemaking
Community evaluation of 73 security interventions across 52 Sydney residents. Reveals the tipping point at which visible security reads as threat rather than protection.
The State of CPTED in NSW
Systematic analysis of 100 consultant-produced CPTED reports submitted to the NSW planning system. Examines the gap between compliance and analytical quality.
Security 2030
Forward-looking research on the threat landscape and design imperatives shaping security for major built environment projects through the next decade.
Published Insights
Long-form perspectives on protective security practice.
The Security Tipping Point: What Community Research Reveals About Visible Protection in Public Space
Primary research with 52 Sydney residents across 73 security interventions, revealing the tipping point at which visible security reads as threat rather than protection.
When the Data and the Danger Diverge: Australia's Active Armed Offender Threat
Analysis of the gap between incident rate data and upstream threat conditions for AAO planning in the Australian context.
