Core42

Security that belongs
in the design.

A specialist protective security advisory firm built for complex places and high-stakes decisions. We work across threat and risk analysis, crime prevention, protective engineering, and assurance.

Why Core42

$80Bn+

Delivered portfolio

Transport precincts, defence estates, cultural institutions, commercial developments, and public realm — trusted by government clients and retained by their contractors.

Empirical

Incident evidence base

Proprietary terrorism databases, 80+ project case repository, and longitudinal performance studies. Every recommendation is grounded in empirical evidence — not inherited assumptions from the last project.

Proportionate

Not just what to add — what to leave out

We use quantified risk evidence, structured attack analysis, and empirical threat data to determine where protection is justified and where it isn't. Clients consistently tell us the most valuable thing we do is rigorously demonstrate what they can defensibly leave out.

100%

Design integration

Security recommendations delivered in design language, at design decision points — so architects and landscape designers can implement them without a second interpreter. We sit in the meetings, mark up the drawings, and translate threat requirements into spatial parameters the design team can actually use.

What we do

Security advisory structured around the decisions your project actually faces — not a risk register that requires a second round of interpretation before anyone can act. We enter early, stay embedded, and carry protection from the first threat scenario through to built-form verification.

The most defensible security decision is the one made before design locks it in.

A 30-minute diagnostic to identify where your project's security risks actually sit, where evidence-based analysis could prevent disproportionate expenditure, and what decisions need to be made at concept stage — before the rework premium.
