Founder
Leroy M Burton
Founded Critec in 2001. Over three decades shaping security risk practice across CNI, public sector and private enterprise.

A security risk consultancy that protects the systems people rely on — from border infrastructure to datacentres, from custody suites to nuclear power.
Our practice
We specialise in security risk, threat and vulnerability analysis, and security mitigation design for the built environment — across the entire project lifecycle, from conception through completion.
Critec holds BRE licensure to deliver assessments, engineering design and risk analysis under the SABRE security assessment scheme. Every project is delivered under SABRE principles and to ISO 9001 quality standards.
Since 2001 we have delivered programmes across border security, military, government, oil and gas, critical infrastructure, justice, education, transportation, data and retail.
01
Independently delivered to the highest standard. SABRE-aligned, ISO-9001-audited, defensible by design.
02
Ethical practice and uncompromising health and safety culture, applied to every site we set foot on.
03
Strategy gets sharper when more perspectives shape it. We build teams — and recommendations — that reflect that.
04
Cutting-edge methods, tested against emerging threats. We update our tools so you don't have to.
