Our Story

Our Story
Our Story
Assess Threat Pty Ltd, previously known as Vardogyir, was founded on the experiences of two security professionals who delivered terrorism and security risk consulting and assessment services to critical infrastructure and major events. The founders were early pioneers in developing terrorism response strategies and plans for crowded places—well before the Australian Government released the national strategy for protecting crowded places.
In 2014, the founders developed and implemented a comprehensive terrorism preparedness strategy for one of the largest mass gathering events in the southern hemisphere. Their work was recognised by two industry awards: Finalist, Australian Security Industry Awards for Excellence (2015) for Special Security Event and Finalist, Outstanding Security Performance Awards (2015) for Outstanding Security Consultant.
In 2015, the founders developed a prototype risk scoring system based on their experience implementing a terrorism preparedness review for stadiums and places of mass gathering in Western Australia. Recognising the limitations of qualitative risk scoring when assessing complex threats such as terrorism, Assess Threat was established to pioneer a data-driven approach to terrorism risk assessment. Leveraging big data analytics, real-time data scraping, and machine learning techniques, Assess Threat released the Terrorism Risk Assessment (TeRA) tool.
As hostile vehicle attacks became increasingly prominent from 2016 onwards, Assess Threat developed Automated Hostile Vehicle Vector Analysis (AHVVA)—a patent-pending technology that uses geospatial data to rapidly assess and model potential hostile vehicle attack vectors.
Assess Threat Pty Ltd holds a NSW Master Security License No. 000105133.
