TNK is an Australian cybersecurity firm that focuses on the human dimension of cybersecurity. The company was founded by a team of experts drawn from cybersecurity, education, and research disciplines, with a combined experience of over 50 years and a track record of delivering more than 250 projects across varying types and sizes. TNK's core approach applies human factors knowledge to cybersecurity challenges, with the goal of helping individuals and organisations reduce their exposure to digital threats through behavioural understanding rather than purely technical controls. A central product of the company is the Behavioural Assessment Engine, a platform designed and developed by TNK to analyse individuals' digital behaviour. The platform identifies both strengths and vulnerabilities in how people interact with digital environments, enabling targeted interventions based on behavioural data. TNK's methodology draws on research from human factors science, integrating it with cybersecurity practice to address the role that human behaviour plays in organisational security posture. The company's work spans assessment, project delivery, and consultancy, serving organisations seeking to understand and manage the human element of their cybersecurity risk.
