FifthDomain Information

FIFTH DOMAIN is a Cyber Force Intelligence company based in Canberra, Australia. We build simulations and evaluations that help organisations understand cyber capability, human and AI. Since 2015 we have examined how operators behave under pressure. Since 2024 we have applied the same discipline to AI systems. We do not make deployment decisions. We produce the intelligence on which an accountable person decides. Two products carry that work. XORCISE shows how a cyber AI agent performs and behaves in cyber work, so model builders and agent developers can see what needs to improve and guide their own development. 5D.PRO gives employers and teams evidence of people's demonstrated cyber skills for hiring and development decisions. We work with AI developers, enterprises deciding where AI belongs in cyber operations, and government and Defence building the capability their missions require. We publish our cyber AI research at xorcise.ai so others can examine the work. fifthdomain.co
