Hadrian

Hadrian is a cybersecurity company founded in 2021 that builds an autonomous, agentic AI offensive security platform. Its system continuously discovers internet-facing assets, emulates the behaviour of cybercriminals and validates which exposures are genuinely exploitable, so that security teams can concentrate on real risk rather than theoretical findings. The company operates from the Netherlands and serves customers internationally, with a focus on financial services and technology alongside the cybersecurity sector itself.

The Hadrian Platform combines external attack surface discovery, attack path simulation and autonomous security testing. By simulating the paths attackers would take and confirming which ones work, it aims to give teams 10x visibility into critical risks, save them more than 10 hours a week, and reduce remediation time by 80%.

The company's technical work spans offensive security, agentic AI, attack surface management and vulnerability validation. Hadrian was founded by white-hat hackers whose background lies in breaking systems that were not meant to be broken and in responsible disclosure; the co-founders first met in 2009, at the age of 13, on an online forum. The stated aim of the product is practical: to help security teams save time and prioritise genuine risks.
