Rogier Fischer and Olivier Beg met on an online forum in 2009. They were 13. Within a few years they were working as white-hat hackers for Dutch banks and global tech companies, and they watched attackers start using automation and AI while red teams still worked by hand.
In 2021, they founded Hadrian in Amsterdam with Maurice Clin to put that technology on the defenders' side.

We build AI agents that hack the way Rogier and Olivier did, at a scale no human team can match. They map what a company exposes online and try to break in the way an attacker would, around the clock.
We’ve built a continuous learning platform, with each insight feeding back to improve future testing. The hacker perspective continues to drive our product vision and roadmap.

Hadrian is an agentic AI offensive security platform that helps modern security teams prevent breaches by continuously assessing the external attack surface, validating real-world threats, and prioritizing exploitable exposures. Agentic AI powers 10x visibility into your critical risks, cuts through false positives, and provides step-by-step remediation guidance. Organizations reduce time to resolution by 80%, reclaim 10+ hours weekly, and act before attackers can. With Hadrian, you don’t just keep up, you leave your adversaries in the dust.
Security Operations teams and CISOs of medium and large enterprises who struggle with asset inventory, alert validation, and threat prioritization in their work processes.
Unlike traditional tools that run periodic scans and produce high volumes of false positives, Hadrian operates continuously and autonomously. It uses an event-based agentic AI to mimic human hacker behavior, validating risks to ensure they are actually exploitable. This reduces noise and allows teams to focus only on verified threats.
Hadrian empowers Security Operations Center (SOC) teams by shifting from passive vulnerability scanning to active adversarial validation, a process that drastically reduces alert fatigue by filtering thousands of theoretical alerts down to confirmed, exploitable threats. By automating the manual investigation workflow through AI-driven validation and generating undeniable Proof of Concepts (PoC), the platform allows analysts to bypass tedious triage and focus immediately on verified risks. This real-time, event-driven capability integrates seamlessly with existing SIEM and SOAR ecosystems to streamline response times , while simultaneously enriching security posture with proactive threat intelligence—ensuring continuous, high-fidelity visibility across the entire attack surface.
