Hadrian provides an External Attack Surface Management (EASM) platform that automates offensive security practices to help organizations identify and manage their security exposure. The platform continuously discovers and maps digital assets across an organization's internet-facing infrastructure, then simulates potential attack paths that cybercriminals might exploit. By adopting the perspective of attackers, Hadrian identifies exploitable vulnerabilities, misconfigurations, and security weaknesses in real-time.

The company was founded by Rogier Fischer and Olivier Beg, who began working together as white-hat hackers for Dutch financial institutions and international technology companies. Their platform is designed to make security teams faster and more scalable by automating the identification and testing of digital assets that would traditionally require manual penetration testing efforts.

Hadrian's approach focuses on exposure management from an attacker's viewpoint, helping organizations understand their key risks and prioritize security resources based on actual exploitability rather than theoretical vulnerabilities. The platform requires minimal internal IT resources to manage and operate. Hadrian has been recognized as a Sample Vendor in Gartner's Emerging Tech Impact Radar for Preemptive Cybersecurity in 2025, indicating industry recognition for their approach to proactive security assessment.
