Hadrian is an adversarial exposure validation (AEV) platform, purpose-built to power continuous threat exposure management (CTEM) programs. It is the only AEV platform that combines breadth and depth in a single system: Atlas continuously validates exposures across the full external attack surface, while Nova runs deep, agentic penetration tests against defined web applications and APIs. Most platforms in the category do one or the other. Hadrian does both, with shared context between them.

‍

Where traditional penetration testing runs infrequently and vulnerability scanners flag potential weaknesses without proving exploitability, Hadrian validates continuously, replacing assumption of risk with proof of risk.

‍

Hadrian is named in the Gartner Market Guide for Adversarial Exposure Validation and recognized as a Leader in the GigaOm Radar Report for the third consecutive year, placing it among the most established platforms in the AEV category.

Hadrian's customers are typically mid-market and enterprise organizations with 300 to 10,000 employees, operating complex, distributed IT environments. They tend to share a few common characteristics: a dedicated security function led by a CISO or VP of Security, multi-site infrastructure spanning on-premises and cloud, and a compliance driver such as NIS2, DORA, ISO 27001, or SOC 2.

Hadrian has strongest traction in manufacturing, financial services, energy and utilities, healthcare, transport and logistics, and technology. Customers include McKesson, Siemens Energy, Visma, Amadeus, Breeze Airways, Damen Shipyards, and Crédit Agricole Personal Finance and Mobility.
