Hadrian is an agentic AI offensive security platform for external exposure management. It continuously discovers internet-facing assets, including shadow IT and forgotten subdomains, emulates attacker behaviour and validates which exposures are truly exploitable. The platform is built around the Continuous Threat Exposure Management (CTEM) framework and is delivered through modules for attack surface management (Atlas), on-demand agentic penetration testing (Nova), asset discovery (Sense), exploit validation (Attack) and risk prioritization (Plan). Hadrian also offers infostealer and dark web credential monitoring, DNS misconfiguration monitoring, cloud exposure visibility across AWS, Azure and GCP, and look-alike domain detection. Every verified finding includes proof-of-concept evidence and remediation guidance, and results map to frameworks including SOC 2, ISO 27001 and NIS2. The platform is used by security teams at more than 300 enterprises and includes an API for integration with existing tooling. Hadrian is named a Representative Vendor in the 2026 Gartner Market Guide for Adversarial Exposure Validation.
