Hadrian
Agentic offensive security: continuous external exposure mapping plus on-demand AI pentesting.
About
Hadrian is an Amsterdam-based offensive security company founded in 2021 by former ethical hackers Rogier Fischer (CEO) and Olivier Beg (chief hacking officer), together with Maurice Clin. Its pitch is that attackers now move at machine speed while most security teams still run periodic manual pentests, so defenders need an agentic platform that works the same way. The platform has two products that share context: Atlas continuously maps an organization's external digital footprint and deploys purpose-built AI agents to validate which exposures are genuinely exploitable, while Nova provides on-demand agentic penetration testing that builds on what Atlas already learned.
On October 6, 2026, Hadrian raised a $40M Series B co-led by Forgepoint Capital International and SmartFin, bringing total funding to $65M, with participation from HV Capital, Motive Partners, Picus Capital, and Oetker Ventures. The company says the capital will fund expansion across EMEA and the US plus engineering and research hiring. Named customers include McKesson, NBC Universal, and Total Energies. The vendor claims 10x greater visibility into critical exposures, 80% faster resolution, and 5x ROI versus manual pentesting; those figures are company-provided and should be treated as marketing until independently validated. The humans-set-objectives, agents-execute model is the interesting part: analysts move from hunting noise to acting on verified findings.
What it can do
- Atlas: continuous external attack-surface mapping with AI exploitability validation
- Nova: on-demand agentic penetration testing that shares context with Atlas
- Risk prioritization on verified findings, not raw scanner output
- Humans set objectives, AI agents execute continuous testing
- Coverage aimed at insurers, legal firms, and research labs under AI-driven attack pressure
Setup
- Engage Hadrian via hadrian.io and provide your external domains for Atlas mapping.
- Let Atlas continuously discover and validate exploitable exposures on your external footprint.
- Launch Nova for on-demand agentic pentests when you need deeper testing (releases, M&A, compliance).
- Prioritize remediation on verified findings and track exposure reduction over time.
Prerequisites
A Hadrian subscription; list of external domains and authorization for external testing.
