Hadrian raises $40M for continuous offensive-security testing

Hadrian sells security software that continuously examines an organization’s internet-facing footprint, verifies which weaknesses an attacker could exploit and helps security teams decide what to fix first. The Amsterdam-founded company has raised $40 million, bringing its total funding to $65 million.

The workflow begins with Atlas, which inventories systems exposed to the internet. Hadrian’s AI agents then probe possible weaknesses, while security staff set the mission and retain key decisions. A separate on-demand product can run a deeper penetration test using the context already collected, so teams don’t have to restart the investigation.

That shared context is the product’s practical distinction. Hadrian argues that scanners generate more findings than teams can investigate and that many security teams still rely on manual penetration testing. Its platform combines continuous exposure monitoring with automated offensive testing, letting customers move from finding an exposed asset to validating an attack path and prioritizing the repair.

Founded in 2021 by Rogier Fischer, Olivier Beg and Maurice Clin, Hadrian says it works with companies in the United States and Europe, naming McKesson, NBCUniversal, Francisco Partners, TotalEnergies, Amadeus, Leroy Merlin and Damen Shipyards as customers. The company claims its technology provides 10 times greater visibility into critical exposures, cuts resolution time by 80% and delivers five times the return of manual testing.

Forgepoint Capital International and Smartfin co-led the financing, with existing backers HV Capital, Motive Partners, Picus Capital and Oetker Ventures participating. Hadrian plans to use the capital to expand across Europe, the Middle East, Africa and the United States while adding engineers and researchers.
