Hadrian
Hadrian is an Amsterdam offensive security company whose Atlas platform maps a company's external attack surface around the clock and whose Nova agents run on-demand AI penetration tests from €1,250 per test.
Security teams at mid-size and large companies with a sprawling internet-facing footprint that want exposures found, validated as exploitable, and retested whenever something changes, plus compliance-ready pentests mapped to SOC 2, ISO 27001, and NIS2.
Teams that only need one annual pentest of a single app, and buyers who want deep internal network or source code testing, since Hadrian centers on the external attack surface.
Verdict
Hadrian pairs two products that most vendors sell separately. Atlas finds internet-facing assets, including ones the security team did not know about, and checks which exposures an attacker could use. Nova runs agentic pentests on demand and feeds what it finds back into Atlas. Hadrian says more than 1,000 companies use it, including McKesson, NBCUniversal, and Amadeus, and it raised a $40 million Series B in October 2026. The published per-test price is rare in this market. For teams that want to test as often as they ship, Hadrian is an easy recommendation.
Score Breakdown
These scores cover how well Hadrian maps the attack surface, how deep its AI pentests go, how well it proves findings are real, and how clear its pricing is, and then how it does as a company on innovation, communication, pricing, and contract terms.
Who Uses Hadrian, Where It Fits on Price, and Its Competitors
Hadrian sells to security teams at banks, manufacturers, healthcare companies, and private equity firms, which use it to assess portfolio companies and acquisitions. Most start with Atlas for continuous external exposure management and add Nova when they need a pentest for a release, an audit, or a customer. Hadrian was founded in 2021 by former ethical hackers Rogier Fischer and Olivier Beg with Maurice Clin, has raised $65 million in total, and has about 90 people.
On price, Nova pentests start at €1,250 per test excluding VAT, with bundles available, and Atlas is quoted. Its closest competitors are XBOW, Ethiack, RunSybil, and Terra Security.
