Detailed Review
Hadrian splits its offer into Atlas, which maps and validates the external attack surface continuously, and Nova, which runs pentests with AI agents on demand. The vendor says only validated exposures trigger notifications.
The terms name Hadrian Security B.V., a Dutch private limited company, as the contracting party, and say a different governing law (England and Wales or New York) can be set in the order form.
Atlas for continuous exposure
Atlas tests every change it detects, and the pricing page lists add-ons for mergers and acquisitions assessments and infostealer credential leak detection. Price is based on the total asset count and is given on request.
Nova for pentests
Nova pentests are priced from EUR 1,250 per test excluding VAT, with bundles available, and results map to SOC 2, ISO 27001 and NIS2. The vendor offers a free external scan to start.
Limitations to Consider
Hadrian does not issue supplier security ratings, so it does not replace the scoring side of Bitsight; Orpheus Cyber does. Atlas pricing is not public, and the terms allow English or New York law in the order form, so check what you sign. The agentic testing approach is new and the vendor claims about its depth are not independently checked here.

European security teams that want validated external exposure and flexible pentesting from a Dutch vendor.
