What Hadrian does

Hadrian is an Amsterdam-headquartered cybersecurity company, founded in 2021 by Rogier Fischer (CEO), Tijl van Vliet (CTO), Maurice Clin (CFO), and Olivier Beg (Head of Hacking), that builds an agentic AI-powered offensive security platform for enterprise customers. The platform is organized around two core products: Atlas, which continuously discovers and monitors external assets (domains, subdomains, certificates, IP addresses, and shadow assets) across the public internet, and Nova, which conducts on-demand autonomous penetration testing of external web applications using AI agents. These run on a proprietary Sense-Plan-Attack methodology implemented via event-driven architecture that breaks tests into composable components, with a fingerprinting layer that contextualizes assets based on application language, version, and known vulnerabilities. Hadrian also released OpenHack, an MIT-licensed open-source AI vulnerability research tool compatible with Claude Code, Codex, and Cursor, and publishes the Exposure Maturity Model, a self-assessment framework benchmarked against 300+ organizations.

The company's go-to-market combines direct enterprise field sales with a channel partner program, supported by product-led growth hooks (free external scans, the Exposure Maturity Model assessment, and Nova's per-test entry point). Pricing is quote-based and undisclosed publicly, structured as annual subscriptions for Atlas and per-pentest entitlements for Nova with multi-year contract terms and professional services add-ons. Hadrian targets enterprise customers across financial services, retail and e-commerce, energy, aviation, technology, and defense/industrial verticals, with named logos including Crédit Agricole Indosuez, Crédit Agricole PFM, Air France-KLM, Siemens Energy, McKesson, Autodesk, Amadeus, Visma, Leroy Merlin, and Damen Shipyards. The company holds SOC 2 Type 2 certification, is recognized in the 2026 Gartner Market Guide for Adversarial Exposure Validation, and has been named a Leader in the GigaOm Radar Report for two consecutive years.

Hadrian has raised approximately €13.9 million across four disclosed funding events: a ~$2.8M round in November 2021 led by Village Global with Slimmer AI, a €10.5M seed in June 2022 led by HV Capital with Picus Capital and Slimmer AI, an undisclosed strategic investment from ABN AMRO Ventures in January 2023, and non-dilutive funding from the EIC Scaling Club in March 2024. The primary operating entity is Hadrian Security B.V. (Netherlands), with Hadrian Security, Inc. (Delaware, USA) serving as the US affiliate. Key technology infrastructure runs on Scaleway cloud hosting in France and the Netherlands. The company maintains 51-100 employees and is privately held with no IPO plans disclosed.

Core offering

Hadrian provides an agentic AI-powered offensive security platform that combines continuous external attack surface management (Atlas) with on-demand agentic penetration testing (Nova). The platform continuously discovers exposed digital assets across the public internet including domains, subdomains, certificates, IPs, and shadow assets, validates what attackers can exploit using autonomous AI agents trained by elite hackers, and delivers prioritized, business-contextualized remediation insights on a 24/7 basis.

Product overview

Hadrian offers an agentic AI-driven offensive security platform composed of two core products: Atlas for continuous external exposure management and Nova for on-demand agentic penetration testing. The platform is sold as individual modules or as the combined Atlas + Nova suite. Atlas continuously discovers and monitors exposed digital assets across the internet including domains, subdomains, certificates, and shadow assets. Nova uses autonomous AI agents to conduct penetration testing of web applications with AI-human collaboration capabilities. Additionally, Hadrian released OpenHack as an MIT-licensed open-source AI vulnerability research tool. The platform combines attack surface management, autonomous hacking, and risk prioritization to emulate how cybercriminals would approach an organization.

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• CrowdStrike: CrowdStrike Falcon Surface is a direct external attack surface management offering embedded within the broader Falcon platform. Comparable because it serves the same enterprise buyer for ASM and exposure validation, though CrowdStrike operates a much broader endpoint, identity, and cloud security portfolio.
• Palo Alto Networks (Cortex Xpanse): Cortex Xpanse (originally Expanse) is one of the leading ASM platforms, directly comparable to Hadrian's Atlas. Comparable on product, customer segment, and use case, though Palo Alto bundles ASM into a much larger security platform and has substantially greater R&D and GTM scale.
• Tenable: Tenable.asm and Tenable Nessus cover vulnerability management and attack surface management — overlapping with both Atlas (ASM) and Nova (vulnerability validation). Comparable on enterprise security buyer and exposure management workflow, though Tenable's strength is traditional vulnerability scanning rather than autonomous pentesting.
• Rapid7: Rapid7 InsightVM and Metasploit Pro cover exposure management and offensive security testing. Comparable to Hadrian on the vulnerability validation and ASM dimensions, though Rapid7's exposure offering is part of a broader SecOps platform including SIEM and incident response.
• Microsoft (Defender External Attack Surface Management): Microsoft Defender EASM is bundled into the broader Defender security cloud and competes directly with Hadrian's Atlas on external attack surface discovery. Highly comparable on enterprise customer base and ASM use case, though Microsoft bundles EASM at low marginal cost alongside Defender, Azure, and Entra ID — a structural pricing threat.
• Wiz: Wiz is a leading cloud security platform that has expanded into cloud-native ASM and exposure management, overlapping with Hadrian's Atlas and cloud exposure visibility modules. Comparable on enterprise cloud-first security buyer, though Wiz's strength is deep cloud workload posture rather than autonomous external offensive testing.

Direct peers

• Bitsight: Bitsight's attack surface management and external risk offerings are directly comparable to Hadrian's Atlas. Both target enterprise security and risk buyers for continuous external exposure monitoring and prioritization, though Bitsight is more established in third-party cyber risk rating while Hadrian leans into autonomous validation.
• XM Cyber: XM Cyber is a direct competitor in exposure validation and attack path management, offering continuous vulnerability validation comparable to Hadrian's Nova. Notable because XM Cyber also appears in Hadrian's customer logo list — illustrating the closeness of the competitive overlap and the strategic ambiguity of that relationship.
• Censys: Censys provides internet-wide asset discovery and attack surface intelligence, overlapping directly with Hadrian's Sense module. Comparable on the external asset discovery and ASM data layer, though Censys's go-to-market leans more toward data/API and threat intelligence buyers rather than autonomous pentesting.

Emerging players

• Axonius: Axonius is a cybersecurity asset management platform that overlaps with Hadrian's asset discovery and exposure management capabilities. Comparable on enterprise security buyer and continuous asset inventory use case, with Axonius focusing on internal and SaaS asset correlation while Hadrian focuses on external attack surface.
