Hadrian
Hadrian provides an agentic AI-powered offensive security platform that continuously maps organizations' external attack surfaces and validates which exposures are genuinely exploitable. Its Atlas product discovers assets like forgotten domains, DNS records, and cloud services, while Nova performs on-demand, AI-driven penetration tests that deliver human-reviewed evidence with reproduction steps. The platform helps security teams prioritize verified risks, with customers reporting 10x faster remediation and 80% fewer triage hours.

Problem
Organizations often lack a current inventory of their internet-facing assets, including forgotten hosts and shadow IT, and may not know which exposures are genuinely exploitable. Periodic manual penetration tests and large volumes of unverified scanner alerts can delay security teams’ identification and remediation of real risks.
Solution
Hadrian combines continuous external exposure management with on-demand, agentic penetration testing in one cloud-based platform. Atlas discovers an organization’s internet-facing domains, DNS records, IPs, certificates, cloud services, and applications, then uses AI agents to test exposures and verify exploitability. Nova performs scoped penetration tests of applications, APIs, and cloud infrastructure by following attacker-like steps to demonstrate impact. The products share asset and testing context, connecting broad attack-surface monitoring with deeper assessment of selected applications. Findings include evidence, reproduction steps, risk context, and remediation guidance so security teams can prioritize verified issues.
Target Audience
Hadrian serves enterprise security teams, including CISOs, security operations, offensive security, and vulnerability management teams, that need continuous visibility into external assets and validated testing of real-world exposures. Its platform is also relevant to organizations seeking on-demand penetration testing for applications, APIs, cloud infrastructure, or compliance assessments.
Features
- Atlas discovers external domains, DNS records, IPs, certificates, cloud services, and applications, including forgotten and shadow IT assets.
- Hourly passive discovery and event-driven tests respond to newly detected assets, changes, and relevant vulnerabilities.
- Agentic AI validates exposures by reasoning about application behavior and chaining weaknesses, rather than relying only on pattern matching.
- Nova runs on-demand penetration tests across web applications, APIs, and cloud infrastructure, including reconnaissance, exploitation, privilege escalation, and cross-account testing.
- Test results show the AI’s reasoning and actions, with request-and-response evidence, reproduction steps, risk context, and remediation guidance.
- Atlas and Nova share attack-surface context; findings can be prioritized by business context and tracked alongside owners, comments, status, and alert rules.
- Cloud-based deployment requires no local installation; Nova tests typically complete within 24–48 hours.
