What does Hadrian do?

Hadrian sells two products. ATLAS is continuous external exposure management: discovery of every exposed domain, subdomain, certificate and IP, including shadow assets, with scans typically hourly or after an event trigger. NOVA is on-demand agentic penetration testing.

Validation is the core. Hadrian says its agentic AI simulates attacks and proves exploitability within 15 minutes, using hacker agents trained by ethical hackers, and reports finding on average six verified exploitable exposures per 1,000 scanned assets each week. Ownership is confirmed by machine learning trained by the same team.

Findings arrive with remediation guidance and automatic ticket creation, and Hadrian runs automatic regression tests after remediation. Named integrations are Jira, ServiceNow, GLPI, Slack, Microsoft Teams, SentinelOne, Datadog, Zendesk and HubSpot, plus an API.
