## What does Hadrian do?

Hadrian delivers a unified offensive security platform combining continuous external attack surface management (EASM) with on-demand agentic penetration testing.

Atlas: Continuous EASM
Atlas provides reactive breadth via an always-on discovery engine that enumerates domains, IPs, cloud assets, and shadow IT. It reacts to environmental changes in real time, automatically surfacing known-pattern risks. This continuous intelligence maps the external footprint and directly seeds Nova's reconnaissance.

Nova: Agentic Penetration Testing
Nova delivers methodical depth through structured, black-box testing against web applications and REST APIs. Operating via a headless browser to execute client-side JavaScript and handle complex authentication, Nova utilizes a hierarchical architecture: a planner orchestrates specialized AI agents dedicated to specific attack classes like IDOR and SSRF.

To align with architectural complexity, Nova deploys three pentest types with identical agent capabilities, models, and vulnerability coverage:

Micro Nova: Full-depth testing scoped strictly to a specific feature, flow, or release change.

Nova: Testing budgets sized for standard, unified full applications.

Super Nova: Expanded budgets and planner reserves for decoupled architectures, distinct APIs, and multi-tenant trust boundaries.
Production safety is enforced by a tool-call safety check, a browser action firewall, and prompt-injection defenses. Every finding requires mandatory human analyst validation, ensuring zero false positives. Output consists of an audit-ready report mapping to OWASP Top 10, SOC 2, ISO 27001, NIS2, and DORA, with verified findings routed to shared remediation workflows.
