Ares vs Hadrian
Two ways to think like an attacker: outside-in, and deep-in.
This page compares Hadrian: an attack surface management platform that maps your internet-facing footprint and runs autonomous external pentests, with Ares, an API-first platform that goes deep behind authentication into the flaws that matter most. Ares also provides attack surface management and discovers Shadow AI running in your environment, with authorized testing of supported AI services and applicable MITRE ATLAS coverage.

What each is built for
Map the surface, or breach the app.
Both think like an attacker. The difference is depth: Hadrian inventories what is exposed on the outside, while Ares proves how far an attacker gets once they are inside your app.
What Hadrian is built for
Hadrian made its name mapping the outside of your company. Its platform continuously discovers every internet-facing asset you have: the forgotten subdomains, expired certificates, and shadow infrastructure attackers find first, and with Nova it now runs autonomous external pentests against that surface. It is a three-time leader in attack surface management for a reason.
What Ares is built for
Ares combines attack surface management and Shadow AI discovery with deep web, API, mobile, and supported AI testing. Assess authenticated boundaries, authorization, and business logic, with applicable MITRE ATLAS coverage for AI techniques.

Decision snapshot
A quick read on which fits your goal.
Compare where Hadrian fits for mapping and testing your external attack surface, and where Ares fits for deep application-layer testing behind authentication.
Hadrian may be a fit if…
Your priority is discovering unknown internet-facing assets.
You need continuous mapping of shadow infrastructure and subdomains.
External exposure breadth matters more than app depth.
Ares may be a fit if…
You need application testing, Shadow AI discovery, and attack surface management.
APIs and mobile backends are your primary risk surface.
You need deep BOLA and OWASP API Top 10 coverage.
You need deep BOLA and business logic testing behind authentication.

Key differences
Where the difference actually shows up.
Hadrian and Ares overlap on autonomous, attacker-minded testing. These are the areas where depth separates them.
Surface breadth vs app depth
Hadrian maps and tests the outside of your footprint. Ares goes deep behind authentication into the flaws that only show up once you are inside the app.
Behind authentication
Ares tests with real credentials and roles for the access-control flaws an external surface scan never reaches.
Mobile-to-API attack chains
Ares follows the real attacker path from a mobile app into its API backend: a surface Hadrian does not test.
Defined targets, not discovery
Ares combines attack surface management with deep, authenticated application testing and Shadow AI discovery. Supported AI assessments include applicable MITRE ATLAS coverage.
