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. For breadth of external exposure, Hadrian is excellent, and it is a three-time leader in attack surface management for a reason. Ares is not an attack surface tool. She does not crawl the internet to inventory your footprint. She goes deep on the targets that matter most, the APIs, web apps, and mobile apps, testing behind authentication for the broken object level authorization and business logic flaws that only show up when you act like a logged-in attacker. Hadrian tells you what is exposed. Ares tells you how far an attacker gets once they are inside your app.
