Your last pentest didn't find what we found.
Hadrian autonomously maps your attack surface, synthesizes exploit chains, and models the financial impact — continuously.
Trusted by Fortune 100 security teams. Findings reported via YesWeHack.
Your attack surface is bigger than you think.
And growing faster than your team can track.
Shadow IT sprawl
Every new SaaS tool, regional microsite, and API integration expands your perimeter. Most of it is unmapped.
Pentests are snapshots
A two-week engagement captures your surface on one day. Your attackers check every day.
Findings without context
A list of CVEs doesn't tell your board what's at stake. Individual findings understate chain risk by 10–100×.
How Hadrian works.
Point
Give us a domain. We handle the rest — no agents to install, no configuration, no onboarding sprint.
Discover
Autonomous agents enumerate subdomains, APIs, credentials, cookies, CORS policies, and misconfigurations across your entire surface.
Synthesize
AI connects individual findings into exploitable chains and calculates financial exposure — the number your board actually understands.
What Hadrian covers.
Autonomous Recon
Subdomain enumeration, DNS mapping, historical URL discovery, API surface identification, credential hunting across public sources.
Attack Chain Synthesis
AI correlates disparate findings — stale DNS assets, misconfigured API policies, session handling flaws — into multi-step exploit chains. Individual findings understate chain risk by 10–100×.
Impact Modeling
GDPR fine calculation, breach notification costs, brand damage estimates, revenue impact — translated into the EUR/USD figure your CISO briefs to the board.
Continuous Monitoring
24/7 perimeter watch with delta alerts. New subdomain registered overnight? New CNAME dangling? You know before an attacker does.
CISO Briefings
Board-ready threat narratives with attack scenario timelines, financial exposure ranges, and remediation priority matrices.
API & Integrations
Webhook alerts, SIEM export, CI/CD security gates. Pipe findings directly into your existing security stack.

“We discovered a critical vulnerability chain across >700 subdomains that exposed the PII, payment methods, and digital wallets of millions of customers — with full read-write access to their accounts.”
Three individually Medium-severity findings across DNS infrastructure, API configuration, and session management. One Critical chain.
Built for engineers who know what they're looking at.
