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×.
The Pipeline
From Surface Discovery to Hardened Posture
How Hadrian works
Map your entire attack surface
AI agents enumerate subdomains, APIs, credentials, cookies, CORS policies, and misconfigurations. We discover what your pentest missed — in hours, not weeks.
Chain findings into critical exploits
Individual findings understate risk by 10-100x. Our AI correlates disparate issues into multi-step attack chains with CVSS scoring and financial exposure modeling.
INDIVIDUAL FINDINGS
AI correlation
Fix it. Prove it. Automatically.
AI agents apply fixes directly — CSP tightening, header hardening, session cookie fixes, dangling DNS cleanup — with regression tests verifying each fix holds. Posture score: before and after.

APPLIED FIXES
What Hadrian covers.
Autonomous Recon
Subdomain enumeration, DNS mapping, historical URL discovery, API surface identification, credential hunting across public sources.
Pricing
Automated security coverage for every stage.
Start with AI-powered surface monitoring, then scale into Deep Scans, authenticated testing, and compliance workflows as your security posture matures.
Scout
AI-powered surface monitoring for your external footprint.
billed annually
- 1 web property
- Unlimited subdomain discoveryHadrian discovers all visible subdomains under your verified web property. Scout limits cadence and depth, not discovery.
- 1 Sentinel run / monthAI-assisted reconnaissance that maps your surface, detects drift, and flags new exposures automatically.
- Clear issue summaries
- Self-serve setup
Core
Continuous offensive testing — replaces your annual pentest.
billed annually
Everything in Scout, plus:
- Unlimited subdomain discoveryDiscovery stays uncapped; Core adds deeper analysis, authenticated testing, and more frequent monitoring.
- 2 Deep Scans / monthFull-scope AI offensive security — attack surface discovery, exploit-chain reasoning, evidence-backed findings, and remediation priorities.
- 6 Sentinel runs / monthDrift checks plus safe retesting of known vulnerabilities. Remediations are verified and new exposures don't wait for the next engagement.
- Authenticated testingTesting behind login walls — authorization flaws, privilege escalation, session handling, and business logic risks.
- Executive PDF report
- Automated remediation guidance
- Slack + email alerts
- Fully automated coverageCore does not include human analyst review. Enterprise adds review, custom operating model, and SLA commitments.
Pro
Multi-environment coverage with compliance and integrations.
billed annually
Everything in Core, plus:

- 4 Deep Scans / month
- 12 Sentinel runs / month
- Compliance mappingMap findings to SOC 2, ISO 27001, PCI DSS, MAS TRM, and other frameworks your auditors require.
- Priority alerts
- Dedicated CSM
Enterprise
Custom coverage, human review, and SLA commitments.
Everything in Pro, plus:
- Unlimited web properties
- Custom authorization scopeSubsidiaries, mobile apps, private deployments, and special environments are scoped explicitly.
- Custom scan cadence
- Mobile app scanningWe decompile your Android and iOS apps to check for vulnerabilities, hardcoded secrets, insecure data storage, and certificate pinning issues.
- Multi-domain & subsidiary coverage
- Phishing campaignsAI-generated phishing simulations with open/click/credential tracking and behavioural analytics.
- Threat intelligence feedCurated threat intel correlated against your monitored attack surface.
- Cloud posture scanReview cloud accounts across AWS, GCP, or Azure for misconfigurations, overly permissive IAM, and exposed storage.
- SIEM & webhook integrationsPush high-signal findings into Splunk, Sentinel, or your team's existing tools.
- Human review layerVantalab analyst review for scoped engagements, executive interpretation, and custom assurance needs.
- Private edge deploymentOn-premise or air-gapped Axiom Edge node for customers who can't let raw evidence leave their environment.
- Custom SLA & dedicated team
One engagement. One chain. Billions in exposure.
“Hadrian discovered a critical vulnerability chain across 739 subdomains that exposed the PII, payment methods, and digital wallets of millions of customers — with full read-write access to their accounts. Their existing pentest vendor had found nothing.”
Three individually Medium-severity findings across DNS infrastructure, API configuration, and session management. One Critical chain. Their existing pentest vendor had found none of them.
Built for engineers who know what they're looking at.
