“Found a leaked Stripe key we'd missed for 6 months. Paid for itself immediately.”

Sample Audit Report
What we find in a typical Vercel project
Real vulnerabilities from anonymized audits. Your report includes exact locations, impact analysis, and step-by-step remediation.
Critical

High

Stripe secret key exposed in client bundle
Payment credentials leaked to browser
Location
lib/stripe.ts:5
Identifier
STRIPE_SECRET_KEY
Found In
/static/chunks/page-a1b2c3.js
Remediation
Move Stripe initialization to a server-only module or API route. Use NEXT_PUBLIC_ prefix only for publishable keys, never secret keys. Rotate your Stripe keys immediately in the Stripe Dashboard.
Server Action callable without authentication
Sensitive action exposed to unauthenticated users
Location
app/actions/user.ts:23
Identifier
updateUserRole
Found In
POST /actions/updateUserRole
Remediation
Verify session and user permissions at the start of every Server Action. Use auth middleware or getServerSession().

Why Hardenly
Generic scanners miss Vercel vulnerabilities
Vercel and Next.js have unique security boundaries between server and client that traditional scanners don't understand. We built Hardenly specifically for the Vercel ecosystem.
Generic Scanners
- OWASP Top 10 (SQL injection, XSS)
- Dependency CVE scanning
- Basic security headers
- Language-agnostic rules
Hardenly
- Server/client boundary leaks
- Middleware bypass patterns
- Server Action validation gaps
- ISR/SSG cache poisoning
- Route handler auth flaws
Common questions
Do you need access to my repository?
For domain scans, we only analyze publicly-accessible responses — no code access needed. For GitHub repos, public repos are cloned and analyzed locally. For private repos, we offer secure GitHub App installation.
What if you don't find any issues?
100% money-back guarantee. If we don't find actionable security issues in your project, you get a full refund. No questions asked.
How is this different from Snyk or Dependabot?
Those tools scan dependencies for known CVEs. We analyze your actual application for Vercel-specific vulnerabilities that don't have CVE numbers — like Server Action validation gaps or middleware bypass patterns.
Can I re-scan after fixing issues?
Yes. Every plan includes 2 verification re-scans per project. Confirm your fixes work before shipping to production.
