vlayer - HIPAA Compliance Scanner
Automated security scanning for healthcare applications. Detect PHI exposure, fix vulnerabilities, and generate audit-ready compliance reports.
What is vlayer?
vlayer is a CLI tool that scans your codebase for HIPAA compliance issues. It's designed for healthcare startups and developers building applications that handle Protected Health Information (PHI).
Key capabilities:
- Scan for 50+ security vulnerabilities and PHI exposure patterns
- Auto-fix common issues with one command
- Generate professional audit reports (HTML, PDF, JSON)
- Detect your tech stack and provide tailored recommendations
- Create cryptographic audit trails for compliance documentation
Quick Start
# Install
npm install
npm run build
# Scan a project
node dist/cli.js scan /path/to/your/project
# Generate HTML report
node dist/cli.js scan /path/to/project -f html -o report.html
# Auto-fix issues
node dist/cli.js scan /path/to/project --fix
# Generate audit PDF
node dist/cli.js audit /path/to/project --generate-reportFeatures
1. Vulnerability Detection
Scans for 50+ security patterns across 5 HIPAA compliance categories:
| Category | What it detects |
|---|---|
| PHI Exposure | SSN/MRN in code, PHI in logs, localStorage, URLs |
| Encryption | Weak crypto (MD5, DES), disabled SSL/TLS, HTTP URLs |
| Access Control | SQL injection, XSS, CORS wildcards, hardcoded credentials |
| Audit Logging | Missing logging framework, unlogged PHI operations |
| Data Retention | Bulk deletes without audit, missing retention policies |
View all detection patterns
PHI Exposure (18 patterns)
- Social Security Numbers (XXX-XX-XXXX)
- Medical Record Numbers (MRN patterns)
- Date of Birth handling
- Diagnosis codes (ICD-10)
- PHI in console.log statements
- PHI in localStorage/sessionStorage
- Patient data in URLs
- Unencrypted patient contact info
Security Vulnerabilities (20+ patterns)
- Hardcoded passwords and secrets
- API keys (generic, Stripe, AWS)
- Database URIs with credentials
- SQL injection (template literals & concatenation)
- innerHTML without sanitization
- eval() and Function constructor
- dangerouslySetInnerHTML in React
Infrastructure Issues
- HTTP URLs for PHI transmission
- Disabled SSL/TLS verification
- CORS wildcard origins
- Sessions without expiration
- Missing authentication checks
2. Auto-Fix (--fix)
Automatically remediate common vulnerabilities:
node dist/cli.js scan ./my-app --fix| Issue | Auto-Fix Applied |
|---|---|
| SQL injection | Convert to parameterized query query('SELECT * FROM users WHERE id = ?', [id]) |
| Hardcoded password | Replace with process.env.PASSWORD |
| Hardcoded API key | Replace with process.env.API_KEY |
| HTTP URL | Upgrade to HTTPS |
| innerHTML | Replace with textContent |
| PHI in console.log | Comment out with review marker |
Example output:
✔ Scan complete. Found 29 issues.
✔ Applied 8 automatic fixes.
Changes by file:
src/api/users.ts
Line 45: SQL injection → parameterized query
Line 89: Hardcoded password → process.env.DB_PASSWORD
src/utils/logger.ts
Line 12: PHI in console.log → commented out3. Stack Detection
vlayer automatically detects your tech stack and provides personalized code examples:
Stack detected:
Framework: Next.js
Database: Supabase
Auth: Supabase AuthSupported technologies:
| Type | Detected |
|---|---|
| Frameworks | Next.js, React, Vue, Nuxt, Angular, Express, Fastify, NestJS |
| Databases | Supabase, Firebase, PostgreSQL, MySQL, MongoDB, Prisma, Drizzle |
| Auth | NextAuth, Supabase Auth, Firebase Auth, Auth0, Clerk, Passport |
Stack-specific recommendations include:
- Next.js + Supabase: Server Components for PHI, Row Level Security (RLS), middleware protection
- Express + PostgreSQL: express-session with Redis, parameterized queries
- React + Firebase: Firestore Security Rules, Admin SDK for PHI
4. Remediation Guides
Each finding includes a detailed remediation guide with:
- HIPAA Impact: Why this matters for compliance
- Multiple fix options: Different approaches with trade-offs
- Code examples: Copy-paste ready solutions
- Documentation links: Official resources
The guides are personalized to your stack - if you're using Supabase, you'll see Supabase-specific code examples, not generic SQL.
5. Audit Trail & PDF Reports
Generate compliance documentation with cryptographic verification:
# Run scan with fixes (creates audit trail)
node dist/cli.js scan ./my-app --fix
# Generate PDF report
node dist/cli.js audit ./my-app --generate-report --org "Healthcare Inc" --auditor "Jane Smith"Audit trail includes:
| For Auto-Fixed Issues | For Manual Review Items |
|---|---|
| Code before & after | Status: "Pending human review" |
| SHA256 file hashes | Assigned responsible party |
| Timestamp of change | Suggested deadline by severity |
| HIPAA reference resolved | Full finding details |
PDF Report sections:
- Cover Page - Project info, scan statistics
- Executive Summary - Remediation rate, risk breakdown
- Fix Evidence - Cryptographic proof of each change
- Manual Reviews - Pending items with deadlines
- Verification Page - Report hash, signature fields
Report Examples
HTML Report
The HTML report includes:
- Summary cards with severity counts
- Stack detection section with tailored recommendations
- Each finding with code context and line highlighting
- Expandable remediation guides with code examples
- Auto-fixable badge on issues that can be fixed automatically
