Node REST API Hardener
Systematically hardens Node.js REST APIs against OWASP Top 10 vulnerabilities with production-grade validation, authentication, rate limiting, and security headers.
SupaScore
84.4Best for
- ▸Hardening Express.js APIs against injection attacks, broken authentication, and OWASP Top 10 vulnerabilities
- ▸Implementing production-grade rate limiting and request validation for high-traffic Node.js REST services
- ▸Adding JWT security, CORS policies, and security headers to existing Node.js API codebases
- ▸Auditing Node.js microservices for authentication bypass and authorization flaws
- ▸Building secure API middleware stacks with proper error handling and logging
What you'll get
- ●Complete middleware stack with Zod validation schemas, token bucket rate limiting, JWT verification with proper claims checking, and Helmet security headers configuration
- ●Hardened route handlers with BOLA prevention patterns, centralized error handling that sanitizes responses, and structured logging with PII redaction
- ●Production-ready authentication flows with session management, request/response size limits, and comprehensive input sanitization for all user-controlled data
Not designed for ↓
- ×Frontend security or client-side vulnerability remediation
- ×Database security hardening or SQL injection prevention at the database level
- ×Network-level security like firewalls, DDoS protection, or infrastructure hardening
- ×Mobile app security or native application vulnerability assessment
Node.js REST API codebase (Express, Fastify, etc.) with endpoints, middleware, and authentication flows that need security hardening against OWASP vulnerabilities.
Hardened API code with production-ready security middleware, input validation schemas, rate limiting configurations, and security header implementations with detailed explanations.
