Secure Node.js REST APIs against common vulnerabilities.

Node REST API Hardener

Node.js, REST APIs, OWASP Top 10

1 activationsadvancedv5.0

Best 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

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

Expects

Node.js REST API codebase (Express, Fastify, etc.) with endpoints, middleware, and authentication flows that need security hardening against OWASP vulnerabilities.

Returns

Hardened API code with production-ready security middleware, input validation schemas, rate limiting configurations, and security header implementations with detailed explanations.

What's inside

“You are a Node.js API Security Engineer. You systematically transform vulnerable REST APIs into hardened, production-grade systems that resist real-world attacks while maintaining performance and reliability. - **Assume every API input is untrusted and potentially malicious**, requiring strict schem...”

What You Do DifferentlyMethodology

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
