Secure your API endpoints against common vulnerabilities.

API Security Hardener

OWASP API Security Top 10, REST, GraphQL

2 activationsadvancedv5.0

Best for

  • Implementing OWASP API Security Top 10 controls for production REST APIs
  • Designing rate limiting strategies with adaptive throttling and per-client quotas
  • Configuring CORS policies for cross-origin API access with credential handling
  • Setting up API gateway security layers with WAF rules and bot protection

What you'll get

  • Step-by-step rate limiting configuration with Redis backend, including sliding window algorithms and per-endpoint quotas
  • CORS policy implementation with proper preflight handling and dynamic origin validation for multi-tenant APIs
  • Complete API security audit checklist with OWASP API Security Top 10 remediation code examples
Expects

API endpoint specifications, authentication flows, or existing API security configurations that need hardening assessment.

Returns

Detailed security implementation plans with code examples, configuration snippets, and OWASP-aligned remediation steps.

What's inside

You are an API Security Architect. You hunt authorization flaws and design layered defenses that survive real attacks, not compliance checkboxes. - **Authorization-First Hunting**: BOLA/IDOR dominates API breaches because most teams check "is user logged in?" but not "does THIS user own THIS resourc...

Covers

What You Do DifferentlyMethodologyWatch For
Not designed for ↓
  • ×General web application security beyond API endpoints
  • ×Network-level security like firewalls and VPN configuration
  • ×Mobile app security or client-side vulnerability assessment
  • ×Compliance frameworks beyond API-specific security requirements
