Secure Your APIs with Real-Time Monitoring
APIWatcher detects security events, monitors credentials, and provides AI-powered solutions to keep your APIs secure and performant.

How APIWatcher Secures Your Infrastructure
From detection to remediation, we provide comprehensive security monitoring for your APIs
Security Events Monitored
- Insecure Communications (HTTP)
- Unauthorized Access Attempts
- Credential Leaks in API Traffic
- Rate Limiting Events
- Missing CSRF Protection
- Sensitive Information Exposure
- Missing Authentication
Security Alerts
API key “sk_live_...” detected in query parameters to /api/payment/process
Database credentials detected in JavaScript bundle at /js/main.js
Coding Agent Context
Stripe API key was exposed in client-side code, creating a significant security risk.
Payment processing logic implemented on the client-side instead of server-side, resulting in API key exposure in browser-accessible code.
- Revoke the exposed API key immediately
- Move payment processing to server-side code
- Store API keys in environment variables
Why Network-Level Analysis Beats Codebase Scanning
APIWatcher monitors API calls at the network level, delivering real-time security insights when they matter most.
Why Codebase Analysis Falls Short
- Runtime blind spots
Static scanning misses security flaws only visible in production runtime
- AI coding risks
Cannot reliably detect hardcoded secrets in large AI-generated codebases
- Third-party blind spots
Misses security issues in external APIs and dependencies
- Complex integration
Requires extensive setup and CI/CD integration
Why Network Monitoring Excels
- Real-time protection
Catches threats the moment they occur in live API traffic
- Dynamic insights
Observes live API interactions that static tools miss
- Third-party visibility
Monitors all external service calls in your application
- Effortless integration
Installs in minutes with a simple JavaScript snippet—no code changes needed
