API Security Scanner for Modern Applications

What Is an API Security Scanner?

An API security scanner is a security testing tool designed to analyze application programming interfaces (APIs) for vulnerabilities that could allow unauthorized access, data exposure, or abuse of business logic.

APIs often expose critical business data and functionality, making them a prime target for attackers. Automated scanning helps detect issues early and continuously.

Why API Security Requires Specialized Scanning

• APIs expose direct access to sensitive data
• Authentication and authorization are often complex
• Broken object-level authorization (BOLA) is common
• APIs evolve rapidly with frequent deployments
• Traditional web scanners may miss API-specific flaws

How SmartScanner Scans APIs

1. Discovers API endpoints and parameters
2. Analyzes request and response structures
3. Tests authentication and authorization logic
4. Injects payloads to detect injection and data exposure
5. Validates findings to reduce false positives

API Vulnerabilities Detected by SmartScanner

• Broken Object Level Authorization (BOLA)
• Broken Authentication
• Excessive Data Exposure
• Mass Assignment
• Injection flaws
• Security misconfigurations
• Improper asset management
• Rate limiting and abuse issues

Vulnerabilities are mapped to the OWASP API Security Top 10 where applicable.

These API risks overlap with industry standards such as the OWASP Top 10 , which SmartScanner helps you address automatically.

Supported API Types and Technologies

• REST APIs (JSON / XML)
• Authenticated APIs (JWT, OAuth, API keys)
• Microservices-based architectures
• Backend-for-frontend (BFF) APIs
• Public and private APIs

Who Uses an API Security Scanner?

• Backend and API developers
• Application security teams
• DevSecOps teams
• Organizations exposing public APIs
• Businesses handling sensitive data via APIs
