What is an API Vulnerability Scanner?

An API vulnerability scanner is a specialized security tool designed to automatically identify weaknesses and security flaws in Application Programming Interfaces (APIs). Unlike general-purpose web scanners, API vulnerability scanners understand the unique architecture and communication patterns of APIs, enabling them to detect API-specific vulnerabilities that traditional tools miss.

APIs are the backbone of modern software architecture, enabling microservices, mobile applications, and third-party integrations. Each API endpoint represents a potential entry point for attackers, and the growing complexity of API ecosystems makes manual security testing impractical at scale.

SEC Scanner's API vulnerability scanner leverages the Nuclei engine — trusted by security teams worldwide — to comprehensively test your API endpoints against 50+ vulnerability categories. From authentication bypasses to injection attacks, our scanner identifies the security issues that matter most.

Vulnerability Types We Detect

Injection Attacks

SQL injection, NoSQL injection, LDAP injection, and command injection in API endpoints. Attackers can extract, modify, or delete data through unsanitized input parameters.

Broken Authentication

Weak token implementation, missing rate limiting on login endpoints, predictable session IDs, and insecure password recovery mechanisms.

Authorization Bypass

BOLA (Broken Object-Level Authorization) and BFLA (Broken Function-Level Authorization) allowing unauthorized access to data and administrative functions.

Data Exposure

Excessive data exposure, mass assignment, and improper error handling revealing sensitive information in API responses.

SSRF & CSRF

Server-Side Request Forgery allowing internal network access, and Cross-Site Request Forgery enabling unauthorized actions on behalf of authenticated users.

Misconfigurations

Missing security headers, overly permissive CORS policies, verbose error messages, exposed debug endpoints, and default credentials.

Frequently Asked Questions

What is the difference between API vulnerability scanning and API security testing?

API vulnerability scanning focuses on identifying known vulnerabilities and misconfigurations using automated tools, while API security testing is a broader discipline that includes vulnerability scanning, penetration testing, fuzz testing, and manual code review. Scanning is the first step; comprehensive testing goes deeper.

How often should I scan my API for vulnerabilities?

We recommend scanning after every significant code change and at minimum monthly. For critical APIs, daily automated scanning is ideal. SEC Scanner's API integration makes it easy to scan on every deployment.

Can SEC Scanner find zero-day vulnerabilities?

SEC Scanner primarily detects known vulnerability patterns and misconfigurations. While it cannot find truly novel zero-day vulnerabilities, it excels at finding the common security flaws that account for the vast majority of real-world breaches.

Do I need access to the API source code?

No. SEC Scanner performs black-box testing from the outside, just like an attacker would. You only need to provide the API URL. No source code access, credentials, or internal documentation is required.

What formats are scan results available in?

Scan results are available as detailed PDF reports with severity ratings, proof-of-concept evidence, and remediation recommendations. On Professional and Business plans, results are also available via API in JSON format for CI/CD integration.
