API Security Testing.

Test your APIs for real-world risks. FireTail uncovers vulnerabilities, misconfigurations, and risky behavior before attackers do.

Proactive API security testing

FireTail's API security testing tools help you to detect vulnerabilities before they become breaches.

Validate user input

FireTail inspects how APIs handle user input, identifying missing validation, improper data handling, and injection risks. The platform catches unsanitized inputs and unsafe formatting before they lead to exploits like XSS or SQL injections.

Check method handling

FireTail ensures proper HTTP method handling, flagging risky practices such as exposing sensitive data via GET, unauthenticated access to POST/DELETE, or misaligned method-action mappings. It helps you lock down endpoints securely.

Injection risk detection

FireTail uses fuzz testing to simulate malformed inputs and detect vulnerabilities like buffer overflows, crashes, and validation flaws. It actively scans for SQL injection patterns, catching issues before they’re exploited.

Stop parameter tampering

Traditional security testing often overlooks APIs and risks like broken authentication, injection flaws, and tampered parameters. Manual testing can't keep up, and outdated tools aren't built for modern API architectures. FireTail catches these vulnerabilities.

Comprehensive API Security Testing.

FireTail finds the vulnerabilities in your API initiatives before they reach production.

Most APIs go untested

Security testing is often focused on web applications or infrastructure, leaving APIs overlooked. Traditional tools miss API-specific issues, while manual testing doesn't scale across fast-moving dev teams. As a result, insecure endpoints get deployed, and attackers find the gaps before defenders do.

FireTail brings API security testing into every stage

FireTail integrates API security testing into development, deployment, and production environments. It validates input handling, enforces method restrictions, and tests edge cases through built-in fuzzing. FireTail provides the following categories of API security testing:

  • graphQL - testing for graphQL vulnerabilitiesAPI
  • contract testing - check that the API specification matches the endpoints live in production, and monitor for drift
  • CVE detection - across common third-party libraries
  • SSL vulnerabilities - across the server, network and communication path
  • Data exposure - checking for secrets, environment variables and other crucial data that can be accidentally leaked
  • Default login detection - across common third-party libraries and API frameworks
  • Fuzzing - checking for unintended server behavior

FireTail understands API schemas, authentication methods, and business logic, helping detect misconfigurations and logic flaws that generic scanners miss.

Ship safer APIs, without slowing down

FireTail lets teams push faster without sacrificing security. By integrating automated testing and runtime validation, you reduce the chances of introducing critical vulnerabilities into production. Development teams catch mistakes early, while security teams gain assurance that APIs meet organizational standards. The result: better collaboration, fewer incidents, and more resilient applications delivered at speed.
