Advanced API Security Testing

Comprehensive detection and testing for every API attack vector

01
Authorization

BOLA & Broken Authorization Testing

Sophisticated broken object level authorization testing with automatic object ID enumeration, cross-user access attempts, and tenant isolation validation. Full privilege escalation and function-level access control testing.

  • BOLA/IDOR testing with automatic object ID enumeration
  • Cross-tenant access and UUID prediction tests
  • Admin function access and role escalation checks
  • Mass assignment and hidden field detection

Discovery

Automatic Endpoint Discovery & Fuzzing

Crawl and discover all API endpoints including hidden and undocumented routes. Smart parameter fuzzing with type-aware payloads for injection flaws, XSS, path traversal, and business logic errors.

  • Auto-discover hidden and undocumented endpoints
  • OpenAPI/Swagger spec import and traffic analysis
  • Type-aware fuzzing payloads for all parameter types
  • Shadow API and outdated version detection
03
Authentication

Multi-Auth & Injection Testing

Test APIs with Bearer tokens, API keys, OAuth 2.0, JWT, Basic Auth, and custom authentication schemes. Comprehensive injection vulnerability detection including SQL, NoSQL, and command injection.

  • JWT manipulation and session fixation testing
  • OAuth 2.0 and API key weakness detection
  • SQL, NoSQL, and command injection testing
  • Rate limiting bypass and resource exhaustion checks

OWASP API Security Top 10 2023 Coverage

Comprehensive coverage of all API security risks with automated exploitation and validation

Critical Risks

  • API2: Broken Authentication (JWT, session fixation)
  • API5: Broken Function Level Authorization

High Risks

  • API3: Broken Object Property Level Authorization
  • API4: Unrestricted Resource Consumption
  • API6: Unrestricted Access to Sensitive Business Flows
  • API7: Server Side Request Forgery (SSRF)

Medium Risks

  • API8: Security Misconfiguration (CORS, verbose errors)
  • API9: Improper Inventory Management (shadow APIs)
  • API10: Unsafe Consumption of Third-Party APIs

Frequently Asked Questions

Everything you need to know about TigerGate API Security

TigerGate API Security tests REST, GraphQL, and SOAP APIs. For REST it imports OpenAPI/Swagger specs or auto-discovers endpoints via traffic analysis. For GraphQL it runs introspection queries to map the schema before testing query depth attacks, batching abuse, and field-level authorization. For SOAP it parses WSDL files and tests for XML injection, XXE, and WS-Security weaknesses.
The scanner uses non-destructive, read-oriented probes by default and never submits data that would alter application state. Fuzzing payloads are carefully scoped to observe error responses rather than trigger writes. You can also point scans at a staging environment — no installation on the target server is required, only a reachable endpoint and valid credentials.
TigerGate accepts Bearer tokens, API keys, OAuth 2.0 flows, JWT tokens, Basic Auth, and custom header schemes. It also tests the authentication mechanisms themselves — checking for JWT alg:none bypasses, session fixation, weak API key entropy, and OAuth 2.0 scope misconfigurations.
All ten risks are covered: BOLA/IDOR (API1), Broken Authentication (API2), Broken Object Property Level Authorization (API3), Unrestricted Resource Consumption (API4), Broken Function Level Authorization (API5), Unrestricted Access to Sensitive Business Flows (API6), SSRF (API7), Security Misconfiguration including CORS (API8), Improper Inventory Management and shadow APIs (API9), and Unsafe Consumption of Third-Party APIs (API10).
A full scan typically completes in under 15 minutes for APIs with up to a few hundred endpoints. The scanner auto-discovers undocumented and shadow endpoints, runs over 10,000 test cases, and returns a prioritized findings report with remediation guidance — all fully automated with no SDK or agent installation on the target.
Yes. TigerGate exposes a REST API (POST /api/scans) that integrates with any CI/CD system — GitHub Actions, GitLab CI, Jenkins, CircleCI, and others. You can set severity thresholds to fail pipelines on critical findings, ensuring API security gates are enforced on every deploy. A 14-day free trial is available with no credit card required.
