API Security Sentinel
Advanced API security testing with intelligent fuzzing, authentication bypass detection, and automated vulnerability discovery.
What is API Security Sentinel?
The API Security Sentinel is your automated API security expert that performs comprehensive security testing across REST, GraphQL, and gRPC APIs. It goes beyond basic scanning to intelligently fuzz endpoints, test authentication flows, discover hidden APIs, and validate that your security controls actually work under attack.
Problems It Solves
APIs Are the New Attack Surface
Modern applications are API-first. Every endpoint is a potential entry point for data breaches, account takeovers, and unauthorized access. API vulnerabilities consistently rank in OWASP Top 10.
Broken Authentication Everywhere
JWT vulnerabilities, session fixation, missing rate limits, and weak password policies plague APIs. Attackers exploit these flaws to gain unauthorized access at scale.
Authorization Logic Flaws
Horizontal privilege escalation (IDOR), vertical privilege escalation, and missing authorization checks allow users to access or modify data they shouldn't touch.
Hidden & Shadow APIs
Undocumented endpoints, deprecated APIs still in production, and internal APIs exposed publicly create massive security blind spots.
How API Security Sentinel Works
Intelligent API Fuzzing
Generates thousands of attack payloads tailored to your API schema. Tests every parameter for SQL injection, XSS, command injection, XXE, and more.
Authentication & Authorization Testing
Tests auth flows with missing tokens, expired tokens, tokens from other users, and privilege escalation attacks. Validates RBAC, ABAC, and permission systems.
Business Logic Exploitation
Discovers race conditions, price manipulation, quantity exploits, and workflow bypass vulnerabilities that only appear through business logic testing.
API Discovery & Mapping
Discovers undocumented endpoints, shadow APIs, and deprecated endpoints still in production. Maps your complete API attack surface.
User Benefits
Prevent Data Breaches
Find API vulnerabilities before attackers exploit them to exfiltrate customer data, financial information, or PII.
Validate Security Controls
Prove your authentication, authorization, rate limiting, and input validation actually work—not just in theory.
Continuous API Security
Scan every API change in CI/CD. Catch new endpoints, parameter changes, and auth bypasses immediately.
Comprehensive Coverage
Test REST, GraphQL, and gRPC APIs with protocol-specific security checks. Support for OpenAPI, Swagger, and GraphQL schemas.
Fast Remediation
Get exact requests/responses that trigger vulnerabilities. Developers can reproduce and fix issues in minutes.
Compliance Evidence
Demonstrate API security testing for PCI-DSS, SOC2, and other compliance frameworks requiring regular security assessments.
Real-World Use Cases
GraphQL Authorization Bypass
Found 15 GraphQL queries bypassing authorization checks. Pagination parameters allowed fetching any user's private data—fixed before production launch.
IDOR in REST API
Discovered IDOR vulnerability allowing users to access others' payment information by changing account IDs. Prevented PCI-DSS violation.
Business Logic Race Condition
Identified race condition in discount code redemption. Attackers could apply same code 10+ times through parallel requests, reducing order total to $0.
