Your WAF Is Not Enough.
Proof-Driven Offensive Validation at the API Layer

We test your REST, GraphQL, SOAP, gRPC, and WebSocket APIs not just against the OWASP API Top 10 list, but with real attack chains. We report BOLA, Mass Assignment, and Broken Function Level Auth vulnerabilities with validated proof.

Request API Test

Who is this for?

  • Fintech and Banking applications managing customer data (PII) and payment flows through APIs.
  • SaaS platforms using 3rd-party integrations and microservice architectures.
  • Companies requiring PSD2, Open Banking, or PCI-DSS compliance.

Target API Threat Surface

Automated tools cannot understand authorization logic. Our experts perform full-stack API penetration testing:

BOLA / IDOR (Object-Level Auth Bypass)
Mass Assignment & Injection Chains
Rate Limiting & Token Abuse
SOAP / gRPC / WebSocket (Protocol-Specific Attacks)

Proof-Driven API Testing Methodology

01

API Discovery

Swagger/OpenAPI schemas, WSDL files, gRPC proto definitions, hidden endpoints, and shadow APIs are mapped.

02

Auth Analysis

JWT structures, OAuth flows, and role-based access controls (RBAC) are systematically challenged.

03

Exploit & Proof

Each vulnerability is validated with a real attack scenario and reported as a reproducible PoC.

04

Patch & Retest

Remediation snippets are provided to your dev team, and patches are verified through retest.

Typical API Exploit Findings

  • Broken Object-Level Authorization (BOLA)Accessing /api/v1/users/OTHER_USER_ID with a regular user account to exfiltrate another customer's full PII data.
  • Mass Assignment → Admin PrivilegeSetting a hidden 'role' field to 'admin' in a PUT /profile request to gain full administrator privileges.
  • GraphQL Introspection LeakDiscovering all internal schemas and mutations through an exposed GraphQL introspection endpoint.

Deliverables

Not just a findings list; we deliver executable PoC, Business Impact scores, and developer-friendly remediation code for every vulnerability.

$ curl -H 'Authorization: Bearer USER_TOKEN'

[!] 200 OK — Full user list returned.
[+] BOLA confirmed. Remediation: Implement object-level authz middleware.
