Web Application & API Penetration Testing Services

We ingest your OpenAPI, Swagger, Postman collections, and WSDL definitions. Our engineers map all declared and hidden shadow API routes, establishing a comprehensive Role-Based Access Control (RBAC) matrix across User, Tenant Admin, Support, and Super Admin tiers.

Rigorously evaluating identity mechanisms: OAuth2, OpenID Connect, SAML, and JSON Web Tokens (JWT). We test token signature tampering, algorithm confusion attacks (RS256 to HS256), session fixation, and refresh token replay vulnerabilities.

The core focus of our assessment. We manually execute cross-tenant object manipulation (BOLA/IDOR), test mass-assignment during profile updates, and probe complex multi-step workflows (e.g. ecommerce checkout, money movement, voucher redemptions) for race conditions.

Testing server-side parsers and backend data layers against sophisticated injections. We evaluate Server-Side Request Forgery (SSRF) targeting internal cloud metadata (IMDSv2), NoSQL injection in MongoDB/Elastic, blind SQLi, and template injections.

We provide your development team with runnable Postman collections, exact cURL commands, and framework-specific patch snippets. Our engineers conduct a live technical debrief, followed by a complimentary 30-day retesting window.

Why do automated DAST scanners miss critical API vulnerabilities like BOLA and IDOR?

Automated DAST tools lack contextual understanding of your business logic. A scanner knows how to inject a single quote to test for SQL injection, but it cannot know that changing 'account_id=1024' to 'account_id=1025' in a banking endpoint should only succeed if the authenticated user owns account 1025. Uncovering Broken Object-Level Authorization (BOLA) requires skilled human ethical hackers to analyze authorization flows, map multi-user permissions, and chain stateful requests.

Do you test GraphQL, gRPC, and WebSocket APIs in addition to standard REST APIs?

Yes. Our engineers specialize in modern API architectures. For GraphQL, we test schema introspection controls, nested query Denial-of-Service (DoS), batch query authorization bypasses, and field-level permissions. For gRPC and WebSockets, we reverse-engineer protocol buffer schemas, inspect binary payloads, and evaluate real-time bidirectional message authorization.

Should testing be conducted on our staging environment or directly on production?

Testing on a staging environment that mirrors production architecture and configuration is ideal because it allows deeper exploitation without risking operational data. However, if staging does not accurately reflect production WAF rules, third-party integrations, or database scale, we safely conduct penetration testing on production during agreed off-peak hours under strict rate-limiting and non-destructive Rules of Engagement.

Can your API penetration testing report satisfy NPCI UPI and RBI banking audits in India?

Yes. We have deep experience evaluating Indian FinTech, payment aggregators, and core banking APIs. Our reports explicitly evaluate NPCI UPI procedural guidelines, payload encryption, HMAC signature verification, device binding, and RBI Master Direction mandates, providing the exact technical evidence required by CERT-In and RBI auditors.

How do you assist our engineering team in resolving reported API flaws?

We do not simply hand over a PDF report and walk away. We deliver a runnable Postman collection that your engineers can import to instantly reproduce the exact vulnerability in their local debugger. We also provide framework-specific code snippets (e.g. implementing tenant-scoped database queries in Prisma/Hibernate/SQLAlchemy) and host a live technical debrief with your lead architects.
