Cybersecurity

Your API is the most direct path to your data — is it tested for security?

We test your APIs against OWASP API Top 10 and custom business logic attack scenarios, delivering a clear vulnerability report with exploitation proofs and remediation guidance.

The challenges you're facing

REST or GraphQL API exposed publicly handling sensitive data with no penetration testing performed

BOLA (Broken Object Level Authorisation) vulnerabilities letting users access other users' data — the #1 API risk

Mobile app or third-party integrations depending on API security that has never been formally tested

Comprehensive API Security Testing Against OWASP API Top 10

We perform structured penetration testing of REST, GraphQL, and gRPC APIs covering the OWASP API Security Top 10. Testing focuses on authentication and authorisation flaws (BOLA, BFLA), excessive data exposure, rate limiting and resource abuse, injection vulnerabilities, security misconfiguration, and business logic bypasses. We test every endpoint systematically and document findings with working proof-of-concept and prioritised remediation.

Test JWT/OAuth implementation, session management, and all BOLA/BFLA scenarios across user roles.

Business Logic & Injection Testing

Test for data exposure, rate limiting bypass, injection attacks, and application-specific business logic flaws.

Report & Remediation Guidance

Structured CVSS-scored report with endpoint-specific findings, exploit proofs, and API-framework-specific remediation code.

Fintech — Open Banking API

Before

Open Banking API serving 15 mobile applications and 3 enterprise integrations. BOLA testing had never been performed. API documentation was the only security review mechanism.

After

Pentest found BOLA on 6 endpoints allowing access to any user's transaction history and account details. Broken function level authorisation on admin endpoints accessible without admin role.

All critical findings remediated before public launch. API achieved OAuth2 PKCE implementation reviewed and approved by security team. Zero post-launch security incidents.

Frequently Asked Questions

Common questions from enterprise and mid-market teams across India and internationally.

What is BOLA and why is it the most critical API vulnerability?

Broken Object Level Authorisation (BOLA) occurs when an API endpoint uses user-supplied IDs to access objects without verifying that the requesting user owns or has permission to access that specific object. For example, changing a URL from /api/accounts/123 to /api/accounts/124 to access another user's account. It's #1 in OWASP API Top 10 because it's extremely common and allows direct data theft.

Do you test GraphQL APIs differently from REST?

Yes. GraphQL has unique attack surfaces: introspection exposure (revealing your entire schema), nested query DoS attacks, batching abuse, and directive injection. We test GraphQL-specific risks in addition to standard authentication and authorisation checks.

Can you test APIs that require authentication?

Yes. We work with test accounts at multiple privilege levels (user, admin, read-only) to test authorisation boundaries. You provision test credentials and we test systematically without touching production user data.

How do you test APIs used by a mobile application?

We use a proxy (Burp Suite) to intercept mobile app API traffic, which lets us see all requests including those not in documentation. We then test each discovered endpoint systematically. Certificate pinning bypass is included where applicable.
