Everything You Need to Secure Financial APIs- Instantly

API Discovery & Shadow Detection

Uncover every API across banking systems, payment gateways, and legacy apps. Detect undocumented or shadow endpoints before they expose sensitive data.

API Discovery & Shadow Detection

Sensitive Data & Compliance Protection

Automatically detect PII, account numbers, and card data in responses. Generate compliance-ready reports for PCI DSS, GDPR, and RBI regulations.

Sensitive Data & Compliance Protection

Transaction Integrity Testing

Simulate real-world edge cases like duplicate withdrawals, overdraft bypass, or balance mismatches. Catch business logic flaws before they result in fraud or financial loss.

Transaction Integrity Testing

Access Control & Token Validation

Validate authentication, authorization, and role-based permissions. Ensure encryption of sensitive fields and verify token expiry, revocation, and replay protection.

Beyond the Basics: End-to-End API Security

From performance under pressure to third-party dependencies and real-time fraud detection, secure every layer of your financial APIs.

1

Performance & Scalability

Test APIs under real-world banking loads like trading spikes, payroll runs, and UPI surges. Ensure systems remain reliable and responsive when transaction volumes peak.

2

Third Party & Integration Risk

Monitor APIs from payment gateways, KYC providers, and credit bureaus. Catch failures or vulnerabilities in dependencies before they disrupt critical services.

3

Threat Monitoring & Fraud Detection

Detect anomalies like unusual API traffic, token misuse, or repeated failed OTP attempts in real time. Integrate alerts with SIEM and fraud prevention systems to take immediate action.

Everything You Need to Know, All in One Place

Discover quick and comprehensive answers to common questions about financial services API testing.

How do you protect against fraud and business logic attacks?+
We simulate real-world fraud scenarios like duplicate withdrawals, overdraft bypass attempts, and balance manipulation. Our transaction integrity testing catches business logic flaws, validates idempotency, and prevents financial loss before fraudulent transactions can occur.
How do you keep APIs safe from external threats?+
We continuously monitor API traffic for suspicious patterns, injection attacks, and unauthorized access attempts. Real-time threat detection blocks malicious requests, validates authentication tokens, and prevents external attackers from exploiting vulnerabilities in your financial APIs.
What safeguards are in place for third-party integrations?+
We monitor APIs from payment gateways, KYC providers, credit bureaus, and other third-party services. The system detects failures, vulnerabilities, and disruptions in dependencies, alerting you immediately so critical services remain available and secure.
How do you ensure APIs remain reliable under heavy load?+
We test APIs under real-world banking loads including trading spikes, payroll runs, and UPI surges. Performance testing validates that systems remain reliable and responsive when transaction volumes peak, ensuring customers experience no disruption during high-traffic periods.
How do you keep the system safe from attackers inside the organization?+
We validate access controls, role-based permissions, and authentication mechanisms. The system ensures proper authorization, detects privilege escalation attempts, validates token expiry and revocation, and prevents insider threats from accessing unauthorized data or functions.
How do you stay compliant with U.S. and global regulations?+
We automatically detect sensitive data like PII, account numbers, and card data, then generate compliance-ready reports for PCI DSS, GDPR, RBI, and other financial regulations. Continuous monitoring ensures APIs meet regulatory requirements and maintain audit-ready documentation.
