API Security Testing
— PCI-DSS Technical Validation
Go beyond standard compliance checks. Get world-class API Security Testing tailored for PCI-DSS Technical Validation and view your infrastructure through real hackers' eyes.
Free Scoping CallPCI-DSS Technical Validation Control and Evidence Readiness
Technical validation of PCI DSS v4.0 requirements for systems that store, process, or transmit cardholder data.
The PCI-DSS Technical Validation control areas most relevant to API Security Testing:
Access Logging and Traceability (Req. 10)
Ensuring every API call and administrative action touching cardholder data is captured in tamper-evident logs.
Cardholder Data Environment (CDE) Segmentation
Verifying the CDE is genuinely isolated from the rest of the network through active segmentation testing.
Firewall and Network Configuration (Req. 1)
Auditing firewall rule sets, unnecessary open ports, and default configurations.
Encryption and Key Management (Req. 3-4)
Validating cardholder data encryption at rest and in transit, key rotation, and retention limits.
Regular Vulnerability Scanning and Penetration Testing (Req. 11)
Meeting the quarterly ASV scan and annual penetration test requirement with real exploit evidence, not scanner output alone.
Expected Evidence Examples
- Segmentation test report
- ASV scan results and closure evidence
- Access-log integrity validation

Frequently Asked Questions
What is the timeline for a API Security Testing project?
Depending on the size of the application or network, it takes 5 to 20 business days on average.
What do we receive at the end of the test?
PoC evidence showing exactly how vulnerabilities are exploited, remediation code, and an executive summary for C-Level management.
How do you ensure data security during the test?
All tests are performed under a strict NDA with the principle of least privilege, and all logs are securely wiped post-engagement.
