Web Application Pentesting
— PCI-DSS Technical Validation
Proof-driven Web Application Pentesting for organizations in PCI-DSS Technical Validation. We deliver validated exploit evidence, not automated scanner noise.
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 Web Application Pentesting:
Encryption and Key Management (Req. 3-4)
Validating cardholder data encryption at rest and in transit, key rotation, and retention limits.
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.
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.
Access Logging and Traceability (Req. 10)
Ensuring every API call and administrative action touching cardholder data is captured in tamper-evident logs.
Expected Evidence Examples
- Segmentation test report
- ASV scan results and closure evidence
- Access-log integrity validation

Frequently Asked Questions
How long does the Web Application Pentesting process take?
Typically 1-4 weeks depending on scope and infrastructure complexity. We provide a firm timeline after discovery.
What do the deliverables look like?
Each finding includes exploit proof (PoC), business impact score, and developer-friendly remediation code — plus an executive summary.
Can the report support internal review or audit preparation?
Yes. Our reports are prepared as technical evidence packages and remediation records that can support internal review and audit-readiness workflows.
