Web application scanning for PCI DSS 4.0

PCI DSS is the Payment Card Industry Data Security Standard for any organization that stores, processes, or transmits cardholder data. Version 4.0 sets requirements across network security, encryption, access control, vulnerability management, logging, and testing. AuditWard runs a PCI DSS 4.0 web application scan and tags the findings.

Background

Where PCI DSS touches your web app.

PCI DSS 4.0 (with the 4.0.1 revision) is validated through self-assessment questionnaires or a formal Report on Compliance. Two requirements matter most for a public web app. Requirement 6 covers secure development and addressing common web vulnerabilities. Requirement 11.3 covers internal and external vulnerability scanning.

Requirement 11.3.2 is the strict one. It mandates external scans, run at least every three months, by a PCI SSC Approved Scanning Vendor (ASV), with a passing result before the cardholder data environment can be considered compliant. AuditWard works alongside that ASV scan. It finds and evidences web-application issues early, so you walk into the quarterly scan with fewer surprises.

Mapping

How AuditWard supports your PCI DSS 4.0 work.

AuditWard scans your site in one pass, then tags each confirmed finding to the PCI DSS requirement it relates to. The table below lines up the checks AuditWard actually runs against the control areas they bear on. This is a triage aid for your own vulnerability management, not a requirement mapping signed off by a QSA.

Honest limits

What AuditWard does not do.

AuditWard is not a certification and it does not make you PCI compliant. The most important limit comes first: AuditWard is not a PCI SSC Approved Scanning Vendor, so it cannot run or satisfy the Requirement 11.3.2 external ASV scan. Read these limits before you plan around the tool.

Not an ASV, not an AoC

AuditWard is not a PCI SSC Approved Scanning Vendor. It cannot perform or satisfy the Requirement 11.3.2 external ASV scan, and its report is not an ASV scan report or an Attestation of Compliance.

The quarterly ASV scan still applies

A quarterly ASV scan from an approved vendor, plus the broader PCI assessment, is still mandatory and entirely separate from anything AuditWard produces.

Most of PCI is out of scope here

AuditWard does not assess network segmentation, key management, logging, access-control, or policy requirements. Those make up the bulk of PCI DSS and need other controls and evidence.

No pass or fail determination

PCI passing criteria reject any vulnerability at CVSS 4.0 or above. AuditWard scores findings but does not issue pass/fail ASV determinations or handle the formal dispute process.

The tags are an aid, not authority

The PCI tags come from an LLM. Treat them as a starting point for triage, not an authoritative requirement mapping reviewed by a QSA or ASV. Your assessor has the final say on how each finding maps to a requirement.

Next steps

What to do with the evidence.

Use an AuditWard scan to clean up your web app ahead of the formal PCI process, not as a stand-in for it. The dated PDF report, with CVSS scores and remediation steps, slots into your internal vulnerability management. Here is a workable order of operations.

01TRIAGE

Run a scan of your in-scope app and sort the findings by CVSS. Anything at CVSS 4.0 or above is what a PCI ASV scan would flag, so fix those first.

02REMEDIATE

Work through the per-finding remediation guidance: tighten TLS and ciphers, add the missing headers, remove exposed files, and patch outdated components. Re-scan to confirm the fixes.

03EVIDENCE

Attach the dated report to your internal vulnerability management records and your Requirement 6 tracking, then book your separate quarterly ASV scan with an approved vendor.

FAQ

PCI DSS questions.

Is an AuditWard scan a PCI ASV scan?

No. AuditWard is not a PCI SSC Approved Scanning Vendor, so it cannot run or satisfy the Requirement 11.3.2 external ASV scan. Its report is not an ASV scan report or an Attestation of Compliance. You still need a quarterly scan from an approved vendor.

Does AuditWard make my app PCI DSS 4.0 compliant?

No. AuditWard helps you find and evidence web-application issues mapped to PCI requirements. Compliance comes from your controls, your broader assessment, and the required ASV scan. AuditWard supports that work and does not certify you.

How does a PCI DSS 4.0 web application scan help before my ASV scan?

It surfaces TLS weaknesses, missing headers, exposed files, injection indicators, and outdated software early, with CVSS scores and remediation steps. You fix what a PCI ASV scan would flag (anything at CVSS 4.0 or above) so the formal quarterly scan has fewer findings to resolve.

Which PCI requirements does AuditWard touch?

Mostly Requirement 6 (secure web development and common web vulnerabilities) and the vulnerability management side of Requirement 11.3, plus the encryption-in-transit expectations around cardholder data. It does not assess segmentation, key management, logging, access control, or policy requirements.

Are the PCI tags an official requirement mapping?

No. The PCI tags come from an LLM and are a triage aid, not an authoritative mapping reviewed by a QSA or ASV. Your assessor has the final say on how each finding maps to a PCI DSS 4.0 requirement.
