PCI DSS Scan Requirements

External and internal vulnerability scanning to support your PCI DSS scanning obligations — with remediation guidance and rescans to reach a clean, compliant result.

Overview

Keep your PCI DSS scans clean, quarter after quarter.

PCI DSS requires regular internal and external vulnerability scanning, and passing those scans is a recurring obligation rather than a one-off. Failed scans stall compliance and create audit findings.

We run the scans, interpret the results, and help you remediate and rescan until you reach a passing position — then keep you on a quarterly cadence so compliance stays continuous rather than a last-minute scramble.

What we test

Focus areas of the assessment.

The core areas we examine in a pci dss scan requirements engagement.

External vulnerability scanning

Internet-facing scanning of in-scope systems against PCI requirements.

Internal vulnerability scanning

Scanning inside the cardholder data environment for internal exposures.

Quarterly scan cadence

A managed schedule that keeps you continuously aligned to PCI timelines.

Remediation & rescan support

Help interpreting results, fixing issues and rescanning to a clean pass.

Attestation of compliance

Documentation of passing scans to evidence your PCI obligations.

Regulatory drivers

Why this is required

External vulnerability scanning by an Approved Scanning Vendor is a named, recurring PCI DSS requirement, and passing scans are evidence you must retain and submit to your acquirer.

PCI DSS v4.0 (Req 11.3.2)
Requires external vulnerability scans by a PCI ASV at least quarterly and after significant change, with a passing result.
Acquirer & card-brand programmes
Acquiring banks and card brands require ASV scan evidence as part of ongoing PCI validation.
Remediation & rescan
Failed scans must be remediated and rescanned until a passing result is achieved and documented.
How we work

A disciplined testing methodology.

A repeatable, standards-based process that balances depth with operational safety.

Scoping & asset confirmation

Confirming the external-facing assets in the cardholder data environment.

ASV scan configuration

Configuring the approved-scanning-vendor scan to PCI requirements.

Vulnerability scanning

Running the scan and identifying vulnerabilities against PCI thresholds.

False-positive review

Reviewing and validating results, with dispute handling where needed.

Remediation & rescan

Supporting remediation and rescanning until a passing result is reached.

Attestation of compliance

Issuing the passing scan report for your PCI DSS evidence.

FAQ

Common questions

How often are PCI scans required?
PCI DSS requires internal and external vulnerability scans at least quarterly and after any significant change. We manage that cadence so nothing is missed.
What happens if a scan fails?
We help you understand the findings, remediate the issues and rescan until you reach a passing result — failed scans must be resolved and re-run to demonstrate compliance.
Does this replace a penetration test?
No. PCI DSS requires both vulnerability scanning and separate penetration testing; the two are complementary. We provide both under one roof.
