PCI-DSS Audit and Penetration Testing Services

PCI-DSS Services from Ascend

The Payment Card Industry Data Security Standard (PCI DSS) is a global security standard maintained by the PCI Security Standards Council on behalf of the major card brands, including Visa, Mastercard, American Express, Discover, and JCB. It applies to any organization that stores, processes, or transmits cardholder data, as well as organizations that can affect the security of that data. The current version of the standard is PCI DSS 4.0.1.

The 12 PCI DSS Requirements

PCI DSS is organized into six goals that contain twelve core requirements:

Goal	Requirements
Secure Networks	1. Install and maintain network security controls. 2. Apply secure configurations to all system components.
Protect Account Data	3. Protect stored account data. 4. Protect cardholder data with strong cryptography during transmission over open, public networks.
Manage Vulnerabilities	5. Protect all systems and networks from malicious software. 6. Develop and maintain secure systems and software.
Control Access	7. Restrict access to cardholder data by business need to know. 8. Identify users and authenticate access to system components. 9. Restrict physical access to cardholder data.
Monitor and Test	10. Log and monitor all access to system components and cardholder data. 11. Test the security of systems and networks regularly.
Security Policy	12. Support information security with organizational policies and programs.

How is Compliance Validated?

Validation depends on your merchant or service provider level, which is determined by annual transaction volume. Smaller organizations typically complete a Self-Assessment Questionnaire (SAQ), while larger organizations undergo a formal assessment resulting in a Report on Compliance (ROC). In addition, most organizations must complete quarterly external vulnerability scans and periodic penetration testing to demonstrate that their controls are working.

How Ascend Security & Assessment Can Help

Ascend supports organizations at every stage of their PCI DSS journey, from first-time scoping through annual revalidation. Our team helps you understand exactly which requirements apply to your environment and builds a practical path to compliance.

Readiness and Gap Assessments

We begin by defining your cardholder data environment and identifying where card data lives across your systems, networks, and third parties. From there, we assess your current controls against the applicable PCI DSS requirements, document any gaps, and provide a prioritized remediation roadmap. Proper scoping alone often reduces the cost and effort of compliance significantly.

Penetration Testing Services

Requirement 11 calls for internal and external penetration testing at least annually and after any significant change to your environment. Our penetration testing services cover network-layer and application-layer testing, along with segmentation testing to confirm that your cardholder data environment is properly isolated from the rest of your network. You receive a clear report with findings ranked by risk, evidence for your assessor, and retesting to verify that issues have been resolved.

ASV Scanning Services

PCI DSS requires quarterly external vulnerability scans performed by an Approved Scanning Vendor (ASV). Ascend manages this process end to end: scheduling scans, reviewing results, helping your team remediate failing items, and rescanning until you achieve a passing result. We also handle the attestation documentation needed for your acquiring bank or customers.

Ongoing Compliance Support

PCI DSS is not a once-a-year exercise. We help you select and complete the correct SAQ, gather evidence throughout the year, maintain required policies and training, and prepare for formal assessments so that revalidation becomes routine rather than a scramble.
