Meeting PCI DSS requirements requires more than periodic vulnerability scans. Organizations handling payment card data need continuous visibility into the security of their web applications and APIs, along with clear evidence that vulnerabilities are identified, prioritized, remediated, and retested.

Acunetix is a dynamic application security testing (DAST) solution that helps organizations strengthen their PCI DSS vulnerability management program by continuously testing running web applications and APIs for exploitable security weaknesses. With authenticated scanning, proof-based scanning, automated scheduling, and detailed reporting, Acunetix helps security teams reduce risk while supporting PCI DSS security testing requirements.

What is a PCI compliance scanner?

A PCI compliance scanner is a security tool used to identify vulnerabilities in systems that fall within the scope of the Payment Card Industry Data Security Standard (PCI DSS). Depending on the use case, this may include infrastructure vulnerability scanners, PCI Approved Scanning Vendor (ASV) services, or application security testing tools.

For organizations developing or operating payment applications, application-layer testing plays a critical role. Public-facing web applications and APIs frequently process, transmit, or influence cardholder data, making them attractive targets for attackers and an important part of PCI DSS vulnerability management.

Acunetix focuses on discovering exploitable vulnerabilities in running web applications and APIs. It complements broader PCI compliance activities by helping organizations continuously assess the security of their application layer.

How Acunetix supports PCI DSS requirements

PCI DSS is a comprehensive security standard covering network security, access control, encryption, monitoring, governance, and vulnerability management. No single product can make an organization PCI compliant.

Acunetix supports the application security and vulnerability management aspects of PCI DSS by helping organizations:

• Continuously scan web applications and APIs for security vulnerabilities
• Test authenticated areas of applications
• Identify exploitable vulnerabilities before attackers do
• Produce detailed reports to support remediation and audit preparation
• Integrate security testing into development and deployment workflows

By embedding automated application security testing into everyday operations, organizations can improve both their security posture and their readiness for PCI assessments.

How DAST helps meet PCI DSS application security requirements

PCI DSS places significant emphasis on developing and maintaining secure applications.

Dynamic application security testing evaluates applications from the outside in, testing deployed applications under real operating conditions. Rather than analyzing source code, DAST interacts with running applications in the same way an attacker would, helping identify vulnerabilities that are actually exposed in production or staging environments.

For organizations processing payment data, this provides several key advantages.

Find vulnerabilities in running applications

Acunetix scans live web applications to identify vulnerabilities including:

• SQL injection
• Cross-site scripting (XSS)
• Server-side request forgery (SSRF)
• Command injection
• Authentication weaknesses
• Security misconfigurations
• Many other web application vulnerabilities

Testing deployed applications provides visibility into the real attack surface exposed to users and attackers.

Test authenticated functionality

Most payment workflows exist behind login pages. Acunetix supports authenticated scanning, allowing security teams to test customer portals, administrative interfaces, checkout processes, and other restricted functionality that unauthenticated scanners cannot reach.

Secure APIs alongside web applications

Modern payment platforms rely heavily on APIs. Acunetix tests REST APIs and other API types alongside traditional web applications to help organizations discover vulnerabilities throughout their application ecosystem instead of focusing solely on the user interface and make API security a routine part of AppSec.

Reduce time spent investigating false positives

Investigating inaccurate findings consumes valuable security and development resources.

Acunetix uses proof-based scanning to automatically verify many vulnerabilities by safely demonstrating exploitability and providing a proof of exploit. Confirmed findings provide developers with clear evidence of the issue, allowing remediation efforts to focus on vulnerabilities that represent real risk and minimize time wasted on false positives.

PCI DSS requirements supported by Acunetix

Acunetix is designed to support the application security activities required as part of a PCI DSS vulnerability management program.

Requirement 6: Develop and maintain secure systems and software

Requirement 6 focuses on identifying and addressing vulnerabilities in software while protecting public-facing web applications against attacks.

Acunetix helps organizations by:

• Continuously testing deployed applications
• Identifying exploitable vulnerabilities
• Supporting secure development workflows
• Providing evidence of testing and remediation activities

Requirement 11: Regularly test security systems and processes

PCI DSS also requires organizations to regularly validate the effectiveness of security controls through testing.

Acunetix supports this objective by enabling scheduled and repeatable application security testing throughout the software lifecycle, helping teams detect newly introduced vulnerabilities after code changes and before production deployments.

While Acunetix supports these requirements, organizations must also implement the broader administrative, operational, and technical controls required by PCI DSS.

What to look for in a PCI compliance scanner

Not all vulnerability scanners provide the same level of coverage or confidence. When evaluating a PCI DSS scanning solution, consider the following capabilities.

Comprehensive application coverage

Modern payment environments often include:

• Customer-facing web applications
• Administrative portals
• Mobile backends
• REST APIs
• Microservices

A scanner should be able to assess the entire application attack surface rather than only publicly visible pages.

Accurate vulnerability detection

Large numbers of false positives slow remediation and increase audit preparation effort. Look for technology that validates findings and produces actionable reports developers can trust.

Authenticated scanning

Payment functionality is frequently protected by authentication. A scanner should be capable of testing authenticated workflows to uncover vulnerabilities that exist behind login screens.

API security testing

Applications increasingly rely on APIs to process transactions and exchange sensitive information. A modern PCI vulnerability scanner should include API security testing alongside traditional web application scanning.

Automation

Application security should become part of normal development operations. Look for capabilities such as:

• Scheduled scans
• Incremental testing
• CI/CD integration
• Automated reporting
• Vulnerability tracking

These features help organizations maintain continuous visibility instead of relying solely on periodic assessments.

Continuous testing improves security and audit readiness

Many organizations still prepare for PCI assessments by performing large-scale security reviews shortly before an audit.

Continuous application security testing provides a more effective approach. By testing applications throughout development and after significant changes, organizations can:

• Discover vulnerabilities earlier
• Reduce remediation costs
• Maintain evidence of ongoing testing
• Improve visibility across application portfolios
• Reduce last-minute audit preparation

Continuous testing does not replace formal PCI validation, but it helps demonstrate that vulnerability management is operating as an ongoing process rather than a once-a-year activity.
