Running a business that accepts, processes, or stores credit card data? Then, you have surely heard about PCI compliance. However, hearing “PCI ASV Scan” can make things confusing.
In layman’s terms, a PCI ASV scan is not just another tech requirement. It is a formal, mandatory check on your internet-facing systems to ensure they’re not exposing sensitive payment data to cyber risks. For many Vietnamese startups, eCommerce businesses, or software companies working with global payment platforms, the right PCI ASV scan vendor can help you in becoming PCI DSS compliant.
In this blog, we delve deeper into PCI ASV scans and understand what it does, the process, and how Qualysec, the leading PCI ASV scan vendor, can help companies with this scan.
PCI ASV Scan: What Is It?
Wondering what is PCI ASV scan is?
A PCI ASV scan is a security scan performed by an Approved Scanning Vendor (ASV) to identify vulnerabilities in your publicly accessible systems. These include web servers, firewalls, or payment gateways. It’s a required component under Requirement 11.3.2 of the PCI DSS (Payment Card Industry Data Security Standard).
It is important to understand that the PCI DSS ASV scan is not an internal audit or a general antivirus check. This is a targeted external scan to detect if any known vulnerabilities are present on your systems that could be exploited by attackers.
For global businesses working with international platforms, this scan might be a contractual requirement. However, keep in mind that ASV scans are only one part of the broader PCI DSS requirements. Here is where businesses begin their compliance journey.
Types of PCI ASV Scans
There are different types of PCI ASV scans, and none of them are created equal. The technical standard for the scan is indeed defined by the PCI Security Standards Council. However, the delivery model and support differ according to the PCI ASV scan vendor you choose.
1. Self-Service Scanning Platforms
These are cloud-based tools where you sign up, enter your IPs or domains, initiate the scan, and get a report.
Pros:
- Budget-friendly
- Fast onboarding
- Automated reports submitted directly to the PCI SSC
Cons:
- No manual review of results
- No help interpreting scan findings
- No remediation guidance or re-test planning
- High chance of false positives, especially for custom-built apps
2. Managed PCI ASV Scanning Services
This model combines automated scanning with expert oversight. As a leading PCI ASV scan vendor, Qualysec falls in this category.
Pros:
- Manual validation minimizes false positives
- Clear scoping ensures compliance and accuracy
- Guidance on remediation steps
- Often includes retesting support
- Human communication
Cons:
- Typically higher in price, depending on the scope
- May require a short onboarding window for team sync
3. Enterprise PCI Compliance Suites
This category includes full PCI DSS software platforms that bundle ASV scans into broader compliance tools.
Pros:
- Great for enterprises with in-house security teams
- Integrates with other compliance workflows
- Audit trail features, report storage, and ongoing monitoring
Cons:
- Expensive, often enterprise-tier only
- Steep learning curve for smaller teams
- Requires more in-house effort to manage scans and remediations
What Do You Need for a PCI ASV Scan?
Before a PCI ASV scan begins, there are some things that need to be readied. It is not as easy as simply submitting a website URL.
The most important thing is defining the scan scope. This means identifying which of your systems are exposed to the internet. It may include public-facing IP addresses, websites, APIs, or cloud-hosted assets.
Next, it is critical to understand your business classification under PCI DSS. Whether you are a merchant, a payment service provider, or a third-party vendor will affect how your scan is scoped and reported.
After that, knowing more about the scan window is important. If your systems are sensitive to traffic or uptime issues, you may want to coordinate the scan during off-peak hours or maintenance periods.
Why PCI ASV Scans Matter?
Understand this – A PCI DSS ASV scanning isn’t just a regulatory hurdle, it’s your digital risk detector. That’s why you need to choose the best PCI ASV scan providers.
Many breaches don’t start with zero-day exploits or elite hackers. They start with simple oversights. Here, the ASV scan identifies these risks before attackers do.
While Vietnam’s digital economy is on the rise, its cybersecurity maturity remains uneven. That is why even though Vietnam’s legal framework doesn’t enforce PCI DSS, your processors and overseas clients will.
The Benefits of Passing a PCI ASV Scan:
- Builds trust with customers and partners
- Satisfies one major step in PCI DSS compliance
- Prevents small security holes from becoming massive liabilities
- Improves your reputation with global clients or investors
- Prepares your system for other audits like SOC 2, ISO 27001, etc.
The PCI ASV Scan Process (Step-by-Step Guide)
If you have never done a ASV scan report before, take a good look at these steps. It will help you understand the entire process easily and pick the best PCI ASV scan providers–
Step 1: Scope Confirmation
Before the process of scanning begins, the ASV will ask for some confirmations. This includes systems in scope, what IPs or domains will be tested, the business type, and the SAQ classification.
Step 2: Initial Scan Execution
The vendor runs an external automated vulnerability scan against the defined assets. This simulates what an attacker might discover from the public internet—no login or internal access is required.
The scan typically takes anywhere from a few hours to 24 hours, depending on system complexity and configuration.
Step 3: Results Review
This part is different for different service providers. Some self-service platforms simply auto-issue a report. On the other hand, reputed experts like Qualysec manually review scan results before anything is finalized. This filters out false positives and ensures the report reflects your real security state.
Step 4: Fixing the Issues
If any medium or high-severity vulnerabilities are found, the scan result fails. Now, you need to patch the affected systems, update the software version, and reconfigure the misaligned services.
Step 5: Retesting & Final Report Submission
After the fixes are done, the ASV re-runs the scan to verify that the issues were fixed. Once everything is clean, the final compliance-ready scan report is submitted to the PCI Security Standards Council (PCI SSC).
ASV Scans and PCI Compliance
The PCI ASV scan is one of the most popular PCI DSS processes. To clarify this even more, let’s take a look at this.
The ASV scan covers:
- Requirement 11.3.2 under PCI DSS v4.0
- External vulnerability scanning
- Quarterly or post-change testing
- Public-facing systems only
