The Basics

What Is an ASV Scan?

An ASV scan is a quarterly security assessment performed by an Approved Scanning Vendor (ASV). Think of it as a security check-up for your business’s internet-facing systems that handle credit card data.

The scan works like a security guard checking all the doors and windows of your digital storefront. It looks for vulnerabilities – essentially weak spots that hackers could exploit to steal credit card information.

Key Terminology Explained

ASV (Approved Scanning Vendor): A company authorized by the PCI Security Standards Council to perform these specialized security scans. Not just anyone can do these scans – they must be officially approved.

Vulnerability: A security weakness in your systems, like an outdated software version or misconfigured setting that could be exploited by cybercriminals.

PCI DSS: The Payment Card Industry Data Security Standard – the set of security requirements all businesses accepting credit cards must follow.

Quarterly Scanning: ASV scans must be performed every three months (four times per year) to maintain compliance.

How ASV Scans Relate to Your Business

If your business has any internet-facing systems that store, process, or transmit credit card data, you likely need ASV scans. This includes:

E-commerce websites
Point-of-sale systems connected to the internet
Payment processing applications
Any servers or databases handling card data

The scan examines these systems from the outside (like a hacker would) to identify potential security risks before they become real problems.

Why It Matters

Business Implications

ASV scans aren’t optional for most businesses accepting credit cards. They’re a mandatory requirement under PCI DSS for companies that:

Process more than 20,000 e-commerce transactions annually
Store cardholder data
Have internet-facing payment systems

Even if you’re not required to perform ASV scans, they’re still valuable for identifying security weaknesses before criminals do.

Risk of Non-Compliance

Failing to complete required ASV scans can result in:

Fines from payment processors: Monthly penalties ranging from $5,000 to $100,000
Increased transaction fees: Payment processors may impose higher rates
Loss of card acceptance privileges: Your ability to process credit cards could be suspended
Liability for breaches: Without compliance, you may be responsible for all costs related to How toes

Benefits of Compliance

Regular ASV scanning provides numerous advantages:

Early threat detection: Find vulnerabilities before hackers do
Reduced breach risk: Address security gaps proactively
Compliance assurance: Meet PCI DSS requirements confidently
Customer trust: Demonstrate your commitment to protecting their data
Business continuity: Avoid disruptions from compliance issues

Step-by-Step Guide

Step 1: Determine If You Need ASV Scans

First, identify whether ASV scanning applies to your business:

Do you have any internet-facing systems that handle credit card data?
Are you required to complete SAQ A-EP, SAQ B, SAQ C, or SAQ D?
Do you process more than 20,000 e-commerce transactions annually?

If you answered yes to any of these questions, you likely need quarterly ASV scans.

Step 2: Choose an Approved Scanning Vendor

Select an ASV from the official list maintained by the PCI Security Standards Council. Consider factors like:

Pricing: Costs typically range from $100-500+ per quarter
Support quality: Look for responsive customer service
Reporting capabilities: Ensure clear, actionable reports
Integration options: Some ASVs integrate with compliance management tools

Step 3: Prepare Your Systems

Before your first scan:

Document your systems: Create a list of all internet-facing systems that handle card data
Gather IP addresses: You’ll need to provide these to your ASV
Review firewall settings: Ensure proper configurations are in place
Update software: Install the latest security patches

Step 4: Schedule Your First Scan

Most ASVs offer:

On-demand scanning: Run scans whenever you need them
Automated scheduling: Set up quarterly scans in advance
Pre-scan consultation: Some vendors help you prepare

Step 5: Review and Address Results

When you receive your scan report:

Review all findings: Understand each identified vulnerability
Prioritize remediation: Address critical issues first
Implement fixes: Work with your IT team or vendor to resolve problems
Request rescans: Get confirmation that issues are resolved

Timeline Expectations

Initial setup: 1-2 weeks to select vendor and configure scanning
Scan duration: Most scans complete within 24-48 hours
Remediation time: Varies based on findings, typically 1-4 weeks
Ongoing schedule: Quarterly scans throughout the year

Common Questions Beginners Have

“Are ASV scans the same as penetration testing?”

No, they’re different. ASV scans are automated vulnerability assessments that look for known security issues. Penetration testing involves human experts actively trying to exploit vulnerabilities. ASV scans are less expensive and required for PCI compliance, while penetration testing is more thorough but typically only required for larger businesses.

“Will the scan disrupt my business operations?”

ASV scans are designed to be non-intrusive. They examine your systems from the outside without affecting normal operations. However, it’s good practice to schedule scans during off-peak hours as a precaution.

“What happens if my scan fails?”

Don’t panic – failed scans are common, especially for first-time scanning. Your ASV will provide a detailed report explaining what needs to be fixed. You’ll have time to address the issues and request a rescan. Most vendors offer unlimited rescans until you achieve a passing result.

“How often do I really need to scan?”

PCI DSS requires quarterly scanning (every three months). However, you should also scan after any significant changes to your systems, such as software updates, configuration changes, or new installations.

“Can I perform ASV scans myself?”

No, ASV scans must be performed by an officially approved scanning vendor. However, you can run your own internal vulnerability scans using various tools – these just won’t satisfy PCI compliance requirements.

Mistakes to Avoid

Waiting Until the Last Minute

The mistake: Many businesses wait until just before their compliance deadline to start ASV scanning.

Why it’s problematic: If your scan fails, you may not have enough time to fix issues and rescan before your deadline.

How to prevent it: Start your ASV scanning process at least 6-8 weeks before your compliance deadline.

Not Understanding Your Scope

The mistake: Failing to identify all systems that need to be scanned.

Why it’s problematic: Missing systems in your scan scope can leave vulnerabilities undetected and may not satisfy compliance requirements.

How to prevent it: Work with a qualified professional to map your cardholder data environment and identify all internet-facing systems.

Ignoring “Informational” Findings

The mistake: Only addressing critical vulnerabilities while ignoring lower-priority findings.

Why it’s problematic: Multiple minor vulnerabilities can sometimes be chained together for a successful attack.

How to prevent it: Review all scan findings and address them based on your risk tolerance and available resources.

Choosing the Cheapest Option

The mistake: Selecting an ASV based solely on price.

Why it’s problematic: Poor support quality can lead to delays, confusion, and compliance issues.

How to prevent it: Evaluate ASVs based on overall value, including support quality, reporting capabilities, and customer reviews.

What to Do If You Make These Mistakes

If you’ve already made one of these mistakes:
1. Acknowledge the issue promptly
2. Assess the impact on your compliance timeline
3. Develop a corrective action plan
4. Communicate with stakeholders about any delays
5. Implement processes to prevent future occurrences

FAQ

Q: How much do ASV scans typically cost?

A: ASV scan costs typically range from $100-500 per quarter, depending on the number of IP addresses scanned, the complexity of your environment, and the level of support included. Some vendors offer annual pricing discounts.

Q: What’s the difference between internal and external vulnerability scanning?

A: External scanning (ASV scans) examines your systems from the internet, looking for vulnerabilities that outside attackers could exploit. Internal scanning examines your network from the inside. Both may be required depending on your PCI compliance level.

Q: Can I change ASV providers if I’m not satisfied?

A: Yes, you can switch ASV providers at any time. However, ensure your new provider can meet your compliance deadlines and that you maintain your quarterly scanning schedule during the transition.

Q: What happens if I can’t fix a vulnerability before my compliance deadline?

A: Contact your acquiring bank or payment processor immediately to discuss your situation. They may provide a grace period for remediation, but continuing to process cards with known vulnerabilities puts you at significant risk.

Q: Do I need ASV scans if I use a payment service provider like PayPal or Square?

A: It depends on your specific setup and which SAQ you’re required to complete. If you redirect customers to a third-party payment page and don’t store any card data, you may not need ASV scans. However, if you have any internet-facing systems that handle card data, scanning is likely required.

Q: How long are ASV scan reports valid for compliance purposes?

A: ASV scan reports are generally valid for one year from the scan date for annual compliance validation. However, you must continue performing quarterly scans throughout the year to maintain ongoing compliance.

Conclusion

ASV scanning is a critical component of PCI compliance that protects your business and customers from security threats. While the process might seem complex at first, understanding the basics helps you make informed decisions about your compliance strategy.

Remember that ASV scanning is not just about meeting requirements – it’s about protecting your business from the devastating costs of data breaches and maintaining customer trust in an increasingly digital world.

The key to successful ASV scanning is starting early, choosing the right vendor, and treating it as an ongoing process rather than a one-time event. With proper planning and execution, ASV scanning becomes a manageable part of your security routine.
