The Basics: Understanding PCI DSS and Klarna

What is PCI DSS?

PCI DSS (Payment Card Industry Data Security Standard) is a set of security requirements designed to protect credit card information. Think of it as a comprehensive security checklist that any business handling, storing, or transmitting credit card data must follow.

The standard was created by major credit card companies (Visa, MasterCard, American Express, Discover, and JCB) to reduce credit card fraud and data breaches.

Key PCI Terminology You Should Know

Merchant: Any business that accepts credit card payments (that’s likely you)
SAQ (Self-Assessment Questionnaire): A validation tool for merchants to assess their compliance with PCI DSS
Cardholder Data Environment (CDE): Systems, networks, and processes that store, process, or transmit cardholder data
Service Provider: Companies like Klarna that provide payment processing services

How Klarna Fits Into PCI Compliance

Klarna is a payment service provider that offers various payment solutions, including:

Buy now, pay later options
Instant financing

When you use Klarna, you’re essentially partnering with them to process payments. However, this doesn’t automatically eliminate all your PCI compliance responsibilities—it just changes what you need to focus on.

Understanding Your Role vs. Klarna’s Role

Klarna’s Responsibilities:

Maintaining PCI compliance for their payment processing infrastructure
Securing the payment data they handle
Providing secure payment interfaces
Managing the technical aspects of payment processing

Your Responsibilities:

Ensuring your website and systems that interact with Klarna are secure
Properly implementing Klarna’s solutions

Operational Impact: Compliance helps streamline your security processes and can actually make your business operations more efficient by establishing clear security protocols.

Competitive Advantage: Being PCI compliant demonstrates to customers that you take their security seriously, which can be a significant competitive advantage in today’s security-conscious marketplace.

Step-by-Step Guide to Klarna PCI Compliance

Step 1: Determine Your Compliance Requirements

First, you need to understand which PCI DSS requirements apply to your specific Klarna implementation.

Assessment Questions:

How is Klarna integrated into your website?
Do you handle credit card information directly?
Does credit card data pass through your servers?
Do you store any payment information?

Most Common Scenarios:

Klarna Checkout Only: If you only use Klarna’s hosted checkout, your requirements are typically minimal
Klarna + Other Payment Methods: If you accept other payment methods alongside Klarna, you need broader compliance
Custom Integration: If you have custom API integrations, you may have additional requirements

Step 2: Identify Your SAQ Type

Based on your assessment, you’ll need to complete a specific Self-Assessment Questionnaire:

SAQ A: For merchants using only hosted payment solutions (most basic Klarna implementations)
SAQ A-EP: For e-commerce merchants with website-based payment processing
SAQ B: For merchants using imprint machines or standalone terminals
SAQ C: For merchants with payment applications connected to the internet
SAQ D: For all other merchants and service providers

Step 3: Implement Required Security Measures

Regardless of your SAQ type, you’ll need to address certain fundamental security requirements:

Network Security:

Install and maintain firewalls
Remove default passwords from all systems
Encrypt data transmissions over public networks

Access Control:

Restrict access to cardholder data on a need-to-know basis
Assign unique user IDs to each person with computer access
Implement two-factor authentication where feasible

Monitoring:

Install anti-virus software and keep it updated
Develop and maintain secure systems and applications
Implement logging and monitoring systems

Step 4: Complete Your SAQ

Once you’ve implemented the necessary controls:

1. Download the appropriate SAQ from the PCI Security Standards Council website
2. Answer each question honestly based on your current security posture
3. Provide evidence for your answers where required
4. Have a qualified person review your responses

Step 5: Submit Compliance Documentation

Submit your completed SAQ and any required documentation to:

Your payment processor
Your acquiring bank
Any other parties specified in your merchant agreement

Timeline Expectations

Initial Assessment: 1-2 weeks
Implementation: 4-12 weeks (depending on current security posture)
SAQ Completion: 1-2 weeks
Annual Renewal: Ongoing requirement

Common Questions Beginners Have

“Do I Really Need to Be PCI Compliant If I Use Klarna?”

Yes, you still need to be PCI compliant, but your requirements may be simplified. Klarna handles much of the heavy lifting, but you’re still responsible for certain aspects of security, particularly related to your website and how you implement Klarna’s services.

“What If I Only Use Klarna’s Hosted Checkout?”

If you exclusively use Klarna’s hosted checkout solution and don’t handle credit card data directly, you’ll likely qualify for SAQ A, which is the simplest compliance path. However, you still need to complete the assessment and maintain basic security measures.

“How Often Do I Need to Validate Compliance?”

PCI compliance validation is required annually. However, you need to maintain compliance year-round—the annual validation is just formal confirmation that you’re meeting the requirements.

“What About PCI Scanning Requirements?”

If your SAQ requires it, you’ll need quarterly vulnerability scans performed by an Approved Scanning Vendor (ASV). Many Klarna-only implementations may not require external scanning, but this depends on your specific setup.

“Can I Handle My Own PCI Compliance?”

Many businesses can handle their own PCI compliance, especially if they’re using Klarna’s hosted solutions. However, larger businesses or those with complex setups may benefit from professional assistance.

Mistakes to Avoid

Common Beginner Errors

Assuming Klarna Handles Everything: While Klarna manages payment processing security, you’re still responsible for your website security, proper implementation, and overall compliance with applicable PCI requirements.

Ignoring Annual Requirements: PCI compliance isn’t a one-time activity. You need to validate compliance annually and maintain security measures year-round.

Choosing the Wrong SAQ: Using an incorrect SAQ can lead to incomplete compliance. Take time to properly assess your environment before selecting your questionnaire type.

Not Documenting Everything: PCI compliance requires documentation. Keep records of your policies, procedures, and evidence of compliance activities.

Overlooking Website Security: Even with Klarna handling payments, your website still needs basic security measures like SSL certificates, regular updates, and secure hosting.

How to Prevent These Mistakes

1. Get Educated: Take time to understand PCI requirements that apply to your business
2. Start Early: Don’t wait until the last minute to address compliance
3. Keep Records: Document all your compliance activities and maintain evidence
4. Regular Reviews: Periodically review your setup to ensure ongoing compliance
5. Stay Updated: Keep up with changes in PCI requirements and Klarna’s services

What to Do If You Make Mistakes

If you discover compliance gaps:

1. Don’t Panic: Most issues can be resolved with proper action
2. Assess the Impact: Determine what data might be at risk
3. Take Immediate Action: Implement fixes as quickly as possible
4. Document Everything: Record what happened and what you did to fix it
5. Learn from It: Use the experience to improve your ongoing compliance program

Frequently Asked Questions

1. Does using Klarna automatically make me PCI compliant?

No, using Klarna doesn’t automatically make you PCI compliant. While Klarna handles much of the payment processing security, you’re still responsible for certain compliance requirements, including website security, proper implementation of Klarna’s services, and completing the appropriate Self-Assessment Questionnaire (SAQ).

2. Which SAQ do I need to complete when using Klarna?

The SAQ type depends on your specific implementation. Most merchants using only Klarna’s hosted checkout solutions qualify for SAQ A, which is the simplest option. However, if you use other payment methods alongside Klarna or have custom integrations, you may need a different SAQ type like SAQ A-EP or SAQ D.

3. How much does PCI compliance cost for Klarna users?

Costs vary depending on your approach. DIY compliance using PCI and M&A: might cost $100-500 annually, while professional services can range from $1,000-10,000+ per year. However, these costs are typically much lower than the potential fines and damages from non-compliance.

4. What happens if I don’t maintain PCI compliance while using Klarna?

Non-compliance can result in monthly fines ($5,000-$100,000), increased transaction fees, loss of payment processing privileges, and liability for security breaches. Even though Klarna handles payment processing, you’re still contractually obligated to maintain compliance for your part of the payment process.

5. How often do I need to validate my PCI compliance?

PCI compliance validation is required annually, but you must maintain compliance year-round. This means implementing and maintaining security controls continuously, not just during the annual assessment period. Some requirements, like vulnerability scanning, may need to be performed quarterly.

6. Can I store customer payment information if I use Klarna?

Generally, if you’re using Klarna’s payment services, you shouldn’t need to store sensitive payment information like credit card numbers. Klarna is designed to handle this data securely. If you do need to store any payment-related information, you’ll have significantly more complex PCI compliance requirements and should consult with a qualified security professional.
