How to Become PCI DSS Compliant
PCI DSS compliance is required for any business that accepts, processes or transmits card payments. The level of effort involved depends on how your business handles cardholder data.
For many businesses, compliance becomes complex when card data is stored, processed internally or handled manually — particularly for phone and remote payments.
Step 1: Assess Your Current Payment Setup
Start by understanding how your business currently handles payments.
Ask:
- Do you store card data?
- Do staff take card details over the phone?
- Are payments processed through third-party systems?
This determines your PCI scope and which requirements apply to you.
Step 2: Identify Your PCI Compliance Level
Your PCI level is based on transaction volume and determines how compliance is validated.
Most small and medium businesses fall into Level 4, which typically involves completing a Self-Assessment Questionnaire (SAQ) and maintaining basic security controls.
Step 3: Complete the Relevant SAQ
The Self-Assessment Questionnaire (SAQ) is your formal declaration of compliance.
The type of SAQ depends on your setup:
- SAQ A: Fully outsourced payments (lowest burden)
- SAQ A-EP: Ecommerce with partial involvement
- SAQ D: Full card data handling (highest burden)
Choosing the right SAQ is critical, as it defines your compliance requirements.
Step 4: Secure Your Systems and Network
To meet PCI DSS requirements, your systems must be properly secured.
This includes:
- firewalls and network protection
- strong password policies
- regular software updates and patching
- encryption of data in transit
If your systems handle card data directly, the complexity and cost of this step increases significantly.
Step 5: Protect Cardholder Data
PCI DSS requires strict controls around cardholder data.
This means:
- restricting access to authorised users only
- encrypting sensitive information
- avoiding unnecessary storage of card data
The more card data your business handles, the greater the compliance burden.
Step 6: Run Security Scans and Testing
Depending on your setup, you may need to:
- complete quarterly vulnerability scans
- test your systems for weaknesses
- maintain logs and monitoring systems
These checks ensure your systems remain secure over time.
Step 7: Submit Compliance Documentation
Once complete, you must submit:
- your SAQ
- any required scan results
- an Attestation of Compliance
This is usually provided to your acquiring bank or payment provider.
Step 8: Maintain Ongoing Compliance
PCI compliance is not a one-off task.
You must:
- review your systems regularly
- update security measures
- stay aligned with PCI DSS updates
- maintain documentation annually
The Smarter Way to Achieve PCI Compliance
For many businesses, the most effective way to simplify PCI compliance is to reduce or remove cardholder data from their environment entirely.
This can be achieved by:
- using hosted payment pages
- using pay by link solutions
- ensuring customers enter their own payment details
By doing this, businesses can often qualify for simpler SAQs and significantly reduce compliance effort.
Common Challenges Businesses Face
Many organisations struggle with PCI compliance due to:
- handling card details manually (especially over the phone)
- storing sensitive data unnecessarily
- relying on outdated systems
- misunderstanding their SAQ requirements
Addressing these issues early can prevent costly mistakes later.
