A PCI compliance service provider helps businesses meet the requirements of the Payment Card Industry Data Security Standard (PCI DSS) by taking on some of the compliance work. That can mean processing card data outside a business’s systems, running the audits and scans required by PCI DSS, or advising on which self-assessment applies.

The global average cost of a data breach was $4.4 million in 2025, and reducing how much cardholder data touches a business’s systems can help shrink that exposure.

Below, we’ll discuss what PCI-compliant service providers do, the PCI DSS obligations that apply to them, and the categories they fall into.

Key takeaways

• PCI compliance service providers take on part of a business’s PCI DSS obligations, including processing card data and running required audits and scans.

• Different PCI compliance service providers include payment providers, security-focused compliance vendors, hosted payment field providers, and PCI consultants.

• Tools such as hosted payment fields and tokenization reduce how much of PCI DSS applies to a business by keeping cardholder data out of its systems.

What is a PCI compliance service provider?

A PCI compliance service provider helps businesses meet the requirements of PCI DSS. These providers sit between a business and the card networks that wrote the standard and enforce it.

What are the PCI DSS requirements for service providers?

Service providers face a stricter PCI DSS compliance threshold than a typical business because their systems tend to hold cardholder data at higher volume and for longer. The standard splits providers into two levels based on transaction volume, and that level determines whether a self-assessment is enough or whether an independent audit is required.

Level 1 providers typically are those that handle more than 300,000 transactions a year, though the threshold can vary by card brand. These providers must complete a Report on Compliance (ROC), carried out by a Qualified Security Assessor (QSA). This is a full audit in which the QSA tests controls.

Level 2 providers (typically those at or below 300,000 annual transactions) can usually complete a Self-Assessment Questionnaire (SAQ) instead, although card brands often still require a QSA-led review if the service affects high-risk environments. This typically means completing an SAQ D for service providers, which covers nearly all 300-plus PCI DSS controls. A provider that tokenizes card data or uses a validated point-to-point encryption solution can mark a large share of those controls not applicable, while a provider that stores cardholder data must address nearly all of them.

Beyond the assessment, service providers carry standing obligations: quarterly scans from an Approved Scanning Vendor (ASV), annual penetration testing, and continuous monitoring of file integrity and access logs. They also need a formal incident response plan and network segmentation that keeps systems touching cardholder data separate from everything else. Card networks require providers to appear on an approved list, and a business can confirm that status through Visa or Mastercard.

What types of PCI compliance service providers exist?

The PCI compliance service provider landscape splits into a few distinct categories.

The main options are:

• Payment providers: These process transactions directly and often shrink a business’s PCI scope by handling card data outside the business’s systems. When a business accepts a payment, the card data travels from the customer’s browser to the provider’s servers and never touches the business’s web server.

• Security-focused compliance vendors: These audit, scan, and advise but don’t process payments.

• Hosted payment field providers: These offer a payment form that captures card data on a domain the provider controls instead of the business’s site.

• PCI consultants: These advise on strategy rather than infrastructure. They help a business figure out which SAQ applies, prepare documentation, and interpret requirements.

What services do PCI compliance service providers offer?

Many compliance-focused providers offer a combination of services.

Here’s the range of services in the industry:

• Tokenization: Replacing sensitive card data with a token that has no exploitable value outside the provider’s system. This pulls cardholder data out of a business’s environment.

• Hosted payment fields: Serving the payment form directly from the provider’s domain rather than the business’s site. This means raw card numbers don’t pass through the business’s servers.

• Scope reduction consulting: Mapping where cardholder data flows through a business’s systems and pinpointing which components can be removed from that flow.

• Security assessments: Conducting formal reviews, often run by a QSA, that test whether a business’s controls meet each PCI DSS requirement.

• Vulnerability scanning: Running quarterly external scans run by an ASV. This is required for any business or provider with systems that touch cardholder data over the internet.

• Penetration testing: Completing annual, more adversarial testing that simulates an attack against network segmentation and application-layer defenses.

• Ongoing compliance monitoring: Tracking file integrity, access logs, and configuration drift. PCI DSS 4.0.1 pushes providers toward continuous validation instead of a once-a-year checkbox.

How do you evaluate a PCI compliance service provider?

Effective scope-reduction tools share a common mechanism: they keep cardholder data away from your servers rather than try to secure it once it arrives there. Ask how the provider’s integration changes your PCI footprint. Does its hosted fields or tokenization move you into a simpler SAQ category, or does card data still touch your systems along the way? If card data passes through your infrastructure at any point, even briefly, your scope stays larger than if the data never arrives there in the first place.

The provider’s documentation should lay out the exact compliance responsibilities it assumes versus what stays with the business. Read through this information rather than relying on a sales conversation to describe it. Look into these categories before committing to a provider:

Certification status

Confirm the provider appears on the Visa Global Registry of Service Providers or the equivalent Mastercard list. Check the date of the provider’s most recent Attestation of Compliance. Certification lapses annually, so it must be actively maintained.

Data handling and tokenization approach

Find out whether the provider tokenizes at the point of collection or only after data reaches its servers. Ask how tokens are scoped, whether they’re reusable across transaction types, and what happens to the underlying data once a token exists.

Integration complexity

A provider with clear documentation and drop-in components, such as prebuilt payment forms, typically means your team doesn’t need to secure and maintain as much custom code. This narrows your PCI footprint.

Geographic coverage and ongoing support

PCI DSS applies anywhere those card networks are used, and any business that stores, processes, or transmits data for those cards must comply, regardless of country. However, local data residency and privacy laws, regional card scheme rules, and provider coverage vary by region. Ask a prospective provider whether it operates infrastructure in every country where you do business and how it handles region-specific differences.

SAQ qualification

A provider should tell you which SAQ its implementation qualifies you for. A compliant integration should limit the scope of your compliance and qualify you for a less rigorous SAQ.

Stripe is a PCI Service Provider Level 1 and provides users with features to automate some aspects of PCI compliance. If a business integrates with Stripe Elements, Checkout, Terminal SDKs, or our mobile libraries, Stripe helps complete their SAQ in the Dashboard.
