Point-to-Point Encryption

Our PCI-validated P2PE solution encrypts cardholder data at the terminal, so that sensitive cardholder data never enters the merchant environment. Learn More.


We invented the industry’s first payment data tokenization solution, which replaces stored card data with a random, alphanumeric value that is useless in the hands of data thieves.

These three solutions work together to provide unparalleled protection against costly data breaches. Your customers’ personal information will always be protected — during the transaction and long after — by the most reliable payment security technologies available.

PCI DSS Requirement 12.8 —
Service Provider Management

If you retain service providers to process, store, or transmit cardholder data, you must have policies and procedures in place to manage those service providers. While there are no general guidelines to manage service providers, there are four specific PCI DSS requirements.

1. Maintain a list of service providers. (Requirement 12.8.1)

Shift4 Payments is a PCI DSS-validated Visa Third-Party Agent (TPA) and Mastercard Third-Party Processor (TPP). Shift4 Payments is not a shared hosting provider (see PCI DSS Requirement 2.4).

2. Maintain a written agreement that includes an acknowledgement that the service providers are responsible for the security of your cardholder data. (Requirement 12.8.2)

When you sign on with Shift4 Payments, the Merchant Services Agreement will specify exactly what you can expect regarding the security of your cardholder data.

3. Ensure there is an established process for engaging service providers, including proper due diligence prior to engagement. (Requirement 12.8.3)

4. Maintain a program to monitor service providers’ PCI DSS compliance status annually. (Requirement 12.8.4)
