PCI-compliant caching

We have designed Fastly's core CDN service with Payment Card Industry Data Security Standard (PCI DSS) compliance in mind. With proper authorization on your account, you can use Fastly's beresp.pci VCL variable to automatically cache content in a manner that satisfies PCI DSS requirements.

Adding the beresp.pci variable to an object prevents writing of that object to non-volatile disk storage on the edge. Combined with frontend and backend TLS, this feature allows you to cache and transmit flagged content through the Fastly network in compliance with our PCI certification.

Contact sales-ecommerce@fastly.com for more information on how to enable this feature for your account.
