# Client-side security and PCI DSS compliance

Last updated Aug 24, 2026|Copy as Markdown|[View as Markdown](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/client-side-security/reference/pci-dss/index.md)|[Agent setup](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/agent-setup/)

You can use Cloudflare's client-side security for PCI DSS v4's client-side security requirements (items 6.4.3 and 11.6.1).

Refer to the [PCI DSS v.4.0 Evaluation ↗](https://cfl.re/4dhk8Gx) whitepaper for details on how you can use Cloudflare's client-side security to meet the new v4 requirements.

Note

To help with PCI DSS requirements, you must have Client-Side Security Advanced. Refer to [Availability](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/client-side-security/#availability) for details on what is included in each package.
