Frequently Asked Questions

When does PCI DSS apply to SaaS companies?

PCI DSS applies if you store, process, or transmit cardholder data, or could impact security of cardholder data environments. Payment-adjacent SaaS may have compliance obligations.

How can SaaS companies reduce PCI scope?

Use tokenization, redirect to hosted payment pages, or leverage payment processors that handle card data. Segmentation and scope reduction can significantly decrease compliance burden.

What SAQ type applies to SaaS platforms?

SAQ type depends on your payment integration. SAQ A for fully outsourced, SAQ A-EP for e-commerce redirects, SAQ D for direct card handling. Most SaaS companies target SAQ A or A-EP.
