Hellgate reduces your scope by keeping card data out of your systems. Guardian, a PCI DSS Level 1 certified vault, stores cardholder data inside a certified environment operated by Hellgate; your systems handle only non-sensitive tokens. The Web, iOS, and Android SDKs capture card data on the client and tokenize it, so raw PANs never reach your servers.

The practical outcome is often a move from SAQ D to a much lighter SAQ A or SAQ A-EP.
