PCI stands for Payment Card Industry. Five major credit card companies form the PCI council. This council came up with a set of security standards in order to ensure that credits are processed consistently and securely. Merchants that are accepting credit cards on their website are responsible for annual PCI security scans. In a nutshell, PCI scanning is when an approved scanning entity checks your website for holes and vulnerabilities. Our Professional and Enterprise plans do include PCI Scanning that is already done on our Payline Shop servers. Our starter plan does enable you to do PCI Scanning yourself which we can assist with as well as an additional option.
