Overview of PCI Compliance
PCI compliance refers to standards instituted by the PCI Security Standards Council which is a council formed by major credit card brands. Compliance with the standards is enforced by the individual credit card brands. If you will be processing and/or storing people's credit cards, PCI compliance is required. You may be working with a card processing company that needs you to show that your website is PCI compliant.
Is Web Hosting Hub PCI compliant?
Most shared web hosts won't be able to be PCI compliant as they have many different customers running many different configurations of software on a single server. Also server-wide settings such as open ports that would need to be closed for PCI compliance can't be done on many shared web hosting servers due to them being needed by other customers. Typically you'd want to find a alternative host, preferablly one that has VPS (Virtual Private Server), or dedicated server hosting if you need to pass PCI compliance. That way the entire server environment can be adjusted just for the purpose of your one website to meet the PCI requirements.
Alternatives to PCI Compliance
For some e-commerce merchants, processing and storing credit cards is not desirable. If you do not wish to go through the steps required for PCI compliance or be responsible for the storage of credit card data; you may want to consider an alternate payment solution. Many site owners use a service such as PayPal, Google Checkout, or Checkout by Amazon. These alternatives take over the processing and storage of credit card data by having your site handing off the checkout process to their site instead.
