SSL, HTTPS and PCI Compliance


In order to accept credit cards on your site, you must have an SSL certificate and use HTTPS on all pages that collect credit card information. This is necessary to meet PCI-DSS specs which state that if you collect payment data, you have to use SSL. However, just having an SSL certificate and using HTTPS doesn't necessarily mean that you will be fully PCI compliant. The requirements vary based on your business-type, technical setup, and/or volume. If you have PCI compliance concerns, it is best to speak with your payment processor or a PCI-DSS expert. This article (http://tomkconsulting.com/news049-PCI-Overview.htm) is a good primer on the subject and can help you understand what, if any, additional steps you'll need to take.


HTTPS provides authentication for your website and associated web server, which protects against man-in-the-middle attacks. Additionally, it provides bidirectional encryption of communications between a customer's browser and your server, which protects against eavesdropping and tampering with and/or forging the contents of the communication.


Please review our article Securing Your Site with HTTPS for specific steps and tools to help check and improve the security of your site as well as more information on how to go through basic security procedures for your checkout pages.



MemberMouse Security Features


MemberMouse uses tight security protocols for password, licensing and payment transactions. MemberMouse doesn't store your customers' payment details instead they are stored on your payment processor's servers. There are also some extra settings you can tweak to add to the security features of the plugin and payment handling:  

  • Account Sharing Protection (enabled by default) allows you to limit the number of IP addresses that can access an account over a 24 hour period.  
  • Configuring Stripe to use stripe.js will send credit card and billing information directly to stripe so it never touches your server.
  • Configuring Authorize.net CIM will enable the customer information manager that stores customer details on the Authorize.Net servers. Additionally, the Accept.js token exchange has been incorporated into our Authorize.net CIM integration so credit card and billing information is sent directly to Authorize.net and never touches your servers.
