Mike Shapiro on "Multisite-Woocommerce-Paypal Question"

We have 12 sites (using individual domains)under a parent domain using WP Multisite. We are running woocommerce and sell various jewelry pieces on all of the sites. We have been told that (due to security issues) we can only accept checkout payments using paypal standard.
Also, we are advised that the only way to avoid hacking issues is to provide each site with its own SSL. And the only way to accomplish this is to assign each site its own unique ip address. BTW, we currently have ssls in place for all sites. I have been working this problem for 6 weeks now and any advice would be greatly appreciated. We bought the Woocommerce Plugin for Paypal pro plugin. We would like to use Paypal Pro or Paypal Advanced for checkout because Paypal Standard looks amateurish.
