Thanks very much Mika for your thoughtful response. Have you ever used the aforementioned service https://sucuri.net

Thanks Ben, We signed up for PayPal pro and purchased the Woo PP Pro plugin an. We have SSLs on all 12 sites. But there are a number of tech personnel stating that a checkout system using multi-site can be hacked even if each site has its own SSL. We are told that the only solution is that each individual site must have its own IP address (which is impossible). I’d be very greatful if a wordpress admin or person with ecommerce multi-site experience would weigh in.
