I can't tell for sure either. Their pages about it, as usual, are heavy on marketing and light on technical details. In one case it looks like they offer a CloudFlare-like service (http://cloudproxy.sucuri.net/features http://cloudproxy.sucuri.net/features), and then in another case, they offer it as a Wordpress plugin (https://wordpress.org/plugins/sucuri-cloudproxy-waf/faq/ https://wordpress.org/plugins/sucuri-cloudproxy-waf/faq/) (and presumably for other platforms too). Given modern web development trends though, I'm sure they'll be very successful at selling their product without bothering with things like technical details.
