Re: seems unrelated
Cloudflare works by taking over your domain's DNS hosting, then rerouting (some) hostnames to their own server farms to intercept, cache and filter HTTP traffic. (Unless you pay them extra to continue using your own DNS service and only rely on them for HTTP, a pricing model that makes very little sense to me.)
The Verisign offering also works by replacing your DNS servers, but that seems to be as far as the commonality goes: this replaces your *recursive* DNS server, making it a competitor to OpenDNS (as recently acquired by Cisco) rather than Cloudflare.
