SEO Sink vs WP Defender
WP Defender is WPMU DEV's WordPress security plugin: hardening, firewall, malware scan, audit log — the application layer again. It guards the house; it doesn't see the people poisoning your reputation in the street.

The one-line verdict
WP Defender hardens the CMS. SEO Sink defends what the CMS can't see: your rankings, your analytics, your idle domains.
Harden your WordPress with whatever plugin you like — then ask what's protecting your rankings. If the answer is "nothing", that's the layer we sell.
