We're focused on entities that manage 20-100+ networks representing retail, restaurants, hotels, chains, public spaces, etc.
These networks also need protection, and can benefit from centralized management that a cloud-based solution brings over on-premise boxes. Our biggest competitor is OpenDNS, but especially since being acquired by Cisco, they're focused on the enterprise, pricing these users out of the solution.
We're utilizing a small subset of cloud providers who can support our BGP anycast network (12 POPs next week!), and have built out amazing infrastructure, an easy-to-use management interface with the stats these providers need, comprehensive categorized domains and up-to-date threat sources. We're in private beta right now and negotiating partnerships in the space.
