The page does lead off by telling you it is a software load balancer, but I agree, we can do a better job of giving more information on the product itself. Most people who pursue HAProxy Enterprise are already familiar with HAProxy. With that said, we're actually working on a complete overhaul to this page and I believe the new version will address this.
