It's simple to install & configure it for your needs - no technical knowledge required! I am not sure how often is updated but we have had issues with some of our customers' servers being down due from DoS attack (DNS poisoning).
We can see that DNS resolution has been blocked by malicious client IPs which makes us believe its because they use this service or similar services in order get access through firewall/routers without knowing them first thus causing DDOS problems. Also would be great if there were more options available under protection plans such as monthly charge vs yearly plan etc so could compare before choosing what suits best into business requirement. Protecting users experience when having online presence where customer trust matters most.
