Before we talk about protection, you need to understand the DNS. The domain name system (DNS) works like a phone book for the internet. When a user enters text into a browser, DNS servers take that input and translate it into the unique internet protocol (IP) addresses that let the browser open the desired site. But DNS protocols were never designed with security in mind, and are highly vulnerable to cyberattacks, such as cache poisoning, DDoS, DNS hijacking, botnets, C&C, man-in-the-middle, and more.
By redirecting users’ web traffic through a cloud-based, DNS security solution, businesses and MSPs can finely tune and enforce web access policies, ensure regulatory compliance, and stop nearly 90% of threats at the network’s edge—before they ever hit the network or endpoints.
