Open DNS is an online security web app that lets you browse the internet faster while still being safe from phishing and malware sites. Unlike some DNS apps, Open DNS is accessed online by simply logging into your account on its site. You can use this app for small businesses and households with children, as well—Open DNS allows you to block users from certain content online by entering your preferences on your account. Open DNS features cloud service, customizable filtering of content, parental controls for every device, phishing, malware, and botnet protection, and premium DNS, as well. This is an easy-to-use and reliable app to have if you are active with your browser use.
