What is DNS Filtering and Why Use It?
DNS is an acronym for Domain Name System, which permits us to access websites using their names, like Yellcom.net. DNS converts the name to a form that computers and networks can understand. DNS Filtering is a service that blocks malicious websites, applications, and inappropriate websites – as defined by your company policy. A blocked website or application cannot be accessed on your computers, smart phones, etc.
Much like our antivirus service, our DNS Filtering service is another one of our basic cybersecurity services. As explained above, there are two types of websites that we can block. The first type represents malicious websites that we block to protect your systems, data, and your personal information.
The second type depends on your company policies. Initially, these websites are not blocked. We can block those categories as defined by your corporate policy. This discussion would be part of our on-boarding process.
