[Coleman Technologies Blog](https://colemantechnologies.com/blog/categories/blog) [Coleman Technologies Admin](https://colemantechnologies.com/blog/blogger/darren-coleman) Saturday, 24 July 2021 Did you know that more than[ 90% of cybersecurity incidents](https://chiefexecutive.net/almost-90-cyber-attacks-caused-human-error-behavior/) can be traced back to human error? Just one wrong click on a dangerous link or unknown website is all it takes to download dangerous malware and infect your systems. That’s why you need to employ every tool available to you to mitigate the risks facing your business. Case in point — do you have a DNS filter? ### What Is A DNS Filter? A DNS filter is a [software](https://www.colemantechnologies.com/blog/why-is-it-super-important-to-keep-your-software-updated/ "software") solution that actively blocks access to or interaction with dangerous content online. When business devices try to access a website, the DNS filter looks up the destination to determine if the site is deemed safe or potentially unsafe. More advanced filters can even prevent users from clicking a suspected dangerous link. By blocking unsafe websites and content, DNS filters dramatically limit the risk posed by unaware users. These solutions can be deployed both at home and at work to avoid unnecessary risks and minimize or eliminate malicious attacks that threaten to take down your entire system. ### A DNS Filter Will Help You Fight Ransomware The primary benefit of a DNS filter is protection from ransomware by blocking uncategorized sites. Ransomware can infect your systems in a variety of ways, gaining access to your system via email, a website, or even a virus. DNS filtering will block access to a range of dangerous content types, including ransomware. If a user somehow accesses a dangerous website, the DNS filter will still be able to prevent them from downloading an untrustworthy file, such as ransomware. This provides a crucial, additional layer of protection for unaware employees. ### Coleman Technologies Will Help You Fight Malware We want you to have every weapon in your arsenal ready to use to prevent cybercriminals from gaining access to your systems and disrupting valuable business time and costing you money.
