With billions of active websites available on the internet, it’s easy to see why we would need a solution designed to seek out and filter potentially dangerous websites. Web filtering seems like a simple concept, but under the surface, it’s a conglomerate of independently moving parts, systems, information and knowledge, deployed to keep us safe. In the best case user scenario, web filtering is imperceptible, filtering out dangers and risks before we even see them – but do you know what’s also designed to be imperceptible? Malware and ransomware – and one wrong click can land you and your organization in a world of trouble without a web filtering solution.
Web filtering technology restricts user access to particular URLs or websites and is manufactured for every situation from individual use to multi-national enterprise use. Enterprise-grade web filters primarily block content determined by an enterprise to be non-productive or potentially dangerous, through the use of black and white-lists. They are also able to perform an immediate analysis of the content of a page and allow or restrict access, dependant on the findings. The best web filtering solutions make use of a URL database which classifies websites as safe for use, or as a potential malware, phishing or virus host.
Web filtering uses hardware or software-based solutions to establish and maintain rules determining the types of sites that users may visit when using a network internet. Content determined to belong to time-wasting or illegal categories like gambling, adult and gaming, is blocked by the web filtering solution. Domain Name System filtering, or DNS filtering, is gaining in popularity due to its ability to filter content from web pages to determine their safety level, and potentially block them before they have a chance to infiltrate the network and attack, or before video streaming or gaming websites sap away employee productivity.
Web filtering works in a few different ways.
Enterprises rely on web filtering to keep their employees on task and compliant, and their networks clear of lurking threats. Employee use of BYOD puts enterprise networks, and thus all other users and systems, at risk of theft and attack. With the cost of attacks rising exponentially, a web filtering solution could be all that stands in the way of the failure of your business.
