In light of the increasing frequency and size of cyber attacks, internet security is becoming increasingly important. The danger exists in particular when devices communicate with malicious websites and thereby potentially download harmful content or disclose personal data. This can not only lead to significant data loss, but also to the devices themselves becoming unusable or even the entire network environment being endangered. Therefore, there is an urgent need to find a solution that prevents devices from interacting with these harmful websites. This solution should be effective, able to respond in a timely manner, and not overload the existing security infrastructure of a system.
