In light of increasing cyber threats, it's urgently necessary to have an effective security tool that blocks both spyware and deceptive websites. Since many of these threats operate at the DNS level, a security solution that works at this level would be particularly effective. Therefore, I'm looking for a tool that provides this level of security and is updated in real time to protect against the latest threats. At the same time, this tool should strengthen a system's existing security infrastructure. Moreover, it should be suitable for both individuals and businesses to improve their overall security on the internet.

The free tool Quad9 can fulfill all these requirements. It provides enhanced cybersecurity by working at the DNS level and preventing users from accessing known harmful websites. This prevents hardware devices from communicating with dangerous locations. Quad9 updates its security information in real time and utilizes threat information from various sources to provide optimal protection features. It strengthens the existing security infrastructure of a system, thereby improving comprehensive online protection against cyber threats. Quad9 is suitable for both individuals and businesses and can significantly improve overall internet security.
