In today's cybersecurity landscape, much of the focus is placed on firewalls, antivirus software, and endpoint detection. While these tools are essential, one critical layer often goes overlooked: the Domain Name System (DNS). As the starting point of nearly every online interaction, DNS is not only foundational - it's increasingly a target.
