The modern cybersecurity landscape has fundamentally shifted as remote and hybrid work become the norm. Traditional perimeter-based defenses are no longer sufficient as employees connect from different locations, use personal or unmanaged devices, and sometimes bypass VPNs, creating significant blind spots for security teams. DNS-layer security has emerged as a critical first line of defense, blocking malicious domains before they ever reach the network perimeter. By routing DNS requests through a single provider, organizations can enforce consistent security policies for users both on and off the corporate network, reduce alert fatigue, and build greater business resilience.
