"TCP/IP's default network visibility has enabled much of today's malicious activity. Given our current threat
landscape and the widespread adoption of Zero Trust as a set of principles and best practices, we believe
that we now have an imperative to pivot our core networking technologies to a default-deny stance—one that
aligns with emerging concepts like Gartner's preemptive cybersecurity, which emphasizes denying, deceiving,
and disrupting threats before they can launch or succeed."
