It helps reduce the burden on downstream controls by filtering risky domains early, where the cost of remediation is lowest. The result is stronger protection for remote users, branch offices, and distributed teams that depend on consistent access to business applications.

It supports a layered defense strategy by adding visibility and enforcement at one of the most frequently abused points in the attack chain. For buyers comparing options, the value is straightforward: more control over outbound risk, less noise for security teams, and better continuity for the firewall investment already in place.
