Lumu and DNS firewalls are different technologies, designed with different purposes in mind.

For starters, Lumu is a technology that was built from the ground up with a single objective: help to measure and understand your unique compromise level in real time. This is done via Lumu’s patent-pending Illumination Process which systematically collects, normalizes, and analyzes your company’s network metadata, resulting in the identification of enterprise assets in contact with adversarial infrastructure. Simply put, Lumu identifies confirmed compromises.

On the other hand, a DNS firewall is a network security solution that prevents network users and systems from connecting to known malicious internet locations. DNS firewalls work by employing DNS Response Policy Zones (RPZs) and correlating them with threat intelligence.
