ROI is always a tricky subject in cybersecurity. If you’re paying millions of dollars in securing your OT networks, you’d want to be able to show that it was worth it. Andrew Hural of UnderDefense talks about the need for continuous vigilance, risk management, and proactive defense, acknowledging both the human and technological elements in cybersecurity and how just because something didn’t happen doesn’t mean that it didn’t.

Zero Trust is a security model based on default-deny policies and fine-grained access control governed by identity, authentication, and contextual signals.
