Ransomware, supply chain attacks, and IT/OT convergence mean one thing for critical infrastructure: being “compliant” is no longer enough to keep the lights on. Traditional, firewall‑centric security still leaves hidden paths into OT—and attackers only need to find one.
In this Best Practice Report, Forrester explains how Zero Trust helps detect threats faster, limit lateral movement, and keep essential services running during an incident.
When you pair these principles with hardware‑enforced, one‑way data flows in OT, you get:
- Guaranteed one‑way protection between OT and higher‑risk IT/cloud
- Fewer outages and smaller blast radius when IT is compromised
- Safe OT‑to‑cloud and OT‑to‑AI integrations without exposing control systems
