Scaling Disruption: What the Next Cyber Strategy Must Get Right

A diversified operational technology (OT) cybersecurity monitoring platform plays a key role in strengthening the protection of cyber-physical systems by providing clear visibility, real-time threat detection, and proactive risk mitigation. By integrating multiple monitoring tools and technologies, organizations can build a layered security approach that minimizes vulnerabilities, improves response times, and keeps critical systems resilient against cyber threats.
