As IT, OT, and IoT systems converge, a new era of connected operations is taking shape. The Extended Internet of Things (XIoT) now links everything from factory floors and smart grids to medical devices and vehicles, driving unprecedented efficiency and innovation. But this connectivity also brings considerable risk. Once-isolated systems are now exposed to new vulnerabilities. A single breach can halt production, compromise safety, and trigger costly downtime.

A Growing and Complex Threat Landscape

Industries like energy, manufacturing, healthcare, and transportation face rising threats as legacy systems connect to modern networks and the cloud. Cybercriminals are exploiting these new entry points, pushing organizations to strengthen defenses across both IT and OT environments. Leading companies are investing in integrated cybersecurity strategies that safeguard critical assets, ensure operational continuity, and protect people and data.

Smarter Defense Through AI and XDR

To stay ahead of evolving threats, cybersecurity providers are turning to AI and machine learning to detect anomalies, analyze data in real time, and automate responses. These capabilities are essential in environments where downtime simply isn’t an option. Meanwhile, Extended Detection and Response (XDR) platforms are transforming how teams monitor and secure connected systems. By unifying visibility across endpoints, networks, and OT devices, XDR enables faster, more coordinated defense.
