CyberX was an Israeli cybersecurity company founded in 2013, specializing in securing industrial control systems (ICS) and operational technology (OT) environments. The firm developed innovative solutions for threat detection, vulnerability management, and network monitoring in critical infrastructure sectors such as energy, manufacturing, utilities, and transportation. CyberX's platform utilized passive network monitoring and machine learning to identify anomalies and cyber threats without disrupting operations, making it a key player in protecting against sophisticated attacks on industrial networks. The company gained recognition for its expertise in simulating and analyzing ICS protocols, helping organizations comply with standards like NIST and IEC 62443. Headquartered in Tel Aviv, CyberX expanded globally, serving over 100 customers worldwide, including major enterprises and government entities. Its technology was particularly valued in high-stakes environments vulnerable to nation-state cyber threats, such as those seen in incidents like Stuxnet. In June 2020, Microsoft acquired CyberX for approximately $165 million to bolster its Azure Defender for IoT offerings, integrating CyberX's OT security capabilities into Microsoft's broader cybersecurity portfolio. Post-acquisition, CyberX's team and technology were absorbed into Microsoft, enhancing the company's defenses for industrial IoT and hybrid environments. The acquisition underscored the growing importance of OT cybersecurity amid rising industrial cyber risks. CyberX's founders, Amir Zilberman and Nir Giller, brought backgrounds from elite Israeli intelligence units, contributing to the company's strong technical foundation. While no major controversies are associated with CyberX, its Israeli origins have occasionally drawn scrutiny in geopolitical contexts regarding cybersecurity tool exports.
