Operational Technology and Industrial Control System Security

Israel has developed specialized cybersecurity platforms for operational technology (OT) and industrial control systems (ICS) — the networks that control power plants, water treatment facilities, manufacturing lines, and transportation systems. Claroty (raised $100M+), SCADAfence (acquired by Honeywell), and others provide visibility, threat detection, and access control for industrial environments that were traditionally air-gapped but are increasingly connected.

The urgency for OT security was dramatically demonstrated by the Stuxnet attack (widely attributed to Israel and the U.S.) against Iranian nuclear centrifuges — paradoxically making Israel both a pioneer in OT attacks and a leader in OT defense. This dual expertise gives Israeli OT security companies an unmatched understanding of how industrial systems can be compromised and therefore how to protect them.

Strategically, OT security is becoming critical as digital transformation extends into physical infrastructure. Every smart grid, connected factory, and intelligent transportation system creates new attack surfaces with potential for physical damage and safety hazards. Israeli OT security expertise — born from understanding real nation-state OT attacks — commands premium positioning in a market projected to exceed $30 billion by 2030.
