Critical infrastructures are radically transforming on an unprecedented scale, boosted by a rapid adoption of ‘smart’ operational technologies. Cybersecurity is a growing part of that evolution.
ABI Research forecasts security spending for the protection of critical infrastructures will hit US$125 billion globally by 2023.
Currently, defense contractors (Lockheed Martin, BAE Systems, Harris, Northrop Grumman), industrial OEMs (Honeywell, Siemens, Airbus, Rockwell, Boeing), tech leaders (IBM, Amazon, Microsoft, Verizon), and energy companies (Shell, Total, Exxon) are the big security spenders.
Three primary drivers are pushing better digital security in sectors such as utilities, transport, and healthcare: digital transformation and increased connectivity of operational technologies; democratization of cyber attacks targeting critical infrastructure; and a maturing market for industrial and IoT security.
