IT-OT convergence creates security vulnerabilities traditional defenses cannot address

Kerravala argues that the convergence of IT and OT systems has fundamentally broken the traditional security model, and that organizations cannot rely on 'top notch technologies' alone to protect hybrid environments. He contends that digital transformation has created unprecedented operational efficiency gains, but only a complete reassessment of security strategy—not incremental technology upgrades—can close the critical gaps this convergence exposes.

The Convergence of IT and OT Systems Requires a Complete Reassessment of Security

This world of digital transformation means the convergence of Information Technology (IT) and Operational Technology (OT) has opened up unprecedented opportunities for operational efficiency. However, this utopia comes with its own Pandora’s box: more vulnerabilities that attract hackers. The antiquated strategy of top notch technologies for security is no longer sufficient. What’s needed is…
