IT-OT convergence creates security gaps traditional defenses cannot address

Kerravala argues that the convergence of IT and OT systems has fundamentally broken traditional security models, requiring organizations to completely reassess their defensive posture rather than incrementally upgrade existing technologies. The operational efficiency gains from digital transformation are negated by exponentially expanded attack surfaces that legacy security architectures were never designed to protect.

unprecedented vulnerabilities attracted by operational efficiency gains

Merging IT and OT systems exposes critical security gaps that traditional defenses cannot protect against alone.

This utopia comes with its own Pandora's box: more vulnerabilities that attract hackers.
