IT-OT convergence creates security blind spots traditional defenses cannot address

Kerravala argues that the merger of Information Technology and Operational Technology systems has fundamentally broken the traditional security model, and that top-tier technologies alone can no longer protect against the new class of vulnerabilities this convergence creates. Organizations must completely reassess their security strategy—not incrementally patch it—because the attack surface has expanded beyond what legacy defenses were architected to handle.
