Beyond the Perimeter: Why Edge Security Requires a Fundamentally Different Threat Model

Edge computing is expanding rapidly, but traditional perimeter-based security collapses at distributed endpoints operating outside centralized control.

Organizations treating edge security as a checklist item face exposure that encryption alone cannot mitigate.
