Whether it was a medieval castle or an ancient city-state, security meant keeping threats on the outside and creating barriers around the things that mattered most.

Firewalls and network devices became our virtual walls, defining trusted and untrusted zones, and keeping the "bad actors" at the gate. For years, this perimeter-based approach was the primary line of defense in the world of cybersecurity, establishing a digital fortress around systems and data.
