Networks that brought us here won’t carry us into AI future

Agentic AI creates three distinct demands on network infrastructure.

AI models will increasingly use enterprise data rather than internet data.

Networks must reach every operational corner and connect IoT devices, sensors, cameras, and OT.

Data movement patterns will shift dramatically, producing high-volume flows across the organization.

Security becomes exponentially more complex—sensor and AI-agent identity and access, plus quantum threats; newer Cisco devices include quantum-secure boot, management access, and encryption; phased refreshes can extend lifecycles as many networks face end-of-support.
