AI infrastructure has a networking problem, zero-trust overlays can help

AI workloads are fundamentally distributed across multi-cloud GPU clusters, edge devices, and partner APIs, but traditional networking approaches like VPNs and IP-based firewalls were not designed for this complexity. Security incidents and exposed AI components are rising sharply, while nearly half of organizations lack networks capable of supporting AI bandwidth and latency requirements. Zero-trust overlay networking, which ties identity to cryptographic certificates rather than IP addresses, offers a more robust and consistent security model for distributed AI infrastructure.
