Cisco creates architecture to improve security and sell you new switches

Cisco unveils Hypershield, a distributed security architecture that deploys lightweight eBPF-based "enforcement points" on servers, DPUs/SmartNICs, and future DPU-enabled switches to detect anomalies, apply compensating controls, and self-update via a live "shadow path" testing model. It emphasizes AI-fed security intelligence, reduced CPU overhead, and centralized per-workload management, positioning Hypershield as a software-defined alternative to traditional firewalls rather than reporting any specific incident.
