Zero-Trust Network Fabric for Distributed Campuses

Smart campuses span headquarters, regional branches, and pop-up spaces. A zero-trust fabric keeps lateral movement in check while giving employees fast access.

Segmentation first

• Define identity-based macro segments: Corp, Guest, OT, Lab.
• Use EVPN/VXLAN to stretch segments only where they are needed, with per-site DHCP/DNS.
• Apply ACL templates via automation so every switch keeps identical guardrails.

Identity-aware edge

1. NAC enforces posture using Intune/Jamf signals plus certificate auth.
2. Micro-segmentation tags follow devices into the SD-WAN overlay, so policy is consistent on campus and at home.
3. Secure onboarding portals issue short-lived credentials for contractors and events.

Telemetry + response

• Stream NetFlow/IPFIX to the SOC and pair it with DNS sinkhole alerts.
• Use digital experience monitoring to watch hop-by-hop latency, Wi-Fi retries, and SaaS reachability.
• Automate containment by pushing switch quarantine VLANs the moment an endpoint fails posture.

We can deploy the full stack (fabric, NAC, monitoring) in 6 weeks with blueprints for Cisco, Juniper, or Aruba environments.
