Any environment with managed switches or wireless infrastructure benefits from zero-trust NAC.
Every device authenticates via 802.1X with Entra ID credentials before reaching the LAN. Finance, HR, and IT land on separate VLANs automatically — no manual switch port configuration required.
Challenge: Flat networks where any connected device can reach any server. PortGuard enforces identity-based microsegmentation without replacing existing switching infrastructure.
Reception generates time-limited vouchers in seconds. Guests connect, enter the code on the captive portal, and land on an isolated VLAN with bandwidth controls — completely separated from the corporate network.
Challenge: Providing guest internet access without exposing the corporate network, without an IT technician on site for every event.
Register approved MAC addresses for PLCs, cameras, and IoT devices. Any unknown device hitting the network triggers an immediate rogue MAC alert and auto-block. CVE scanning flags unpatched firmware.
Challenge: IoT and OT devices cannot run 802.1X supplicants. They need MAC-based auth with strict monitoring.
Law firms and financial advisors handle sensitive client data. PortGuard ensures only authenticated, compliant devices reach document management and CRM systems — with full audit trail for regulatory requirements.
Challenge: Regulatory requirements (GDPR, ISO 27001) demand proof of who accessed which network segment and when.
Managed Service Providers run PortGuard Enterprise as a shared platform. Each client gets an isolated tenant with its own policies, VLANs, and portal. Single pane of glass for monitoring all sites.
Challenge: MSPs need to offer NAC as a service to multiple clients without deploying separate infrastructure for each.
Universities and schools enforce role-based network access: students on one VLAN, staff on another, IoT devices (projectors, printers) on a third — all driven by directory group membership.
Challenge: Thousands of personal devices (BYOD) mixed with managed devices, all needing appropriate network access.
PortGuard works on any RFC 3580-compliant infrastructure. If you have managed switches or a wireless controller, it works.
