Network Access Control.
Device posture and identity checked before network access is granted — particularly important on shared, guest or lab network segments.
01 Problem
Any device that can plug into a switch port or join Wi-Fi and reach internal resources is a network with no real access boundary, regardless of what the firewall does at the edge.
02 Solution
NAC policy that authenticates and checks device posture before granting network access, integrated with your existing identity provider.
- NAC deployment and policy design
- RADIUS integration
- Device posture checking
- Guest and BYOD segmentation
- Integration with Active Directory / identity provider
03 Architecture
Devices authenticate via 802.1X or MAC-based fallback where required, are placed into the appropriate VLAN by policy, and posture-checked before full access is granted.

05 Methodology
Start in monitor-only mode to understand what's actually on the network before enforcing policy, then move to enforcement in stages.
06 Outcome
A network where 'what's connected' is a known, enforced fact rather than an assumption.
07 FAQ
Will this break existing devices that can't do 802.1X?
No — a fallback path (MAC authentication bypass, sandboxed VLAN) is designed in for devices that genuinely can't support it, rather than leaving them unmanaged.
How long does NAC rollout take?
Monitor-only discovery typically runs for a period before enforcement, so the actual timeline depends on what's found.
