Network Access Control (NAC)
Verify every device before it touches your network—wired, Wi-Fi or VPN.
Network Access Control enforces who and what can connect to your network. ZM Technologies deploys NAC for manufacturing plants, offices and campuses—blocking rogue devices, profiling IoT/OT and segmenting BYOD from corporate assets.
Why it matters
- Critical for TISAX (automotive), ISO 27001, IT Act 2000 compliance
- Stops rogue laptops, IoT and OT devices from joining the LAN
- Auto-segments contractor, BYOD and guest traffic
- Required for OT/IT segmentation in manufacturing plants
