Key Topics
Common security issues in industrial IoT deployments.
Public IP Exposure
Routers on public IP SIMs are probed within minutes. Default credentials, open WebUI and SSH ports are the primary attack vectors.
Endpoint Hardening
CCTV cameras, BMS controllers, energy meters, and access control systems behind port forwards are often the real target.
VPN vs Port Forwards
Port forwards expose LAN devices directly to the internet. WireGuard and OpenVPN tunnels eliminate this risk entirely.
Private APN
Private APN SIMs place devices on an isolated network with no public IP – the most secure option for fixed industrial deployments.
