Choosing the right VPN protocol for industrial networks isn't just about performance benchmarks—it comes down to topology, device compatibility, and operational complexity. This guide breaks down how IPsec, OpenVPN, and WireGuard work in OT environments, exploring their key differences across SCADA backhaul, PLC remote maintenance, and high-throughput video surveillance to help you find the perfect match for your industrial routers.

Connecting remote branches, headquarters, and temporary project sites usually means dealing with expensive MPLS lines or complex VPN setups that require static public IPs. This guide demonstrates how utilizing Wavetel 5 and 6 Series industrial 5G/LTE routers alongside ZeroTier creates a seamless, secure, and highly cost-effective private network layer. Discover the step-by-step deployment process, cost comparisons.
