V. Recommended Industry-Scenario Combinations

VI. Selection Pitfall Avoidance Guide

1. Missing VPN Functionality: Needing remote access but selecting non-VPN models → Verify "VPN" in the model name (e.g., 2700639 vs. 2700640) for secure remote connectivity.
2. Form Factor Mismatch: Industrial PC integration using standalone appliances → Choose PCI/PCIE series (e.g., 2701278) for embedded security.
3. Compliance Neglect: Critical infrastructure using non-IEC 62443 models → All current FL MGUARD variants comply with IEC 62443-3-3; select K2 variants (1073943) for automotive compliance.
4. Analog System Oversight: Legacy analog devices using standard models → Choose RS VPN ANALOG (2989718) to secure both analog and digital signals.
5. Throughput Underrating: High-traffic IIoT networks using low-speed models → Select RS4000/GT series (e.g., 2701877/2700198) for gigabit throughput.
6. License Expiry: Failing to renew firmware/VPN licenses → Plan for license renewal (2702193/2701356) to maintain security updates.
7. Centralized Management Need: Multi-device deployments without CENTERPORT → Pair with FL MGUARD CENTERPORT (2702547) for unified control.
8. Ruggedness Gap: Field deployments using non-rugged models → Choose RS-B/RS2000 TX/TX-B (2989899/2702139) for harsh environment resilience.
