Routers supporting **ZTA** principles implement **micro-segmentation**, **continuous authentication and authorization**, and **least privilege access** to all resources, significantly enhancing industrial network security.
* **Secure Boot and Firmware Signing**: As mentioned, these features are paramount. **Secure boot** ensures the device starts with trusted software, and **firmware signing** verifies the authenticity and integrity of updates, protecting against malicious firmware injection.
* **Advanced Firewall Capabilities**: Beyond basic packet filtering, look for features like **stateful inspection**, **application-layer gateways (ALGs)** for common industrial protocols (e.g., **Modbus TCP**, **Ethernet/IP**), and **intrusion detection/prevention system (IDS/IPS)** functionality integrated directly into the router for real-time threat blocking.
* **Multiple VPN Protocols Support**: A robust industrial 5G router should support a range of secure VPN protocols, including **IPSec (with IKEv2)**, **OpenVPN**, and ideally **WireGuard**, to provide flexibility and strong encryption for various deployment scenarios and interoperability with existing VPN infrastructure.

* **Advanced Authentication Mechanisms**: Support for **IEEE 802.1X** for port-based network access control, integration with **RADIUS/TACACS+** servers for centralized **AAA management**, and mandatory **MFA** for administrative access are crucial.

* **Centralized Security Management Platforms**: For large-scale industrial deployments, the ability to manage, monitor, and update multiple routers from a **centralized cloud-based platform** is invaluable. This platform should offer features like **configuration management**, **firmware updates**, **security policy enforcement**, and **real-time alerting**.

* **Redundancy and Failover Mechanisms**: While primarily an availability feature, redundancy also contributes to security by ensuring continuous operation even if a component fails or is compromised. Look for features like **dual SIM support**, **WAN failover (5G to Ethernet)**, and **VRRP (Virtual Router Redundancy Protocol)**.

* **Industrial Certifications**: Beyond security-specific standards, ensure the router has relevant industrial certifications like **IEC 61000** for EMI/EMC, **UL/CSA** for safety, and appropriate **IP ratings** (e.g., **IP67** for dust and water resistance) for the intended operational environment.
