Our range of rugged routers, often equipped with VPN functionalities, are built to support such advanced management features, ensuring reliable and secure remote access for ongoing operations.
A VPN Router offers significant advantages for Internet of Things (IoT) deployments, particularly when it comes to security and centralized management. By routing all IoT device traffic through an encrypted tunnel, a VPN router protects against unauthorised access and cyber threats, which is crucial given the often-limited security features of individual IoT devices.
Furthermore, a VPN Router simplifies network management for IoT ecosystems. Instead of configuring each device individually, all devices connected to the router automatically benefit from the VPN’s security protocols. This ensures consistent protection and allows for secure remote access to IoT devices, which is vital for monitoring and control in various applications.
A VPN router enhances your internet connection by encrypting all traffic flowing through it, offering a secure and flexible network. However, it’s important to understand that a VPN router primarily adds a layer of security and privacy on top of an existing internet connection. It doesn’t inherently provide the internet connection itself in the way fixed broadband does.
For situations where fixed broadband is unavailable or unreliable, solutions such as 4G and 5G routers can act as primary internet sources, providing robust cellular connectivity. When combined with the capabilities of a VPN, such as those offered by a Rugged VPN-enabled router, you gain both internet access and enhanced security for all connected devices. This setup is particularly beneficial for remote sites, mobile deployments, or as a failover for traditional broadband.
Therefore, while a VPN router is crucial for securing your network, its ability to replace fixed broadband depends on whether it’s integrated with a cellular modem or used in conjunction with a separate internet access method.

Digi builds security into its connectivity platform through Digi TrustFence, which provides secure boot, encrypted connections and device authentication. It appears across the range, including the Connect EZ serial device servers and IX-series routers. Several models add FIPS 140-2 cryptography, for example the IX40-05, and support VPN tunnelling through IPsec with IKEv1 and IKEv2, OpenVPN client and server, and GRE, alongside stateful firewalls, MAC filtering and VLAN support. Authentication options include RADIUS, TACACS+ and certificate-based access. This layered approach suits critical infrastructure and SCADA deployments where the connection itself is part of the attack surface. As security feature sets vary between routers, serial servers and USB products, verify the specifics on the individual product page.
Digi Connect EZ serial device servers exist to connect legacy serial equipment to modern IP networks without replacing the underlying machinery. The range on rugged.co.uk runs from single-port units up to the eight-port EZ08-TS00, with software-selectable RS-232, RS-422 and RS-485 on each port.
