Reinforce Your Cybersecurity With Moxa's Secure Cellular Routers

The OnCell G4300-LTE4 Series cellular routers are engineered to provide uninterrupted connectivity and robust cybersecurity in industrial environments. Featuring an industrial-grade design and Moxa’s GuaranLink cellular link auto-recovery, these cellular routers keep your critical operations running smoothly, even in the toughest conditions. To protect against cyberthreats, the OnCell G4300-LTE4 Series is equipped with built-in security features, including secure boot, VPN, NAT, firewall, and Deep Packet Inspection (DPI) for endpoint protection and data security.


In addition, the OnCell G4300-LTE4 Series supports Moxa Remote Connect (MRC), a secure cloud-based solution for centralized monitoring and remote access to field devices, boosting management and maintenance efficiency.

Guaranteed Reliable Cellular Links With GuaranLink

Maintaining reliable cellular network connectivity is a constant challenge for industrial applications. This is especially true for mission-critical applications, such as real-time remote monitoring of power grids, pipelines, and traffic control centers. Moxa's OnCell products support GuaranLink for seamless and reliable cellular connectivity. GuaranLink uses a customized cellular auto-recovery process to maximize uptime, minimize data loss, and reduce on-site maintenance costs.

Build a Cybersecurity Shield for Your Critical Applications

Secure Boot

Secure boot ensures that the device only boots up using software that is signed and trusted by the manufacturer. By guaranteeing system integrity and protecting against tampering attacks, secure boot provides an important layer of defense for remote and critical infrastructure.

Virtual Private Network (VPN)

A trusted VPN lets you create an encrypted network environment to protect your sensitive data from unauthorized access.

Deep Packet Inspection (DPI)

By scanning traffic patterns, DPI only allows approved communication patterns to access devices, while unauthorized attempts—such as unexpected remote connections—are automatically blocked.

Firewall and Network Address Translation (NAT)

The firewall with built-in DDoS protection enforces security policies based on IP, protocol, and traffic behavior to identify potential threats. Meanwhile, NAT reduces the need for IPv4 publishing addresses and hides private network address ranges.

Secure Remote Maintenance With MRC

The secure, cloud-based Moxa Remote Connect (MRC) service simplifies remote access and maintenance. The OnCell G4300-LTE4 Series can act as an MRC gateway, allowing you to remotely monitor connected end devices within the same LAN through the MRC server and distributed OnCell devices. To minimize potential security threats, MRC provides several types of access control to protect your data, assets, and remote operations. With MRC, seamless remote maintenance and troubleshooting for field devices is a breeze.
