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.

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.

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.

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.

Secure Remote Maintenance With MRC

The Moxa Remote Connect (MRC) service offers an easy-to-use, secure, cloud-based option for remote maintenance and access. The OnCell G4300-LTE4 Series acts as an MRC gateway that enables safe remote monitoring of end devices connected to the same local area network (LAN) using the MRC server and OnCell routers in service. MRC implements multiple access control methods to safeguard assets, data, and remote operations. With MRC, engineers can perform maintenance and troubleshooting remotely, ensuring continuous operation across distributed environments.
