VPN Devices

VPN devices are used to secure network communications and enable encrypted remote access to private networks in industrial, commercial, and enterprise environments. Commonly deployed as VPN routers, gateways, or concentrators, these devices create protected tunnels between users, remote sites, and centralized networks. By encrypting data traffic, VPN devices help prevent unauthorized access while supporting secure communication over public or private internet connections.

In industrial settings, VPN devices are often installed inside NEMA-rated enclosures to ensure reliable operation in challenging environments. Many deployments utilize NEMA Type 12 enclosures to protect networking equipment from dust, dirt, and non-corrosive liquids commonly found in manufacturing facilities. Stainless steel enclosures are also used in applications requiring enhanced corrosion resistance, such as food and beverage processing, pharmaceutical production, and other washdown-prone environments. Proper enclosure selection helps maintain network availability while protecting sensitive security hardware.

Hardware-based VPN devices typically integrate firewall functionality, strong encryption standards, and user authentication to maintain network integrity. These solutions are well-suited for continuous operation and are commonly used to support remote employees, distributed facilities, SCADA systems, and industrial automation networks. When combined with appropriate NEMA enclosure ratings, VPN devices can be safely deployed closer to the edge of the network, even in harsh or industrial locations.
