The history of Digi International: origins, milestones and its 2026 business

Digi International was founded in 1985 as DigiBoard and became known for multiport serial communications hardware that connected many terminals and devices to computers.

How Digi International developed

It went public in 1989 and gradually moved from PC expansion hardware into embedded networking, cellular routers, remote device management and industrial Internet of Things technologies. Acquisitions further expanded its networking and infrastructure portfolio.

Digi International in 2026

By 2026, Digi provided industrial connectivity products and software for remotely managing routers, gateways and connected equipment.

Why the history matters

Its long evolution mirrors industrial networking itself: proprietary serial links gave way to Ethernet, cellular and cloud-managed IoT systems while many operational devices still needed reliable connectivity for years at a time.
