Voltra Fabric paired with the Digi Ventus managed service for cellular routers gives site owners a dependable connection from every device to the software that runs it
MINNEAPOLIS, MN, November 13, 2026 — Digi International (NASDAQ: DGII, www.digi.com), a leading global provider of wireless WAN connectivity products and services, and Voltra today announced a collaboration that pairs Voltra Fabric with Digi Ventus. Fabria is Voltra's platform for connecting, modeling and coordinating every device on a site. Ventus is Digi's fully managed connectivity service built around Digi cellular routers. Together, the two companies give site owners and operators a dependable connection from every piece of equipment to the software that runs it, so they can manage peak demand, control costs and add new assets with confidence.
Where Site Projects Slow Down
A modern site combines chargers, batteries, meters, solar inverters and building systems from many vendors, often installed years apart. Each speaks its own protocol, many arrive with their own modems and data plans, and the site's local network usually belongs to someone else. Before any energy savings can happen, every device has to be and remain reachable.
What Each Company Brings
Voltra Fabric connects to every device on a site, whatever the vendor mix, and models the whole site as one live digital twin with its real structure and limits. Teams configure setpoints, interlocks and fail-safes from that model, and Fabric keeps the connection, model and configuration current as equipment and firmware change. Voltra's charge and load management run on top of it, as can the tools a customer already uses.
Digi provides the link that keeps the site reachable. Digi Ventus is a fully managed connectivity solution built for uptime, bundling Digi 4G and 5G routers, multi-carrier cellular data and 24/7 monitoring into one monthly subscription. Digi IX25 5G router delivers secure 4G and 5G connectivity independent of the site's own network, while Digi Ventus monitors and manages them so the site stays online. In terms of security, the Digi Ventus Genesis monitoring platform has completed a SOC 2 Type 2 audit, and the routers support FIPS 140-3 validated cryptographic modules. The routers also include firewall, network segmentation, VPN encryption and logging features that help customers meet PCI DSS requirements.
On site, a Voltra site controller connects to the local equipment, and a Digi gateway in the same cabinet carries the controller's connection to Voltra Fabric over cellular. The gateway's status appears in Voltra's platform next to the equipment it connects, so when something goes offline, a team can see right away whether the cause is the connection, the controller or the device behind it.
"Every site project starts with the same question of whether the equipment can be reached, Digi answers it with connectivity that utilities and industrial operators already trust," says Alexander Stratmoen, Co-founder and CEO of Voltra"Our customers start from a site that is connected and stays connected, and Voltra Fabric turns everything on it into one live model on which they can act."
"Successful energy projects depend on more than energy. They require reliable connectivity across the entire site," said Tony Puopolo, President, Digi Managed Solutions. "Digi makes wireless secure, simple and reliable, complementing Voltra's ability to coordinate complex energy projects. Together, we're helping utility and industrial customers simplify deployments and build smarter, more connected infrastructure."
