Every name tells a story. For ei³’s new Secure Connectivity Trio, those stories reflect the three realities of modern manufacturing: building new, expanding fast, and securing what already exists.
Unveiled during private meetings and launch celebrations at last month at Pack Expo Las Vegas 2025 - Amphion, Zethus, and Portara embody the next chapter in secure industrial connectivity. Each represents a different way to connect, yet together they form one seamless, secure path forward.
AMPHION
The Builder
Our hardware gateway takes its name from Amphion, the mythical king who built the unbreakable walls of Thebes not with his hands, but with his lyre. As he played, the stones moved into place on their own, drawn by harmony and order.
It’s a fitting image for what Amphion does at the edge: orchestrating data flow, aligning connections, and creating an impenetrable digital foundation for every new machine, line, or plant.
Amphion builds. Where secure connection begins.
ZETHUS
The Architect
Amphion’s twin brother, Zethus, was the builder of form and function - the architect who turned strength into structure.
Our virtual gateway channels that same spirit, bringing Amphion’s trusted architecture into software form. Lightweight and containerized, Zethus installs directly on your existing controls with no new hardware or extra footprint required.
It’s the twin that scales, expanding your secure edge across machines, lines, and regions at the speed of software.
Zethus scales. The same security, multiplied.
Portara
The Portal
The final gateway, Portara, bridges the past and the future.
Its name comes from the monumental stone gateway that still stands on the island of Naxos—a doorway to a temple that was never completed, yet remains a timeless symbol of transition.
Like its namesake, Portara connects what was with what can be. It modernizes existing remote access systems, wrapping legacy infrastructure in Zero Trust security and unifying it into a single, managed network.
Portara transforms. The bridge between legacy and longevity.
Three Names, One Mission
Together, Amphion, Zethus, and Portara trace the full arc of manufacturing connectivity—from foundation to expansion to transformation.
Each runs on ei³’s Cyber-Physical System (CPS) Protection Platform, proven in 190,000+ connected machines worldwide with zero exploits in 25 years.
Three gateways. One shared purpose: giving manufacturers the power to stay secure while they grow.
