The story behind Amphion, Zethus, and Portara

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.

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.
