Revolutionizing Enterprise Network Security

Close-up of the logo for Xiid, featuring dark blue text on a white background.

Xiid exists to challenge the status quo and redefine what security should be. Not reactive. Not an illusion. Not complex.

We're giving the industry a fundamentally new approach to securing networks—one that's built to stop attacks before they start.

Xiid was founded in 2018 on a single conviction: detection-based security was structurally broken, and the only real fix was to build something fundamentally different. That meant starting from first principles. Instead of just improving existing tools, we focused on rearchitecting how networks protect themselves.

Founders and early engineers developed the core architecture and intellectual property before evolving into what is now the Terniion platform. Series Seed financing closed in September 2021, marking the shift from foundational development to commercialization.

What followed was accelerated: platform maturation; enterprise deployments; DoD Authority to Operate achieved; further validation by the U.S. Air Force Research Laboratory, and expansion of use cases leveraging our patented technology.

In 2025, we expanded to enterprise environments and strategic partnerships.

The timeline reflects a deliberate choice: build the right foundation before scaling the business."
