ERT Rebrands as Entarian to Reflect Integrated Mission Solutions Platform

Transition follows Sev1Tech acquisition and strengthens delivery across national security architecture, satellite ground systems and federal modernization programs

GREENBELT, Md.--(BUSINESS WIRE)--ERT announced it will operate under a new corporate name, Entarian, reflecting the company’s evolution as an integrated mission solutions provider serving customers across space, defense and federal civilian agencies.

The name change follows the company’s recent acquisition of Sev1Tech and marks the next step in aligning engineering, digital modernization and enterprise capabilities under a unified platform supporting complex national missions. Sev1Tech will also operate under the Entarian name.

Entarian connects systems, models data and secures enterprise environments, strengthening customers’ ability to modernize infrastructure, improve operational resilience and support mission delivery in regulated environments.

The transition positions the company to support mission‑critical programs across the national security architecture, strengthen space and science missions through satellite ground systems, data integrity, and operational continuity, and deliver next‑generation federal digital modernization initiatives.

“This change reflects the kind of partner our customers need us to be—one that can connect engineering, data and secure enterprise capabilities to support missions that are becoming more complex, more integrated and more critical to high-stakes missions,” said Chief Executive Officer Mark Lee.

The company will transition to the Entarian name in the coming months as part of a phased rollout across customers, partners and employees.
