Lumen selects Atos for multi-year mainframe modernization

Plano, United States – January 9, 2024 – Atos, a global leader in digital transformation, today announces that it has been selected by global telecommunications company, Lumen, to modernize its mainframe services in a multi-year deal.

We look forward to deepening the relationship and creating opportunities to extend our collaboration in the future.”
