Eviden launches its XMC Ethernet switch card, a cybersecure and sovereign solution for critical environments

Paris, France – June 12, 2025 – Eviden, the Atos Group product brand leading in advanced computing, cybersecurity products, mission-critical systems and vision AI today announces the availability of a cybersecure and sovereign Ethernet switching solution, the XMC¹ Ethernet switch card, specifically designed for mission-critical environments. This innovative solution uses a protocol break of communications to achieve the security and independence of critical communication systems.

Designed and manufactured in France, this XMC-format Ethernet switch card is a sovereign alternative to market offerings. It is produced at Eviden's Aix-en-Provence site in France by teams with expertise in mission-critical systems. It complements Eviden's range of MLS Gateway solutions, which are multi-level security gateways designed for two-way communications between networks of different classifications.

Eviden's new XMC Ethernet switch card is designed to protect data effectively. It incorporates powerful protection mechanisms that filter information, detect issues, and report anomalies to ensure secure and reliable transmission.

Coupled with the CPU card² of a critical system, Eviden's XMC Ethernet switch card is configurable, allowing systems to evolve. It offers the ability to partition data between open and secure environments that require a break in protocol for security and confidentiality reasons.

The card can be integrated on the mezzanine level with third-party embedded computers (air-land, naval or land-based) as well as with Eviden's multi-level gateway solutions (MLS Gateway).

Designed for the highest levels of criticality, Eviden's XMC Ethernet switch card supports multiple protocols³ and is compatible with the AFDX standard⁴, enabling seamless integration into existing avionics systems. It is also DO-254 DAL A certifiable⁵ and developed in accordance with standards that support certification to the CC EAL 4+ level⁶. It incorporates technology from Cetrac.io, a specialist in hardware switching technologies and a partner of Eviden.

Bernard Payer, Head of Mission-Critical Systems at Eviden, Atos Group, said: "Eviden's XMC Ethernet switch card is a fusion of technologies designed to guarantee the security and compartmentalization of critical information flows without reliance on foreign technologies or operators. Our next-generation Ethernet switching solution provides operators in mission-critical environments with a sovereign solution in their hands, reflecting the know-how of our teams. I am particularly proud to announce the availability of this solution.”

Eviden's XMC Ethernet switch card will be presented at SIAE, June 16-22, booth Avantix S3, GIFAS pavilion, hall 2B C140.
