Today, 24 October, marks the Portuguese Army Day, a moment to honour the History, the people, and the mission of Exército Português.
For EID, it is also an opportunity to reaffirm our commitment to the Army’s evolution, standing side by side with those who safeguard national sovereignty and collective security.
Throughout this week, EID has been present in Viseu, until next Sunday, taking part in the Army Day celebrations that bring together military units, technology partners, industry players and institutions across the defence ecosystem. We are part of the exhibition “Rumo ao Futuro” organised by the Army.
Our exhibition showcases the latest TerraNex advanced communication systems designed to ensure secure, reliable, and interoperable connectivity in the most demanding operational environments.
Enabling mission success through technology
With over 40 years of experience, EID has established itself as one of the leading Portuguese defence technology companies, specialising in C4i systems (Communications, Command, Control, Computers and Intelligence).
Since 1983, and as part of Cohort plc since 2016, we have earned a reputation as a trusted partner to military and naval forces worldwide, developing solutions that combine engineering excellence, operational insight, and long-term reliability.
Our innovation roadmap is sustained by continuous research and development investment exceeding €2 million per year, focused on tactical and naval communication systems.
Recent developments such as the TerraNex TICS (Tactical Integrated Communication System), designed in close cooperation with the Portuguese Armed Forces demonstrate EID’s ability to deliver proven, scalable, and mission-ready technology.
This system, affectionately referred to – by the Chief of Staff of the Portuguese Army, General Eduardo Mendes Ferrão – as the “magic box”, is a symbol of how innovation directly enhances operational capability.
Trusted technology. Portuguese excellence.
From the OceaNex naval communication systems that empower maritime command and control to the TerraNex tactical solutions that connect dismounted soldiers and vehicles in real time, EID ensures seamless coordination across domains.
As we celebrate Army Day, we are reminded that technology serves people and that every innovation we deliver is ultimately built to strengthen the men and women who serve Portugal. Proudly “Made in Portugal”, trusted Worldwide, EID connects missions, empowering defence.
