Cloud Temple all'User Experience Day 2026

We’re delighted to take the stage at UX Day 2026, contributing both a morning keynote and an afternoon workshop on one of the defining topics for European IT leaders today: building a credible, high-performance sovereign digital stack.

Morning Keynote

Beyond the Cloud Promise: How Europe is quietly building its sovereign digital stack

Speakers : Christophe Lesur (CEO, Cloud Temple), Sébastien Lescop (CEO, Cloud Temple), Benjamin Schilz (CEO, Wire)

Two years ago, sovereign IT was a topic for compliance officers. Today, it lands on the CEO’s desk. The reasons are well known : tightening regulation, shifting geopolitics, the unresolved status of EU–US data flows, and the growing realisation that critical operations cannot depend on foreign jurisdictions. But beyond the talk, a real European sovereign stack is being built and it works at scale.

In this keynote, the CEOs of Wire and Cloud Temple share what is happening behind the scenes. Wire, the secure collaboration platform trusted by the German Federal Government, the BSI, the German Ministry of Defense, BMW and the Schwarz Group, and Cloud Temple, one of Europe’s most certified sovereign cloud operators, will show how a software platform and a sovereign infrastructure combine to form a credible, high-performance alternative to US suites for organisations that cannot afford to lose control over their most strategic data.

Grounded in real customer cases across industry, public sector, banking and media, the session gives participants a clear view of:

• Where sovereign IT actually delivers value today (and where it does not)
• How leading European organisations are structuring the conversation internally
• What the next 18 months will bring on the regulatory and technological fronts

Afternoon Workshop

The Sovereign Cloud Playbook: 3 practical steps to isolate and secure your critical workloads

Speaker: Alexandru Lata, CPIO, Cloud Temple

A hands-on, intimate masterclass for IT leaders dealing with the “Innovation vs. Sovereignty” dilemma. You don’t have to migrate everything out of AWS or Azure. In this session, we share a pragmatic playbook for building a highly secure, sovereign “clean room” for your most critical data and AI workloads, while maintaining interoperability with your existing public clouds.

We’ll walk through:

1. Data Triage : how to quickly identify workloads requiring absolute legal immunity
2. Hybrid Architecture : how to seamlessly connect a SecNumCloud / EUCS-High sovereign zone to your current IT landscape
3. The “Trust-by-Design” Checklist : the real technical safeguards (encryption, confidential computing) and contractual safeguards that make sovereignty enforceable in practice

Join us at User Experience Day 2026 to hear directly from our speakers and see how sovereignty and innovation can work together.
