Sopra Steria PSF Luxembourg & Evertrust strengthen digital trust

| minute read

This strategic partnership brings together a global integrator with a strong local presence across the European Union and a sovereign European PKI solution, helping organizations turn certificate management into a structured, automated, and resilient process in service of a digital trust foundation that is both sustainable and fully under their control. 

Sopra Steria PSF Luxembourg (a global integrator specialized in leading complex transformation and integration programs) and Evertrust (the European publisher of a PKI and certificate lifecycle management platform), today announced a strategic partnership aimed at addressing one of the most underestimated risks in cybersecurity: certificate and machine identity management. 

An Operational Risk That Is Too Often Overlooked 

An expired certificate should never bring down a critical service. Yet this type of incident remains common, and the consequences can be severe: service outages, revenue loss, reputational damage, or even exploitable security gaps. 

In today's hybrid and multi-cloud environments, this challenge is compounded by: 

· Limited visibility into the full inventory of active certificates and machine identities. 

· Fragmented ownership across infrastructure, security, and application teams. 

· A persistent risk of unplanned incidents, driven by the absence of automated renewal processes. 

As machine identities continue to multiply across cloud services, containers, APIs, and connected devices this risk keeps growing, even as certificate lifecycles grow shorter. 

A strategic digital sovereignty issue as well 

Beyond the operational risk, certificate and machine identity management raises a question that is becoming increasingly central for European organizations: control and sovereignty over their digital trust infrastructure. 

As regulatory requirements tighten (GDPR, NIS2, DORA, eIDAS 2) and dependence on non-European technologies comes under growing scrutiny, choosing a PKI solution that 

is sovereign, designed and operated in Europe is becoming a key differentiator for organizations seeking resilience and independence in their digital trust infrastructure. 

A Complementary Joint Offering 

This partnership brings together two complementary areas of expertise: 

  • Sopra Steria PSF Luxembourg, a global integrator contributes its expertise in leading large-scale transformation and integration programs, enabling enterprise-wide PKI deployments that account for each client's organizational, technical, and regulatory constraints. 
  • Evertrust, a European publisher, contributes its integrated PKI and certificate lifecycle management platform, providing centralized visibility, automated renewals, and a significant reduction in the risk of service disruption while ensuring full control of data and critical infrastructure. 

This alliance combines the scale and deployment capability of a global player with strong local roots in Luxembourg, with the technological independence of a sovereign solution — giving organizations both large-scale execution and complete control over their digital trust infrastructure. 

What clients can expect 

Together, Sopra Steria PSF Luxembourg and Evertrust help organizations assess their PKI maturity, deploy a centralized and automated certificate lifecycle platform, and build their digital trust infrastructure on a sovereign European solution fully compliant with EU regulatory requirements.



“This partnership with Evertrust addresses a strong need among our clients, who must now secure a growing number of machine identities without overburdening their teams, while relying on sovereign solutions. Our local presence allows us to support this transformation as closely as possible to teams on the ground” Jeremy Mazon, Country Manager, Sopra Steria PSF Luxembourg
