Zscaler and Schwarz Digits launched a sovereign cloud security offering for European customers, combining Zscaler‘s Zero Trust Exchange platform with Schwarz Digits‘ STACKIT cloud infrastructure in Germany.
The companies said the joint service provides Zero Trust Secure Access Service Edge, or SASE, from German data centers operated by STACKIT. The offering is aimed at customers across Europe, with a particular focus on public administration, defense, financial services and healthcare.
Sovereignty Moves Into Security Architecture
The announcement reflects a growing enterprise requirement in Europe: security platforms must address cyber risk while also satisfying data residency, operational resilience and supply-chain control demands.
Zscaler and Schwarz Digits said the service is intended to help organizations meet requirements tied to European regulations such as NIS2, DORA and the AI Act. The companies are positioning the platform as a way to protect hybrid workforces while keeping customer data and operations aligned with European legal requirements.
For security leaders, that makes sovereign cloud security less of a hosting preference and more of an architectural constraint. Organizations want cloud-delivered security capabilities, but many also need assurance about where data is processed and who operates the infrastructure.
Zero Trust Delivered From STACKIT
The joint service deploys Zscaler‘s security platform inside Schwarz Digits data centers. Zscaler said its Zero Trust Exchange is used by large enterprises, critical infrastructure organizations and government agencies to secure users, applications, data, devices and branches.
Schwarz Digits brings STACKIT, its sovereign cloud infrastructure, along with operational support for the European-hosted service. The companies said the offering covers deployment, management, operation and support of the cybersecurity cloud platform.
Christian Muller, CEO of Schwarz Digits, said technological independence begins with infrastructure. Zscaler Chief Reliability Officer Misha Kuperman said the partnership is intended to help customers reduce attack surface and prevent lateral movement while maintaining EU data residency.
AI Threats Add Pressure
The companies framed the announcement against a faster threat environment shaped by AI-driven attacks. They said European customers are asking for sovereign technology at the same time that cyber threats are increasing in scale, speed and sophistication.
That combination is likely to matter for regulated industries. Public agencies, banks, healthcare providers and defense organizations may need more control over security infrastructure as attackers automate reconnaissance, phishing, credential attacks and lateral movement.
The Bottom Line
The Zscaler–Schwarz Digits partnership gives European enterprises a sovereign cloud security option that keeps SASE and zero-trust enforcement closer to regional infrastructure requirements. The practical value will depend on whether customers can get cloud security performance and operational simplicity without giving up data residency and sovereignty controls.
