Toulouse, January 12 2026 : As 2026 starts, CYSEC is pleased to report on a year 2025 of significant progress in the commercial and technical deployment of ARCA Trusted OS. Throughout the past four quarters, our go-to-market strategy has focused on expanding the interoperability of our Confidential Computing solutions across sovereign, public, and private infrastructures.
The following four milestones represent the cornerstone of our achievements this year, reinforcing our commitment to verifiable digital sovereignty.
Q1: Implementation of End-to-End Attested Launch
In the first quarter of 2025, CYSEC successfully completed the development of an end-to-end attested launch solution on a customized hypervisor.
- Technical Significance: This protocol empowers VM owners to verify the integrity of the entire software stack at the moment of deployment. Within a Confidential Computing environment, this ensures that the execution context remains untampered and secure.
- The CYSEC Advantage: This capability is driven by a proprietary verification management system developed by CYSEC, providing a robust framework for cryptographic trust.
Q2: Integration into the Polo Strategico Nazionale (PSN)
A major commercial milestone was reached in Q2 2025 with the official inclusion of ARCA Trusted OS in the Polo Strategico Nazionale (PSN) catalog.
- Institutional Reach: This integration grants all PSN users direct access to CYSEC’s Confidential Computing suite, facilitating the adoption of high-security standards within the Italian public sector.
- Operational Scale: Since its inclusion, we have overseen the initial deployment of ARCA Trusted OS across large-scale clusters comprising several dozen confidential VMs, demonstrating the scalability and reliability of our architecture within the PSN framework.
Q3: Product-Ready Attestation for Microsoft Azure
During the third quarter, CYSEC released a product-ready version of its attested launch protocol for Azure Confidential VMs.
- Sovereignty in the Public Cloud: This release addresses a critical requirement for data sovereignty: it excludes the cloud provider from the chain of trust above the firmware level.
- User-Centric Verification: By hosting and operating the CYSEC Verification Manager locally, VM owners maintain exclusive control over the attestation report verification, ensuring that trust is not delegated to the infrastructure provider.
Q4: Support for VMware vSphere v9
Closing the year, CYSEC has extended its attested launch protocol to vSphere v9, providing a product-ready solution for virtualized enterprise environments.
- Consistent Security Posture: This integration mirrors our Azure solution by placing the verification of the attestation report directly in the hands of the VM owners.
- Hybrid Cloud Versatility: This achievement ensures that organizations utilizing vSphere can maintain the same rigorous security and attestation standards as those deployed in public cloud or sovereign environments.
Conclusion
The milestones achieved in 2025 solidify ARCA Trusted OS as a premier solution for verified Confidential Computing. By bridging the gap between diverse infrastructures—from the Italian Sovereign Cloud to global platforms like Azure and vSphere—CYSEC continues to set the standard for secure and autonomous digital operations.
