Securosys adds integrated SAM functionality to Primus HSM for eIDAS remote signing

Securosys says its Primus HSM now includes integrated Signature Activation Module functionality for eIDAS-compliant remote signing architectures. The move is meant to simplify Qualified Signature Creation Device deployment for QTSPs and technology partners while reducing integration and certification overhead.

Why it matters: - Securosys is trying to remove a major technical hurdle in eIDAS remote signing by combining the cryptographic module and Signature Activation Module in one platform. - The approach could reduce integration work, certification effort and vendor dependence for qualified trust service providers. - The company is also positioning Primus HSM as a foundation for future remote signing requirements, including PQC-ready deployments.

What happened: - Securosys announced the availability of integrated SAM functionality within Primus HSM for eIDAS-compliant remote signing architectures. - The Zurich-based security vendor says the combined platform is designed for QTSPs and technology partners building qualified remote signing services. - The announcement was dated October 20, 2026.

The details: - Securosys says the integrated design places SAM functionality inside the tamper-protected boundary of Primus HSM. - The company says the setup removes the need for a separate SAM solution while preserving the security controls required for qualified remote signing. - Primus HSM is certified to meet the Cryptographic Module requirements in CEN EN 419 221-5 and the Signature Activation Module requirements in CEN EN 419 241-2. - Securosys says the architecture supports QSCD deployment from a single supplier. - The company says the platform is designed to preserve existing application integrations without major code changes. - Securosys says the unified approach provides a single HSM and SAM certification path. - The company says Primus HSM and CloudHSM serve as the cryptographic foundation for compliant remote signing infrastructures. - Securosys also says it works with QTSPs and solution providers that deliver complete end-user signing solutions. - More information is available at the company’s announcement.

Between the lines: - The announcement reflects a broader shift toward simplifying qualified remote signing stacks, which have traditionally relied on separate components from different vendors. - Securosys is emphasizing platform integration as a way to lower operational friction while keeping the security model aligned with eIDAS requirements. - The company is also signaling that its value proposition is infrastructure and cryptography, not the full end-user signing workflow.

What's next: - Securosys expects QTSPs and technology partners to use the integrated Primus HSM architecture as they build or expand remote signing services. - The company says the platform is designed to help customers prepare for future eIDAS-related requirements. - Securosys may lean on the integrated SAM capability as a differentiator in regulated digital trust markets.
