CRITICAL SYSTEMS SHIELD

Secure and Crypto-Agile Modernization for Legacy Mainframes

Financial institutions and insurance companies continue to rely on COBOL and z/OS mainframe systems to execute the vast majority of their critical transactions and high-value processes. While these environments have offered proven stability for decades, they face mounting pressures: rising maintenance and MIPS costs, a shortage of specialized talent, increasingly strict regulatory requirements (DORA, NIS2, PCI-DSS), and the critical need to implement Zero-Trust architectures.

SilicoTrust presents Critical Systems Shield, a pragmatic and incremental solution that allows you to modernize and secure these environments without incurring the high risks of a full migration ("rip & replace").

OUR SOLUTION

Integrated Hardware Trust & Rust Execution

01 / OFFLOADING

Secure Offloading with Rust

Selective and low-risk migration of batch processes, validations, and business logic calculations to Rust using proven tools like Ironclad. We maintain functional parity while significantly reducing MIPS consumption (typically 20-40% on migrated components).

02 / HARDWARE TRUST

Post-Quantum Protection Layer

Implementation of our patent-pending hardware-rooted ephemeral cryptography (based on STM32L5). We generate short-lived keys for Zero-Trust authentication between the mainframe and modern or cloud systems. Includes post-quantum signature verification with Dilithium (ML-DSA) and compatibility with IBM Crypto Express HSM.

03 / AUDIT & SECURITY

Continuous Security & Compliance

Specialized legacy audit, penetration testing, and continuous crypto-agility support.
