Expertise

Modernization capabilities

We help large organizations and government agencies modernize their critical systems while maintaining reliability, security, and compliance.

Legacy system modernization

Mainframe-to-Linux migration with no rewrite. We adapt COBOL compilers to support proprietary dialects (Bull GCOS, IBM, MicroFocus) and preserve decades of critical business logic.

COBOL transformation

Support for 20+ COBOL dialects. SuperBOL Studio brings a modern environment (VSCode, LSP, CI/CD) without replacing what you already run, and removes any dependency on IBM and MicroFocus licenses.

Critical infrastructure security

We secure critical financial and public administration systems with formal methods and certification processes, from restricted distribution up to EAL6+.

Regulatory compliance

We support companies through their certification processes and cybersecurity challenges: DORA, NIS2, restricted-distribution accreditation, Common Criteria.

Enterprise integration

Seamlessly integrate legacy and modern systems across your organization, enabling digital transformation without disruption.

Flagship tool

SuperBOL: the sovereign COBOL suite

The open-source GnuCOBOL compiler and SuperBOL Studio in a single suite. Support for 20+ dialects (IBM, MicroFocus, Bull GCOS), native DevOps integration and cloud deployment, without replacing a single line of existing code.

20+ COBOL DialectsOpen SourceDigital Sovereignty

In production at DGFiP (40.7 million taxpayers), Baader, Bethmann and ODDO BHF.

Use case

Mlang & Catala: French tax computation

40.7 million taxpayers, 37 million declarations a year. Mlang, the compiler for the M language created by the DGFiP in the 1990s, is still in production. Catala, born at Inria, takes the approach further with formal semantics. We have contributed to its development.
