Our purpose
Certus Ledger Plc is building systems that help businesses move beyond simple digital signatures and toward verifiable execution: who acted, when they acted, which document version was used, what evidence was captured, and where the final record is stored.
Our portfolio
Certus Ledger is the corporate home of SignumEra and Prodicium, supported by the Certus Ledger Signing Spine — a shared foundation for verified identity, document integrity, signing policy, evidence packages and final records.
