The Central Seal Infrastructure (ZESI) is a centralized system for the creation and management of electronic seals within organizations. It enables documents, data sets, or automated processes to be sealed electronically using organization‑bound certificates. ZESI is designed for environments where seals are applied in large volumes or fully automated workflows, without manual interaction by individual users. The system ensures integrity, authenticity, and traceability of sealed content while supporting consistent governance, access control, and compliance across multiple applications and departments.

Key Features

Central Seal Management Controls sealing operations from a single system.
