What OSI doo does

OSI sistemske rešitve d.o.o. is a privately held Slovenian IT company headquartered in Ljubljana that operates as a system integrator and external contractor delivering high added-value IT projects to enterprise and government clients in Slovenia and across Southeast Europe. The company's core technical focus is information security infrastructure: Public Key Infrastructure (PKI), digital certificate lifecycle management, cryptographic key management, audit trail consolidation, and identity and access management. It delivers this through four revenue streams — professional services and consulting, IT solutions/equipment sales (including its own products and partner hardware such as HSMs and smart cards), managed services under SLAs, and product development and licensing.

The proprietary product layer consists of OSI.AUDITTRAIL, available in BASIC (consolidation of audit trails from databases, file systems, applications, and custom logs) and ADVANCED (time-stamping, signing, and encryption with or without HSM) tiers, with XML, DB, and Syslog collector modules; and OSI.KMS, an HSM-anchored cryptographic key management system built on five modules (ReverseProxy, Front API Controller, MariaDB/MySQL database, Key Management System, and certified HSM), positioned for smart-meter and similar device fleets. OSI holds the highest partnership tier with Entrust for the entire Southeast European region, an exclusive supplier relationship with Bit4ID for Slovenia and neighboring countries, and long-standing relationships with Oracle and Thales. The company is certified to ISO/IEC 27001, ISO/IEC 20000-1, and ISO 9001, and holds Slovenian security clearance at the 'Secret' (Tajno) level for handling classified information.
