Information Security

The ProZorro public procurement system is based on the principles of open data, but we take the demands of the confidentiality, integrity and data availability very seriously. While the public purchasing tender information is available on the web portal free and without any registration, the integrity and security of the system are built into its data architecture. A number of measures are constantly undertaken and processes are put in place to guarantee information security, specifically to protect sensitive data from unauthorized access, to secure the integrity of the central database and to maintain open and unrestricted access to open data. The central database is hosted within secure cloud service De Novo that had been created to meet the strict information security requirements of the Data Protection Service of Ukraine for government data systems.
