Riigi Infosüsteemi Amet, better known as the Information System Authority (RIA), is Estonia’s state agency for digital government and cybersecurity. Based in Tallinn, it operates under the Estonian government and plays a central role in maintaining the country’s digital state infrastructure. Its remit covers the security and operation of key national information systems, oversight of cybersecurity, and support for public digital services used by citizens, businesses, and government bodies.
RIA’s work sits at the intersection of e-government and cyber defence. On its website, the agency highlights services and guidance for preventing fraud, reporting cyber incidents, and managing vulnerabilities. It also publishes analyses of cyber incidents and security trends, and provides practical information for users and organisations through portals such as itvaatlik.ee, id.ee, and the national e-service ecosystem. The agency is also involved in supervision and regulatory decisions related to cybersecurity and information security standards.
A notable part of RIA’s activity is the maintenance and development of Estonia’s digital identity and interoperability infrastructure. Its public-facing material references the development of the European Digital Identity Wallet service in Estonia, as well as the country’s ID software and related authentication services. RIA is also associated with X-Road, the data exchange layer that enables secure communication between public and private sector systems in Estonia and beyond. Its GitHub documentation presence underlines its technical role in maintaining and explaining that infrastructure.
RIA’s geographic scope is primarily national, but its work has wider European relevance because Estonia’s digital identity and interoperability models are often referenced across the EU.
