Situation in the cyberspace

The Information System Authority monitors and analyses what is happening in the Estonian cyberspace.

Every day, we provide an overview of daily automatic monitoring data and significant cyber incidents. We compile monthly summaries of the last month’s most important events and the situation in the Estonian cyberspace and the international environment.

Every week, we provide an overview of the most relevant security vulnerabilities of the past week on our blog.

Since 2013, we have been publishing a cyber security yearbook.
