CESNET CyberFeed – Vulnerability Reports
This service is described in more detail at CESNET-CERTS.
The security services provided by CESNET are designed to provide significant support in ensuring the cybersecurity of connected organizations. Although we strive to provide quality and reliable services, it is not possible to guarantee absolute coverage of all security vulnerabilities. Our services should be seen as a complement to an organization's own security management, not as a replacement. The client bears ultimate responsibility for securing their environment.
