About this source

CERT-Bund is the German federal cybersecurity agency's incident response team, run by the BSI. Their advisory feed publishes vulnerability disclosures and active exploitation warnings for software in widespread enterprise use: VPN appliances, email servers, file transfer products, ERP systems, browsers, hypervisors. Around 280 advisories a month, each with a CVSS score, affected versions, and remediation guidance. The advisories are written in German but cover the same vulnerabilities that show up in CISA, NCSC-UK, and JPCERT bulletins, often hours earlier. Watch this if you patch enterprise software, run a SOC, or write detection rules. GovPing publishes each advisory with the affected vendor, CVSS score, and original CERT-Bund link.
