Zyxel Security Advisories via NVD

Zyxel runs its own CNA (security@zyxel.com.tw), but a large share of Zyxel CVEs are assigned by MITRE and third-party researchers — so VulniPulse ingests them from NVD by keyword (which covers more than the CNA feed alone), requiring a Zyxel product in the description, and links back to the zyxel.com security advisory when referenced. Covers the USG FLEX / ATP / VPN firewalls, Nebula-managed access points, the GS-series switches and the VMG/EMG gateways — an SMB fleet that is a chronic KEV / actively-exploited target.
