WatchGuard PSIRT Advisories via NVD
WatchGuard is not its own NVD CNA and its PSIRT portal has no machine-readable feed, so VulniPulse ingests WatchGuard's CVEs from NVD (keyword-filtered to WatchGuard, requiring a WatchGuard product in the description) and links each CVE back to the wgrd-psirt advisory when referenced. Covers Fireware OS on the Firebox firewall line, WatchGuard System Manager, the WatchGuard Agent / EPDR endpoint and AuthPoint MFA — SMB firewalls previously mass-exploited by the Cyclops Blink botnet, so a patch-now audience.
