Sophos ([email protected] CNA) via NVD
Sophos is its own CVE Numbering Authority. VulniPulse ingests Sophos's CVEs from the NVD CNA feed ([email protected]), each linking to its sophos.com advisory. Covers Sophos Firewall (XG/XGS, SFOS), Intercept X / Sophos Central endpoint, Sophos UTM, Sophos Mobile, Sophos Connect VPN and the Web/Email appliances — its firewalls are a repeated mass-exploitation target (the 'Pacific Rim' campaign), so an MSP-heavy, alert-hungry community.
