SD-WAN & SASE · head-to-head
Cisco vs Fortinet
WAN-edge appliances and on-prem single-vendor SASE. Counts are scoped to this segment and the selected published-date window. Cisco carries 4.3× the disclosed CVE volume of Fortinet. Volume reflects disclosure practice and install base as much as code quality — read it with the severity mix. Sourced from the NIST NVD; lower counts indicate a smaller disclosed vulnerability surface — not necessarily lower risk.
