Zero-Trust / ZTNA · head-to-head

Cisco vs Fortinet

Zero-trust network access: VPN-replacement gateways and ZTNA agents (on-prem footprint). Counts are scoped to this segment and the selected published-date window. Cisco carries 4.9× 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.
