Secure Remote Access / VPN · head-to-head
Cisco vs F5
SSL/IPsec VPN gateways and ZTNA appliances. Counts are scoped to this segment and the selected published-date window. Cisco carries 1.3× the disclosed CVE volume of F5. 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.
