Security in 2026: what changed
A firewall and three identity appliances leave sale, and FortiOS 8.0 is out. Palo Alto Networks, Fortinet and Cisco security: supplied and integrated.
Four changes since December 2025 reach what a security quote can name. Your requirement should account for each.¹
Every date comes from the vendor's or publisher's own page. Third-party reports are marked.
