AV26-1081: Fortinet Hardening Release for FortiOS, FortiManager, FortiAnalyzer, FortiAuthenticator, FortiMail

The Cyber Centre published AV26-1081 on October 23, 2026 for a Fortinet security hardening release covering FortiOS 7.2 to 8.0, FortiManager, FortiAnalyzer, FortiAuthenticator and FortiMail, with fixed versions listed per branch and FortiMail 7.2 told to move to 7.4 or later. FortiGate firewalls sit at the edge of many Canadian utilities, municipalities and carriers, and this landed the same day as a published campaign against exposed Fortinet and Palo Alto appliances. Patch to the listed versions and confirm the management plane is not reachable from the internet.

Why this matters for your infrastructure

Every advance in quantum computing shortens the window for migrating long lived infrastructure off quantum-vulnerable encryption, and data captured today can be decrypted later. Fabric Networks helps energy, government, telecom and community networks move to quantum-safe encryption on their own timeline, not an adversary's.
