On FortiMail, run `get system status` or use **Dashboard > Status**. Record the complete version; a lower build number can belong to a newer major release. [Firmware guide](https://docs.fortinet.com/document/fortimail/latest/administration-guide/432207/installing-firmware).\n- Apply the vendor's branch-specific fixes:\n\n| Product | Affected versions | Vendor solution |\n| --- | --- | --- |\n| FortiMail 8.0 | 8.0.0 through 8.0.1 | 8.0.2 or above |\n| FortiMail 7.6 | 7.6.0 through 7.6.6 | 7.6.7 or above |\n| FortiMail 7.4 | 7.4.0 through 7.4.8 | 7.4.9 or above |\n| FortiMail 7.2 | 7.2.0 through 7.2.9 | Upgrade to branch 7.4 or above |\n| FortiSIEM 7.5 | 7.5.0 | 7.5.1 or above |\n\nFor a FortiMail branch migration, select a corrected destination build from the table; the instruction to migrate does not make every build in the destination branch safe. Fortinet lists FortiSIEM 7.6 and FortiSIEM Cloud as unaffected. [FortiMail PSIRT](https://fortiguard.fortinet.com/psirt/FG-IR-26-175), [FortiSIEM PSIRT](https://fortiguard.fortinet.com/psirt/FG-IR-26-180).\n\n- If immediate FortiMail upgrading is impossible, disable IBE through **Encryption > IBE > IBE Service**, or use the documented CLI sequence:\n\n```text\nconfig system encryption ibe\n    set status disable\nend\n```\n\n  Account for interruption of that encryption service. Fortinet alternatively permits disabling internet access to webmail or restricting it to trusted private networks. For FortiSIEM, restrict access to TCP 27918 as specified in its advisory.\n- Hunt in FortiMail system-event and encryption logs using the current PSIRT indicators. Correlate unexpected `archive234` account creation and the message `User admin logged out from (null).` with other activity. Preserve suspicious logs and escalate for investigation; an indicator list is not a complete integrity assessment.\n- Harden administrative access separately. Fortinet recommends avoiding administration on the external interface and limiting administrator access to trusted hosts, with secure protocols and multifactor authentication when remote management is necessary. Check every administrator's permitted source networks. [Hardening guide](https://docs.fortinet.com/document/fortimail/7.6.0/administration-guide/472377/general-security-tuning).\n- After FortiMail upgrading, rerun `get system status`, confirm configuration conversion preserved the intended settings, and update FortiGuard packages. The firmware guide notes that installation supplies package versions bundled with the image, so newer detection updates may still be needed. Record a separate incident-response decision if compromise is suspected.\n- On FortiSIEM, check **Cloud health** and **Collector health** in the GUI for installed versions, running processes and resource usage. After upgrading, verify receipt of events from collectors and agents, plus recent incidents and their triggering events. Escalate failed checks to support. These are operational health checks, not proof of no compromise.
