Options from here

The Fortinet FortiWeb 400E is still supported. Options to plan around, in rough priority:

Monitor the timeline

Supported for now — track the end-of-service date and revisit at refresh planning.

Plan the refresh

Fold the eventual replacement into your multi-year budget.

Keep firmware current

Stay on a supported software train while under OEM support.

Third-party maintenance later

An option to extend life once the OEM cutoff nears.

Independent and informational — EOSL.ai sells no hardware or maintenance and lists no paid placements. Third-party maintenance keeps unsupported gear in production past the OEM cutoff; whether it fits depends on the asset's role.
