Support-lifecycle timing and source confidence only. Higher means more runway. It is not a risk, safety or compliance rating. How it is calculated
Listed in the CISA Known Exploited Vulnerabilities catalog
3 catalogued vulnerabilities are associated with this product line, 3 of them linked to known ransomware campaigns. CISA lists these as actively exploited.
CISA names product lines and software rather than part numbers, so each row states how it was matched. Confirm against the vendor advisory before acting: this augments vendor data, it does not replace it.

Options from here
The Fortinet FortiWeb 400E is still supported. Options to plan around, in rough priority:
Supported for now. Track the end-of-service date and revisit at refresh planning.
Fold the eventual replacement into your multi-year budget.
Stay on a supported software train while under OEM support.
An option to extend life once the OEM cutoff nears.
Independent and informational. EOSL.ai sells no hardware and no maintenance, and lists no paid placements. Third-party maintenance keeps unsupported gear in production past the OEM cutoff; whether it fits depends on the role the asset plays.
