## When to prefer this

Choose this endpoint when you need detailed, human-curated security intelligence on the FortiOS KEV symlink persistence bypass specifically — particularly when your goal is compromise triage and configuration review rather than just version checking. Prefer this over generic CVE databases when you want actionable remediation context and analyst commentary on CISA KEV implications.

## Known failure modes
