What it checks
Whether the OS release is end-of-life.
Why it matters
EOL means no more security patches — permanent exposure.
How to fix
Plan migration to a supported release.
InfraGuard runs all 36 checks across your servers at once and grades each host A–F.
Track these versions on your own servers
InfraGuard collects installed software versions from every server and flags the ones with known vulnerabilities. Self-hosted — nothing leaves your network.
