Windows Server 2022 ↗
Summary iPlain-English security verdict for Windows Server 2022, generated from its current health score, actively-exploited vulnerabilities, and latest supported version.
Windows Server 2022 currently scores 85/100 — good. 85 actively-exploited vulnerabilities (CISA KEV) affect older releases (e.g. CVE-2023-44487) — staying on the latest supported version keeps you clear of them. The latest supported release is 10.0.26100. It's largely safe; apply minor updates as they appear. Note: this product is assessed at the product level on recent (365-day) activity rather than an exact per-version match, so it is never marked a confident "healthy".
Disclosure trend iNew CVEs published for Windows Server 2022 each year (NVD). A higher bar means more disclosures that year — more scrutiny, not necessarily less safe.
⚠ 25 of its known vulnerabilities are linked to ransomware campaigns (CISA KEV).
Patch priority — what to act on iThe issues to fix first — actively exploited (CISA KEV) first, then by exploitation probability (EPSS), then severity. Each row's "→ fixed in" is the earliest version that patches it; "see advisory" means no fixed version is published.
Most urgent first — actively exploited, then likeliest to be exploited.
