How priority is set

Four tiers with published rules, the same rules the Patchblox Vulnerability Hub uses. A fix takes the highest tier of any CVE it closes.

Patch now

Exploited in the wild: the vendor reports exploitation, or the CVE is in CISA's Known Exploited Vulnerabilities catalog.

Urgent

The vendor rates exploitation as more likely, or rates the CVE Critical.

High

CVSS 7.0 or higher, or rated High by the vendor when no CVSS score is published.

Routine

Everything else. Still worth installing on your normal schedule.

EPSS is shown as context and breaks ties within a tier. It does not move a CVE between tiers: a probability model should not outrank a confirmed exploitation report.

Where the data comes from

Microsoft Security Response CenterCVEs, KBs, affected products, exploitation and disclosure status
CISA Known Exploited VulnerabilitiesDate added, remediation due date, known ransomware use
FIRST EPSSExploit prediction scores and percentiles. EPSS data provided by FIRST.org
Apple security releasesmacOS updates, components and actively exploited flags
Linux distribution advisoriesDebian, Ubuntu, Red Hat and Fedora fixed package versions
Patchblox catalogWindows and macOS application versions and the CVEs each version fixes

This list is everyone's. Yours is shorter.

The tracker tells you what's exploited and what fixes it. Patchblox tells you which of your machines are still exposed, on every platform, and deploys the fix on Windows and Linux.

Get a demoSee the platform
  • Works from the Intune, Entra and Azure Update Manager data you already have
  • Matches every installed app and OS build to the fix that closes its CVEs
  • Deploys through rings with validation, then confirms the exposure closed
