Patch and vulnerability tracker

CVEs tracked.

A free, daily-refreshed dashboard of patch and vulnerability data across Microsoft and open-source software, ranked by real-world exploitation (CISA KEV) and exploit probability (EPSS). Built for IT, Audit and security teams. Pick a tracker to drill in, or pull the feeds and JSON API.

Sourced from Microsoft MSRC, NVD, CISA KEV, FIRST.org EPSS, OSV.dev, VulnCheck KEV, and the ENISA EUVD (EU), with vendor PSIRT advisories for the fix. Refreshed daily.

The trackers

Each is a free, searchable, daily-refreshed view, ranked the same way: actively exploited (CISA KEV) first, then EPSS and CVSS.

Most-exploited vendors
Vendors with the most CVEs added to CISA KEV in the time frame, across Microsoft and the rest of the ecosystem. The red portion of each bar is the ransomware-linked share. Open the full non-Microsoft tracker.

Data sources

Every tracker is built from authoritative, public feeds, refreshed automatically. No login, no telemetry, no scan data.

Microsoft MSRCPatch Tuesday data: KB-to-CVE mappings, Microsoft severity, affected products, and exploitation status.
NVD (NIST)The U.S. National Vulnerability Database: CVE metadata, CVSS v3 scores and vectors, and CWE weakness types.
CISA KEVThe Known Exploited Vulnerabilities catalog: CVEs confirmed exploited in the wild, with ransomware association.
EPSS (FIRST.org)Exploit Prediction Scoring System: the probability a CVE is exploited within 30 days, used to rank every list.
OSV.devOpen-source package and fixed version for each CVE, aggregating GitHub Security Advisories, PyPA, RustSec, and other OSV-schema sources. Used under the Apache-2.0 license; advisory records are CC BY 4.0.
CIRCL CVE SearchCVSS fallback when NVD has no score yet, so newly disclosed CVEs still get a severity.
VulnCheck KEVA broader Known Exploited Vulnerabilities list than CISA KEV, surfaced as a "VulnCheck KEV" signal. Data courtesy of VulnCheck, used with attribution.
ENISA EUVDThe European Union Vulnerability Database (ENISA, under NIS2), surfaced as an "EU EUVD" signal. Courtesy of ENISA, used with attribution.
Vendor PSIRTsEach vendor's own security advisory (Cisco, Fortinet, Ivanti, Citrix, Adobe, Apple, VMware/Broadcom, and more), linked as the authoritative fix for non-Microsoft, non-open-source products.
Attribution. Exploitation data labeled VulnCheck KEV is provided by VulnCheck and is used with attribution per VulnCheck's terms. EU cross-references are from the ENISA EU Vulnerability Database (EUVD). Open-source package fixes are from OSV.dev. Vendor PSIRT advisories are linked, not redistributed. Senserva is not affiliated with or endorsed by these providers.

For EU teams: vulnerabilities are cross-referenced to the ENISA EU Vulnerability Database (EUVD), the EU's official database under the NIS2 directive.

Feeds and API
How it is built

The feeds are pulled and rebuilt daily, then ranked: actively exploited (CISA KEV) first, then EPSS exploit probability and CVSS severity. Every KB and CVE gets its own linkable, cross-referenced page. Static and fast, with no account required.

From your own estate

These trackers cover the public picture. Senserva ranks the same data against the patches and CVEs actually present across your Microsoft 365, Intune, Defender, and Entra ID estate.
