Senserva Watch: we follow your CVEs and patches, along with leading security news so you do not have to
You found this site chasing a CVE or a KB. Senserva Watch is the free membership that chases them for you: one email when something you watch changes, and the Patch Tuesday wire on release day.
Senserva runs one of the largest free Microsoft security destinations on the web: live patch and CVE trackers, the hot ranking, and more than 10,000 per-CVE and per-KB reference pages, refreshed twice a day. Membership puts that engine to work for you personally. It is also how you get the most from Siemserva by Senserva, our audit product, with a fresh free audit credit every quarter.
What membership carries. Join Senserva Watch and get Three Free Unlimited Audits, a fresh audit credit every quarter, patch and security alerts on what you follow, 20% off when you buy, and, when available, the beta of Mark Shavlik's new patch scanner, 25 years after HfNetChk. The alerts are the daily half of that: an email when a CVE or KB you follow actually changes, the moment something you track is added to the CISA Known Exploited Vulnerabilities catalog, an EPSS jump or a new update that supersedes yours, and the Patch Tuesday wire on release day. A family of Senserva Watcher applications is coming: the same tracked data working inside the tools you already run. Members are first in line, and get the applications free. One email address. No tenant connection, no agent, no call.

- The audits
- Senserva Watch members start with Three Free Unlimited Audits and earn a fresh audit credit every quarter: one full run of everything Siemserva does, all users, all settings, all patches, all tenants. Each audit comes with the complete Senserva MCP server for Claude, so you can ask your own questions of the results, and with validated AI remediation that proposes the fix for what it finds and shows its working.
- A standing discount
- Members also get 20% off when they buy. Membership is free and stays free; the discount is there because members are the people who already know what we do.
- The alerts
- Patch and security alerts on what you follow, the Patch Tuesday wire on release day, and a message when something you track enters the CISA Known Exploited Vulnerabilities catalog, which is the change that actually alters your week.
- The patch scanner beta
- Membership includes the beta of the new patch scanner from Mark Shavlik, 25 years after he created HfNetChk, when it becomes available. It goes after the hard ones: the missing updates Intune and the other tools do not find. Local patching comes first, then the rest of the Senserva Watcher family as each one ships, the GitHub and Azure auditors among them, members first in line. Read the Shavlik story for where it comes from.
- Watch any CVE or KB
- Follow the updates and vulnerabilities that matter to your estate; we record what moved and when, and tell you when it does.
- Exports and a member API key
- Bulk exports and programmatic access to the member endpoints, as they roll out.
