Senserva Watch: we follow your CVEs and patches 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 Watch: follow the CVEs and patches you care about. We email you when they change. Free, just your email.

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 three times 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 gets you

Live today or rolling out next: each benefit is labeled honestly. Members get everything first, at the same price: free.

Watch any CVE or KB

A Watch button on every one of our 10,000+ CVE and KB pages. We email you when a watched item changes: a CISA KEV addition, an EPSS jump, a CVSS revision, or a new or superseding patch.

Rolling out to members first

The Patch Tuesday wire

The release-day email: official counts, the zero-days, the Senserva AI read, and links into our per-KB fix pages, sent when our refresh lands, hours before most coverage.

From the next Patch Tuesday

Product-line watches

Follow Windows Server, Exchange, Edge, or any Microsoft product line and get only its patches and CVEs each month, ranked by real-world exploitation.

Rolling out to members first

Bulk exports and a member API key

Every tracker already exports CSV and JSON. Members get the bulk downloads: full patch history, the joined KEV view, monthly archives, and a rate-limited API key for your own tooling.

Rolling out to members first

State of Microsoft patching, monthly

A members-only monthly report built from our private history warehouse: the risk trend, KEV velocity, time-to-exploit, and what actually got exploited. Shareable inside your org.

Rolling out to members first

A fresh audit credit every quarter

The standing free-audit offer becomes a member right: a new full Siemserva audit credit each quarter, so your posture check never goes stale.

Included with membership

Also ahead for members: early access to new trackers and site features, a say in what we build next, and advanced third-party threat intelligence feeds in a later member tier. Everything on this page that is not live yet ships to members first, announced on the wire.

The member audit, every quarter

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.
