Zero-days under active attack, explained in plain English

Am I affected?

Pick a product and type the version you run. We check it against every flaw on CISA's list of vulnerabilities attackers have used, and tell you which ones affect you and which version fixes them.

Check this device

See whether the phone or browser you're using right now is missing a fix for a flaw attackers are using.

This reads only the version your browser already shares with every website. It runs on this page; nothing is sent to us or saved. It can't see your files or other apps.

Check any product

Find your version on the device's dashboard or the app's About screen. Version formats vary, so type it exactly as shown. For Windows, run winver and type the full build, like 10.0.22631.4460.

Based on the affected-version ranges vendors publish in the official CVE records. Records are sometimes incomplete or wrong, so when we can't tell, we say so. Always confirm with the vendor's advisory before relying on a result, especially a "not affected" one.
