About the Daily Brief

Each weekday around 6am ET, the Daily Brief covers what changed since the last edition, in four sections: every addition to CISA’s Known Exploited Vulnerabilities catalog, other vulnerabilities and patches, breaches and campaigns, and analysis worth reading.

Nothing is ranked. Each section runs A to Z, so you can find what you run, and urgency shows as facts: labels like Exploited, and CISA’s due date on each KEV addition.

Each edition can be read in under five minutes.

Austin Simas is the editor. Every item is reviewed and edited by Austin before it publishes, and Austin is responsible for everything published here.
