What's AdvisoryWeek?
AdvisoryWeek is a once weekly email that rounds up the latest security advisories published in the past week.
- Can't find a way to get security emails from your favorite vendors? Not all vendors provide email notifications, you can use AdvisoryWeek to make sure you get important security advisories and bulletins.
- Security FOMO? Don't fret, AdvisoryWeek tracks security advisories from major vendors like Microsoft, Adobe, Apple, Oracle, and many more.
- Too much noise? AdvisoryWeek is one email per week, with organized links to each vendor security advisory.
