What's in every issue

Questions about the Brief.

Want to see your own risks instead? Start free

Once a week. It is a weekly roundup, not a stream of alerts.

No. The Brief covers the threats everyone faces, so it is useful on its own. An account adds the part about you: your software, your domains and what is exposed online.

No. Platform alerts are about the software and domains you track, and arrive by email, in the app or by webhook as soon as we spot something that affects you. The Brief is a weekly summary of the wider picture.

The week's headline numbers, then the flaws newly confirmed as exploited, the ones attackers are hitting most or suddenly much more, exploited flaws not yet on the official lists, the biggest movers in likelihood of attack, what attackers are scanning for, trending malware, any supply-chain incidents, the week's security news and a short take on what it all means. Every item says what to do. It covers the wider picture, not your own organisation.

You get a shorter Brief. A section is left out when there is nothing worth saying, rather than padded.
