Short briefings from the people doing the work.

The Perimeter Brief is our running collection of short videos on the threats and decisions security leaders are dealing with right now. The format is intentional. Most of what's published about cybersecurity is either too high level to be useful or too technical to be shared past the SOC. The Perimeter Brief sits in between.

Each video is a few minutes long and built around something real. A vulnerability we've exploited in the field. A pattern we keep seeing on engagements. A decision a client wrestled with and what we recommended. The goal is to give you something you can use, whether that's a question to raise with your team, a control to revisit, or just a sharper way to think about a problem you've been working on.

New briefings publish regularly. Watch what's below, or subscribe to get them in your inbox.
