The global community of Zeek users and developers gathered virtually last month, October 13-15, for the annual ZeekWeek (formerly BroCon) event. 

This year’s Zeek Week smashed multiple records: over 1400 network security professionals representing 300 organizations joined from over 70 countries to share ideas and knowledge.

This year’s virtual event consisted of two Zeek training sessions on Day 1; 13 defender, threat hunter and IR focused presentations on Day 2; and 10 developer focused presentations on Day 3.  Day 2 and 3 presentations were delivered in a fast-paced 20 minute format,discussions and questions handled via dedicated Slack channels. 

In case you missed this year’s event, here is a list of all the talks – as well as slides, plus links to videos and Slack channel discussions.
