Did the Zero to Zeek course with Chris Brenton. Network visibility is huge, and Zeek is pretty much the standard for doing it right. Learned how to deploy and configure Zeek as a network sensor. We went from raw packet captures to generating structured logs that you can actually search and analyze. Also got into writing basic Zeek scripts to customize what gets logged. Being able to see exactly what is happening on the wire is a critical skill for any network defender.
