JUST POSTED: We've just released an update to our Introduction to Security Onion overview video, recorded with Security Onion 3. Learn all about the platform, how it fits into your security architecture, the ways to pivot between logs from your network and your endpoints, and how it's all wrapped up in a lovely new interface. Alert investigation, detection engineering, ad hoc threat hunting -- Security Onion has everything you need to peel back the layers of your network and make the bad guys cry. https://youtu.be/xKWn_YlVOGo

Curious about the Human-Centered Investigative Playbook (HCIP) standard that underlies our Guided Analysis feature? If you're going to be at @bsidespgh@infosec.exchange this week, come see our Senior Engineer @blueteamgoon@infosec.exchange, presenting in the afternoon on that very topic. Hope to see you there!

HAPPY BIRTHDAY TO US! Today marks the twelfth birthday of Security Onion Solutions -- a dozen years of providing training, support, and other services on top of the free and open Security Onion platform. Here's to many more!
