@PallaviSin31974 Thanks for mentioning Security Onion!

Best thing I did for my cybersecurity career: stopped waiting for a job to give me experience and started building my own labs. Splunk, ELK, Security Onion, AWS, Azure. All are free or cheap to set up. No excuses. #Cybersecurity #BlueTeam #SOC

ICYMI Security Onion 3.0 is coming soon! Are you ready?

@infinit3i Stenographer is no longer maintained so we have no choice but to remove it. But there are some additional benefits. Removing steno saves some CPU cycles and using Suricata for full packet capture results in normal pcap files that can be processed by any standard libpcap tool.

@securityonion What is the reason to remove stenographer?

@Godfather_OBW Thanks, you're gonna love it!

@securityonion The team at Security Onion do fantastic work, I'm very excited to see what 3.0 and beyond hold for SO!
