Hurricane Helene Update
On Friday, September 27, Hurricane Helene hit Augusta GA. All of our team members are safe, but many folks had significant property damage and were without power and Internet access for several days. Due to the amount of damage to the Augusta region, we had no choice but to cancel all Augusta Cyber Week activities including our 4-day Security Onion training class, our annual Security Onion Conference, and BSidesAugusta.
We are truly thankful for the countless men and women who have worked tirelessly over the last week to restore power and other services to our area. At this point, most of our team members have power although some still do not have reliable Internet access. We are all starting the long process of slowly repairing the property damage that this brutal storm caused.
We sincerely appreciate all those who reached out to check on us. Several folks have asked how they can help support Security Onion Solutions during this time. For individuals, please consider donating to the Red Cross to help others in need. If your organization would like to help support Security Onion Solutions directly, please consider purchasing Security Onion Pro. Thank you!

About Security Onion
Security Onion is a free and open platform built by defenders for defenders. It includes network visibility, host visibility, intrusion detection honeypots, log management, and case management.
For network visibility, we offer signature based detection via Suricata, rich protocol metadata and file extraction using your choice of either Zeek or Suricata, full packet capture, and file analysis. For host visibility, we offer the Elastic Agent which provides data collection, live queries via osquery, and centralized management using Elastic Fleet. Intrusion detection honeypots based on OpenCanary can be added to your deployment for even more enterprise visibility. All of these logs flow into Elasticsearch and we’ve built our own user interfaces for alerts, dashboards, threat hunting, case management, and grid management.
Security Onion has been downloaded over 2 million times and is being used by security teams around the world to monitor and defend their enterprises. Our easy-to-use Setup wizard allows you to build a distributed grid for your enterprise in minutes!
