Today, we are announcing that Security Onion 2.3 will reach EOL on April 6, 2024.

If you are a current Security Onion Solutions customer with Professional Services or Appliance coverage and have concerns about getting migrated by this date, reach out to Support and we’ll work with you. Keep in mind that CentOS 7 EOL is June 30, 2024.

If you would like to migrate your data from 2.3 to 2.4, you can find an overview of the process at https://docs.securityonion.net/en/2.4/appendix.html.
