Centralized threat monitoring has improved visibility but demands complex setup and configuration
The best features Security Onion offers include acting as the intrusion detection system in my organization and helping me to address traffic, logs, and events happening within the organization. Since Security Onion is an open-source system that integrates with tools like Suricata and Zeek with the ELK stack, it enables threat detection and response capabilities, delivering high-level security measures at a cost, making it suitable for businesses of varying skill levels. These integrations with Suricata and Zeek have greatly impacted our workflow and our team's effectiveness by helping us address issues such as identifying intrusions, evaluating threats, and overseeing log files. This tool is very cost-effective, making it suitable for any size of organization wanting to use it.

Can be used to monitor a specific log or do specific actions, but its initial setup is not so easy
I have some customers using SolarWinds Log Analyzer to put some conditions on monitoring information from Windows servers and Linux servers. They use SolarWinds Log Analyzer to see if these conditions appear, and if they appear, generate a notification so that they can investigate what happened…
