Security Onion
Security Onion is a free and open Linux distribution for threat hunting, enterprise security monitoring, and log management. The easy-to-use Setup wizard allows you to build an army of distributed sensors for your enterprise in minutes.

Graylog and Security Onion are both popular open-source solutions, but they have different focuses and capabilities in the realm of cybersecurity and network monitoring. Graylog is a centralized log management platform designed for collecting, processing, and analyzing log data from various sources. It excels at log aggregation and visualization, making it a valuable tool for IT operations and application troubleshooting. However, Graylog's primary focus is on log management and analysis, and while it can provide some security-related insights, it may lack some of the advanced security features offered by dedicated security-focused solutions.

On the other hand, Security Onion is a full-fledged network security monitoring (NSM) platform that incorporates several security tools and applications to provide comprehensive network security analysis. It includes tools like Snort and Suricata for intrusion detection, Zeek (formerly known as Bro) for network traffic analysis, and OSSEC for host-based intrusion detection. Security Onion is specifically tailored to detect and respond to security threats, making it a more robust choice for organizations looking to establish a comprehensive security monitoring and incident response system.

Another crucial difference between Graylog and Security Onion is their architecture and deployment. Graylog is typically deployed as a centralized server, and log data from various sources is sent to it for processing and analysis. It's more suitable for environments where log management is the primary concern. On the other hand, Security Onion is designed as a network security monitoring platform and is usually deployed as a network sensor, capturing and analyzing network traffic in real-time. This architecture enables Security Onion to provide more in-depth network security insights and threat detection capabilities.
