Splunk
We make machine data accessible, usable and valuable to everyone—no matter where it comes from. You see servers and devices, apps and logs, traffic and clouds. We see data—everywhere. Splunk offers the leading platform for Operational Intelligence. It enables the curious to look closely at what others ignore—machine data—and find what others never see: insights that can help make your company more productive, profitable, competitive and secure.

Security Onion and Splunk are both security monitoring and threat detection solutions that offer network visibility and log analysis features. They provide dashboards for real-time monitoring, allow integration with other security tools and enable incident response through collected data.

But Security Onion (available since 2009) is an open-source SIEM software, targeted for small and medium-sized organizations and focuses on intrusion detection. It provides complete network traffic monitoring suite, including IDS/IPS tools like Suricata.

Splunk (2003) is commercial system for large enterprises originally designed for IT operations and log management. It offers advanced analytics and machine learning capabilities via its Splunk Enterprise Security app.
