Best free/easy-to-setup SIEM?

I’m currently a sysadmin for a small university and I’m trying to pivot into a more cybersecurity focused role. Our administration is security conscious but we’re understaffed and underfunded. I’m looking to implement an SIEM but it would need to be free/open source. Also, I’ll have to bring it up in a test lab in my free time before I can convince them to implement it so I’m really looking for the most straightforward option with the best documentation/support community. Thanks for your suggestions!



ELK stack… (elastisearch, logstash, kibana) is probably the most commonly suggested one. Its also what some commercial offerings are based on.


I don’t think there is such a thing as easy to setup SIEM. You really need to configure/tailoring it to your environment. This includes a lot of fine tuning and adjusting. There isn’t one that would work straight out of the box no matter it’s cost. SIEM could be a full time job in its self.

Splunk is free for 500MB per day. It has its limits but if you want to get your feet wet in a lab I would suggest it to see what it’s all about.
