Anyone know of a real SOC or SIEM that looks like this? Something that can be installed on-prem? Thanks.
It integrates an editor where you can convert query results to such visualizations. You could also integrate your custom viz made with JS libs (D3).
Entreprise Security is a Splunk paid app that provides a nice environment for SOC analysts.
Yes,you should give it a try, maybe through a docker image that will get you going quickly.
