Security Signal is in an active prototyping and conceptual validation phase. It works with simple probes, and can help you to verify that your SIEM (or outsourced SOC) is working properly. Simply trigger the probe and see how long it takes to record detection.
We are partnering with customers that want to help us test this capability and make it more effective. If you are interested in learning more about securitysignal.io, reach out at email@example.com.
