For our day-to-day use cases, the correlation and attribution of different alerts are valuable. It is sort of an SIEM, but it is intelligent enough to run the queries and intentionally detect and prioritize attacks for you. At the end of the day, it is different data that you see. It correlates data for you and makes it meaningful. You can see that someone got an email and clicked a link. That link downloaded, for example, malware into the memory of the machine. From there, you can see that they started moving laterally to your environment. I quite like it because it gives visibility, so Workbench is what we use every day
