Which Generation of SIEM?

There are many SIEM solutions available. Some of those ML/AI tools available are using pure statistics for outlier detection apart from current hot topic ML, AI algorithms. What is tactical SIEM? if you are spending 80 percent of your time within a SIEM tool doing alert review and analysis, then you are on the right track. If you are an organization that is instead focusing heavily on collecting more data sources, applying patches, or running compliance reports, then your SIEM implementation may not be tactical. So correlation/alert is the heart of SIEM.
