One system, four roles

Why it matters that Hal is one system

Four tools that each see a slice produce four partial answers and a person to reconcile them. One system that has read everything produces one answer.

That is not an architecture preference, it is the reason the alerts are worth reading. When a sign-in anomaly fires, the thing that decides whether it matters is context the SIEM does not have: whether that device is managed, whether there is an open ticket about it, whether the documentation says that user travels. Hal has all of it already, because the same system that watches the logs also read the RMM, the PSA and the documentation.

The same logs, the same context, the same Hal

The only thing that changes between the four roles is which question you are asking. There is no separate product to buy, no second console to learn, and no integration to maintain between them.
