PULSAR captures the signal. ASTRAL holds the baseline. AURORA makes sense of both.
All three tools are independently useful and progressively more powerful in combination.

AURORA

PULSAR
Platform for Unified Log Search, Alerting & Review. Free, open-source M365 audit log ingestion with indefinite retention and AI-ready query interface.
