    Automated Investigation & Response

    From detection to response without manual handoffs

    Stellar Cyber automates the investigation workflow — enriching incidents with threat intelligence, mapping to MITRE ATT&CK, and triggering response actions across connected tools. Analysts work confirmed, contextualized cases rather than raw alerts.
