    the entire organization   Get more value out of existing systems   Data aggregation is “hunter friendly”   Better organization around:   Detection platform coverage   Detection planning   General   Threat-specific   Prioritization of detection resources   Quicker, more accurate incident detection and response   Leverage your detection/response infra as an offensive capability Benefits of Enterprise Security Monitoring 6
