Business Service Mapping
Business service mapping connects technical assets to the business services they support. This allows IT managers to move beyond device-level visibility and understand how infrastructure affects customer-facing applications and internal operations. By linking systems to business outcomes, teams can prioritize work based on service criticality. This improves incident response, risk management, and service-level decision-making.
Capabilities to support IT managers:
- Links infrastructure components to business services and processes
- Shows how technical issues may affect critical services
- Helps prioritize incidents based on business impact
- Supports service-level management, change planning, and risk assessment
Continuous Change Detection
Continuous change detection helps IT managers keep pace with constantly evolving infrastructure. As devices are added, cloud resources are provisioned, applications are updated, and configurations change, mapping tools detect and record those updates. This helps ensure infrastructure maps remain accurate without requiring manual maintenance. It also improves visibility into unauthorized changes, configuration drift, and historical activity.
Capabilities to support IT managers:
- Detects asset additions, removals, and configuration changes
- Updates infrastructure maps in near real time
- Helps identify unauthorized or unexpected modifications
- Maintains historical change records for troubleshooting and compliance
Configuration and Relationship Tracking
Configuration and relationship tracking gives IT managers detailed visibility into asset attributes and how systems are connected.
