Enterprise XDR Implementation Roadmap | Fidelis Security

1. Visibility and Data Health

• Percentage of priority assets covered
• Percentage of unmanaged assets discovered
• Network segments monitored
• Endpoint agent health
• Cloud accounts and subscriptions monitored
• Identity systems integrated
• Telemetry ingestion latency
• Data-source availability
• Event parsing and normalization failures
• Retention achieved by data class

Whether the XDR platform has complete, reliable, and timely evidence to support detection and investigation. 2. Detection

1. Mean time to detect
2. Detection rate for tested attack scenarios
3. ATT&CK coverage for prioritized techniques
4. Percentage of detections using multiple telemetry sources
5. High-confidence detection rate
6. False-positive and non-actionable alert rates
7. Percentage of incidents detected before material impact
8. Detection rule precision after tuning
9. Material coverage gaps identified and closed

Whether XDR is producing relevant, validated, and high-confidence detections. The number of enabled rules alone should not be treated as a maturity metric. 3. Investigation

1. Mean time to acknowledge
2. Mean time to determine scope
3. Mean time to reach an analyst decision
4. Number of tools used per investigation
5. Number of manual enrichment steps
6. Percentage of cases with complete evidence
7. Time spent reconstructing attack timelines
8. Analyst hours per incident
9. Percentage of investigations completed within SLA

Whether XDR is reducing investigation friction and helping analysts reach reliable decisions faster. Measure from the point at which the analyst begins working, not only from ticket creation. 4. Response

• Mean time to contain
• Percentage of incidents contained within target time
• Number of automated actions per incident
• Playboo execution success rate
• Response approval delay
• Rollback frequency
• Failed integration actions
• Percentage of containment actions completed through the XDR workflow

Whether response actions are fast, consistent, reliable, and safe. The objective is controlled automation, not maximum automation. 5. Business and Program Value

• Reduction in duplicated tools or capabilities
• Cost avoided through consolidation
• SOC capacity recovered
• Improvement in incident response readiness
• Audit evidence completeness
• Reduction in material security incidents
• Percentage of high-risk assets with validated detection coverage
• Improvement in service restoration time
• Security control gaps identified before an incident
• Executive confidence in reported security outcomes

Whether the XDR implementation is delivering measurable operational, financial, risk, and governance improvements.
