Preventative Security in the Era of “Speed to Breach”: Why Time to Detection Is a Losing Metric 

The document outlines IBM X-Force findings that attackers increasingly use AI-driven, credential-based techniques and cloud-hosted phishing to move at machine speed, with infostealer campaigns surging and long dwell times driving higher breach costs, while many organizations lack crisis playbooks. It argues that traditional detect-and-respond metrics are insufficient and urges a prevention-first, deception-led approach, promoting Automated Moving Target Defense to preempt execution, block lateral movement, and reduce alert fatigue while complementing existing EDR/XDR in hybrid-cloud environments.
