$5.13M
Average ransomware breach cost — and the ransom is the smaller line item.
Double-extortion is now the default playbook: encrypt the environment, exfiltrate the data, threaten public disclosure if the ransom isn't paid. Average breach cost $5.13M per IBM 2025, with downtime, regulator coordination, and customer notification driving the cost — not the ransom itself. 75% of organizations hit by ransomware in 2024–25 had a known unpatched vulnerability as the entry point.
