Risk-tier step-up rules + proofed actions + incident export.
Targeted step-up can reduce successful ATO outcomes by 15-50% (modeled).
Estimated loss avoided = exposed user actions x incident-rate proxy x (15-50%).
Step-up events + receipts + exportable incident pack.
Security everywhere kills conversion. Security at the right moment wins. JIL Sovereign Technologies, Inc.
What changed, and what was measured.
Account takeover attempts increased during growth; blunt MFA degraded conversion.
- Reduced takeover success (target KPI)
- Preserved conversion via targeted step-up
- Standardized incident evidence exports
Why this problem persists
Blunt MFA - requiring additional authentication on every action - degrades user conversion. But removing MFA creates takeover risk. The challenge is applying friction proportionally: more friction on high-risk actions, less on routine ones. In this scenario, the platform was experiencing growing account takeover attempts. Their initial response - adding MFA to every sensitive action - caused a measurable drop in user conversion. Removing MFA restored conversion but allowed takeover attempts to succeed at higher rates.
The JIL approach
JIL applied risk-tier step-up policies: routine actions proceed normally, while high-risk actions (withdrawals, beneficiary changes, large transfers) trigger proportional step-up authentication. Every step-up event produces an incident-ready evidence pack. The risk-tier engine evaluated actions against behavioral baselines, device trust scores, and action severity. Routine actions from trusted devices proceeded without friction. High-risk actions from new devices or unusual patterns triggered step-up challenges that produced complete evidence trails for incident response.
