Measure fraud likelihood using practical risk signals fast. Tune thresholds for your organization’s appetite easily. Export results, review drivers, and plan safer verification steps.
| Scenario | Signals | Expected band |
|---|---|---|
| Routine login | Known device, strong auth, low IP risk | Low |
| Account change | New device, VPN, recent password reset | Medium |
| Takeover attempt | Tor, emulator, many failures, mismatch | High |
The calculator converts each input into a normalized indicator between 0 and 1, where higher values mean higher risk. It then computes a weighted sum and applies a logistic scaling for smoother separation.
| Factor | Weight | Indicator meaning |
|---|---|---|
| Authentication strength | 0.14 | Weaker methods score higher risk |
| Device familiarity | 0.10 | Unknown or new devices score higher |
| Device integrity | 0.08 | Rooted or emulated environments score higher |
| IP reputation | 0.12 | High-risk networks and anonymizers score higher |
| Login velocity | 0.10 | More failures per hour increase risk |
| Breach exposure | 0.08 | Higher breach counts increase takeover odds |
| Account age | 0.08 | Newer accounts increase risk |
| Customer profile | 0.06 | New profiles are treated as riskier |
| Monetary value | 0.12 | Higher amounts/limits raise exposure |
| Geo distance | 0.05 | Large jumps can indicate spoofing |
| Recent changes | 0.05 | Resets or address changes raise risk |
| Identity proofing | 0.12 | Mismatches, weak checks, and new contact points raise risk |
Identity fraud risk rises when attackers combine fresh credentials, new devices, and monetizable events. High-value payments, payout requests, and profile changes create profitable windows, especially when recovery channels are weak. This calculator translates those conditions into comparable indicators so teams can triage consistently across channels and regions. It is a disciplined signal supporting consistent decisions.
The strongest signals usually come from authentication strength, device reputation, and network anonymity. Password-only access, SMS-only recovery, and shared devices increase takeover probability. New or inconsistent devices, emulators, and rooted environments add automation and evasion risk. Network factors such as Tor, VPN use, and poor IP reputation reduce traceability. Behavior signals also matter: rapid failed logins, sudden geo-distance jumps, and “change then spend” patterns often precede loss events.
Each input is normalized to a 0–1 risk indicator, then multiplied by a weight that reflects its relative influence on loss. Monetary value is log-scaled so a jump from 50 to 500 matters more than 5,000 to 5,450. The weighted sum is passed through a logistic curve to spread mid-range cases and avoid “all-or-nothing” scoring. Risk appetite adjusts the final score and the low/high thresholds used for banding, aligning controls to business tolerance. Review top driver contributions to explain outcomes and support audit discussions.
Low scores support frictionless approvals with logging and passive monitoring. Medium scores justify step-up checks, limits on sensitive changes, and short holds on withdrawals until verification completes. High scores indicate strong evidence or high exposure; route cases to manual review, require strong proofing, and add containment steps like session invalidation, credential reset, and device binding. Use export files to document the decision, inputs, and the recommended action list for stakeholders.
Track decision outcomes, false positives, and confirmed fraud to recalibrate weights and thresholds quarterly. Compare driver contributions to spot rule drift, such as rising VPN usage, increased mismatch rates, or higher breach exposure in a segment. Measure time-to-decision, review backlog, and step-up success to keep controls proportionate. Use the confidence score to prioritize follow-up when optional fields are missing, unknown, or inconsistent across sources.
It is a 0–100 relative risk signal built from your inputs. Higher scores mean more identity risk indicators are present and stronger controls are recommended.
Drivers are the weighted contributions of each factor to the raw score. The list highlights which inputs pushed the score upward the most for this submission.
Confidence reflects completeness of optional fields like geo distance and breach exposure. More filled, reliable signals raise confidence; missing or unknown values reduce it.
Use the risk appetite control as a starting point, then tune thresholds with historical outcomes. Balance fraud loss, customer friction, and review capacity for your workflow.
Hold the action, require stronger verification, and investigate device, IP, and mismatch indicators. Consider session invalidation and restricting profile changes until review completes.
Yes. Treat the default weights as a baseline. Recalibrate using confirmed fraud, false positives, and channel differences, then validate changes with controlled rollouts.
