Rules

Evaluate risk inline, not after the fact

Build velocity-based rules that return allow/deny/challenge verdicts in under 150ms, directly in your auth and checkout flows.

Sub-150ms verdicts

Rules execute and return a decision before your page finishes loading.

Sliding window counters

Count events per user, device, or IP over configurable rolling time windows.

Webhook triggers

Fire webhooks to Slack, PagerDuty, or your own endpoints when rules match.

Dry-run backtesting

Test new rules against historical traffic before enforcing them in production.

Flexibility

Complex conditions, instant results

Chain multiple conditions across email risk, IP reputation, device trust, and custom properties. The engine evaluates the full rule tree in a single pass, no matter how deep.

Multi-signal evaluation

Combine email, IP, domain, and device scores in a single rule with AND/OR logic.

Custom properties

Pass any business-specific field (plan type, cart value, user role) and use it in rule conditions.

Cascading rules

Stack rules in priority order. First match wins, or aggregate scores across the full chain.

Slack & PagerDuty alerts

Get notified instantly when high-risk events match your rule criteria.

Webhook delivery

POST structured payloads to any HTTP endpoint for custom downstream logic.

List management

Auto-add flagged entities (IPs, emails, devices) to blocklists or watchlists on match.

Automation

Wire rules to your stack

When a rule fires, the response isn't just a score. Trigger side effects that keep your team in the loop and your systems in sync.

Simulation

Ship rules with confidence

Validate rule behavior before it touches real users. Replay historical traffic, compare outcomes, and fine-tune thresholds in minutes.

Historical replay

Run new rules against past events to see how many would have triggered.

Threshold tuning

Adjust score thresholds and see the impact on true/false positive rates instantly.

Shadow mode

Deploy rules in observe-only mode. Log decisions without enforcing them.

Diff comparison

Compare two rule versions side by side to understand the delta before promoting.
