## Buyer questions

- Choose tools based on the abuse you need to catch, the web or mobile surface you protect, the decision your team must make, false positives, and integration cost.
- Free allowances are not directly comparable: vendors may count identifications, API calls, events, checks, or trial days, with different time periods.
- Some products return decisions; others return IDs, signals, or scores that need rules in your application.
- Run shortlisted vendors on the same representative traffic window where practical, recording detection yield and legitimate users incorrectly flagged.
