What is list management?
List management is the operational control of blocklists and allowlists: adding an identifier with a reason, applying it on later events, and removing it when the case is closed.
What belongs on a list
Naiza supports allowlists and denylists for device fingerprints, IPs, emails, and customer identifiers. Record the reason and investigation reference for each confirmed entry.
How Naiza applies it
Naiza applies lists during event evaluation, returning BLOCK for listed identifiers or the configured allowlist override. Keep a reason trail and combine lists with scores and rules for new traffic.
Governance
Allowlists expire. Denylists need an owner. An allowlisted stolen session is worse than a false REVIEW. See allowlist vs denylist.
Frequently asked questions
Answers about screening, risk signals, and Naiza integration.
What is a fraud list management API?
It lets you create and apply allowlists and denylists of identifiers so decisions stay consistent across login, payment, and payout events.
Should analysts add every chargeback to a denylist?
No. One dispute can be legitimate. List after confirmation, or use a customer-level REVIEW rule first.
Is a watchlist the same as a fraud denylist?
AML watchlists contain sanctions, PEP, and adverse-media entries. Fraud lists contain identifiers your team has confirmed abusive or trusted. Keep the source and reason visible in the investigation.
